Technical Field

The present invention relates to a shift device for switching a running range of a transmission mounted on an automobile, and more particularly to a shift device provided with a means for preventing a shift range of a display portion of the shift device from being inconsistent with a shift range of the automobile.

Background

Conventionally, there is known a shift device for an automobile, which is provided around a display panel provided in front of a driver or a vehicle driving operation steering wheel, and which can select a driving range by switching the shift position by a turning operation of a turning operation member. In addition, in the conventional shifting device, the position of the current shift position is displayed in accordance with the travel position selected by rotating the operating member.

Disclosure of Invention

[ problems to be solved by the invention ]

However, the appropriate gear is not always selected by the driver's desire to perform the shift of the gear. For example, when the driver stops at a shift position other than the P (park) range and gets off the vehicle, the selection of the shift position is not appropriate. The following control methods are known: when the driver parks in a gear position other than the P range, the shift is automatically made to the P range. In this way, when the vehicle automatically switches the shift range of the transmission to a range different from the range position selected by the driver by turning the turning operation member of the shifting device, the display unit of the shifting device needs to display the shift range according to the range position actually selected by the vehicle (transmission).

In both cases, if the control device of the display unit for displaying the shift position in the shifting device instructs the shift position displayed on the display unit of the shifting device to switch the shift position of the vehicle (transmission), and instructs the vehicle (transmission) to switch the shift position, the shift position displayed on the display unit of the shifting device and the shift position switched by the vehicle (transmission) are instructed by the other control device, there is a possibility that the shift position displayed on the display unit of the shifting device and the shift position switched by the vehicle (transmission) do not match each other, and the driver may erroneously recognize the actual shift position of the vehicle.

The present invention has been made to solve the problems of the conventional techniques, and an object of the present invention is to provide: even when the driver rotationally operates the shift position selected by the rotationally operating member of the shifting device, which is different from the actual selected shift position of the vehicle (transmission), the displayed shift position coincides with the actual vehicle shift position, so that the driver can correctly know the actual vehicle shift position.

[ means for solving problems ]

In order to solve the above problem, the present invention provides a shift device for a vehicle, including: a shift member that can be switched to a specific shift among a plurality of shift positions by rotating a dial operation member; 1 st control means for causing the display means to display the shift position if the shift position is switched to the specific shift position; and a 2 nd control means for switching a shift position of the vehicle in accordance with an operation of the shift member; the shifting device is characterized in that: the display means may display a shift position that is not affected by a rotational operation of the shift member, and the shift position of the vehicle may be switched to a shift position that is not affected by a rotational operation of the shift member, and the instruction to switch the shift position of the vehicle and the instruction to the display means may be executed by one of the 1 st control means and the 2 nd control means.

According to this configuration, even when the vehicle is automatically switched between the shift positions without being affected by the shift member being turned by the driver, the instruction to display the display means and the instruction to switch between the shift positions of the vehicle are executed by the same control means, and therefore, the two instructions do not coincide with each other. Therefore, the driver can correctly know the actual vehicle gear.

In this case, the present invention is characterized in that when the present vehicle shift position is different from the indication of the shift position on the display means, the indication of the present vehicle shift position on the display means is performed, and when the operating member is located between the positions of specific shift positions among the plurality of shift positions, the indication of the present vehicle shift position is prohibited.

According to this configuration, the driver can accurately know the actual current vehicle shift position by displaying the shift position corresponding to the current vehicle shift position on the display member. Further, when the operating member is located between the positions of the specific shift position among the plurality of shift positions, it is not determined which shift position the driver wants to select, and therefore, the display of the shift position corresponding to the shift position of the vehicle on the display member is prohibited at this time.

In this case, the present invention is characterized by including an automatic parking range switching control for switching the shift range of the vehicle to the parking range when the power supply (IG) of the vehicle is turned off in a state where the specific shift range is a shift range other than the parking range; when it is determined that the parking range is switched, the display means is instructed to display the position of the parking range, and the display is prohibited until it is determined that the parking range is switched.

According to this configuration, when it is determined that the vehicle range is switched to the parking range during the automatic parking range switching control, the display on the display member is changed to the parking range position, and therefore the position of the vehicle range matches the range position displayed on the display member. Further, the driver can accurately know the time when the vehicle shift position is automatically switched by prohibiting the display change on the display member until it is determined that the vehicle shift position has been switched to the parking position.

In this case, the present invention is characterized by including an automatic parking control for performing a parking operation by automatically switching the vehicle range to a driving range or a reverse range, and when the operating member is operated during the automatic parking control, the automatic parking control is prohibited and switching of display on the display unit is also prohibited.

According to this structure, when there is an operation of shift position switching by the driver during automatic parking control, the position of the current vehicle shift position may not coincide with the shift position displayed by the display member. At this time, the automatic parking control is prohibited, and the display switching on the display member is also prohibited, whereby the inconsistency between the position of the current vehicle shift position and the shift position displayed by the display member can be suppressed.

(Effect of the invention)

As described above, according to the present invention, even when the position of the shift position operated by the driver is different from the position of the current vehicle shift position, the occurrence of the discrepancy between the shift position displayed on the display device and the position of the current vehicle shift position can be suppressed, and the driver can be prevented from misunderstanding the current vehicle shift position.

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 portion 2, a 1 st control means 31, and a 2 nd control means 32. The shift position selecting member 1 is a member that selects a shift position of a transmission 4 of the vehicle V. As shown in fig. 1 and 2, the shift member 1 is disposed on the display panel 5 in front of the driver 6 and on the lower left of the vehicle travel operation wheel 8. A display portion 2 is disposed above the shift member 1. The vehicle V is also provided with a control device 3, and the control device 3 includes a 1 st control means 31 for controlling the display unit 2 and a 2 nd control means 32 for controlling a vehicle shift position switching device 41 of the transmission 4. Further, a power switch 7 of the vehicle is disposed on the lower left side behind the vehicle travel operation steering wheel 8. The transmission 4 can be shifted by an electric motor of an electric vehicle.

Fig. 3 is a block diagram of a system showing a control path of the shifting device S. The 1 st control means 31 receives a signal from the shift position changing member 1 (operating member) and controls the display of the shift position on the display portion 2 of the shift position changing device S. The 2 nd control means 32 receives a signal from the shift position changing member 1 (operating member) and controls the shift position change by the vehicle shift position changing device 41 of the transmission 4. The 1 st control means 31 controls the display of the shift position by the display portion 2 in accordance with the shift position switched when the 2 nd control means switches the shift position by the vehicle shift position switching device 41. The signal from the power switch 7 may also affect the control of the 2 nd control means. As described below, the 2 nd control means may be used to control the shift display on the display unit 2 instead of the 1 st control means. When the 2 nd control means cannot recognize the shift position of the vehicle shift position switching device 41, for example, immediately after the power switch 7 is turned on from off or immediately after the power supply of the vehicle is turned on from off, the 1 st control means controls the switching of the vehicle shift position switching device 41 in accordance with the shift position displayed on the display unit 2.

As shown in fig. 4, the shift member 1 includes a dial type rotation operation member having a 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. As described below, the display unit 2 may display not only the position of the shift position selected by the operation of the shift position member 1 but also the actual shift position of the vehicle switched by the vehicle shift position switching device 41.

The shift position switched by the vehicle shift position switching device 41 and the shift position displayed on the display unit 2 include a P (parking) range when the vehicle is parked, a R (reverse) range in which the vehicle is caused to travel backward, an N (neutral) range in which the transmission of the driving force is blocked, and a D (forward) range in which the vehicle is caused to travel forward, as well as an L (low speed (1 speed)) range, a 2(2 speed) 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 positions on the display unit 2, which indicate the shift positions, are arranged in the order of P, R, N, D, S from the left side.

The vehicle shift device S of the present invention can switch to a shift position that is not affected by the rotational operation of the shift member 1 in the vehicle shift position switching device 41 of the transmission 4 when the driver 6 selects an inappropriate shift position or the like, and can display the shift position that is not affected by the rotational operation of the shift member 1 on the display portion 2.

For example, when the driver 6 turns off the vehicle power supply and gets off the vehicle V in a state where the driver 6 selects a shift position other than the parking range (P) using the shift unit 1 after the vehicle V is parked, the shift position selected by the driver 6 is not appropriate. In this case, the shift device S of the present invention is configured to automatically switch the shift position of the vehicle to the parking range (P) by controlling the vehicle shift position switching device 41 by the 2 nd control means 32.

When the vehicle shift position is automatically switched in this manner, if the display position of the display unit 2 is kept the original shift position, the actual vehicle shift position does not coincide with the shift position displayed on the display unit 2, and the driver 6 cannot know that the actual vehicle shift position has been switched to the parking position (P) by the vehicle shift position switching device 41. Therefore, in this case, in the shifting device S of the present invention, the display position of the display unit 2 is controlled not in accordance with the instruction (reception of the signal) from the 1 st control means 31 but in accordance with the instruction (reception of the signal) from the 2 nd control means 32, so that the display position of the display unit 2 can be matched with the actual shift position of the vehicle. In the above case, the shift position displayed on the display unit 2 is set to the parking range (P) in accordance with the instruction from the 2 nd control means 32 for recognizing that the actual shift position of the vehicle is the parking range (P).

In addition, as an example in which the operation of the shift position by the driver 6 is not appropriate, when the shift member 1 is positioned between specific gears due to the driver 6 operating the shift member 1, it is unclear which gear the driver 6 wants to select. Therefore, at this time, it is prohibited to match the display position of the display unit 2 with the actual gear position of the vehicle.

Next, referring to the flowchart of fig. 5, the control when the displayed shift position displayed on display unit 2 of shift device S is different from the actual vehicle shift position switched by vehicle shift position switching device 41 will be described.

As shown in fig. 5, first, the driver 6 selects a shift position by turning the shift member (step ST 11). At this time, the display of the shift position on the display unit 2 of the shifting device S is controlled by the 1 ST control means 31, and the switching of the vehicle shift position by the vehicle shift position switching device 41 is controlled by the 2 nd control means 32 (step ST 12).

Next, the 1 ST control means 31 judges whether or not the position of the shift position changing member 1 of the shifting device S is located between the positions of the specific shift positions (step ST 13). If yes, i.e., if the position of the shift position changing member 1 of the shifting device S is located between the positions of the specific gear positions, the process proceeds to step ST 14; if "no", that is, if the position of the shift position changing member 1 of the shifting device S is determined to be any one of the specific shift positions, the process proceeds to step ST 15.

At step ST14, when the position of the shift position changing member 1 of the shifting device S is located between the positions of the specific gear positions, it is uncertain which gear position the driver 6 wants to select, and therefore the display of the actual gear position of the vehicle gear position on the display portion 2 of the shifting device S is prohibited (step ST 14). And then returns to step ST 11. Thereafter, the turning operation of the shift position member 1 is resumed, and as long as no is obtained in step ST13, that is, as long as the position of the shift position member 1 of the shift position device S is not determined to be the position of any particular shift position, the control for prohibiting the display of the actual shift position of the vehicle shift position on the display portion 2 of the shift position device S is continued.

On the other hand, since the position of the shift position member 1 of the shift device S is determined to be any specific shift position in step 15, the shift position selected by the driver 6 operating the shift position member 1 is displayed on the display unit 2 of the shift device S by the 1 ST control means 31 (step ST 15).

Next, the 2 nd control means 32 determines whether or not the vehicle shift position is automatically switched by the vehicle shift position switching device 41 (step ST 16). If yes, that is, if the vehicle shift position is automatically switched by the vehicle shift position switching device 41, the process proceeds to step ST 17; if no, that is, if the vehicle range is not automatically switched by the vehicle range switching device 41, the process returns to step ST 12.

If step ST16 is no, the process returns to step ST12, and after the control of controlling the display of the shift position on display unit 2 of shift device S by first control means 31 and the control of controlling the switching of the vehicle shift position by vehicle shift position switching device 41 by second control means 32 are continued, it is determined again in step ST16 whether or not the automatic switching of the vehicle shift position is performed by vehicle shift position switching device 41, and if the determination result is not yes, the cycle of moving in the order of step ST12, step ST13, step ST15, step ST16, and step ST12 is repeated, and the display unit 2 of shift device S continues to display the shift position selected by driver 6 operating shift position switching device 1.

Next, when it is determined as yes in step ST16, that is, when it is determined that the automatic switching of the vehicle shift position is completed, it is determined whether or not the shift position displayed on the display unit 2 of the shift device S matches the position of the vehicle shift position selected by switching with the vehicle shift position switching device 41 (step ST 17). If the determination result is yes, that is, if the shift position displayed on the display unit 2 of the shifting device S matches the position of the vehicle shift position selected by switching with the vehicle shift position switching device 41, the process returns to step ST15, and the control for displaying the position of the shift position selected by the driver 6 operating the shift member 1 on the display unit 2 of the shifting device S is continued. When the judgment result is 'no'. That is, the position of the shift range displayed on the display unit 2 of the shifting device S is different from the position of the vehicle shift range selected by switching with the vehicle shift range switching device 41, the process proceeds to step ST 18.

In step ST18, the result of the determination in step ST17 that the shift position displayed on the display unit 2 of the gearshift device S is different from the position of the vehicle shift position selected by the switching of the vehicle shift position switching device 41 is received, and the switching to the switching control of the vehicle shift position by the vehicle shift position switching device 41 and the display control of the display unit 2 of the gearshift device S are controlled by the 2 nd control means 32. Thereby, the shift position displayed on the display unit 2 of the shift device S can be matched with the position of the vehicle shift position selected by switching by the vehicle shift position switching device 41 (step ST 18).

Next, with reference to the flowchart of fig. 6, the control when the power supply of the vehicle is turned off after the vehicle shift position is set to a shift position other than the parking position (P) will be described.

As shown in fig. 6, first, when the vehicle power supply is turned from on to off by the operation of the vehicle power switch 7 (step ST21), it is determined whether or not the vehicle shift position is changed to the parking position (P) (step ST 22). If the determination result is "yes", that is, as long as the vehicle gear at the time of turning off the power of the vehicle is changed to the parking gear (P), there is no problem, and therefore there is no need to take any special measures, and the flow ends. If the determination result is "no", that is, if the vehicle shift position is changed to the vehicle shift position other than the parking position (P) when the vehicle power is turned off, the process proceeds to step ST 23.

In step ST23, the vehicle shift position switching device 41 is instructed to switch the vehicle shift position, and the vehicle shift position is set to the parking position (P). At this time, the display unit 2 of the shift device S prohibits the change of the display range (step ST23) until the determination result that the vehicle range is changed to the parking range (P) is received.

Then, it is determined again whether or not the vehicle speed has changed to the parking range (P) (step ST 24). If the determination result is "yes", that is, if it is confirmed that the vehicle shift position is actually changed to the parking position (P) after the instruction to change the vehicle shift position to the parking position is issued, the process proceeds to step ST25, the display unit 2 of the shift device S is switched to the parking position (P) (step ST25), and the control flow is ended.

On the other hand, if the determination result at step ST24 is "no", that is, if it is not possible to confirm whether or not the vehicle shift position has actually changed to the park position (P) after the instruction to change the vehicle shift position to the park position is issued, the process returns to step ST 23. Then, again at step ST24, it is determined whether or not the vehicle position has changed to the park position (P), and as long as it is not confirmed that the vehicle position has changed to the park position (P), the cycle of moving in the order of step ST23, step ST24, and step ST23 is repeated. By this, can avoid when the vehicle gear changes to the parking gear, show the gear and show the gear different with actual vehicle gear.

Next, as another embodiment of the present invention, an example of the following case is described: when the control of switching the vehicle shift position is performed by the vehicle shift position switching device 41 of the transmission 4 and the control of automatically switching the vehicle shift position to the running position (D) and the reverse position (R) and performing the parking operation is performed by the 2 nd control means 32 of the shifting device S, the driver 6 performs the operation of switching the vehicle shift position by the shifting member 1 of the shifting device S. In automatic parking control for automatically switching the vehicle shift position to the drive position (D) and the reverse position (R) to perform a parking operation, the display unit 2 of the shift device S also switches and displays the drive position (D) and the reverse position (R) in accordance with the actual vehicle shift position that is automatically switched.

During the automatic parking control, when the driver 6 operates the shift member (operation member) 1 of the shift device S, the automatic parking control is stopped, and at this time, the display portion 2 of the shift device S during the automatic parking control also prohibits the switching display with respect to the display control of the switching of the running range (D) and the reverse range (R). This can prevent the current actual vehicle gear position from being inconsistent with the gear position displayed on the display unit 2 of the shifting device S.

Next, referring to the flowchart of fig. 7, the flow of control performed when the driver 6 operates the shift member (operation member) 1 of the shift device S during the automatic parking control will be described.

As shown in fig. 7, first, the automatic parking control operation is completed, that is, the vehicle gear position switching device 41 switches the actual vehicle gear position to the driving gear position (D) and the reverse gear position (R) by the 2 nd control means 32 of the gearshift device S to automatically park the vehicle. During this automatic parking control, the display unit 2 of the shift device S also switches between the drive range (D) and the reverse range (R) in accordance with the actual vehicle shift position and displays the switch (step ST 31).

At an appropriate timing during the automatic parking control, it is determined whether the automatic parking control is ended (step ST 32). If the judgment result is yes, that is, when the automatic parking control is finished, no special measures need to be taken, and the process is finished. If the determination result is "no", that is, if the automatic parking control is not ended, the process proceeds to step ST 33.

In step ST33, it is determined whether or not the driver 6 has operated the shift member (operation member) 1 of the shift device S (step ST 33). If the determination result is yes, that is, if the driver 6 operates the shift member (operation member) 1 of the shifting device during the automatic parking control, the process proceeds to step ST 34. On the other hand, if the determination result is "no", that is, if the driver 6 does not operate the shift member (operation member) 1 of the shift device, the process returns to step ST 32. Then, in step ST32, if it is not determined yes again, that is, if the automatic parking control is not ended, the cycle of moving in the order of step ST32, step ST33, and step ST32 is repeated, and the automatic parking control is waited for to be ended, or the driver 6 operates the shift unit 1.

In step ST34, the automatic parking control is stopped, that is, the control for automatic parking is stopped by the 2 nd control means 32 of the gearshift device S by switching the actual vehicle shift position to the drive position (D) and the reverse position (R) by the vehicle shift position switching device 41, and at this time, the display switching on the display unit 2 of the gearshift device S is also prohibited (step ST 34). This makes it possible to avoid the actual vehicle shift position from being inconsistent with the shift position displayed on the display portion 2 of the shifting device S when the driver 6 operates the shifting member 1 of the shifting device S during the automatic parking control.

Next, during the automatic parking control, after the driver 6 has operated to end the automatic parking control, the ordinary parking operation or vehicle running operation is performed by the driver 6 operating the shift member 1 of the shift device S to switch the vehicle shift position (step ST35), and the control flow ends.

While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and can be implemented in various forms without departing from the scope of the present invention.
