Abstract

PURPOSE:To prevent a shift lever from being undesirably disengaged from a state of its position regulation by making a disengaging action for the shift lever possible from the state of position regulation which is made by a shift lock mechanism for restricting the shift lever in a position to select P range. CONSTITUTION:When an ignition key-switch of a vehicle is turned off and an engine mounted on the vehicle is in a state of non-operation, a detected output signal Si from an ignition sensor 33 is not supplied to a control part 32, thereby a driving control signal Cr from the control part 32 to an actuator 31 also is not supplied. In this case, the upper end part 30A of an engaging pin lock member 30 connected to the actuator 31 is put in lock position. Furthermore, when the ignition key-switch of the vehicle is turned on and the engine mounted on the vehicle is in a state of operation, the detected output signal Si is supplied from the ignition sensor 33 to the control part 32.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for an automatic transmission that regulates the position of a shift lever operated to select a plurality of shift ranges in an automatic transmission depending on the situation.

0002

2. Description of the Related Art A plurality of shift ranges in an automatic transmission mounted on a vehicle are selected by operating a shift lever equipped with an engagement pin, and a position for selecting a desired shift range is selected. The shift lever is maintained in its position by engaging the locking mechanism with the engagement pin provided thereon. The locking mechanism is generally used for shift ranges selected by a shift lever, such as 2 range, 1 range, drive range (D range), neutral range (N range), reverse range (R range), and parking range (P range). ) and is provided with a detent member having a locking portion that is engaged with an engagement pin of a shift lever that assumes a position for selecting each shift range, and the detent member is The engagement pin is disengaged from the locking portion by a manually operated lock release button provided on the shift lever.

[0003] When a vehicle equipped with an automatic transmission is moved from a stopped state to a running state, the shift lever, which is normally supposed to select the P range of the automatic transmission, first shifts to the D range. Accordingly, the engagement pin provided on the shift lever changes from the state in which it is engaged with the engagement portion of the detent member corresponding to the P range to the engagement corresponding to the D range. The state is caused to shift to a state where it engages with the stop portion. In such a case, the shift lever that was supposed to select the P range will be operated to select the D range only with the clear will of the driver of the vehicle. In order to do this, the shift lever, which is in the position for selecting the P range, is allowed to shift to the position for selecting the D range only when a predetermined condition is satisfied, and the shift lever is made to be able to shift from the position for selecting the P range to the position for selecting the D range. It has been proposed to provide a shift lock mechanism in which a shift lever that is in a position for selecting the P range is restricted to a position for selecting the P range.

[0004] An example of such a shift lock mechanism is, for example, as shown in Japanese Utility Model Application No. 62-202433, which is formed by a lock plate provided with a through hole and attached to a shift lever, and a solenoid plunger. It consists of a lock pin and a control section. When such a shift lock mechanism is provided, the shift lever, which is provided with a locking pin that engages with the locking portion of the detent member and a lock release button for the locking pin, assumes a position for selecting the P range. When the brake system of the vehicle is not activated, the control unit causes the lock pin formed by the solenoid plunger to protrude and engage with the through hole of the lock plate, thereby, When the shift lever is in the restricted position where it is restricted to the position that selects the P range, and when the brake system is activated, the solenoid
The lock pin formed by the plunger is pulled in to release the engagement with the through hole of the lock plate, thereby not interfering with the transition of the shift lever from the P range selection position to the D range selection position. , an operation is performed to release the shift lever from the position restriction state. When the shift lever is released from the position restriction state, the lock release button provided on the shift lever is operated, the engagement pin is released from the locking part of the detent member, and then the shift lever is moved to the position The position is moved from the range selection position to the D range or R range selection position.

As mentioned above, if a predetermined condition such as activation of the vehicle's brake system is not satisfied, the shift lever that is supposed to select the P range cannot be moved to the position that selects the P range. For example, if a shift lock mechanism is provided that releases the position restriction state in which the P range is restricted only when a predetermined condition is satisfied in the position restriction state in which the P range is restricted, for example, the shift lock mechanism There is a risk that failures such as disconnection, short circuit, malfunction of the solenoid plunger, malfunction of circuit elements, etc. may occur in the lock pin formed by the solenoid plunger constituting the solenoid plunger or in the control section. If such a failure causes the lock pin formed by the solenoid plunger to become unable to disengage from being engaged with the through hole in the lock plate, the vehicle's brake system will be activated. Even if the predetermined conditions are satisfied, the shift lever will not be released from the position restriction state in which it is restricted to the position that selects the P range, and therefore the vehicle will not be able to shift from a stopped state to a running state. This causes the inconvenience of being recognized as such.

[0006] Therefore, the aforementioned
As disclosed in the above publication, the shift lever, which is placed in a position restricted state in which it is restricted to the position where the P range is selected by the shift lock mechanism, can be mechanically released from the position restricted state by manual operation. It has also been proposed to provide a shift lock release mechanism. Such a shift lock release mechanism is, for example,
In the case of the device disclosed in Japanese Patent No. 02433, a push button member that selectively engages with a lock pin formed by a solenoid plunger is provided, and when the push button member is operated, a solenoid constituting a shift lock mechanism is provided. - Mechanically moves the lock pin formed by the plunger to release it from the engagement state with the through hole of the lock plate, thereby removing the position restriction state in which the shift lever is restricted to the position where the P range is selected. Release shall be made manually.

[0007]

[Problems to be Solved by the Invention] However, in a vehicle equipped with an automatic transmission equipped with a shift lock mechanism and a shift lock release mechanism, it is normal for the shift lock mechanism to malfunction and cause the shift lock mechanism to is operated by the vehicle driver to release the shift lever from the position restriction state where the shift lever is restricted to the position where the P range is selected. In other words, the shift lock release mechanism provided for emergencies should be
The shift lever, which has been operated by mistake or against the driver's will and has been placed in the position restriction state where it is restricted to the position where the P range is selected by the normal operation of the shift lock mechanism, is in the P range position. There is a possibility that a situation may occur in which the user is undesirably released from the position restriction state where the user is restricted to the position where the range is selected. The possibility of such a situation occurring is undesirable, for example, not only from the standpoint of thoroughly preventing the vehicle from starting undesirably, but also from the standpoint of preventing theft of the vehicle.

In view of the above, the present invention provides a shift lever that is operated to select a plurality of shift ranges in an automatic transmission, and a shift lever that selects the P range, when predetermined conditions are met. If you are not satisfied,
A shift lock mechanism unit that releases the position restriction state in which the P range is selected only when a predetermined condition is satisfied in the position restriction state in which the P range is selected. and a shift lock release mechanism that releases the shift lever from the position restriction state by manual operation when the shift lever is placed in a position restriction state where it is restricted to a position where the P range is selected by the mechanism part,
If the shift lock release mechanism is operated without the vehicle driver's will, the shift lever, which has been placed in a position restricted state where it is restricted to the position where the P range is selected due to normal operation of the shift lock mechanism, is It is an object of the present invention to provide an operating device for an automatic transmission that can avoid a situation in which the position is undesirably released from the position regulation state.

[0009]

[Means for Solving the Problems] In order to achieve the above object, an automatic transmission operating device according to the present invention is operated to switch and select a plurality of shift ranges in an automatic transmission installed in a vehicle. A shift lever, a shift lever locking means having a locking portion corresponding to each of a plurality of shift ranges and engaged by the shift lever that takes a position for selecting each of the shift ranges, and a brake device of the vehicle is actuated. When the shift lever engaged with the locking part corresponding to the P range provided on the shift lever locking means is restrained and placed in a position restricted state, and the brake system of the vehicle is activated. , a shift lock mechanism section that releases the shift lever engaged with the locking section corresponding to the P range from a position restricted state; and a shift lock mechanism section that restrains the shift lever engaged with the locking section corresponding to the P range. Even if the shift lever is in the position restricted state, the shift lock release mechanism that releases the shift lever from the position restricted state by the shift lock mechanism and the key switch that controls the electrical system in the vehicle are connected to the key. Only when the shift lock release mechanism is in the operated state with the position of The key switch includes a shift lock/key lock control section that allows the key to be removed from the key switch only when the key switch is turned on.

0010

[Operation] In the automatic transmission operating device according to the present invention configured as described above, the shift lock release mechanism provided in association with the shift lock mechanism for the shift lever performs shift lock/key lock control. Only when the key is engaged with the key switch and the key switch is operated, the shift lock release mechanism section releases the shift lever from the shift lock mechanism. Furthermore, the shift lock/key lock control section allows the shift lever to be set to the P range by the shift lock/key lock control section.
Only when placed in a position restriction state in which the range is restricted to the range selection position is a state in which the key engaged with the key switch is allowed to disengage from the key switch. Therefore, the driver's action is to release the shift lever, which has been placed in a position restricted state where it is restricted to the position for selecting the P range by the shift lock mechanism, from the position restricted state by the shift lock release mechanism. The shift lock release mechanism was operated without the vehicle driver's will, and the shift lock release mechanism was restrained in the position where the P range is selected due to normal operation of the shift lock mechanism. A situation in which a shift lever placed in a position restricted state is undesirably released from the position restricted state is avoided. Furthermore, when the key is removed from the key switch and the driver leaves the vehicle, the shift lever is securely locked in the position for selecting the P range by the shift lock mechanism and placed in the position regulation state. It turns out.

In FIG. 1, the intermediate portion 11B of the shift lever 11 is a hollow body provided with an engagement pin 17 that extends outwardly through the intermediate portion 11B. As shown in FIG. 3, the spindle 19 attached to a bracket 18 fixed to the vehicle body is inserted through the spindle 19 so as to be freely rotatable, and is connected to a rotating cylindrical body 20 covered with a cover 13. There is.

As shown in FIG. 3, a push rod 22 having a piston member 21 at its lower end is disposed inside the intermediate portion 11B of the shift lever 11, and the engagement pin 17 is connected to the piston member. 21 and protrudes to the outside of the intermediate portion 11B of the shift lever 11 through a pair of elongated holes 11C formed opposite to each other in the intermediate portion 11B of the shift lever 11. Furthermore, a piston member 21 inside the intermediate portion 11B of the shift lever 11
A coil spring 23 is interposed between the rotary cylindrical body 20 and the rotary cylindrical body 20 to urge the push rod 22 upward. The push rod 22 is configured to press the coil spring 23 downward against the biasing force when the lock release button 14 disposed on the knob 11A is pushed in. Therefore, the engagement pin 17 According to the operation of the lock release button 14, the shift lever 1 is moved within the range regulated by the elongated hole 11C.
1 along the intermediate portion 11B.

Further, the intermediate portion 11B of the shift lever 11 has a connecting lever 24 whose one end engages with the automatic transmission.
However, the shift lever 11 uses the rotating cylindrical body 20 as a pivot shaft.
It is attached so that it swings with the movement of the air.

[0015] In connection with the shift lever 11, an engagement pin locking plate 25 is arranged and fixed to the vehicle body. The engagement pin 17 is engaged with the engagement pin locking plate 25 when the shift lever 11, which is provided with an engagement pin 17 protruding from the intermediate portion 11B, takes a position for selecting one range.
A locking part 1α corresponding to the 1st range, with which the engagement pin 17 engages when taking the position for selecting the 2nd range, a locking part 2α corresponding to the 2nd range, the engaging pin when taking the position for selecting the D range. 17 engages, a locking portion d corresponding to the D range,
The engaging pin 17 engages when the N range is selected, and the locking part n corresponds to the N range.The engaging pin 17 engages when the R range is selected. A locking portion r corresponding to the P range is provided, and a locking portion p corresponding to the P range is engaged with the engagement pin 17 when the P range is selected. In addition, in FIG. 2, the shift lever 11 is assumed to be in a position for selecting the P range, and the engagement pin 17 is in the locking portion p corresponding to the P range.
is engaged in.

Further, an engagement pin locking member 30 is provided opposite the engagement pin locking plate 25. The lower end of this engagement pin lock member 30 is rotatably engaged with the rotary cylindrical body 20 to which the lower end of the shift lever 11 is connected. And the engagement pin lock member 30
An actuator 31 is connected to the , and the actuator 31 rotates with respect to the rotating cylindrical body 20 .
The engaging pin locking member 30 is swung around its lower end as the center of swiveling.

The engagement pin locking member 30 is swing-driven by the actuator 31 so that the engagement pin 17 provided on the shift lever 11 corresponds to the P range provided on the engagement pin locking plate 25. When brought into a state of engagement with the locking part p, the upper end 30A of the locking part p
Selectively takes a locked position below the engaging pin 17 engaged with the engaging pin 17, and an unlocked position where the engaging pin 17 is disengaged from below the engaging pin 17 engaged with the locking part p. It is said that When the upper end 30A of the engagement pin lock member 30 is in the locked position, the engagement pin 17 engaged with the locking portion p is locked by the upper end 30A of the engagement pin lock member 30. It is prevented from moving downward from the position where it is engaged with the stop part p, and is therefore restrained in the state where it is engaged with the stop part p, and placed in a position regulated state by the engagement pin lock member 30. . Under such circumstances, the shift lever 11 is restricted to the position where the P range is selected and cannot be moved to a position where any other shift range is selected. On the other hand, the engagement pin lock member 30 has its upper end 30
When A is assumed to be in the unlocked position, the engagement pin 17 engaged with the locking portion p is in the engagement pin locking member 30.
It is in a state where it can move downward without being hindered by the upper end portion 30A, and is therefore released from the state in which the position is restricted by the engagement pin locking member 30. Under such circumstances, the shift lever 11 can be freely moved from the position where the P range is selected to the position where the other shift ranges are selected.

The actuator 31 is connected to a control section 32, and the control section 32 has an ignition switch of the vehicle.
A detection output signal Si is generated from the ignition sensor 33 which detects that the key switch is turned on and generates a detection output signal Si, and a detection output signal Sb is generated by detecting the state in which the vehicle's brake system is activated. A detection output signal Sb from the brake sensor 34 is supplied. Then, the control section 32 forms a drive control signal Cr that changes according to the detection output signals Si and Sb, and supplies it to the actuator 31 to control its operation.

For example, when the ignition key switch of the vehicle is turned off and the engine mounted on the vehicle is in a non-operating state, the detection output signal Si from the ignition sensor 33 is not supplied to the control unit 32, and as a result, the , the drive control signal Cr is not supplied from the control section 32 to the actuator 31 either. In such a case, the engagement pin locking member 30 connected to the actuator 31 has its upper end 30A in the locked position. Also, the vehicle's ignition key switch is turned on,
When the engine installed in the vehicle is in operation,
A detection output signal Si is supplied from the ignition sensor 33 to the control section 32. In such a state, if the brake system of the vehicle is not activated, the detection output signal Sb from the brake sensor 34 is not supplied to the control unit 32. Even under such circumstances, the drive control signal Cr is not supplied from the control unit 32 to the actuator 31, and the engagement pin locking member 30 connected to the actuator 31 assumes that its upper end 30A is in the locked position. be done.

On the other hand, when the ignition key switch of the vehicle is turned on and the brake system of the vehicle is activated while the engine installed in the vehicle is in operation, the detection from the ignition sensor 33 In addition to the output signal Si, a detection output signal Sb from the brake sensor 34 is supplied to the control section 32. As a result, the drive control signal Cr is supplied from the control section 32 to the actuator 31, and the actuator 31 is operated to swing the engagement pin locking member 30 to the left in FIG. As a result, the engagement pin locking member 30 locks its upper end 30
It is assumed that A assumes the unlocked position.

As shown in FIG. 1, a bracket 35 is fixed to the vehicle body and faces the engagement pin locking plate 25 with the engagement pin locking member 30 in between. Fixed shaft 3 passing to bracket 35
6 is provided. Two rotary lock lever members 37 and 38 are arranged in parallel on the fixed shaft 36 so as to be rotatable with respect to the fixed shaft 36, respectively. Further, a rotating member 39 is attached to the bracket 35 with its intermediate portion 39A being pivoted, and a lower end portion 39A of the rotating member 39 is attached to the bracket 35.
B is an engagement pin 4 protruding from the engagement pin lock member 30.
0, thereby restricting the rotation of the rotating member 39 about the pivoted portion thereof. Further, above the rotating member 39, a shift lock release button 16 is arranged so as to be movable up and down. Shift lock release button 16
The lower part of the plate-like portion 16A is a plate-like portion 16A.
The lower surface of A is in contact with the upper surface of one end of the rotation lock lever member 37 and the upper end portion 39C of the rotation member 39. On the other hand, one end of the rotation lock lever member 38 has an engagement pin 1 whose lower surface protrudes from the shift lever 11.
7 from above. The rotary lock lever member 37 is rotated by a coil spring 41 disposed on the fixed shaft 36 so that the rotation lock lever member 37
The rotation lock lever member 38 is biased in the direction of rotating the one end portion that contacts A upward, and the rotation lock lever member 38 is driven by a coil spring 42 disposed on the fixed shaft 36 so that the engagement pin protrudes from the shift lever 11. 17 is biased in a direction to rotate the end portion downward.

Furthermore, an engaging member 44 provided at one end of the key interlock cable 43 is disposed on the other end side of each of the two rotation lock lever members 37 and 38 arranged in parallel. ing. A key interlock cable 43 extends from an ignition keyswitch portion 45, as shown in FIG. 4, and an engagement member 44 is coupled to the key interlock cable 43 at a terminal support portion 46. The end support portion 46 is formed by a housing 47 that partially accommodates an engagement member 44 coupled to the key interlock cable 43 and a support member 48 that supports the housing 47 and is fixed to the vehicle body. A spring 49 is compressed in the housing 47 and urges the engaging member 44 in the direction of drawing it into the housing 47, thereby causing the key having the engaging member 44 at its tip end to be biased in the direction of drawing the engaging member 44 into the housing 47. The interlock cable 43 is generally biased toward the ignition key switch portion 45 side.

The ignition key switch section 45 includes:
A fixing part 50 and a key insertion hole 51 are provided, and the fixing part 50
A cam member 52 is rotatable relative to the fixed part 50, and one end thereof is in contact with the cam surface of the cam member 50, and the other end thereof is connected to the other end of the key interlock cable 43. A cable support part 54 is provided which is attached to the coupled rotating member 53 and the fixed part 50 and supports the key interlock cable 43. Then, the key 55 is inserted into the key insertion hole 51 and engaged, and is rotated to selectively take the OFF position, the ACC position, and the ON position.
The ACC state is a state in which the key switch section 45 is in the OFF state, the ignition device is in an inactive state, but power supply voltage is supplied to electrical components, and the ACC state is a state in which power supply voltage is supplied to electrical components. In addition, the ignition device is also selectively turned on, which is the operating state. The cam member 52 rotates with the rotation of the key 55, and the movement of the cam surface causes the rotation member 5 to rotate.
3 is rotated.

The state shown in FIG. 4 is a state in which the key 55 inserted into the key insertion hole 51 is in the OFF position, and at this time, the ignition key switch portion 45 is in the OFF state, and the rotating member 53 is in the OFF position. However, the key interlock
The cable 43 is pushed out toward the end support part 46 against the urging force of a spring 49 compressed within the housing 47 of the end support part 46 . In this way, the key interlock cable 43 is pushed out from the ignition key switch part 45 side to the end support part 46 side, so that the engaging member 44 provided at one end of the key interlock cable 43 is pushed out. The rotating lock lever member 37 has a large protruding length from the housing 47, and has two distal ends disposed in parallel.
and 38, and restricts the rotation of the rotation lock lever members 37 and 38. Furthermore, with the ignition key switch section 45 in the OFF state in this manner, the key 55 can be freely inserted into and removed from the key insertion hole 51.

On the other hand, as shown in FIG. 5, the key 55 inserted into the key insertion hole 51 assumes the ACC position.
As a result, the ignition key switch section 45 is
When the CC state is entered, and furthermore, when the key 55 inserted into the key insertion hole 51 assumes the ON position, thereby turning the ignition key switch section 45 on, the rotating member 53 moves to the key interface. The lock cable 43 is pushed toward the ignition key switch section 45 by the urging force of a spring 49 compressed within the housing 47 of the end support section 46. In this way, the key interlock cable 43 is pushed from the end support part 46 side to the ignition key switch part 45 side, so that
The engagement member 44 provided at one end of the key interlock cable 43 is in a state in which its protrusion length from the housing 47 is reduced, and its tip end is connected to the two rotating lock lever members 37 arranged in parallel. and 38 to the end support portion 46 side, whereby the rotation of the rotation lock lever members 37 and 38 is not restricted by the engagement member 44. When the ignition key switch section 45 is in the ACC state or the ON state in this manner, the key 55 cannot be removed from the key insertion hole 51.

As described above, the ignition key switch section 45 is turned off, and the engagement member 44 of which the end support section 46 projects from the housing 47 has a large length. When the rotation of each of the dynamic lock lever members 37 and 38 is restricted, the shift lever 11 assumes a position for selecting the P range, and the engagement pin 1 provided on the shift lever 11
7 is placed in an engaged state with a locking portion p corresponding to the P range on the engagement pin locking plate 25. Further, the upper end portion 30A of the engagement pin locking member 30 is set to the lock position by the actuator 31, and the engagement pin 17 engaged with the locking portion p is restrained in that state, and the engagement pin lock member 30 is locked. It is assumed that the position is restricted by the member 30.

At this time, when the shift lock release button 16 is pressed, the plate-shaped portion 16A provided on the shift lock release button 16 pushes down one end of the rotation lock lever member 37, thereby releasing the rotation lock lever member 37. However, the rotation lock lever member 37 cannot be rotated because its rotation is restricted by the engagement member 44, and therefore the shift lock release button 16 cannot be pressed down. Therefore, the engagement pin 17 engaged with the locking portion p cannot be released from the position restricted state by the engagement pin locking member 30. That is, move the shift lever 11 to P.
This means that it is not possible to shift from the range selection position to the other shift range position.

[0028] Also, the ignition key switch section 4
The key 55 inserted into the key insertion hole 51 provided in 5 assumes the ACC position or ON position, and the ignition key switch section 45 is placed in the ACC or ON state. In the case where the length of the engagement member 44 protruding from the housing 47 of the shift lever 11 is made small and the rotation restriction of the rotation lock lever members 37 and 38 by the engagement member 44 is released, the shift lever 11 is assumed to be in a position for selecting the P range, and the engagement pin 17 provided on the shift lever 11 is engaged with the engagement portion p corresponding to the P range on the engagement pin engagement plate 25. When the upper end 30A of the engagement pin locking member 30 is in the locked position, when the shift lock release button 16 is pressed, the plate-shaped The portion 16A pushes down one end portion of the rotation lock lever member 37 to rotate the rotation lock lever member 37, so that the shift lock release button 16 can be pushed down.

Then, when the shift lock release button 16 is pressed down, the rotating member 39 is moved to its upper end 39.
C is a plate-shaped portion 16A provided on the shift lock release button 16
is rotated by being pushed down by
The engagement pin 40, whose lower end portion 39B projects from the engagement pin locking member 30, is pressed and moved toward the engagement member 44 side. As a result, the engagement pin lock member 30 is caused to swing toward the engagement member 44 with its lower end portion as the center of swing, and the upper end portion 30A of the engagement pin lock member 30 is moved from the locked position to the unlocked position. It will be done. As a result, the locking portion p
The engagement pin 17 engaged with the engagement pin lock member 30 is released from the position restriction state by the engagement pin locking member 30, and the shift lever 11 can be moved from the position for selecting the P range to the position for selecting another shift range. It will be possible. That is, when the key 55 inserted into the key insertion hole 51 provided in the ignition key switch section 45 assumes the ACC position or the ON position, the ignition key switch section 45 is placed in the ACC state or the ON state. In this case, the shift lock release button 16 can be operated to perform its function, and the release of the shift lever 11 from the locked state at the position where the P range is selected is determined by the definite will of the driver of the vehicle. It will be held under.

Under such conditions, the shift lever 11
is assumed to be in a position for selecting an arbitrary shift range, but the shift lever 11 is placed in a position for selecting a shift range other than the P range, and the engagement pin 17 is set in the P range on the engagement pin locking plate 25. When the key 55 is engaged with a locking portion other than the locking portion p corresponding to the locking portion P, the key 55 is engaged with the ignition key switch portion 45.
When the key interlock cable 43 is rotated to assume the OFF position, the corresponding rotation of the cam member 52 causes the rotation member 53 to rotate, thereby inserting the key interlock cable 43 into the housing 47 of the end support 46. It is pushed out from the ignition key switch section 45 side toward the end support section 46 side against the biasing force of the compressed spring 49. As a result, the protruding length of the engaging member 44 provided at one end of the key interlock cable 43 from the housing 47 increases, but at this time, the rotation lock lever member 38 is moved by the coil spring 42. The engaging member 4 is biased so as to be rotated so that the other end thereof is positioned upward, and therefore the length of the engaging member 4 protruding from the housing 47 is increased.
4 comes into contact with the end surface of the other end of the rotation lock lever member 38, and further increase in the length of the protrusion from the housing 47 is restricted.

As a result, the key interlock cable 43 cannot be pushed out from the ignition key switch section 45 side to the end support section 46 side by the rotation of the rotation member 53, and the rotation of the cam member 52 is stopped. It will be done. As a result, the key 55 engaged with the ignition key switch section 45 cannot be turned to the OFF position, and therefore the key 55 cannot be removed from the ignition key switch section 45. Become.

On the other hand, the key 55 inserted into the key insertion hole 51 provided in the ignition key switch section 45 assumes the ACC position or the ON position, and the ignition key switch section 45 is in the ACC state. Alternatively, in the on state, the shift lever 11 assumes a position for selecting the P range, and the engagement pin 1
When the engagement pin 17 is engaged with the engagement portion p corresponding to the P range on the engagement pin engagement plate 25, the engagement pin 17 engaged with the engagement portion p is brought into contact with the coil spring 42. abuts from below one end of the rotation lock lever member 38, which is biased by the rotation lock lever member 38 and is rotated so that the other end thereof is positioned upward;
One end of the rotation lock lever member 38 is moved upward to rotate the rotation lock lever member 38, and the other end of the rotation lock lever member 38 is positioned downward. Under such circumstances, the engagement member 44 whose protrusion length from the housing 47 is increased is positioned such that its tip is above the other end of each of the rotation lock lever members 37 and 38. It is considered to be taken. Therefore, when the key 55 engaged with the ignition key switch section 45 is rotated to take the OFF position, the key interlock cable 43 is inserted into the housing 47 of the end support section 46. The engaging member provided at one end of the key interlock cable 43 is pushed out from the ignition key switch section 45 side toward the end support section 46 side against the biasing force of the compressed spring 49. 44 from the housing 47 is increased, and the distal end of the engagement member 44 assumes a position above the other end of each of the rotation lock lever members 37 and 38. The operation is carried out without any trouble, and the key 55 engaged with the ignition key switch section 45 is rotated to the OFF position.
It is assumed that it can be removed from the ignition key switch section 45.

In this way, disengaging the key 55 from the ignition key switch section 45 once engaged with the ignition key switch section 45 is as follows:
This cannot be done when the shift lever 11 is placed in a position to select a shift range other than the P range, and the shift lever 11
This can only be done when the operator is placed in a position to select the P range. In other words, when the key 55 engaged with the ignition key switch section 45 is rotated to take the OFF position and removed from the ignition key switch section 45, the shift lever 11 is reliably moved to the P range. You are now in a position to select.

FIG. 6 shows a portion of another example of the automatic transmission operating device according to the present invention. In another example of the operating device for an automatic transmission according to the present invention having the portion shown in FIG. 6, the shift lever 11 shown in FIGS.
, the engagement pin lock member 30, the actuator 31, the control section 32, the shift lever 60 similar to the engagement pin locking plate 25, the engagement pin lock member 61, the actuator 6, etc.
2, a control section 63, an engagement pin locking plate 64, and the like.

In the example shown in FIG. 6, above a rotating member 66 similar to the rotating member 39 shown in FIG. The shift lock release button 67 has a downwardly extending portion 67A and is arranged to be movable up and down. Further, a slide plate member 69 supported by a guide member 68 is disposed between the shift lock release button 67 and the rotating member 66 located below the shift lock release button 67. A through hole 70 is provided through which the downwardly extending portion 67A of 67 can pass. The slide plate member 69 slides while being guided by the guide member 68, and shifts the through hole 70 at the downwardly extending portion 67A of the lock release button 67.
A state in which the through hole 70 is located directly below the shift lock release button 67 and a state in which the through hole 70 is not located directly below the downwardly extending portion 67A of the shift lock release button 67 are selectively taken.

A rotation lock lever member 72 is arranged below the slide plate member 69 and is rotatably supported by a pair of brackets 71 which are fixed to the vehicle body and face each other. The lower surface of one end of the rotation lock lever member 72 is placed in a position where the shift lever 60 selects the P range, and engages with a locking portion p corresponding to the P range on the engagement pin locking plate 64. The rotation lock lever member 72 is configured to contact the engagement pin 80 protruding from the shift lever 60 from above, and the rotation lock lever member 72 is caused to contact the engagement pin 80 protruding from the shift lever 60 by a coil spring 73. The one end that contacts 80 is biased in a direction to rotate downward.

Furthermore, an engagement member 75 provided at one end of the key interlock cable 74 is disposed on the other end side of the rotation lock lever member 72. The key interlock cable 74 is similar to the key interlock cable 43 shown in FIGS. 4 and 5;
It extends from an ignition key switch section similar to the ignition key switch section 45 shown in FIGS. 4 and 5. The engagement member 75 is coupled to the key interlock cable 74 at a terminal support 76, which is coupled to the housing 7 partially enclosing the engagement member 75 coupled to the key interlock cable 74.
7 and a support member 78 that supports the housing 77 and is fixed to the vehicle body. A spring is compressed in the housing 77 and biases the engaging member 75 in the direction of drawing it into the housing 77, thereby locking the key interlock with the engaging member 75 at its tip. The cable 74 is generally biased in the direction toward the ignition key switch section. and,
The distal end 75A of the engagement member 75 coupled to the key interlock cable 74 is connected to the engagement pin 7 provided thereon.
It is connected to the slide plate member 69 via 9.

Under such circumstances, the key is inserted into the key insertion hole of the ignition key switch section and engaged with the ignition key switch section in the same manner as in the examples shown in FIGS. 1 to 5. When the key is set to the OFF position, or when the key is not engaged with the ignition key switch section and the ignition key switch section is set to the OFF position, the key interlock is activated. - The cable 74 resists the urging force of the spring compressed in the housing 77,
Terminal support part 76 from the ignition key switch part side
The engaging member 75 is pushed to the side.
The protrusion length of the terminal end support portion 76 from the housing 77 is made large. At this time, the shift lever 60 is placed in a position for selecting the P range, and as shown in FIG. 6, the engagement pin 80 protruding from the shift lever 60 corresponds to the P range on the engagement pin locking plate 64. It is supposed to engage with the locking part p. The distal end portion 75A of the engagement member 75, which has a large protruding length from the housing 77 in the terminal end support portion 76, has a lower surface of one end that corresponds to the P range of the engagement pin locking plate 64. A slide plate member connected to the other end of the rotation lock lever member 72 that is placed above the other end of the rotation lock lever member 72 that is in contact with the engagement pin 80 of the shift lever 60 that is engaged with the shift lever 60. 69, the engagement member 75 has a large protruding length from the housing 77, so that it is slid in a direction away from the end support portion 76, and as shown in FIG. The release button 67 is not positioned directly below the downwardly extending portion 67A.

In such a case, even if the shift lock release button 67 is pressed, the downwardly extending portion 67 of the shift lock release button 67
The lower end surface of A comes into contact with the slide plate member 69 supported by the guide member 68, and the shift lock release button 67 cannot be pressed down. Therefore,
The downwardly extending portion 67A of the shift lock release button 67 comes into contact with the rotating member 66 disposed below and cannot be rotated, and the engagement pin locking plate 64 is not engaged with the P range corresponding to the P range. The engagement pin 80 of the shift lever 60, which is to be engaged with the stop part p, is inserted into the engagement pin locking member 61.
This means that it will not be possible to release the position from the position restriction state. That is, the shift lever 60 cannot be moved from the position where the P range is selected to the position where any other shift range is selected.

On the other hand, in the same way as in the examples shown in FIGS. 1 to 5, the key inserted into the key insertion hole provided in the ignition key switch section assumes the ACC position or the ON position. It is said that the ignition
When the key switch section is placed in the ACC or ON state, the key interlock cable 74 is pushed from the end support section 76 toward the ignition key switch section by the biasing force of the spring compressed in the housing 77. Therefore, the engaging member 7
The protrusion length of the end support portion 76 of No. 5 from the housing 77 is made small. As a result, the tip end 7 of the engagement member 75
The slide plate member 69 connected to the end support portion 7
6 so that the through hole 70 is positioned directly below the downwardly extending portion 67A of the shift lock release button 67.

At this time, when the shift lock release button 67 is pressed, the downwardly extending portion 67A of the shift lock release button 67 passes through the through hole 70 provided in the slide plate member 69. The downwardly extending portion 67A of the shift lock release button 67 extends downward through the through hole 70 provided in the slide plate member 69, and its lower end portion is attached to the rotating member 66. The rotating member 66 is pressed from above by contacting the upper end portion 66C and rotated. Lower extending portion 67A of shift lock release button 67
The rotating member 66 that has been rotated presses and moves the engagement pin 65 that protrudes from the engagement pin locking member 61 that is in contact with it. As a result, the engagement pin lock member 61 is caused to swing around its lower end, and
The upper end portion 61A of the engagement pin locking member 61 is moved from the locked position to the unlocked position, and as a result, it engages with the locking portion p of the engagement pin locking plate 64 corresponding to the P range. The engagement pin 80 of the shift lever 60 is released from the position restricted state by the engagement pin locking member 61, and the shift lever 60 is moved from the position where the P range is selected to the position where the shift range is selected. It is considered possible to do so. In other words, the key inserted into the key insertion hole provided in the ignition key switch section assumes the ACC position or the ON position, and when the ignition key switch section is in the ACC or ON state, the shift This means that the lock release button 67 can be operated to perform its function, and the shift lever 60 can be released from the locked state at the position where the P range is selected, with the sure will of the driver of the vehicle. It will be done.

Furthermore, under such a condition, the shift lever 60 is assumed to be in a position where it selects an arbitrary shift range, but it is assumed that the shift lever 60 is placed in a position where it selects a shift range other than the P range. , the engagement pin 80 of the shift lever 60 is attached to the engagement pin engagement plate 64 at engagement portions 1α, 2α, d, other than the engagement portion p corresponding to the P range.
When the key is engaged with n and r, the key engaged with the ignition key switch section is turned OFF.
When the key interlock cable 74 is rotated to take the position, the key interlock cable 74 is pulled away from the ignition key switch section against the biasing force of a spring compressed in the housing 77 of the end support section 76. It is assumed that it is pushed out toward the end support portion 76 side. As a result, the protrusion length of the engaging member 75 provided at one end of the key interlock cable 74 from the housing 77 increases, but at this time, the rotation lock lever member 72
is biased by a coil spring 73, and is rotated so that the other end is positioned upward, and therefore, the length of the engagement from the housing 77 is increased. The member 75 comes into contact with the end surface of the other end of the rotation lock lever member 72, and further increase in the length of the protrusion from the housing 77 is restricted.

As a result, the key interlock cable 74 cannot be pushed out from the ignition key switch section side to the end support section 76 side, and the key engaged with the ignition key switch section is rotated to the OFF position. Therefore, the key cannot be removed from the ignition key switch section.

On the other hand, the key inserted into the key insertion hole provided in the ignition key switch section
The shift lever 60 is assumed to be in the C position or ON position, and the shift lever 60 is assumed to be in the P range selection position when the ignition key switch section is in the ACC or ON state. When the pin 80 is brought into engagement with the locking portion p corresponding to the P range on the engagement pin locking plate 64, it engages with the locking portion p corresponding to the P range on the engagement pin locking plate 64. The engagement pin 80 of the shift lever 60 is in a state where
is biased by the coil spring 73, and the other end of the rotation lock lever member 72 is rotated to the upper position.
Abutting the rotation lock lever member 72 from below, moving one end of the rotation lock lever member 72 upward to rotate the rotation lock lever member 72, and positioning the other end of the rotation lock lever member 72 downward. let Under such circumstances, the engagement member 75 whose protrusion length from the housing 77 is increased is positioned such that its tip 75A is above the other end of the rotation lock lever member 72. be done. Therefore, when the key engaged with the ignition key switch section is rotated to take the OFF position, the key interlock cable 74 is compressed into the housing 77 of the terminal support section 76. against the biasing force of the spring, the ignition
The operation of pushing out from the key switch section side to the end support section 76 side causes the engagement member 75 provided at one end of the key interlock cable 74 to protrude from the housing 77 by increasing its protrusion length. The distal end 75A of the rotary lock lever member 75 assumes a position above the other end of the rotary lock lever member 72 without any trouble, and the key engaged in the ignition key switch section is turned OFF.
It is assumed that it can be rotated to the F position and removed from the ignition key switch section.

[0045] In this way, disengaging the key once engaged with the ignition key switch section from the ignition key switch section means that the shift lever 60 is placed in a position where a shift range other than the P range is selected. This cannot be done when the shift lever 60 is in the position where the P range is selected. In other words, when the key engaged with the ignition key switch section is rotated to take the OFF position and removed from the ignition key switch section, the shift lever 60 reliably selects the P range. It will be placed in position.

FIG. 7 shows a portion of still another example of the automatic transmission operating device according to the present invention. Even in the example of the operating device for an automatic transmission according to the present invention having the portion shown in FIG. 7, the shift lever 1 shown in FIGS.
1. Shift lever 85 similar to the engagement pin lock member 30, actuator 31, control unit 32, engagement pin lock plate 25, etc., engagement pin lock member 86, actuator 87, control unit 88, engagement pin lock It is assumed that it is equipped with a plate 89 and the like.

In the example shown in FIG. 7, a pair of brackets 91 and 92 that face each other are fixed to the vehicle body, and a pair of brackets 91 and 92 that are provided on the bracket 91 and extend in the vertical direction are provided. The elongated hole and the through hole, the three through holes provided in the bracket 92, and
The elevating member 95 is attached using two attachment pins 93 and 94. The elevating member 95 is provided with a pair of elongated holes 98 extending in the vertical direction through which the two mounting pins 93 pass through, and an elongated hole 99 extending in the vertical direction through which the mounting pin 94 passes.
00, and can move up and down in parallel with brackets 91 and 92. A shift lock release button 101 is provided at one end of the lifting member 95.
Although not shown, below one end of the lifting member 95 where the shift lock release button 101 is provided, the engagement pin 102 protruding from the engagement pin lock member 86 is engaged. Rotating member 39 shown in FIG.
A rotating member similar to that is arranged.

Further, a rotation lock lever member 103 is rotatably supported by a mounting pin 94 that connects the bracket 91 and the bracket 92. The lower surface of one end of the rotating lock lever member 103 is placed in a position where the shift lever 85 selects the P range, and engages with a locking portion p corresponding to the P range on the engagement pin locking plate 89. The rotation lock lever member 103 contacts the engagement pin 90 protruding from the shift lever 85 from the upper side, and the rotation lock lever member 103 is connected to the engagement pin 90 protruding from the shift lever 85 by a coil spring 104. The one end that abuts is biased in a direction to rotate downward.

Furthermore, an engaging member 106 provided at one end of the key interlock cable 105 is disposed on the other end side of the elevating member 95. The key interlock cable 105 is similar to the key interlock cable 43 shown in FIGS. 4 and 5, and the ignition key switch section 45 shown in FIGS.
It extends from an ignition key switch section similar to the above and is supported by a terminal support section 107. Engagement member 106
is connected to the key interlock cable 105 within the housing 108 of the end support portion 107, and is inserted into the key insertion hole of the ignition key switch portion, similar to the engaging member 44 shown in FIG. The key that is supposed to be engaged with the ignition key switch section is set to the OFF position, or the key is not engaged with the ignition key switch section, and the ignition key switch section is turned OFF. When the terminal support part 107 is assumed to take a state
The protrusion length from the housing 108 is made large, and the key inserted into the key insertion hole provided in the ignition key switch section assumes the ACC position or the ON position, so that the ignition key switch section When in the ACC state or on state, the protrusion length of the end support portion 107 from the housing 108 is made small.

Housing 10 at end support 107
The distal end of the engagement member 106 having a large protrusion length from the engagement pin 89 is located below the other end of the elevating member 95, and the lower surface of one end is engaged with the engagement pin engagement plate 89 corresponding to the P range. It is located above the other end of the rotation lock lever member 103 which is in contact with the engagement pin 90 of the shift lever 85 which is engaged with the portion p. In such a case, even if the shift lock release button 101 is pressed, the other end of the elevating member 95 comes into contact with the tip of the engaging member 106 and the downward movement of the elevating member 95 is prevented. It is assumed that the shift lock release button 101 cannot be pushed down. Therefore, shift lock release button 1
One end of the elevating member 95 provided with 01 cannot be brought into contact with the rotating member disposed below and rotated, which corresponds to the P range of the engagement pin locking plate 89. The engagement pin 90 of the shift lever 85, which is supposed to engage with the locking portion p, cannot be released from the position restricted state by the engagement pin locking member 86. That is, the shift lever 85 cannot be moved from the position where the P range is selected to the position where any other shift range is selected.

In contrast, the engagement member 1 in which the protruding length of the end support portion 107 from the housing 108 is made small
06 is connected to the housing 1 from a position between the other end of the lifting member 95 and the other end of the rotation lock lever member 103.
It is assumed that it has moved to a position close to 08. and,
At this time, when the shift lock release button 101 is pressed, the shift lock release button 101 moves downward as the elevating member 95 descends within the range of the elongated holes 98 and 99 provided in the elevating member 95. One end of the elevating member 95 provided with the shift lock release button 101 contacts a rotating member disposed below the elevating member 95 to rotate it. As a result, the rotating member swings the engagement pin lock member 86 around its lower end, and moves the upper end 86A of the engagement pin lock member 86 from the locked position to the unlocked position. As a result, the engagement pin 90 of the shift lever 85, which is supposed to engage with the engagement portion p corresponding to the P range on the engagement pin engagement plate 89, is released from the position restricted state by the engagement pin locking member 86. The shift lever 85 can be moved from a position where the P range is selected to a position where another shift range is selected.

Further, under such a condition, the shift lever 85 is assumed to be in a position where it selects an arbitrary shift range, but it is assumed that the shift lever 85 is in a position where it selects a shift range other than the P range. , the engagement pin 90 of the shift lever 85 is attached to the engagement pin engagement plate 89 at engagement portions 1α, 2α, d, other than the engagement portion p corresponding to the P range.
When the key is engaged with n and r, the key engaged with the ignition key switch section is turned OFF.
When the engagement member 106 is rotated to assume the position, the protrusion length of the engagement member 106 from the housing 108 increases, but at this time, the rotation lock lever member 10
3 is biased by a coil spring 104 and rotated so that the other end thereof is positioned upward, and therefore, the length of the engagement portion protruding from the housing 108 is increased. The distal end of the mating member 106 comes into contact with the end surface of the other end of the rotation lock lever member 103, and further increase in the length of the protrusion from the housing 108 is restricted. As a result, the ignition
The key engaged with the key switch section cannot be rotated to the OFF position, and therefore the key cannot be removed from the ignition key switch section.

On the other hand, the key inserted into the key insertion hole provided in the ignition key switch section
The shift lever 85 is assumed to be in the C position or the ON position, and the shift lever 85 is assumed to be in the P range selection position when the ignition key switch section is in the ACC or ON state. When the pin 90 is brought into engagement with the locking portion p corresponding to the P range on the engagement pin locking plate 89, it engages with the locking portion p corresponding to the P range on the engagement pin locking plate 89. The engagement pin 90 of the shift lever 85 is in the state where
comes into contact from below with one end of the rotation lock lever member 103, which is biased by the coil spring 104 and is rotated so that the other end is positioned upward; Rotation lock lever member 103
Rotating lock lever member 10 by moving one end upward
3 to make the rotation lock lever member 103 take a state in which the other end is positioned downward. Under such circumstances, the engagement member 106 whose protrusion length from the housing 108 is increased is positioned such that its tip is above the other end of the rotation lock lever member 103. Ru. Therefore, when the key engaged with the ignition key switch portion is rotated to take the OFF position, the engaging member 106
The projecting length from the housing 108 is increased without any problem, and the key engaged with the ignition key switch section is rotated to the OFF position and removed from the ignition key switch section. It is considered possible to do so.

[0054] In this way, disengaging the key once engaged with the ignition key switch section from the ignition key switch section means that the shift lever 85 is placed in a position where a shift range other than the P range is selected. This means that it cannot be done under the same roof, and can only be done when the shift lever 85 is in the position to select the P range.
When the key engaged with the ignition key switch section is rotated to take the OFF position and removed from the ignition key switch section, the shift lever 85 is surely placed in the position for selecting the P range. This means that

[0055]

As is clear from the above description, the automatic transmission operation device according to the present invention allows the shift lever to select the P range from among a plurality of shift ranges in the automatic transmission to For example, if a predetermined condition such as the vehicle's brake system being activated is not met, the predetermined condition is not satisfied when the vehicle is in a position restriction state in which it is restricted to the position where the P range is selected. a shift lock mechanism that releases the position from a position restriction state in which the P range is selected only when A shift lock release mechanism section that releases the shift lock release mechanism from the position restriction state by manual operation is connected to the key switch via the key switch coupling section, and the key switch is operated by engaging the key with the key switch. Only under this condition, the shift lock release mechanism can perform an operation to release the shift lever from the position restriction state in which the shift lever is restrained to a position for selecting the P range by the shift lock mechanism, and The key engaged with the key switch can be removed from the key switch only when the shift lock mechanism section puts the shift lever in a position-restricted state in which it is restrained at a position for selecting the P range.

Therefore, the shift lock release mechanism can release the shift lever from the position restriction state where the shift lock mechanism restricts the shift lever to the position for selecting the P range. ,
This is done based on the driver's will, and the shift lock release mechanism is operated without the vehicle driver's will, and the shift lock release mechanism is locked in the position where the P range is selected due to normal operation of the shift lock mechanism. This prevents a situation in which the shift lever, which has been placed in a position-restricted state, is undesirably released from the position-restricted state. Also, when the key is removed from the key switch and the driver leaves the vehicle,
The shift lever is securely locked by the shift lock mechanism.
The user is restricted to the position where the P range is selected and is placed in a position restricted state.
