Technical Field
The present invention relates to a vehicle driving support system.
Background
Conventionally, a turning direction indicating device that facilitates operation has been known (for example, see japanese unexamined patent publication No. 2006-117047). In this turning direction indicator, the lever is automatically returned to the neutral position when the lever is operated to swing, and the control means outputs the drive signal to the lighting device for only a predetermined time, so that the turn signal lamp is blinked for only the predetermined time when the turning operation angle of the steering wheel is small, such as a lane change.
In addition, conventionally, there is known a turn signal lighting control device for securing a correct lighting motion according to the intention of a user (for example, see japanese unexamined patent publication No. 2012-096708). In this turn signal lighting control device, when the instantaneous turn lever is operated, the operated one of the left and right turn signals is turned on, and when the turn-off condition of the turning signal being turned on is satisfied, the turn signal is turned off, and when the turn signal is automatically turned off, the turn signal is turned on by the turn lever operation for a predetermined period of time from the time point.
Japanese laid-open patent publication nos. 2006-117047 and 2012-096708 do not describe a case where a driver or the like is alerted in accordance with the situation of the rear side of the vehicle or the like.
If, for example, a swing operation of a right turn direction lever is required to cancel blinking of a turn signal in a left turn direction, there is a possibility that the driver will feel uncomfortable even if the driver does not intend to make a lane change to the right side and an auditory and/or tactile attention is given according to the situation of the right rear side of the vehicle.
In addition, for example, a driver who wants to return the lever to the neutral position in order to cancel the blinking of the turn signal in the left turn direction may erroneously operate the lever to the operation position in the right turn direction although the driver does not intend to make a lane change to the right side. In this case, if the auditory and/or tactile attention is given according to the situation of the right rear side of the vehicle, the driver or the like may feel uncomfortable as in the above case.
Disclosure of Invention
An aspect of the present invention provides a vehicle driving support system capable of suppressing the possibility of making an attention prompt of an undesired auditory sense and/or tactile sense of a driver or the like.
(1) A vehicle driving support system according to an aspect of the present invention includes: an operation unit that is provided so as to be operable from a neutral position to a first position on one side and a second position on the other side, and that is reset to the neutral position after the operation or when a predetermined condition is satisfied; a switch unit that outputs either an on signal or an off signal according to a position of the operation unit; a control unit that generates a steering signal based on an output of the switching unit; a detection unit that detects a situation of a rear side of the vehicle; and an attention calling unit that calls attention based on an output of an on signal of the switch unit and a detection result of the detection unit, the attention calling unit including: a visual attention reminder; and an auditory attention notifying unit and/or a tactile attention notifying unit, wherein the control unit executes at least one of a one-touch steering control that generates a steering signal during a first setting period and a maximum steering control (full turn control) that continues to generate the steering signal until the predetermined condition is satisfied, and the control unit executes at least one of a first control and a second control, the first control being: in the one-touch steering control corresponding to the first position, when the switch section outputs an on signal corresponding to the second position, the control section does not generate a steering signal corresponding to the second position, cancels the one-touch steering control corresponding to the first position, and performs visual attention calling only by the visual attention calling section of the attention calling section based on the output of the on signal corresponding to the second position and the detection result of the detection section, the second control being control of: when the switch unit outputs an on signal corresponding to the second position after the control unit generates a maximum turn signal (full turn signal) corresponding to the first position or generates a maximum turn signal corresponding to the first position, the control unit does not generate a turn signal corresponding to the second position, cancels the maximum turn control corresponding to the first position, and performs visual attention prompting only by the visual attention prompting unit based on the output of the on signal corresponding to the second position and the detection result of the detection unit.
(2) In the vehicle driving support system according to item (1) above, the visual attention notifying unit may include a first display unit provided in a mirror of the vehicle and/or a second display unit provided in a place displaced from a position of the steering device in the vehicle width direction.
(3) In the vehicle driving support system recited in (1) or (2), the control unit may generate a steering signal corresponding to the second position when a second setting period is set simultaneously with the start of the first control and the output of the on signal corresponding to the second position is continued after the second setting period elapses, and the audible attention reminder and/or the tactile attention reminder may perform audible and/or tactile attention reminder based on the output of the on signal corresponding to the second position and the detection result of the detection unit.
(4) In the vehicle driving support system recited in (3) above, in the first control, when the operating unit is operated again to the second position after the operation of returning the operating unit to the neutral position in the second setting period, a turn signal corresponding to the second position may be generated before the second setting period elapses, and the audible attention reminder and/or the tactile attention reminder may be caused to perform audible and/or tactile attention reminding based on an output of an on signal corresponding to the second position of the operating unit and a detection result of the detecting unit.
(5) In the vehicle driving support system recited in any one of (1) to (4), when the control unit sets a third setting period at the same time as the start of the second control and generates an output of an on signal corresponding to the second position after the third setting period elapses, the control unit may generate a turn signal corresponding to the second position, and the audible attention notifying unit and/or the tactile attention notifying unit may perform audible and/or tactile attention notifying based on the output of the on signal corresponding to the second position and the detection result of the detection unit.
(6) In the vehicle driving support system recited in (4) above, in the second control, when the operating unit is operated again to the second position after the operation of returning the operating unit to the neutral position in the third setting period, a turn signal corresponding to the second position may be generated before the third setting period elapses, and the audible attention reminder and/or the tactile attention reminder may be caused to perform audible and/or tactile attention reminding based on an output of an on signal corresponding to the second position of the operating unit and a detection result of the detecting unit.
(7) In the vehicle driving support system recited in (3) above, when the output of the on signal corresponding to the second position is continued after the second set period has elapsed, the control unit may generate a signal for operating a side illumination lamp that illuminates a side of the left and right sides of the vehicle corresponding to the turn signal corresponding to the second position.
(8) In the vehicle driving support system recited in (5) above, when the output of the on signal corresponding to the second position is generated after the third set period has elapsed, the control unit may generate a signal for operating a side illumination lamp that illuminates a side of the left and right sides of the vehicle corresponding to the turn signal corresponding to the second position.
When the switch unit outputs the on signal corresponding to the second position of the operation unit in the one-touch steering control corresponding to the first position of the operation unit, the following cases are included, for example: the driver of the vehicle may want to cancel the turn signal corresponding to the first position of the operation portion and may not want to generate the turn signal corresponding to the second position of the operation portion.
Therefore, in the vehicle driving support system according to the above (1), in such a case, the auditory attention notifying part and/or the tactile attention notifying part of the attention notifying part does not perform auditory and/or tactile attention notifying.
Therefore, in the vehicle driving support system described in (1), for example, it is possible to suppress the possibility of auditory and/or tactile attention being given when the driver of the vehicle does not wish to do so (for example, when only one-touch steering is desired to be cancelled).
On the other hand, in the vehicle driving support system described in the above (1), since the driver of the vehicle desiring to make a lane change to the other side is visually alerted at an early stage, for example, the safety can be improved. Since the driver's attention for a lane change is expected to be higher than in the case of normal driving, it is possible to sufficiently improve safety even in the case of an alarm that is only a visual attention reminder.
That is, in the vehicle driving support system described in the above (1), it is possible to simultaneously achieve a reduction in the sense of discomfort for a driver who does not desire a lane change and an improvement in the safety for a driver who desires a lane change.
In addition, when the control unit generates the maximum steering signal corresponding to the first position of the operation unit or generates the maximum steering signal corresponding to the first position of the operation unit, and then the switch unit outputs the on signal corresponding to the second position of the operation unit, the following cases are included: for example, a driver of the vehicle who wants to cancel the turn signal corresponding to the first position of the operation portion may erroneously operate the operation portion to the second position even though the driver does not intend to generate the turn signal corresponding to the second position of the operation portion.
Therefore, in the vehicle driving support system according to the above (1), in such a case, the auditory attention notifying part and/or the tactile attention notifying part of the attention notifying part does not perform auditory and/or tactile attention notifying.
Therefore, in the vehicle driving support system described in (1), for example, it is possible to suppress the possibility of auditory and/or tactile attention being given when the driver of the vehicle erroneously operates the operation unit. In other words, for example, it is possible to suppress the possibility of auditory and/or tactile attention being given to the driver of the vehicle when the driver does not wish to do so.
On the other hand, in the vehicle driving support system described in the above (1), since the driver of the vehicle desiring to make a lane change to the other side is visually alerted at an early stage, for example, the safety can be improved. Since the driver's attention for a lane change is expected to be higher than in the case of normal driving, it is possible to sufficiently improve safety even in the case of an alarm that is only a visual attention reminder.
That is, in the vehicle driving support system described in the above (1), it is possible to simultaneously achieve a reduction in the sense of discomfort for a driver who does not desire a lane change and an improvement in the safety for a driver who desires a lane change.
In the vehicle driving support system according to the above (2), the visual attention notifying unit may include a first display unit provided in a mirror of the vehicle and/or a second display unit provided in a place displaced from a position of the steering device in the vehicle width direction.
In the case where the visual attention notifying unit includes the first display unit and/or the second display unit, in the vehicle driving support system described in the above (2), the possibility that the driver has a sense of discomfort can be suppressed as compared with the case where the visual attention notifying unit provided at the vehicle width direction position of the steering apparatus performs the visual attention notifying. On the other hand, since the driver's attention for a lane change is desired to be improved as compared with the case of normal driving, it is possible to sufficiently improve safety by visually noticing the driver's attention to the mirror and/or the place displaced from the vehicle width direction position of the steering apparatus.
When the switch unit continues to output the on signal corresponding to the second position of the operation unit, or when the operation unit is operated again to the second position after the operation unit is returned to the neutral position in the second setting period, it can be estimated that, for example, the driver of the vehicle not only wants to cancel the steering signal corresponding to the first position of the operation unit but also generates the steering signal corresponding to the second position of the operation unit.
Therefore, in the vehicle driving support system recited in the above (3), after the second setting period has elapsed, the control unit may generate the steering signal in accordance with the second position of the operation unit, and the auditory attention notifying unit and/or the tactile attention notifying unit may perform auditory and/or tactile attention notifying based on an output of the on signal in accordance with the second position of the operation unit and a detection result of the detection unit.
In the vehicle driving support system according to (3), when the control unit generates the steering signal according to the second position of the operation unit after the second set period has elapsed, it is possible to satisfy a request of a driver of the vehicle, for example, for the generation of the steering signal according to the second position of the operation unit.
In addition, in the vehicle driving support system described in (3), when the auditory attention notifying unit and/or the tactile attention notifying unit performs auditory and/or tactile attention notifying after the second setting period has elapsed, safety can be improved as compared with a case where auditory and/or tactile attention notifying is not performed after the second setting period has elapsed.
In the vehicle driving support system described in (4), when the operating unit is operated again to the second position after the operation unit is reset to the neutral position in the second setting period, the first control may generate the turn signal corresponding to the second position before the second setting period elapses, and cause the audible and/or tactile attention notifying unit to perform the audible and/or tactile attention notifying based on an output of the on signal corresponding to the second position of the operating unit and a detection result of the detecting unit.
In the vehicle driving support system according to (4) above, when the first control generates the steering signal according to the second position before the second set period elapses, it is possible to satisfy a request of a driver of the vehicle, for example, for the generation of the steering signal according to the second position of the operation portion.
Further, in the case where the auditory attention notifying unit and/or the tactile attention notifying unit performs auditory and/or tactile attention notifying before the second setting period elapses, the vehicle driving support system described in (4) above can improve safety as compared with the case where auditory and/or tactile attention notifying is not performed before the second setting period elapses.
When the switch unit continues to output the on signal corresponding to the second position of the operation unit, or when the operation unit is operated again to the second position after the operation unit is returned to the neutral position in the third setting period, it can be estimated that the operation unit is not located at the second position due to an erroneous operation by the driver of the vehicle, for example, but the driver of the vehicle intends to generate the turn signal corresponding to the second position of the operation unit.
Therefore, in the vehicle driving support system recited in the above (5), after the third setting period has elapsed, the control unit may generate the steering signal corresponding to the second position of the operation unit, and the auditory attention notifying unit and/or the tactile attention notifying unit may perform auditory and/or tactile attention notifying based on an output of the on signal corresponding to the second position of the operation unit and a detection result of the detection unit.
In the vehicle driving support system according to (5) above, when the control unit generates the steering signal according to the second position of the operation unit after the third set period has elapsed, it is possible to satisfy a request of a driver of the vehicle, for example, for the generation of the steering signal according to the second position of the operation unit.
In the vehicle driving support system according to (5), when the auditory attention notifying unit and/or the tactile attention notifying unit performs auditory and/or tactile attention notifying after the third setting period has elapsed, safety can be improved as compared with a case where auditory and/or tactile attention notifying is not performed after the third setting period has elapsed.
In the vehicle driving support system described in (6), when the operating unit is operated again to the second position after the operation unit is reset to the neutral position in the third setting period, the second control may generate the turn signal corresponding to the second position before the third setting period elapses, and cause the audible and/or tactile attention notifying unit to perform the audible and/or tactile attention notifying based on the output of the on signal corresponding to the second position of the operating unit and the detection result of the detecting unit.
In the vehicle driving support system according to (6), when the second control generates the steering signal according to the second position before the third set period elapses, it is possible to satisfy a request of the driver of the vehicle, for example, for the generation of the steering signal according to the second position of the operation portion.
Further, in the case where the auditory attention notifying unit and/or the tactile attention notifying unit performs auditory and/or tactile attention notifying before the third setting period elapses, the vehicle driving support system described in (6) above can improve safety as compared with the case where auditory and/or tactile attention notifying is not performed before the third setting period elapses.
As described above, when the switch unit continues to output the on signal corresponding to the second position of the operation unit, it can be estimated that the driver of the vehicle wants to cancel the turn signal corresponding to the first position of the operation unit and generate the turn signal corresponding to the second position of the operation unit.
Therefore, in the vehicle driving support system recited in the above (7), the control unit may generate a signal for operating a side illumination lamp that illuminates the side of the left side and the right side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the second setting period elapses.
In the vehicle driving support system according to (7), in a case where the control unit generates a signal for operating a side lamp that irradiates light to the side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the second setting period has elapsed, safety can be improved as compared with a case where light is not irradiated to the side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the second setting period has elapsed.
As described above, when the switch unit continues to output the on signal corresponding to the second position of the operation unit, it can be estimated that the operation unit is not located at the second position due to an erroneous operation by the driver of the vehicle, for example, but the driver of the vehicle intends to generate the turn signal corresponding to the second position of the operation unit, for example.
Therefore, in the vehicle driving support system recited in the above (8), the control unit may generate a signal for operating a side illumination lamp that illuminates the side of the left side and the right side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the third setting period elapses.
In the vehicle driving support system according to (8) above, in a case where the control unit generates a signal for operating a side lamp that irradiates light to a side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the third setting period has elapsed, safety can be improved as compared with a case where light is not irradiated to the side of the vehicle corresponding to the turn signal corresponding to the second position of the operation unit after the third setting period has elapsed.

Detailed Description
Hereinafter, embodiments of a vehicle driving support system according to the present invention will be described with reference to the drawings.
Fig. 1 is a diagram showing an example of functions of a vehicle driving
In the example shown in fig. 1, the vehicle driving
The left turn signal V1 and the right turn signal V2 are configured in the same manner as the turn signal described in japanese laid-open patent publication No. 2015-11960, for example, and blink in response to an operation of the operation unit 11 to be described later.
The left side illumination lamp V3 and the right side illumination lamp V4 are configured in the same manner as the side illumination lamps described in japanese unexamined patent publication No. 2012-113947, for example. The left side illumination lamp V3 emits light to the left side of the vehicle V. The right side illumination lamp V4 illuminates the right side of the vehicle V.
The left side mirror V5 and the right side mirror V6 are configured in the same manner as the mirror unit described in Japanese patent application laid-open No. 2015-16708, for example. The left side mirror V5 is used for the driver of the driver V7 of the vehicle V to confirm the left rear of the vehicle V. The right side mirror V5 is used for the driver to confirm the right rear of the vehicle V.
In the example shown in fig. 1, the mirrors V5, V6 are door mirrors of the vehicle V, but in another example, the mirrors V5, V6 may be wing mirrors of the vehicle V.
In the example shown in fig. 1, the vehicle driving
The operation unit 11 is configured in the same manner as the second operation lever described in WO2013/160998, for example. The operation unit 11 is provided to a driver seat V7 of the vehicle V and is operated by the driver. The operation unit 11 includes a neutral position 11A, a first position 11B, and a second position 11C. The operation unit 11 is provided to be operable from the neutral position 11A to a first position 11B side (one side) and a second position 11C side (the other side).
The neutral position 11A is basically a position where the control unit 13 does not generate a steering signal.
The first position 11B is basically a position at which the control unit 13 generates a steering signal for turning the vehicle V left, for example. The second position 11C is basically a position at which the control unit 13 generates a steering signal for turning the vehicle V to the right, for example.
The operation unit 11 has a function of returning to the neutral position 11A after being operated to the first position 11B by the driver or satisfying a predetermined condition, and a function of returning to the neutral position 11A after being operated to the second position 11C by the driver or satisfying a predetermined condition. The term "after the predetermined condition is satisfied" includes, for example, after the driver manually cancels the condition described later, after the right and left turn is completed, and the like.
In the technique described in WO2013/160998, the second operation lever as the operation unit is disposed on the left side of the center axis of the steering shaft, but the operation unit 11 may be disposed on the left side of the center axis of the steering shaft or on the right side of the center axis of the steering shaft, as in the technique described in WO 2013/160998.
In the example shown in fig. 1, the switch unit 12 is configured similarly to, for example, a winker switch described in japanese laid-open patent publication 2008-162485 and a turn signal switch described in japanese laid-open patent publication 58-106714. The switch unit 12 changes the switch mode according to the position (the neutral position 11A, the first position 11B, and the second position 11C) of the operation unit 11.
For example, when the operation unit 11 is located at the neutral position 11A, the switch unit 12 basically outputs an OFF signal "Turn SW L OFF" (see fig. 2 (a)) (a signal for not causing the control unit 13 to generate a Turn signal for left turning and not causing the left Turn signal V1 to blink). When the operation unit 11 is located at the neutral position 11A, the switch unit 12 basically outputs an OFF signal "Turn SW R OFF" (see fig. 2 (C)) (a signal for not causing the control unit 13 to generate a Turn signal for turning right and not causing the right Turn signal V2 to blink).
When the operation unit 11 is located at the first position 11B, the switch unit 12 basically outputs an ON signal "Turn SW L ON" (see fig. 2 (a)) (a signal for causing the control unit 13 to generate a Turn signal for left turning and to blink the left Turn signal V1).
When the operation unit 11 is located at the second position 11C, the switch unit 12 basically outputs an ON signal "Turn SW R ON" (see fig. 2 (C)) (a signal for causing the control unit 13 to generate a Turn signal for right turning and to blink the right Turn signal V2).
In the example shown in fig. 1, the control section 13 generates a steering signal based on the signal output from the switch section 12. Specifically, when the switch unit 12 outputs the OFF signal "Turn SW L OFF", the control unit 13 basically does not generate the Turn signal for left Turn to blink the left Turn signal V1. When the switch unit 12 outputs the OFF signal "Turn SW R OFF", the control unit 13 basically does not generate the right Turn signal for blinking the right Turn signal lamp V2. When the switch unit 12 outputs the ON signal "Turn SW L ON", the control unit 13 basically generates the Turn signal "Turn LT L" for left Turn that blinks the left Turn signal lamp V1 (see fig. 2 (B)). When the switch unit 12 outputs the ON signal "Turn SW R ON", the control unit 13 basically generates the right Turn signal "Turn LT R" for blinking the right Turn signal lamp V2 (see fig. 3 (D)).
The control unit 13 includes a determination unit 13A. The determination unit 13A performs determination described later.
In the example shown in fig. 1, the operation unit 11 is of an alternate type, and the control unit 13 has a function of generating a one-touch steering signal "Turn LT L" (see fig. 2 (B)) to be described later.
The first position 11B of the operation portion 11 includes a holding position where the operation portion 11 is held at the first position 11B even if the driver takes the hand off the operation portion 11, and a non-holding position where the operation portion 11 is automatically reset to the neutral position 11A without being held at the first position 11B when the driver takes the hand off the operation portion 11.
The second position 11C of the operation portion 11 includes a holding position where the operation portion 11 is held at the second position 11C even if the driver takes the hand off the operation portion 11, and a non-holding position where the operation portion 11 is automatically reset to the neutral position 11A without being held at the second position 11C when the driver takes the hand off the operation portion 11.
When the driver moves the operation portion 11 to the holding position of the first position 11B, the operation portion 11 is held at the holding position of the first position 11B as described above. While the operation unit 11 is in the holding position of the first position 11B, the switch unit 12 outputs the ON signal "Turn SW L ON" (see fig. 4 a), the control unit 13 generates the left Turn steering signal (maximum steering signal) "Turn LT L" (see fig. 4B), and the left Turn signal V1 blinks.
Next, when the operation unit 11 is reset from the holding position of the first position 11B to the neutral position 11A, the signal output from the switch unit 12 is switched from the ON signal "Turn SW L ON" to the OFF signal "Turn SW L OFF" (refer to fig. 4 a), the control unit 13 does not generate the left Turn signal "Turn LT L" (refer to fig. 4B), and the left Turn signal lamp V1 is turned OFF.
When the driver moves the operation unit 11 to the holding position at the second position 11C, the operation unit 11 is held at the holding position at the second position 11C. While the operation unit 11 is in the holding position of the second position 11C, the switch unit 12 outputs the ON signal "Turn SW R ON", the control unit 13 generates the Turn signal for right turning (maximum Turn signal) "Turn LT R", and the right Turn signal lamp V2 blinks.
When the operation unit 11 is reset from the holding position of the second position 11C to the neutral position 11A, the signal output from the switch unit 12 is switched from the ON signal "Turn SW R ON" to the OFF signal "Turn SW R OFF", the control unit 13 does not generate the Turn signal "Turn LT R" for right turning, and the right Turn signal lamp V2 is turned OFF.
On the other hand, when the driver moves the operation unit 11 to the non-holding position of the first position 11B, as described above, when the driver takes his hand off the operation unit 11, the operation unit 11 is automatically reset from the non-holding position of the first position 11B to the neutral position 11A. While the operation unit 11 is located at the non-holding position of the first position 11B, the switch unit 12 outputs an ON signal "Turn SW L ON" (see fig. 2 a). The control unit 13 generates a left-Turn steering signal (one-touch steering signal) "Turn LT L" (see fig. 2B) not only while the operation unit 11 is located at the non-holding position of the first position 11B, but also while the operation unit 11 is reset to the neutral position 11A. While the control unit 13 generates the left Turn signal "Turn LT L", the left Turn signal lamp V1 blinks (for example, 3 times).
Next, when the control unit 13 does not generate the Turn signal "Turn LT L" for left turning any more, the left Turn signal lamp V1 is turned off.
When the driver moves the operation unit 11 to the non-holding position at the second position 11C, the operation unit 11 automatically returns from the non-holding position at the second position 11C to the neutral position 11A when the driver takes his hand off the operation unit 11. While the operation unit 11 is located at the non-holding position of the second position 11C, the switch unit 12 outputs the on signal "Turn SW RON". The control unit 13 generates a Turn signal for right turning (one-touch Turn signal) "Turn LT R" not only during the period in which the operation unit 11 is located at the non-holding position of the second position 11C but also during a period after the operation unit 11 is reset to the neutral position 11A. During the period in which the control unit 13 generates the Turn signal "Turn LT R" for right turning, the right Turn signal lamp V2 blinks (for example, 3 times).
Next, when the control unit 13 does not generate the Turn signal "Turn LT R" for right turning, the right Turn signal lamp V2 is turned off.
In another example, the operation unit 11 may be of a momentary type (a type not having the above-described holding position). In this example, the control unit 13 also has a function of generating a one-touch steering signal.
That is, the first position 11B of the momentary operation portion 11 includes only a non-holding position, and in this non-holding position, when the driver takes his hand off the operation portion 11, the operation portion 11 is automatically returned to the neutral position 11A without being held at the first position 11B.
In addition, the second position 11C of the momentary operation portion 11 includes only a non-holding position, and in this non-holding position, when the driver takes his hand off the operation portion 11, the operation portion 11 is automatically returned to the neutral position 11A without being held at the second position 11C.
In the example shown in fig. 1, the detection unit 14 detects the condition of the left rear side and the condition of the right rear side of the vehicle V. The detection unit 14 includes, for example, a camera 14A and a camera 14B. The cameras 14A and 14B are configured in the same manner as the cameras described in japanese unexamined patent application publication No. 2017-47817, for example. The camera 14A is disposed on, for example, the left side mirror V5, and captures an image of the situation on the left rear side of the vehicle V. The camera 14B is disposed on, for example, the right side mirror V6, and captures an image of the situation on the right rear side of the vehicle V.
In another example, the detection unit 14 may detect the left rear side and the right rear side of the vehicle V by a mechanism other than a camera, such as a rear sonar described in japanese patent application laid-open No. 2018-34654.
Fig. 10 is a diagram for explaining an example of the imaging range of the camera 14A disposed in the left side mirror V5.
In the example shown in fig. 10, the shooting range of the camera 14A is set to a range larger than the range that the driver of the vehicle V can confirm via the left side mirror V5.
In the example shown in fig. 1, the attention calling part 15 calls attention to, for example, the driver of the driver seat V7 of the vehicle V or the like based ON the output of the ON signals "Turn SW L ON" and "Turn SW R ON" of the switch part 12 and the detection result of the detection part 14. The attention calling unit 15 includes a visual attention calling unit 15A, an auditory attention calling unit 15B, and a tactile attention calling unit 15C.
The visual attention notifying unit 15A visually notifies the driver of the driver V7 of the vehicle V and the like, for example. The visual attention reminder 15A includes display units 15A1, 15A2, 15A3, and 15A 4. The display portions 15a1 and 15a2 are configured in the same manner as the indicators described in japanese laid-open patent publication No. 2015-16708, for example. The display unit 15a1 (first display unit) is provided on the left side mirror V5.
Fig. 9A to 9C are diagrams for explaining an example of the display unit 15a1 provided in the left side mirror V5. Specifically, fig. 9A is a diagram showing a part of the left side mirror V5. Fig. 9B is an enlarged view of the display portion 15a1 provided in the left side mirror V5. Fig. 9C is a diagram showing a relationship between the vehicle V and another vehicle present on the left rear side of the vehicle V.
In the example shown in fig. 9A to 9C, when the other vehicle existing ON the left rear side of the vehicle V is detected by the running detection unit 14 of the vehicle V (see fig. 9C) and the switch unit 12 outputs the ON signal "Turn SW L ON" (see fig. 4 a), the display unit 15A1 of the visual attention notifying unit 15A of the attention notifying unit 15 displays a warning (blinking display) (see fig. 9A and 9B).
In the example shown in fig. 1, the display unit 15a2 (first display unit) is provided on the right side mirror V6. The display portion 15a3 is configured in the same manner as the indicator described in japanese laid-open patent publication No. 2009-211499, for example.
The display unit 15a3 is provided in a place away from the front of the driver seat V7 in the interior of the vehicle V. Specifically, the display unit 15a3 is disposed, for example, below a front pillar (not shown) of the vehicle V. The display portion 15a4 is configured in the same manner as the display portion described in japanese unexamined patent application publication No. 2017-21441, for example.
Fig. 8 is a diagram for explaining the arrangement of the display unit 15a4 and the like.
In the example shown in fig. 8, the display unit 15a4 (second display unit) is provided at a position displaced from the vehicle width direction position of the steering apparatus ST.
In the example shown in fig. 1, the audible attention notifying unit 15B audibly notifies the driver of the driver V7 of the vehicle V or the like, for example. The auditory attention notifying unit 15B includes a speaker (not shown) configured in the same manner as the speaker described in japanese laid-open patent publication No. 2014-56295, for example.
The tactile attention notifying unit 15C gives a tactile attention notifying signal to, for example, a driver of the driver V7 of the vehicle V. The tactile attention notifying portion 15C includes a vibration applying device (not shown) configured in the same manner as the vibration applying device described in japanese unexamined patent publication No. 2018-62296, for example. The vibration applying device gives a tactile attention to the driver of the driver seat V7 of the vehicle V by vibrating a steering device, a seat, and the like, for example.
In the example shown in fig. 1, the attention calling part 15 includes a visual attention calling part 15A, an audible attention calling part 15B, and a tactile attention calling part 15C, but in another example, the attention calling part 15 may include the visual attention calling part 15A and the audible attention calling part 15B without including the tactile attention calling part 15C. In another example, the attention calling part 15 may be provided with a visual attention calling part 15A and a tactile attention calling part 15C, but not with an audible attention calling part 15B.
In the example shown in fig. 1, the vehicle driving
More specifically, when the camera 14A of the detection unit 14 captures an image of another vehicle present ON the left rear side of the vehicle V during the traveling of the vehicle V, or when the sonar or the like of the detection unit 14 detects another vehicle present ON the left rear side of the vehicle V (see fig. 9C), and when the switch unit 12 outputs the ON signal "Turn SW L ON", the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A displays a warning (blinking display). Further, when the camera 14B of the detection unit 14 captures an image of another vehicle present ON the right rear side of the vehicle V during traveling of the vehicle V, or when another vehicle present ON the right rear side of the vehicle V is detected by the sonar or the like of the detection unit 14 and the switch unit 12 outputs the ON signal "Turn SW R ON", the display unit 15A2 or the display unit 15A3 of the visual attention calling unit 15A of the attention calling unit 15 displays a warning (blinking display).
When the camera 14A of the detection unit 14 captures an image of another vehicle present on the left rear side of the vehicle V during the traveling of the vehicle V, or when the sonar or the like of the detection unit 14 detects another vehicle present on the left rear side of the vehicle V (see fig. 9C), and the control unit 13 generates the Turn signal "Turn LT L", the auditory attention notifying unit 15B of the attention notifying unit 15 outputs a warning sound. Further, when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V during the traveling of the vehicle V, or when another vehicle present on the right rear side of the vehicle V is detected by the sonar or the like of the detection unit 14 and the control unit 13 generates the Turn signal "Turn LT R", the auditory attention notifying unit 15B of the attention notifying unit 15 outputs a warning sound.
In the example shown in fig. 1, the vehicle driving
More specifically, when the switch unit 12 outputs the ON signal "Turn SW L ON" while the vehicle V is traveling, the display unit 15A4 (see fig. 8) of the visual attention notifying unit 15A of the attention notifying unit 15 displays an image of the situation (see fig. 10) of the left rear side of the vehicle V captured by the camera 14A of the detection unit 14. When the switch unit 12 outputs the ON signal "Turn SW R ON" during the running of the vehicle V, the display unit 15A4 of the visual attention notifying unit 15A of the attention notifying unit 15 displays an image of the situation ON the right rear side of the vehicle V captured by the camera 14B of the detection unit 14.
In the example shown in fig. 1, the vehicle driving
Specifically, when the control unit 13 generates the Turn signal "Turn LT L", the control unit 13 generates a signal to activate the left side lamp V3, and the left side lamp V3 is turned on to irradiate the left side of the vehicle V with light. When the control unit 13 generates the Turn signal "Turn LT R", the control unit 13 generates a signal to activate the right side lamp V4, and the right side lamp V4 is turned on to irradiate the right side of the vehicle V with light.
Fig. 2 is a diagram for explaining an example in which the control unit 13 generates the one-touch steering signal "Turn LT L" and then cancels the one-touch steering signal "Turn LT L". Specifically, fig. 2 (a) shows the ON signal "Turn SW L ON" and the OFF signal "Turn SW L OFF" for left-turning output from the switch unit 12. Fig. 2 (B) shows a left-Turn steering signal "Turn LT L" generated by the control unit 13. Fig. 2 (C) shows the ON signal "Turn SW R ON" and the OFF signal "Turn SW R OFF" for turning right output from the switch unit 12. Fig. 2 (D) shows a right-Turn steering signal "Turn LT R" generated by the control unit 13. Fig. 2 (E) shows the state (blinking or extinguishing) of the left turn signal lamp V1. Fig. 2 (F) shows the state (blinking or extinction) of the right turn signal lamp V2. Fig. 2G shows a state (on or off) of the right side lateral illumination lamp V4.
Fig. 2 (H) shows a state (blinking display or non-display) of the display unit 15A2 or the display unit 15A3 of the visual attention calling unit 15A. Fig. 2 (I) shows the state of the auditory attention notifying unit 15B (whether the warning sound is being output or not being output). Fig. 2 (J) shows a state (image display or non-display) of the display unit 15A4 of the visual attention calling unit 15A.
In the example shown in fig. 2, determination unit 13A of control unit 13 determines whether or not determination period DP1 (see fig. 2 a), which is a period during which switch unit 12 outputs ON signal "Turn SW L ON" (see fig. 2 a), is equal to or longer than set period SP1 (e.g., 1000 ms) (see fig. 2 a).
When the determination period DP1 is shorter than the set period SP1, the control unit 13 executes the one-touch steering control (the control shown in fig. 2) that generates the steering signal (the one-touch steering signal) "Turn LT L" (see fig. 2B) during the set period SP2 (see fig. 2B) that is longer than the
In the example shown in fig. 2, at time t1, the driver moves the operation portion 11 to the non-holding position of the first position 11B. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SWL ON" (see fig. 2 a). Along with this, the control unit 13 starts generating the steering signal "Turn LT L" for left turning corresponding to the first position 11B of the operation unit 11 (see fig. 2 (B)). Accordingly, the left turn signal lamp V1 starts to blink (see fig. 2E).
In the example shown in fig. 2, at time t1, the camera 14A of the detection unit 14 does not capture an image of another vehicle present on the left rear side of the vehicle V, and therefore the left side lamp V3 is not turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A does not start blinking, and the auditory attention calling unit 15B does not start outputting the warning sound.
On the other hand, in another example, at time t1, when the camera 14A of the detection unit 14 captures an image of another vehicle present on the left rear side of the vehicle V, the left side lamp V3 is turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A starts blinking, and the auditory attention calling unit 15B starts outputting a warning sound.
In the example shown in fig. 2, next, at time t2, the output from the switch unit 12 is switched from the ON signal "Turn SW L ON" to the OFF signal "Turn SW L OFF" (see fig. 2 (a)). Determination unit 13A of control unit 13 determines that determination period DP1 (time t1 to time t2) during which switch unit 12 outputs ON signal "Turn SW L ON" is smaller than set period SP1 (time t1 to time t 3). As a result, the control unit 13 continues to generate the left-turning steering signal (one-touch steering signal) "Turn LT L" (see fig. 2B) even after the time t 2. Specifically, the control unit 13 blinks the left turn signal lamp V1 3 times.
Next, at time t4 in the setting period SP2 (time t1 to time t5) (see fig. 2B) during which the control unit 13 generates the left-turning one-touch steering signal "Turn LT L" (see fig. 2B), the driver cancels the left-turning one-touch steering signal "Turn LT L" (see fig. 2B) (that is, the one-touch steering control is cancelled). Specifically, the driver moves the operation unit 11 to, for example, the non-holding position of the second position 11C. That is, the driver performs the one-touch steering operation for right turning (i.e., in the opposite direction). Accordingly, the left turn signal lamp V1 is turned off (see fig. 2E). Further, the switch unit 12 starts outputting the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 (see fig. 2 (C)). On the other hand, the control unit 13 does not start generating the steering signal "Turn LT R" for right turning corresponding to the second position 11C of the operation unit 11 (see fig. 2 (D)). Therefore, the right turn signal lamp V2 does not start blinking (see fig. 2F). The right side lateral lamp V4 is not turned on (see fig. 2G).
When the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V at time t4, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A starts blinking display (see fig. 2 (H)). On the other hand, even when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V, the auditory attention notifying unit 15B does not start outputting the warning sound (see fig. 2 (I)).
At time t4, display unit 15A4 of visual attention notifying unit 15A starts displaying an image of the right rear side situation of vehicle V captured by camera 14B of detection unit 14 (see fig. 2 (J)).
In another example, the timing at which display unit 15a2 or display unit 15A3 starts blinking and/or the timing at which display unit 15a4 starts displaying an image may be different from time t4 by a time lag, for example.
In the example shown in fig. 2, next, at time t6, operation unit 11 is reset to neutral position 11A. Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW R ON" to the OFF signal "Turn SW R OFF" (see fig. 2 (C)). Determination unit 13A of control unit 13 determines whether or not determination period DP2 (time t4 to time t6) (see fig. 2C) during which switch unit 12 outputs ON signal "Turn SW R ON" in accordance with second position 11C of operation unit 11 is equal to or longer than set period SP3 (e.g., 350[ ms ]) (see fig. 2C)). Specifically, the determination unit 13A determines that the determination period DP2 (time t4 to time t6) is smaller than the set period SP 3. As a result, after time t6, the control unit 13 does not generate the right Turn signal "Turn LT R" corresponding to the second position 11C of the operation unit 11 (see fig. 2D), and the right Turn signal lamp V2 does not start blinking (see fig. 2F).
At time t6, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A terminates the blinking display (see fig. 2H).
At time t6, the display unit 15A4 of the visual attention notifying unit 15A ends the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 2 (J)).
That is, in the example shown in fig. 2, in the setting period SP2 (time t1 to time t5) during which the left-Turn steering signal "Turn LT L" corresponding to the first position 11B of the operation unit 11 is generated, when the switch unit 12 outputs the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11, the determination unit 13A determines whether or not the determination period DP2 (time t4 to time t6) that is a period during which the switch unit 12 outputs the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 is equal to or greater than the setting period SP 3.
When the determination period DP2 (time t4 to time t6) is smaller than the set period SP3, it can be estimated that the driver of the vehicle V wants to cancel the Turn signal "Turn LTL" for the left Turn corresponding to the first position 11B of the operation unit 11, does not want to generate the Turn signal "Turn LT R" for the right Turn corresponding to the second position 11C of the operation unit 11, and does not want the attention calling of auditory sense and/or tactile sense, for example.
Therefore, in the example shown in fig. 2, when the determination period DP2 (time t4 to time t6) is shorter than the set period SP3, the auditory attention calling part 15B and/or the tactile attention calling part 15C of the attention calling part 15 do not perform auditory and/or tactile attention calling.
Therefore, in the example shown in fig. 2, for example, it is possible to suppress the possibility of auditory and/or tactile attention being given when the driver of the vehicle V does not wish.
In the example shown in fig. 2, at time t4 to time t6, only the visual attention notifying unit 15A (more specifically, the display unit 15A2 or the display unit 15A3 and the display unit 15A4) of the attention notifying unit 15 performs visual attention notifying based ON the output of the ON signal "Turn SW R ON" (see fig. 2C) corresponding to the second position 11C of the operation unit 11 and the detection result (the image of another vehicle present ON the right rear side of the vehicle V) of the detection unit 14.
In the example shown in fig. 2, from time t4 to time t6, the display unit 15a2 provided in the right side mirror V6 or the display units 15A3 and 15a4 provided in the interior of the vehicle V at a position away from the front of the driver seat V7 are visually alerted.
Therefore, in the example shown in fig. 2, the possibility that the driver has a sense of incongruity can be suppressed as compared with the case where the visual attention is reminded in front of the driver seat V7.
Fig. 3 is a diagram for explaining another example in which the control portion 13 generates the one-touch steering signal "Turn LT L" and then cancels the one-touch steering signal "Turn LT L". Specifically, fig. 3 (a) shows the ON signal "Turn SW L ON" and the OFF signal "Turn SW L OFF" for left-turning output from the switch unit 12. Fig. 3 (B) shows a left-Turn steering signal "Turn LT L" generated by the control unit 13. Fig. 3 (C) shows the ON signal "Turn SW R ON" and the OFF signal "Turn SW R OFF" for turning right output from the switch unit 12.
Fig. 3 (D) shows a right-Turn steering signal "Turn LT R" generated by the control unit 13. Fig. 3 (E) shows the state (blinking or extinguishing) of the left turn signal lamp V1. Fig. 3 (F) shows the state (blinking or extinction) of the right turn signal lamp V2. Fig. 3G shows a state (on or off) of the right side lateral illumination lamp V4. Fig. 3 (H) shows a state (blinking display or non-display) of the display unit 15A2 or the display unit 15A3 of the visual attention calling unit 15A. Fig. 3 (I) shows the state of the auditory attention notifying unit 15B (whether the warning sound is being output or not being output). Fig. 3 (J) shows a state (image display or non-display) of the display unit 15A4 of the visual attention calling unit 15A.
In the example shown in fig. 3, similarly to the example shown in fig. 2, determination unit 13A of control unit 13 determines whether or not a determination period DP1 (see fig. 3A), which is a period in which switch unit 12 outputs ON signal "Turn SW L ON" (see fig. 3A), is equal to or longer than set period SP1 (e.g., 1000 ms) (see fig. 3A).
When the determination period DP1 is shorter than the set period SP1, the control unit 13 executes the one-touch steering control (the control shown in fig. 3) that generates the steering signal (the one-touch steering signal) "Turn LT L" (see fig. 3B) during the set period SP2 (see fig. 3B) that is longer than the
In the example shown in fig. 3, at time t11, the driver moves the operation portion 11 to the non-holding position of the first position 11B. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SW L ON" (see fig. 3 a). Along with this, the control unit 13 starts generating the steering signal "Turn LT L" for left turning corresponding to the first position 11B of the operation unit 11 (see fig. 3 (B)). Accordingly, the left turn signal lamp V1 starts to blink (see fig. 3E).
In the example shown in fig. 3, at time t11, the camera 14A of the detection unit 14 does not capture an image of another vehicle present on the left rear side of the vehicle V, and therefore the left side lamp V3 is not turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A does not start blinking, and the auditory attention calling unit 15B does not start outputting the warning sound.
On the other hand, in another example, at time t11, when the camera 14A of the detection unit 14 captures an image of another vehicle present on the left rear side of the vehicle V, the left side lamp V3 is turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A starts blinking, and the auditory attention calling unit 15B starts outputting a warning sound.
In the example shown in fig. 3, next, at time t12, the output from the switch unit 12 is switched from the ON signal "Turn SW L ON" to the OFF signal "Turn SW L OFF" (see fig. 3 (a)). Determination unit 13A of control unit 13 determines that determination period DP1 (time t11 to time t12) during which switch unit 12 outputs ON signal "Turn SW L ON" is smaller than set period SP1 (time t11 to time t 13). As a result, the control unit 13 continues to generate the left-turning steering signal (one-touch steering signal) "Turn LT L" (see fig. 3B) even after time t 12. Specifically, the control unit 13 blinks the left turn signal lamp V1 3 times.
Next, at time t14 in the setting period SP2 (time t11 to time t15) (see fig. 3B) in which the left-turning one-touch steering signal "Turn LT L" is generated, the control unit 13 cancels the left-turning one-touch steering signal "Turn LT L" (see fig. 3B) (that is, the one-touch steering control is cancelled). Specifically, the driver moves the operation unit 11 to, for example, the non-holding position of the second position 11C. Accordingly, the left turn signal lamp V1 is turned off (see fig. 3E). Further, the switch unit 12 starts outputting the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 (see fig. 3 (C)). On the other hand, the control unit 13 has not yet started generating the steering signal "Turn LT R" for right turning according to the second position 11C of the operation unit 11 (see fig. 3D). Therefore, the right turn signal lamp V2 has not yet started flashing (see fig. 3F). The right side lateral lamp V4 is not yet turned on (see fig. 3G).
When the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V at time t14, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A starts blinking display (see fig. 3 (H)). On the other hand, even when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V, the auditory attention notifying unit 15B does not start outputting the warning sound (see fig. 3 (I)).
At time t14, display unit 15A4 of visual attention notifying unit 15A starts displaying an image of the right rear side situation of vehicle V captured by camera 14B of detection unit 14 (see fig. 3 (J)).
Next, determination unit 13A of control unit 13 determines whether or not determination period DP2 (time t14 to time t17) during which switch unit 12 outputs ON signal "Turn SW R ON" in accordance with second position 11C of operation unit 11 is equal to or greater than set period SP3 (e.g., 350[ ms ]) (see fig. 3 (C)). Specifically, at time t16, determination unit 13A determines that determination period DP2 (time t14 to time t17) is equal to or greater than set period SP 3. As a result, at time t16, the control unit 13 starts generating the right-Turn steering signal "Turn LTR" corresponding to the second position 11C of the operation unit 11 (see fig. 3D). Accordingly, the right turn signal lamp V2 starts to blink (see fig. 3F). The right side lateral lamp V4 is turned on (see fig. 3G).
At time t16, the auditory attention notifying unit 15B starts outputting a warning sound (see fig. 3 (I)).
The blinking display of the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A is continued (see fig. 3 (H)), and the display unit 15A4 of the visual attention notifying unit 15A continues the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 3 (J)).
In another example, the timing at which the right side lamp V4 is turned on and/or the timing at which the auditory attention notifying unit 15B starts outputting the warning sound may be different from the time t16 by a time lag, for example.
In the example shown in fig. 3, next, at time t17, operation unit 11 is reset to neutral position 11A.
Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW R ON" to the OFF signal "Turn SW R OFF" (see fig. 3 (C)). Accordingly, the control unit 13 does not generate the right Turn steering signal "Turn LT R" (see fig. 3D). Accordingly, the right turn signal lamp V2 is turned off (see fig. 3F). The right side lateral lamp V4 is also turned off (see fig. 3G).
At time t17, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A terminates the blinking display (see fig. 3H), and the auditory attention notifying unit 15B terminates the output of the warning sound (see fig. 3I).
At time t17, the display unit 15A4 of the visual attention notifying unit 15A ends the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 3J).
When the determination period DP2 (time t14 to time t17) is equal to or longer than the setting period SP3 (see fig. 3C), that is, when the output of the ON signal "Turn SW R ON" is continued after the lapse of the setting period SP3 (time t14 to time t16), it can be estimated that, for example, the driver of the vehicle V wants to cancel not only the left-turning steering signal "Turn LT L" (see fig. 3B) corresponding to the first position 11B of the operation unit 11 but also the right-turning steering signal "Turn LT R" (see fig. 3D).
Therefore, in the example shown in fig. 3, as described above, when the determination period DP2 (time t14 to time t17) is equal to or longer than the set period SP3 (see fig. 3C), that is, when the ON signal "Turn SW R ON" continues to be output after the set period SP3 (time t14 to time t16) elapses, the control unit 13 generates the right-Turn steering signal "Turn lt R" (see fig. 3D). Therefore, the request of the driver of the vehicle V who wants to generate the right Turn steering signal "Turn LT R" can be satisfied.
In the example shown in fig. 3, when the determination period DP2 (time t14 to time t17) is equal to or longer than the set period SP3 (see fig. 3C), that is, when the output of the ON signal "Turn SW R ON" continues after the set period SP3 (time t14 to time t16) elapses, the auditory attention notifying unit 15B performs auditory attention notifying based ON the output of the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 (see fig. 3C) and the detection result of the camera 14B of the detection unit 14 (the image of another vehicle present in the right rear side of the vehicle V). Therefore, safety can be improved as compared with a case where the attention calling is not performed by the attention calling part 15.
In the example shown in fig. 3, the tactile attention notifying unit 15C does not perform the tactile attention notifying at time t16, but in another example, the tactile attention notifying unit 15C may perform the tactile attention notifying at time t 16.
In the example shown in fig. 3, when the determination period DP2 (time t14 to time t17) is equal to or longer than the set period SP3 (see fig. 3C), that is, when the output of the ON signal "Turn SW R ON" is continued after the set period SP3 (time t14 to time t16) has elapsed, the control unit 13 generates a signal for operating the right side lamp V4 in accordance with the Turn signal "Turn LTR" for right turning (see fig. 3D), and accordingly, the right side lamp V4 is turned ON.
Therefore, safety can be improved as compared with the case where the right side illumination lamp V4 is not turned on at time t 16.
In the example shown in fig. 3, the driver moves operation unit 11 to second position 11C only once at the start of set period SP3 (time t14 to time t16), but in another example, the driver moves operation unit 11 twice during set period SP3 (time t14 to time t 16). Specifically, after the operation unit 11 is reset to the neutral position 11A in the setting period SP3, the operation unit 11 is operated to the second position 11C again. As a result, in this example, the control unit 13 generates the right Turn steering signal "Turn LT R" before the set period SP3 passes (before the time t 16). Further, before the set period SP3 elapses (before the time t16), when the camera 14B of the detection unit 14 captures an image of another vehicle present ON the right rear side of the vehicle V, the auditory attention notifying unit 15B starts outputting the warning sound based ON the output of the ON signal "Turn SW R ON".
Fig. 4 is a diagram for explaining an example in which the operator of the vehicle V, in which the control unit 13 generates the maximum steering signal "Turn LT L" and then wants to cancel the maximum steering signal "Turn LT L", erroneously operates the operation unit 11 to the second position 11C.
Specifically, fig. 4 (a) shows the ON signal "Turn SW L ON" and the OFF signal "Turn SW L OFF" for left-turning output from the switch unit 12. Fig. 4 (B) shows a left-Turn steering signal "Turn LTL" generated by the control unit 13.
Fig. 4 (C) shows the ON signal "Turn SW R ON" and the OFF signal "Turn SW R OFF" for turning right output from the switch unit 12. Fig. 4 (D) shows a right-Turn steering signal "Turn LT R" generated by the control unit 13. Fig. 4 (E) shows the state (blinking or extinguishing) of the left turn signal lamp V1. Fig. 4 (F) shows the state (blinking or extinction) of the right turn signal lamp V2. Fig. 4G shows a state (on or off) of the right side lateral illumination lamp V4. Fig. 4H shows a state (blinking display or non-display) of the display unit 15A2 or the display unit 15A3 of the visual attention calling unit 15A. Fig. 4 (I) shows the state of the auditory attention notifying unit 15B (whether the warning sound is being output or not being output). Fig. 4 (J) shows a state (image display or non-display) of the display unit 15A4 of the visual attention calling unit 15A.
In the example shown in fig. 4, determination unit 13A of control unit 13 determines whether or not determination period DP1 (see fig. 4 a), which is a period during which switch unit 12 outputs ON signal "Turn SW L ON" (see fig. 4 a), is equal to or longer than set period SP1 (e.g., 1000 ms) (see fig. 4 a).
When the determination period DP1 is equal to or longer than the set period SP1, the control unit 13 executes the maximum steering control (the control shown in fig. 4) that generates the steering signal (the maximum steering signal) "Turn LTL" (see fig. 4B) during the determination period DP1 (see fig. 4 a).
In the example shown in fig. 4, at time t21, the driver moves the operation unit 11 to the holding position at the first position 11B. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SW L ON" (see fig. 4 a). Along with this, the control unit 13 starts generating the steering signal "Turn LT L" for left turning corresponding to the first position 11B of the operation unit 11 (see fig. 4 (B)). Accordingly, the left turn signal lamp V1 starts to blink (see fig. 4E).
In the example shown in fig. 4, at time t21, the camera 14A of the detection unit 14 does not capture an image of another vehicle present on the left rear side of the vehicle V, and therefore the left side lamp V3 is not turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A does not start blinking, and the auditory attention calling unit 15B does not start outputting the warning sound.
On the other hand, in another example, at time t21, when the camera 14A of the detection unit 14 captures an image of another vehicle present on the left rear side of the vehicle V, the left side lamp V3 is turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A starts blinking, and the auditory attention calling unit 15B starts outputting a warning sound.
In the example shown in fig. 4, determination period DP1 (time t21 to time t23) during which determination unit 13A of control unit 13 determines that switch unit 12 outputs ON signal "Turn SW L ON" is equal to or longer than set period SP1 (time t21 to time t22) at time t 22.
Next, at time t23, the predetermined condition described above is satisfied, and the operation unit 11 moves from the first position 11B to the neutral position 11A. Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW L ON" to the OFF signal "Turn SW L OFF" (see fig. 4 (a)). Accordingly, the control unit 13 does not generate the left-Turn steering signal "Turn LTL" (see fig. 4B). Accordingly, the left turn signal lamp V1 is turned off (see fig. 4E).
That is, in the example shown in fig. 4, the control unit 13 continues to generate the left-turning steering signal "Turn LT L" until the predetermined condition described above is satisfied (until time t 23).
Next, at time t24, the driver of the vehicle V who wants to cancel the maximum steering signal "Turn LT L" (see fig. 4 (B)) erroneously moves the operation portion 11 from the neutral position 11A to the second position 11C. That is, the driver erroneously performs the one-touch steering operation for the right turn. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 (see fig. 4 (C)). On the other hand, the control unit 13 does not start generating the steering signal "Turn LT R" for right turning corresponding to the second position 11C of the operation unit 11 (see fig. 4 (D)). Therefore, the right turn signal lamp V2 does not start blinking (see fig. 4F). The right side lateral lamp V4 is not turned on (see fig. 4G).
In the example shown in fig. 4, the operation unit 11 is moved to the second position 11C at time t24 after the generation of the maximum steering signal "Turn LT L" (see fig. 4 (B)), but in another example, the operation unit 11 may be moved to the second position 11C during the generation of the maximum steering signal "Turn LT L" (see fig. 4 (B)). In this example, the maximum steering control corresponding to the first position 11B of the operation portion 11 is cancelled at the time point when the operation portion 11 is moved to the second position 11C.
In the example shown in fig. 4, at time t24, when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A starts blinking display (see fig. 4 (H)). On the other hand, even when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V, the auditory attention notifying unit 15B does not start outputting the warning sound (see fig. 4 (I)).
At time t24, display unit 15A4 of visual attention notifying unit 15A starts displaying an image of the right rear side situation of vehicle V captured by camera 14B of detection unit 14 (see fig. 4 (J)).
In another example, the timing at which display unit 15a2 or display unit 15A3 starts blinking and/or the timing at which display unit 15a4 starts displaying an image may be different from time t24 by a time lag, for example.
In the example shown in fig. 4, next, at time t25, the operation unit 11 is reset from the second position 11C to the neutral position 11A. Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW R ON" to the OFF signal "Turn SW R OFF" (see fig. 4 (C)).
Determination unit 13A of control unit 13 determines whether or not switch unit 12 continues to output on signal "Turn SW RON" corresponding to second position 11C of operation unit 11 in determination period DP3 (see fig. 4C) after the time point (time t25) at which set period SP4 (time t23 to time t25) has elapsed from the end time point (time t23) of determination period DP1 (time t21 to time t 23). Specifically, the determination unit 13A determines that the switch unit 12 does not continue to output the ON signal "Turn SW R ON" in the determination period DP3 (see fig. 4C). As a result, after time t25, the control unit 13 does not generate the right Turn signal "Turn LT R" corresponding to the second position 11C of the operation unit 11 (see fig. 4D), and the right Turn signal lamp V2 does not start blinking (see fig. 4F).
At time t25, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A terminates the blinking display (see fig. 4H).
At time t25, the display unit 15A4 of the visual attention notifying unit 15A ends the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 4 (J)).
That is, in the example shown in fig. 4, when the switch unit 12 outputs the ON signal "Turn SW R ON" (see fig. 4 (C)) corresponding to the second position 11C of the operation unit 11 after the control unit 13 generates the Turn signal "Turn LT L" (see fig. 4 (B)) for left-turning corresponding to the first position 11B of the operation unit 11 in the determination period DP1 (time t21 to time t23), the determination unit 13A determines whether or not the switch unit 12 continues to output the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 in the determination period DP3 which is a period after the time (time t25) of the setting period SP4 (time t23 to time t25) elapses from the end time (time t23) of the
If the switch unit 12 does not continue to output the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 during the determination period DP3, it can be estimated that the driver of the vehicle V who wants to cancel the Turn signal "Turn LT L" (see fig. 4B) for left-turning corresponding to the first position 11B of the operation unit 11 has erroneously operated the operation unit 11 to the second position 11C despite not having the intention of generating the Turn signal "Turn LT R" (see fig. 4D) corresponding to the second position 11C of the operation unit 11.
Therefore, in the example shown in fig. 4, when the switch unit 12 does not continue to output the ON signal "Turn SW R ON" (see fig. 4 (C)) corresponding to the second position 11C of the operation unit 11 during the determination period DP3 (after time t25), the auditory attention calling unit 15B and/or the tactile attention calling unit 15C in the attention calling unit 15 do not perform auditory and/or tactile attention calling.
Therefore, in the example shown in fig. 4, it is possible to suppress the possibility of auditory and/or tactile attention being given when the driver of the vehicle V erroneously operates the operation unit 11. In other words, it is possible to suppress the possibility of auditory and/or tactile attention being given when the driver of the vehicle V does not wish to do so.
In the example shown in fig. 4, at time t24 to time t25, only the visual attention notifying unit 15A (more specifically, the display unit 15A2 or the display unit 15A3 and the display unit 15A4) of the attention notifying unit 15 performs visual attention notifying based ON the output of the ON signal "Turn SW R ON" (see fig. 4C) corresponding to the second position 11C of the operation unit 11 and the detection result (the image of another vehicle present ON the right rear side of the vehicle V) of the detection unit 14.
In the example shown in fig. 4, from time t24 to time t25, the display unit 15a2 provided in the right side mirror V6 or the display units 15A3 and 15a4 provided in the interior of the vehicle V at a position away from the front of the driver seat V7 are visually alerted.
Therefore, in the example shown in fig. 4, the possibility that the driver has a sense of incongruity can be suppressed as compared with the case where the visual attention is reminded in front of the driver seat V7.
Fig. 5 is a diagram for explaining an example in which the driver of the vehicle V, in which the control unit 13 generates the maximum steering signal "Turn LT L" for left turning and then intends to generate the steering signal "Turn LT R" for right turning, operates the operation unit 11.
Specifically, fig. 5 (a) shows the ON signal "Turn SW L ON" and the OFF signal "Turn SW L OFF" for left-turning output from the switch unit 12. Fig. 5 (B) shows a left-Turn steering signal "Turn LTL" generated by the control unit 13.
Fig. 5 (C) shows the ON signal "Turn SW R ON" and the OFF signal "Turn SW R OFF" for turning right output from the switch unit 12. Fig. 5 (D) shows a right-Turn steering signal "Turn LT R" generated by the control unit 13. Fig. 5 (E) shows the state (blinking or extinguishing) of the left turn signal lamp V1. Fig. 5 (F) shows the state (blinking or extinction) of the right turn signal lamp V2. Fig. 5G shows a state (on or off) of the right side lateral illumination lamp V4. Fig. 5 (H) shows a state (blinking display or non-display) of the display unit 15A2 or the display unit 15A3 of the visual attention calling unit 15A. Fig. 5 (I) shows the state of the auditory attention notifying unit 15B (whether the warning sound is being output or not being output). Fig. 5 (J) shows a state (image display or non-display) of the display unit 15A4 of the visual attention calling unit 15A.
In the example shown in fig. 5, similarly to the example shown in fig. 4, determination unit 13A of control unit 13 determines whether or not a determination period DP1 (see fig. 5 a), which is a period in which switch unit 12 outputs ON signal "Turn SW L ON" (see fig. 5 a), is equal to or longer than set period SP1 (e.g., 1000 ms) (see fig. 5 a).
When the determination period DP1 is equal to or longer than the set period SP1, the control unit 13 executes the maximum steering control (the control shown in fig. 5) that generates the steering signal (the maximum steering signal) "Turn LT L" (see fig. 5B) during the determination period DP1 (see fig. 5 a).
In the example shown in fig. 5, at time t31, the driver moves the operation unit 11 to the holding position at the first position 11B. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SW L ON" (see fig. 5 a). Along with this, the control unit 13 starts generating the steering signal "Turn LT L" for left turning corresponding to the first position 11B of the operation unit 11 (see fig. 5 (B)). Accordingly, the left turn signal lamp V1 starts to blink (see fig. 5E).
In the example shown in fig. 5, at time t31, the camera 14A of the detection unit 14 does not capture an image of another vehicle present on the left rear side of the vehicle V, and therefore the left side lamp V3 is not turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A does not start blinking, and the auditory attention calling unit 15B does not start outputting the warning sound.
On the other hand, in another example, at time t31, when the camera 14A of the detection unit 14 captures an image of another vehicle present on the left rear side of the vehicle V, the left side lamp V3 is turned on, the display unit 15A1 or the display unit 15A3 of the visual attention calling unit 15A starts blinking, and the auditory attention calling unit 15B starts outputting a warning sound.
In the example shown in fig. 5, at time t32, the above-described predetermined condition is satisfied, and determination period DP1 (time t31 to time t33) during which determination unit 13A of control unit 13 determines that switch unit 12 outputs ON signal "Turn SW L ON" is equal to or longer than setting period SP1 (time t31 to time t 32).
Next, at time t33, the operation unit 11 moves from the first position 11B to the neutral position 11A. Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW L ON" to the OFF signal "Turn SW L OFF" (see fig. 5 (a)). Accordingly, the control unit 13 does not generate the left-Turn steering signal "Turn LT L" (see fig. 5B). Accordingly, the left turn signal lamp V1 is turned off (see fig. 5E).
That is, in the example shown in fig. 5, the control unit 13 continues to generate the left-turning steering signal "Turn LT L" until the predetermined condition described above is satisfied (until time t 33).
Next, at time t34, the driver of the vehicle V who wants to generate the right-Turn steering signal (for example, the maximum steering signal) "Turn LT R" (see fig. 5 (B)) moves the operation unit 11 from the neutral position 11A to the second position 11C. That is, the driver performs, for example, the maximum steering operation for the right turn. Accordingly, the switch unit 12 starts outputting the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 (see fig. 5C).
On the other hand, the control unit 13 has not yet started generating the steering signal "Turn LT R" for right turning according to the second position 11C of the operation unit 11 (see fig. 5 (D)). Therefore, the right turn signal lamp V2 has not yet started flashing (see fig. 5F). The right side lateral lamp V4 is not yet turned on (see fig. 5G).
When the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V at time t34, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A starts blinking display (see fig. 5H). On the other hand, even when the camera 14B of the detection unit 14 captures an image of another vehicle present on the right rear side of the vehicle V, the auditory attention notifying unit 15B does not start outputting the warning sound (see fig. 5 (I)).
At time t34, display unit 15A4 of visual attention notifying unit 15A starts displaying an image of the right rear side situation of vehicle V captured by camera 14B of detection unit 14 (see fig. 5 (J)).
Next, determination unit 13A of control unit 13 determines whether or not switch unit 12 continues to output ON signal "Turn SW R ON" corresponding to second position 11C of operation unit 11 in determination period DP3 (time t35 to time t36) which is a period after time point (time t35) when set period SP4 (time t33 to time t35) elapses from the end time point (time t33) of determination period DP1 (time t31 to time t33) (see fig. 5 (C)). Specifically, the determination unit 13A determines that the switch unit 12 continues to output the ON signal "Turn SW R ON" in the determination period DP3 (see fig. 5C). As a result, at time t35, the control unit 13 starts generating the right-Turn steering signal "Turn LT R" corresponding to the second position 11C of the operation unit 11 (see fig. 5D). Accordingly, the right turn signal lamp V2 starts to blink (see fig. 5F). The right side lateral lamp V4 is turned on (see fig. 5G).
At time t35, the auditory attention notifying unit 15B starts outputting a warning sound (see fig. 5 (I)).
The blinking display of the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A is continued (see fig. 5 (H)), and the display unit 15A4 of the visual attention notifying unit 15A continues the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 5 (J)).
In another example, the timing at which the right side illumination lamp V4 is turned on and/or the timing at which the auditory attention notifying unit 15B starts outputting the warning sound may be different from the time t35 by a time lag, for example.
In the example shown in fig. 5, next, at time t36, operation unit 11 is reset to neutral position 11A.
Accordingly, the output from the switch unit 12 is switched from the ON signal "Turn SW R ON" to the OFF signal "Turn SW R OFF" (see fig. 5 (C)). Accordingly, the control unit 13 does not generate the right Turn steering signal "Turn LT R" (see fig. 5D). Accordingly, the right turn signal lamp V2 is turned off (see fig. 5F). The right side lateral lamp V4 is also turned off (see fig. 5G).
At time t36, the display unit 15A2 or the display unit 15A3 of the visual attention notifying unit 15A terminates the blinking display (see fig. 5H), and the auditory attention notifying unit 15B terminates the output of the warning sound (see fig. 5I).
At time t36, the display unit 15A4 of the visual attention notifying unit 15A ends the display of the image of the right rear side situation of the vehicle V captured by the camera 14B of the detection unit 14 (see fig. 5J).
That is, in the example shown in fig. 5, when the switch unit 12 outputs the ON signal "Turn SW R ON" (see fig. 5 (C)) corresponding to the second position 11C of the operation unit 11 after the control unit 13 generates the Turn signal "Turn LT L" (see fig. 5 (B)) for left-turning corresponding to the first position 11B of the operation unit 11 in the determination period DP1 (time t31 to time t33), the determination unit 13A determines whether or not the switch unit 12 continues to output the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11 in the determination period DP3 which is a period after the time (time t35) of the setting period SP4 (time t33 to time t35) elapses from the end time (time t33) of the
In the example shown in fig. 5, during the determination period DP3, the switch unit 12 continues to output the ON signal "Turn SW R ON" corresponding to the second position 11C of the operation unit 11, and therefore, at time t35, the control unit 13 starts generating the right-turning steering signal "Turn LT R" corresponding to the second position 11C of the operation unit 11.
When the switch unit 12 continues to output the ON signal "Turn SW R ON" (see fig. 5C) during the determination period DP3 (after time t35), that is, when the output of the ON signal "Turn SW R ON" is generated after the elapse of the set period SP4 (time t33 to time t35), it can be estimated that the driver of the vehicle V wants to generate the right-Turn steering signal "Turn LT R" (see fig. 5D) instead of the operation unit 11 being located at the second position 11C by the erroneous operation of the driver of the vehicle V.
Therefore, in the example shown in fig. 5, as described above, when the switch unit 12 continues to output the ON signal "Turn SW R ON" in the determination period DP3, that is, when the ON signal "Turn SW R ON" is output after the set period SP4 (time t33 to time t35) elapses, the control unit 13 generates the right Turn steering signal "Turn LT R". Therefore, the request of the driver of the vehicle V who wants to generate the right Turn steering signal "Turn LT R" can be satisfied.
In the example shown in fig. 5, when the switch unit 12 continues to output the ON signal "Turn SW R ON" in the determination period DP3, that is, when the output of the ON signal "Turn SWR ON" is generated after the set period SP4 (time t33 to time t35) has elapsed, the auditory attention notifying unit 15B performs auditory attention notifying based ON the output "Turn SW R ON" of the ON signal corresponding to the second position 11C of the operation unit 11 (see fig. 5C) and the detection result of the camera 14B of the detection unit 14 (the image of another vehicle present ON the right rear side of the vehicle V).
Therefore, safety can be improved as compared with a case where the attention calling is not performed by the attention calling part 15.
In the example shown in fig. 5, the tactile attention notifying unit 15C does not perform the tactile attention notifying at time t35, but in another example, the tactile attention notifying unit 15C may perform the tactile attention notifying at time t 35.
In the example shown in fig. 5, when the switch unit 12 continues to output the ON signal "Turn SW R ON" in the determination period DP3, that is, when the ON signal "Turn SWR ON" is output after the set period SP4 (time t33 to time t35) has elapsed, the control unit 13 generates a signal for operating the right side lamp V4 in accordance with the right Turn signal "Turn LT R" (see fig. 5 (D)), and accordingly, the right side lamp V4 is turned ON.
Therefore, safety can be improved as compared with the case where the right side lamp V4 is not turned on at time t 35.
In the example shown in fig. 5, the driver moves the operation unit 11 to the second position 11C only once at time t34, but in another example, the driver moves the operation unit 11 twice during the set period SP4 (time t33 to time t 35). Specifically, after the operation unit 11 is reset to the neutral position 11A in the setting period SP4, the operation unit 11 is operated to the second position 11C again. As a result, in this example, the control unit 13 generates the right Turn steering signal "Turn LT R" before the set period SP4 passes (before the time t 35). Further, before the set period SP4 elapses (before the time t35), when the camera 14B of the detection unit 14 captures an image of another vehicle present ON the right rear side of the vehicle V, the auditory attention notifying unit 15B starts outputting the warning sound based ON the output of the ON signal "Turn SW R ON".
The determination period DP1, the determination period DP2, the determination period DP3, the setting period SP1, the setting period SP2, the setting period SP3, and/or the setting period SP4 can be changed by setting. In other examples, these values may be changed in accordance with parameters such as vehicle speed.
In the above example, the lane change signal and the maximum turn signal are not separated, but in another example, as in the technique described in japanese patent application laid-open No. 2016-43805, for example, the lane change signal and the maximum turn signal may be separated.
In the blind spot information function of the above example, the control of turning on the lamp is not performed when another vehicle is present in the blind spot of the driver, but in another example, the control of turning on the lamp may be performed when another vehicle is present in the blind spot of the driver in the blind spot information function.
In the blind spot information function of the above example, the control of blinking the lamp is not performed when the driver operates the steering lever of the operation unit 11, but in another example, the control of blinking the lamp may be performed when the driver operates the steering lever of the operation unit 11 in the blind spot information function.
In the above example, the blind spot information function is not turned off by customization, but in other examples, the blind spot information function may be turned off by customization.
Fig. 6 is a flowchart for explaining an example of processing executed in the vehicle driving
In the example shown in fig. 6, in step S1, for example, control unit 13 determines whether or not output of the on signal from switch unit 12 is started. When the output of the on signal from the switch unit 12 is started, the process proceeds to step S2. On the other hand, if the output of the on signal from the switch unit 12 is not started, the processing shown in fig. 6 is ended.
In step S2, the control unit 13 starts generating a steering signal. Specifically, in step S2, blinking of the turn signal lamp is started, and the visual attention notifying unit 15A and the auditory attention notifying unit 15B start attention notifying based on the detection result of the detecting unit 14, and the side illumination lamp starts to be turned on.
Next, in step S3, the determination unit 13A determines whether or not the determination period DP1 is equal to or greater than the
In step S4, the control unit 13 generates a maximum steering signal.
Next, in step S5, for example, the control unit 13 determines whether or not the output from the switch unit 12 is switched from the on signal to the off signal. When the output from the switch unit 12 is switched from the on signal to the off signal, the process proceeds to step S6. On the other hand, when the output from the switch unit 12 is not switched from the on signal to the off signal, step S5 is repeated.
In step S6, the blinking of the turn signal lamp ends. When the visual attention calling part 15A and the auditory attention calling part 15B perform the attention calling in step S6, the visual attention calling part 15A and the auditory attention calling part 15B stop the attention calling. When the front side illumination lamp is turned on in step S6, the side illumination lamp is turned off.
Next, in step S7, for example, the control unit 13 determines whether or not the output of the on signal in the opposite direction from the switch unit 12 is started within a predetermined time. When the on signal in the opposite direction is output from the switch unit 12 within the predetermined time, the process proceeds to step S8. On the other hand, if the output of the on signal in the opposite direction from the switch unit 12 is not started within the predetermined time, the processing shown in fig. 6 is ended.
In step S8, only the visual attention calling part 15A starts the attention calling based on the detection result of the detecting part 14.
Next, in step S9, for example, control unit 13 determines whether switch unit 12 continues to output an on signal in the opposite direction in determination period DP3 after the set period SP4 has elapsed, or whether the driver has moved operation unit 11 twice in set period SP 4. When the switch unit 12 continues to output the on signal in the reverse direction in the determination period DP3 after the set period SP4 has elapsed, or when the driver moves the operation unit 11 twice in the set period SP4, the process proceeds to step S10. On the other hand, when the switch unit 12 does not output the on signal in the reverse direction in the determination period DP3 after the set period SP4 has elapsed and the driver does not move the operation unit 11 twice in the set period SP4, the processing shown in fig. 6 is ended.
In step S10, the blinking of the blinker light in the opposite direction is started, and the auditory attention notifying unit 15B starts the attention notifying based on the detection result of the detecting unit 14, and the side illumination light in the opposite direction starts to be turned on.
In step S11, the control unit 13 generates a one-touch turn signal, and blinks the turn signal lamp only three times. During the blinking of the turn signal, the visual attention notifying unit 15A and the auditory attention notifying unit 15B notify attention based on the detection result of the detecting unit 14, and the side illumination lamp is turned on.
Next, in step S12, for example, the control unit 13 determines whether or not the output of the on signal in the opposite direction from the switch unit 12 is started during or within a predetermined time after the blinking of the turn signal. When the on signal output in the reverse direction from the switch unit 12 is started, the process proceeds to step S13. On the other hand, if the output of the on signal in the opposite direction from the switch unit 12 is not started, the processing shown in fig. 6 is ended.
In step S13, only the visual attention calling part 15A starts the attention calling based on the detection result of the detecting part 14.
Next, in step S14, for example, control unit 13 determines whether switch unit 12 continues to output an on signal in the opposite direction in determination period DP2 after the set period SP3 has elapsed, or whether the driver has moved operation unit 11 twice in set period SP 3. When the switch unit 12 continues to output the on signal in the reverse direction in the determination period DP2 after the set period SP3 has elapsed, or when the driver moves the operation unit 11 twice in the set period SP3, the process proceeds to step S15. On the other hand, when the switch unit 12 does not output the on signal in the reverse direction in the determination period DP2 after the set period SP3 has elapsed and the driver does not move the operation unit 11 twice in the set period SP3, the processing shown in fig. 6 is ended.
In step S15, the blinking of the blinker light in the opposite direction is started, and the auditory attention notifying unit 15B starts the attention notifying based on the detection result of the detecting unit 14, and the side illumination light in the opposite direction starts to be turned on.
Fig. 7 is a flowchart for explaining an example of processing executed in the vehicle driving
In the example shown in fig. 7, in step S21, for example, the control unit 13 determines whether or not the switch unit 12 has started outputting the on signal for one-touch steering. When the switch unit 12 starts outputting the on signal for the one-touch steering, the process proceeds to step S22. On the other hand, if the switch unit 12 does not start outputting the on signal for one-touch steering, the processing shown in fig. 7 is ended.
In step S22, for example, the control unit 13 determines whether the switch unit 12 has output a lane change signal. When the switch unit 12 outputs the lane change signal, the process proceeds to step S23. On the other hand, if the switch unit 12 does not output the lane change signal, the process proceeds to step S29.
In step S23, the control unit 13 generates a maximum steering signal. Specifically, in step S23, the winker blinks, and based on the detection result of the detection unit 14, the visual attention notifying unit 15A and the auditory attention notifying unit 15B notify attention, and the side illumination lamp is turned on.
Next, in step S24, for example, the control unit 13 determines whether or not the automatic cancellation condition is satisfied. When the automatic cancellation condition is satisfied, the blinking of the turn signal lamp is ended. When the visual attention calling part 15A and the auditory attention calling part 15B perform the attention calling in step S24, the visual attention calling part 15A and the auditory attention calling part 15B stop the attention calling. When the front side illumination lamp is turned on in step S24, the side illumination lamp is turned off. Next, the process proceeds to step S25. On the other hand, if the automatic cancellation condition is not satisfied, step S24 is repeated.
In step S25, for example, the control unit 13 determines whether or not the output of the on signal in the opposite direction from the switch unit 12 is started within a predetermined time. When the on signal in the opposite direction is output from the switch unit 12 within the predetermined time, the process proceeds to step S26. On the other hand, if the output of the on signal in the opposite direction from the switch unit 12 is not started within the predetermined time, the processing shown in fig. 7 is ended.
In step S26, only the visual attention calling part 15A starts the attention calling based on the detection result of the detecting part 14.
Next, in step S27, for example, control unit 13 determines whether or not switch unit 12 continues to output an on signal in the opposite direction in determination period DP3 after the set period SP4 has elapsed. When the switch unit 12 continues to output the on signal in the reverse direction in the determination period DP3 after the set period SP4 elapses, the process proceeds to step S28. On the other hand, when the on signal in the opposite direction is not output in the determination period DP3 after the set period SP4 has elapsed, the switch unit 12 ends the processing shown in fig. 7.
In step S28, the blinking of the blinker light in the opposite direction is started, and the auditory attention notifying unit 15B starts the attention notifying based on the detection result of the detecting unit 14, and the side illumination light in the opposite direction starts to be turned on.
In step S29, the control unit 13 generates a one-touch turn signal, and blinks the turn signal lamp only three times. During the blinking of the turn signal, the visual attention notifying unit 15A and the auditory attention notifying unit 15B notify attention based on the detection result of the detecting unit 14, and the side illumination lamp is turned on.
Next, in step S30, for example, the control unit 13 determines whether or not the output of the on signal in the opposite direction from the switch unit 12 is started during or within a predetermined time after the blinking of the turn signal. When the on signal output in the reverse direction from the switch unit 12 is started, the process proceeds to step S31. On the other hand, if the output of the on signal in the opposite direction from the switch unit 12 is not started, the processing shown in fig. 7 is ended.
In step S31, only the visual attention calling part 15A starts the attention calling based on the detection result of the detecting part 14.
Next, in step S32, for example, control unit 13 determines whether or not switch unit 12 continues to output an on signal in the opposite direction in determination period DP2 after the set period SP3 has elapsed. When the switch unit 12 continues to output the on signal in the reverse direction in the determination period DP2 after the set period SP3 elapses, the process proceeds to step S33. On the other hand, when the on signal in the opposite direction is not output in the determination period DP2 after the set period SP3 has elapsed, the switch unit 12 ends the processing shown in fig. 7.
In step S33, the blinking of the blinker light in the opposite direction is started, and the auditory attention notifying unit 15B starts the attention notifying based on the detection result of the detecting unit 14, and the side illumination light in the opposite direction starts to be turned on.
