Technical Field

The present invention relates to a shift device for switching a drive range of a transmission mounted on an automobile, and more particularly to a shift device capable of applying a reaction force for restricting an operation of a driver.

Background

Conventionally, a shift device is known which is provided in a vehicle around a display panel provided in front of a driver or a vehicle driving operation steering wheel and which can switch and select a driving range by a turning operation of a turning operation member. In addition, in the conventional shifting apparatus, the position of the current shift position is displayed according to the running position selected by rotating the operating member.

Patent document 1 describes a shifting device that limits the selection of a shift range that can be switched by a single operation by a driver, thereby preventing the driver from switching the shift range by mistake. In this way, it is designed to switch the shift range according to the intention of the driver.

Patent document 1: japanese patent laid-open publication No. 2013-47074

In addition, in the shift device of the rotation operation type, it is considered that an electric reaction force is applied to the rotation operation of the shift device in order to avoid the shift into a gear position other than the specific gear desired by the driver. The electric reaction force is applied after the driver continues to operate to some extent, so that the driver can recognize that the operation is limited. In addition, unnecessary power consumption is suppressed.

Disclosure of Invention

[ problems to be solved by the invention ]

However, when the driver feels a reaction force during the operation of the shift device, it is impossible to determine whether the reaction force is an appropriate reaction force for the operation of the driver or whether the necessary operation of the shift device is suspended by the driver or otherwise unnecessary operation is continued due to a failure of the structure of the shift device to which the reaction force is applied. Therefore, when the reaction force continues to be applied, there is a possibility that the shift position desired by the driver cannot be switched.

The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a shift device of a rotary operation type, in which, when an electric reaction force is applied to a rotary operation of the shift device in order to suppress entry into a shift position other than a specific shift position desired by a driver, the shift device cannot be switched to the shift position desired by the driver when the reaction force is continuously applied.

[ means for solving problems ]

In order to solve the above-described problems, the present invention provides a shift device for a vehicle, including a shift member that can be switched to a specific shift position among a plurality of shift positions by rotating a dial plate type operation member, the shift device comprising: the shift control device is provided with a reaction force application means for applying a reaction force when the shift member is rotationally operated and a reaction force application control means for controlling the application of the reaction force, wherein the reaction force application control means suppresses (including stopping and reducing) the application of the reaction force by the reaction force application means when the reaction force application means continues to apply the reaction force for a time exceeding a predetermined time.

When the application of the reaction force continues for a certain time, the driver cannot determine whether the reaction force is an appropriate reaction force for the operation of the driver or is due to a failure of the reaction force applying means. Further, when the reaction force applying means is malfunctioning, the driver may also want to switch the shift position, at which time the driver's operation intention is hindered. If the application of the reaction force is suppressed while the application of such reaction force continues for a certain time, it is possible to avoid hindering the operation of the driver.

In this case, the present invention is characterized in that the control of the application of the reaction force suppresses the application of the reaction force when the reaction force continues to be applied even if the notification means that operates after the lapse of the specific time continues to operate for a certain time.

Since the reaction force may be continuously applied by an erroneous operation of the driver, the notification means is activated to urge the driver to shift to the appropriate gear. Further, even if the reaction force application is continued after the notification means continues to operate for a certain time, the reaction force is suppressed at this time because the reaction force application means in the shift device is highly likely to malfunction.

In this case, the present invention is characterized in that after the reaction force application is suppressed, the reaction force continues to be suppressed until the shift to the specific gear is made.

There is also a possibility that the operating member of the shifting device is held at the intermediate position of the specific gear due to an erroneous operation by the driver or the like, and in such a case, an appropriate reaction force cannot be applied. The driver can switch the operating member of the shift device to the specific gear by suppressing the application of the reaction force, and therefore, after the application of the reaction force is suppressed, it is necessary to continue suppressing the reaction force until the shift to the specific gear.

In this case, in the present invention, the specific time is set so that the duration of the suppression of the reaction force generated during the switching from the parking range (P) to the other range is longer than the duration of the suppression of the reaction force generated during the switching from the driving range (D, R) to the other range.

When the vehicle is started when the vehicle is shifted from the parking range to another range, the reaction force during shifting from the parking range to another range is suppressed to be longer than the reaction force during suppressing the other range, thereby improving safety.

In this case, in the present invention, after the reaction force is suppressed, when the shift position is switched by the rotational operation, the shift position before the switching is set.

There is a possibility that a reaction force is applied by an erroneous operation of the driver, and the reaction force is suppressed, so that even if the erroneous operation continues the shift position switching, the shift position can be prevented from being switched carelessly in order to maintain the previous shift position.

(Effect of the invention)

As described above, the present invention relates to a swing operation type shift device that can be switched to a shift position desired by a driver when an electric reaction force is applied to a swing operation of the shift device in order to suppress entry into a shift position other than a specific shift position desired by the driver, and when the reaction force is continuously applied.

Detailed Description

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The shift device S of the vehicle V includes a shift member 1, a display unit 2 also serving as a notification means, a control device 3 including a reaction force application control means 31, a reaction force application means 4, and a timer 5 for measuring time. The shift component 1 is an operation component for the driver 6 to select a position of a shift range of a transmission of the vehicle V. As shown in fig. 1 and 2, the shift member 1 is disposed on a display panel 7 in front of a driver 6 and to the lower left of an operation wheel 8 for running the vehicle. Above the shift member 1, a display portion 2 serving as a notification means is disposed. Further, the vehicle V includes a reaction force applying means 4 and a control device 3, the reaction force applying means 4 applying a reaction force for operating the shift member 1 of the shift device S, and the control device 3 includes a reaction force application control means 31 controlling the reaction force applying means 4. The display unit 2 also serving as a notification means is controlled by the control device 3.

Fig. 3 is a block diagram of a system showing a control path in the shifting device S. The control device 3 (including the reaction force application control means 31) receives a signal for performing a rotational operation from the shift position member 1 (operating member), controls the reaction force application means 4 and gives an operation reaction force to the shift position member 1, and controls display of the shift position in the display portion 2 (notification means) of the shift device S. The control device 3 (including the reaction force application control means 31) receives information on the duration of the reaction force application by the reaction force application means 4 from the timer 5, receives information on the notification time from the display unit 2, and controls the reaction force application means 4 to perform measures such as suppression of the reaction force.

As shown in fig. 4, the shift member 1 includes a rotational operation member having a dial-type cylindrical knob member.

The display unit 2 is disposed above the shift member 1 and displays the position of the shift position selected by the operation of the shift member 1.

The shift position displayed on the display unit 2 includes a P (parking) range when the vehicle is parked, an R (reverse) range when the vehicle is driven backward, an N (neutral) range in which transmission of a driving force is blocked, and a D (drive) range when the vehicle is driven forward, as well as an L (low (1) range, a 2 (2) range, an S (sport mode) range, a B (regenerative braking) range, and the like. The shift device S of the present embodiment has P, R, N, D, S shift positions, and the display unit 2 displays the display positions of the shift positions in order of P, R, N, D, S from the left side.

As shown in fig. 2 and 4, the display unit 2 is provided with an alarm display unit 21 for displaying an abnormal state or the like on the lower right side of the position where the shift position is displayed (the right side of the display unit showing the S-shift position in the present invention). In the present invention, as described later, when the application time of the reaction force continues for a certain time or more, the corresponding place of the alarm display portion 21 blinks.

In the shifting device S of the vehicle of the present invention, when the driver 6 receives a reaction force in the turning operation of the shifting member 1, it is difficult for the driver 6 to determine whether the reaction force application control means 31 of the control device 3 controls the reaction force application means 4 to apply an appropriate reaction force to the shifting member 1 or whether the reaction force application means in the shifting device S is malfunctioning. Further, the driver 6 may want to perform the turning operation of the shift changing member 1 when the reaction force applying means 4 is out of order and receives a reaction force.

Therefore, when the driver 6 applies the reaction force to the shift change member 1 for a certain time or more in the operation of the shift change member 1, the notification means is activated, that is, the warning display portion 21 in the display portion 2 blinks accordingly, and the driver is notified that the application of the reaction force is still being applied after the certain time is exceeded. When the notification means is operated for a predetermined time or longer, that is, when the blinking of the alarm display unit 21 continues for a predetermined time, the reaction force application control means 31 controls the reaction force application means 4 to suppress the application of the reaction force.

When the reaction force is applied for a specific time or longer to the shift changing member 1, the notification means is operated because the reaction force is continuously applied, and there is a possibility that an erroneous operation by the driver 6 causes the notification means to be operated to cause the alarm display unit 21 to blink and display the corresponding portion, thereby urging the driver 6 to switch to the appropriate shift position.

The specific time until the reaction force is continuously applied to the operation of the notification means is longer than the duration of the reaction force generated during the switching from the drive range (D, R) to another range and the duration of the reaction force generated during the switching from the parking range (P) to another range.

This is because there is a possibility that the vehicle will start when the shift range is switched from the parking range (P) to another shift range, and it is desired to increase the time until the application of the reaction force is suppressed when the shift range is switched from the parking range (P) to another shift range, thereby improving safety.

Further, when the driver 6 performs an operation of selecting the shift position using the shift position member 1, there is a possibility that the operation of the shift position member 1 is maintained at the intermediate position of the shift position due to an erroneous operation or the like. At this time, an appropriate reaction force cannot be applied, and an unnecessary reaction force is applied. Therefore, even if the application of the reaction force is not immediately released (ended) after the application of the reaction force is suppressed, the application of the reaction force needs to be continuously suppressed until the driver 6 can switch the shift position by the operation of the shift position changing member 1.

Further, after the reaction force application is suppressed, when the shift position is switched due to the operation of the shift position changing member 1 by the driver 6, it is preferable to set the shift position before the switching. Thus, even when the shift position is switched while the erroneous operation is continued, the shift position is maintained in the previous shift position, and therefore, the erroneous shift position can be prevented. Further, the application of the reaction force is suppressed in the state in which the vehicle is in the park range position, and the vehicle can be prevented from starting by maintaining the park range even if the vehicle is switched from the park range by an erroneous operation or the like.

Next, a description will be given of a flow of controlling the suppression of the application of the reaction force when the reaction force is given to the rotational operation of the shift element 1 of the shift device S, with reference to the flowchart of fig. 5.

As shown in fig. 5, first, a reaction force is applied to the rotational operation of the shift change member 1 by the driver 6 for selecting the shift position (step ST1), and then the time for which the reaction force continues to be applied is measured by the timer 5 (T1) (step ST 2).

Next, it is determined whether or not the time (T1) for continuing the application of the reaction force measured in step ST2 is longer than the time (T01) (T1 ≧ T01? (step ST 3). When the result of the determination is yes, that is, when the time (T1) for continuing the application of the reaction force is longer than the predetermined time (T01), the process proceeds to the next step ST 4. When the determination result is "no", that is, when the time (T1) for continuing the application of the reaction force is short with respect to the time (T01), the process returns to step ST 2. At this time, the reaction force application time is measured again in step ST2 (T1), and then, until a yes result is obtained in step ST3, that is, until the reaction force application time (T1) is shorter than the predetermined time (T01), the same state is maintained by repeating the loop in the order of step ST2, step ST3, and step ST 2.

Although not shown in the flow of fig. 5, the specific time (T01) compared to the reaction force application time (T1) in step ST3 does not always take the same value in the operation of selecting (switching) which gear position, and for example, the specific time T02 when switching from the parking range (P) to another gear position is longer than the specific time T02 when switching from the driving range (D, R) to another gear position. When switching from the parking range to another range (driving range D, R, etc.), the vehicle may start, and in order to improve safety, it is prudent to wait for a long time before suppressing the application of the reaction force.

In the next step ST4, in the alarm display portion 21 in the display portion 2 of the shifting device S, the notification reaction force application time is displayed for a certain time to continue (step ST4), and the notification time (T2) is measured by the timer 5 (step ST 5).

Next, it is determined whether or not the notification time (T2) measured in step ST5 is longer than the predetermined time (T02) (T2 ≧ T02. If the determination result is yes, that is, if the notification time (T2) is longer than the predetermined time (T02), the process proceeds to the next step ST 7. If the determination result is "no", that is, if the notification time (T2) is shorter than the predetermined time (T02), the process returns to step ST 5. At this time, in step ST5, the reaction force application time is measured again (T2), and then, until a result of yes is obtained in step ST6, that is, the notification time (T2) is shorter than the predetermined time (T02), the cycle of steps ST5, ST6, and ST5 is repeated to continue the state of notification, and the driver 6 is urged to switch to the appropriate shift position.

In the next step ST7, the notification time is received (T2) and the specified time is continued (T02), and measures are taken to control the reaction force applying means 4 and suppress the reaction force (step ST 7). Then, it is determined whether or not the switching (selection) of the shift position by the shift position changing member 1 is completed with the application of the reaction force suppressed (step ST 8). When the determination result is yes, that is, when the switching of the shift position is ended, the process proceeds to the next step ST 9. When the determination result is "no", that is, when the switching of the shift position is not ended, the process returns to step ST 7. At this time, after the application of the reaction force is suppressed at step ST7, the cycle in the order of step ST7, step ST8 and step ST7 is repeated as long as the end of the switching of the shift position is not determined at step ST8, and the state where the reaction force is suppressed continues, while the driver 6 can perform the operation of switching the shift position by the operation of the shift position changing member 1.

In the next step ST9, the operation of the shift position changing member 1 by the driver 6 is received to end the switching of the shift position, and the suppression of the reaction force application is ended (step ST 9). Further, since the shift position may be switched by the continued erroneous operation of the driver 6, when the suppression reaction force application is ended upon receiving the end of the shift position switching by the driver 6 in order to avoid the careless shift position switching, the shift position before the switching is maintained after the suppression reaction force is received (step ST10), and the flow is ended.

While the present invention has been described above by way of examples, it is to be understood that the present invention is not limited to the examples, and various other modifications can be made without departing from the scope of the present invention.
