It is possible to experience the end of switching the A / T 6 to the parking position.

Further, when the shift lever 38 is shifted to the P position, the locking portion 2 of the wire cable 25 is moved.
5a contacts the locking piece 24a of the drive plate 24. At this time, when the motor 10 is driven and the outer lever 12 is rotationally driven, the rotational force is transmitted to the drive plate 24 via the wire cable 25, and the driving force of the motor 10 switches the manual valve 16 to the P position. To be If the power cable of the battery is disconnected or the voltage of the battery drops while the vehicle is traveling, the motor 1
It becomes impossible to drive 0. At this time, a rotational force is applied to the drive plate 24 via the wire cable 25 connected to the shift lever 38, the outer lever 12 is rotationally driven, and the manual valve 16 is switched to the P position.

The shift device 36 is provided with a shift detection sensor 48 (see FIG. 3) for electrically detecting the shift operation of the shift lever 38. This shift detection sensor 48
Includes a P position sensor 50 for detecting a shift operation of the shift lever 38 to the P position. As shown in FIG. 2B, the P position sensor 50 has a first position.
It is arranged near the intersection of the guide groove 43 and the circle, and electrically detects the shift operation of the lever 38 to the P position side during the shift operation to the P position.

In the vehicle according to this embodiment, as an electronic control unit (ECU) which plays a role as the above-mentioned control system, an engine ECU (“E” mainly for controlling the operation of the engine 2).
/ GECU ”) 52, and an A / TECU 54 that mainly controls the A / T 6 described above. Each ECU 52, 54
Are electrically connected to each other through an in-vehicle network line.

A microcomputer is mainly used as the E / GECU 52. The E / GECU 52 suitably controls the engine 2 by driving a fuel injection valve, an igniter, or other actuators based on detection signals from various sensors.

The A / TECU 54 includes the shift device 36.
The detection signal of the shift detection sensor 48 including the P position sensor 50 in FIG. A / TECU 54
Is a read-only memory (ROM) in which a microcomputer is used to store programs necessary for various software processes related to the shift position switching of the A / T 6 and the automatic switching of each shift speed in the forward traveling position, and this program. It mainly includes a central processing unit (CPU) for executing the above, a writable memory (RAM) for temporarily storing variables necessary for a program, and the like.

The A / TECU 54 controls the drive of the motor 10 based on the detection signal of the shift detection sensor 48 in the operating state of the engine 2, and switches the position of the manual valve 16 to switch the position of the A / T 6. . In addition, the A / T ECU 54, at that position, changes the A / T ECU 54 according to the vehicle speed and the engine load at that time.
The gear ratio of 6 is controlled.

FIG. 5 shows an example of shift control when the A / T6 position is switched to the P position. Now, after the vehicle is stopped, the shift lever 38 is shifted to the P position. When the shift lever 38 passes the P position sensor 50 at the timing t1, the P position sensor 50 detects the shift operation of the shift lever 38 to the P position. At this time,
If there is no battery power interruption or brownout,
The motor 10 can be driven by supplying a predetermined electric power to the motor 10.

At timing t2, a control signal is output from the A / TECU 54 based on the detection signal of the P position sensor 50, and the motor 10 is rotationally driven so as to switch the manual valve 16 to the P position. Therefore, the manual valve 16 is switched to the P position at the timing t2.

Thereafter, the wire cable 25 moves in the direction of arrow A in response to the shift operation of the shift lever 38 to the P position, but the drive plate 24 has already been rotated in the direction of arrow A by the motor 10. Therefore, the rotational force is not transmitted to the drive plate 24 via the wire cable 25, and the shift lever 38 shifts the first guide groove 4 at the timing t3.
It can be easily operated up to P position 3 with a small shift load.

On the other hand, when the P position sensor 50 detects the shift operation of the shift lever 38 to the P position at the timing t1, if the battery power is cut off or the voltage is reduced, the motor 10 is determined to have a predetermined value. The electric power cannot be supplied and the motor 10 cannot be driven. Therefore, at timing t2, the motor 10 is not rotationally driven as shown by the chain line, and the manual valve 16 is not yet switched to the P position.

After that, the wire cable 25 moves in the direction of arrow A in response to the shift operation of the shift lever 38 to the P position. When the locking portion 25a of the wire cable 25 comes into contact with the locking piece 24a of the drive plate 24, the shift lever 3
8 shift operation is performed by the drive plate 2 via the wire cable 25.
4 and the drive plate 24 is rotated in the direction of arrow A.
At this time, the shift load of the shift lever 38 increases as the manual valve 16 is switched.

When the shift lever 38 is shifted to the P position of the first guide groove 43 at the timing t3, the manual valve 16 is switched to the P position.

According to this embodiment described above, the following effects can be obtained. In the present embodiment, the shift lever 3 of the shift device 36
Reference numeral 8 is connected to a drive plate 24 of the outer lever 12 via a wire cable 25. And the shift lever 38
The wire cable 25 abuts the drive plate 24 in a drivable manner during the shift operation to the P position. If the power cable of the battery is disconnected and power is cut off, or the voltage of the battery drops, the motor 1
If 0 cannot be driven, the manual valve 16 of the A / T 6 cannot be switched to the P position.
In this case, the shift operation of the shift lever 38 can be transmitted to the outer lever 12 via the wire cable 25 and the drive plate 24 to switch the manual valve 16 to the P position, and the A / T 6 can be reliably shifted to the P position. Can be done.

In the shift device 36 of the present embodiment, the P position sensor 50 that detects the operation to the P position side is provided in the middle of the first guide groove 43 that guides the shift operation of the shift lever 38. When the P position sensor 50 detects the shift operation of the shift lever 38 to the P position, the A / TECU 54 causes the motor 1 to move.
The manual valve 16 is switched to the P position by driving and controlling 0. Therefore, in the state where the power from the battery is not cut off or the voltage of the battery is not reduced, the motor 10 is controlled based on the detection signal of the P position sensor 50 that detects the operation of the shift lever 38 to the P position side to operate the manual valve 16. You can switch to the P position. At this time, since the shift operation of the shift lever 38 is not transmitted to the outer lever 12, the force for driving the outer lever 12 and the manual valve 16 is unnecessary, and a small shift load for shifting the shift lever 38 is sufficient.

In the shift device 36 of the present embodiment, the shift lever 38 can be moved from the operation center position to a plurality of operation positions along the guide groove 42, but returns to the operation center position when in the non-operation state. . Therefore, the shift device 36 can be downsized, and the operability of the shift lever 38 can be improved.

In the shift device 36 of the present embodiment, the parking position and the neutral position, which are non-driving positions, are set on the first guide groove 43, and the R position and the D position, which are driving positions, are on the second guide groove 44. The shift operation can be intuitively performed without being aware of the operation position, and the shift operability can be improved.
