The central control unit 18 controls an actuator 71 such as a motor for switching a manual shift valve (not shown) as a range switching valve. That is, the manual shift valve is a spool-type valve similar to a manual shift valve in a conventional automatic transmission that manually switches the range, and is supplied with a line hydraulic pressure serving as a base pressure for control and drive, and is operated in accordance with a shift position. The hydraulic pressure is supplied to a predetermined friction engagement device (not shown) along a route corresponding to each travel range.

Next, the shift device 13 of the first embodiment is described.
The operation of will be described. In the initial state of the shift device 13, that is, in the state where the engine EG is stopped, the operation knob 16
Is assumed to indicate "P". As a result, the fixed electrode 24a and the sliding electrode 26 are electrically connected, and the stop position signal is input to the central control unit 18. Further, the plunger 19a is located at the lock position, the operation knob 16 is in a rotation disabled state (mechanical operation locked state), and the push button 17 is in a pressed operation disabled state (mechanical operation locked state).

When the power switch S provided on the instrument panel 12 is pressed, the central controller 18 outputs a judgment request signal to the head amplifier 36, and the head amplifier 36 amplifies the judgment request signal. . Then, the head amplifier 36 outputs a determination request signal to the coil 21. When the card key 32 is moved closer to the shift device 13 in this state, the coil 21 transmits a determination request signal to the transponder 32a. When the determination request signal is input, the transponder 32a outputs the immobilizer identification code to the coil 2.
1 to the head amplifier 36 and the head amplifier 3
6 outputs the immobilizer identification code to the central control unit 18.

The central control unit 18 compares the input immobilizer identification code with the vehicle-mounted identification code stored in advance, and when they match, recognizes the identification code (identification signal) of the authorized user. The recognition information is stored.

When the brake pedal 37 is depressed in this state, the brake switch 37a outputs a braking detection signal to the central control unit 18. The central controller 18 stores the key recognition information and outputs an excitation signal to the solenoid 19 based on the input of the braking detection signal. That is, under the condition that the engine EG is not driven, the central control unit 18 performs the AND condition between the key recognition information for which the recognition result is obtained as the identification code of the authorized user and the input of the braking detection signal. Only the solenoid 19 is unlocked.

The solenoid 19 moves the plunger 19a from the lock position to the unlock position based on the excitation signal. Then, the push button 17 is in a press-enabled state (operable state), and the operation knob 16 is in a rotatable state (operable state). Then, in this state, as shown in FIG.
9 conducts (turns on) the pair of fixed electrodes 27 a, and outputs an engine start signal to the central control unit 18. The central controller 18 controls the engine EC based on the engine start signal.
An engine drive permission signal is output to U70. The engine ECU 70 starts the engine EG based on the engine drive permission signal.

Thereafter, when the operation knob 16 is operated to rotate from the position "P" to the position "R" while the brake pedal 37 is depressed, the fixed electrode 24b and the sliding electrode 26 are electrically connected. The reverse position signal is input to the central control unit 18. The central control unit 18 controls and drives the actuator 71 based on the reverse position signal.

Thereafter, after the engine EG is driven by the engine ECU 70, when the depression operation of the brake pedal 37 is released, the brake switch 37a is released.
The central control unit 18 demagnetizes the solenoid 19 on the basis of the braking release signal from. Therefore, the plunger 19a of the solenoid 19 is moved to the lock position side by the spring 20, but since the operation knob 16 is rotating, the lock hole 16e is not opposed to the plunger 19a in this state, and the plunger 19a is It comes into contact with the rear surface of the operation knob 16.

When the operation knob 16 is further operated and rotated to indicate "N", the fixed electrode 24c is displaced.
And the sliding electrode 26 are electrically connected to each other,
Is supplied with a neutral position signal. Based on the neutral position signal, the central control unit 18 controls the actuator 71 according to the neutral position.

When the operating knob 16 is operated and rotated to indicate "D", the fixed electrode 24d and the sliding electrode 26 are electrically connected, and the central control unit 18 sends a drive position signal to the central control unit 18. Is entered. The central controller 18 controls the actuator 71 according to the drive position based on the drive position signal.

When the brake pedal 37 is not depressed, the indication mark 30 on the operation knob 16 is turned on.
Is operated and rotated from any one of "R", "N" and "D" to the position "P", the lock hole 16e is opposed to the plunger 19a, so the plunger 19a is It moves to the lock position by the urging of. Then, the tip of the plunger 19a is inserted into the through hole 15b.
And the operation knob 16 is locked in the lock hole 16e.

During the operation of the engine EG, the plunger 19a of the solenoid 19 depresses the brake pedal 37, and when the brake switch 37a outputs a braking detection signal to the central control unit 18, the central control unit 18 drives and controls the solenoid 19. The plunger 19a is moved to the unlock position. Therefore, the engine EG
When the instruction mark 30 of the operation knob 16 is moved from the position "P" to any one of "R", "N" and "D" during driving, the card key 32 needs to be collated again. Instead, it is only necessary to depress the brake pedal 37.

When the engine EG is stopped, the power switch S is pressed while the indication mark 30 of the operation knob 16 indicates "P". Then, the central control unit 18 outputs an engine stop signal to the engine ECU 70, and based on the engine stop signal, the engine ECU 7
0 stops the engine EG.

Therefore, the shift device 1 according to the first embodiment described above.
According to 3, the following effects can be obtained. (1) In the present embodiment, the push button 17 is
Provided in itself. When the engine EG is stopped, the detection means (the central control unit 18 and the coil 21)
When the brake pedal 37 is depressed and the brake switch 37a outputs a braking detection signal to the central control unit 18, the central control unit 18
The 9 plunger 19a is moved from the locked position to the unlocked position. As a result, the pressing button 17 is in a state where the pressing operation is possible, and the operation knob 16 is in a state where the operating knob 16 is rotatable. Therefore, when the engine EG is stopped, the central control unit 18 serving as the detecting means operates the card key 32.
The operation knob 16 is in a non-rotatable state, and the push button 17 is also in a non-pressable state, unless the user confirms that the user is an authorized user. In addition, since the operation knob 16 cannot be turned unless the brake pedal 37 is depressed, sudden start of the vehicle can be prevented.

(2) In this embodiment, the push button 17 is provided on the operation knob 16 in a housed state. Therefore, as compared with the case where the push button 17 and the operation knob 16 are provided separately from each other, the shift device 13 can reduce the number of components, and can realize space saving and compactness. This is an advantageous configuration when unitized.

(3) In this embodiment, a single solenoid 19 is used for both the operation knob 16 and the push button 17.
, The operation device can be locked or the mechanical operation can be locked, so that the shift device 13 can be configured at a lower cost than when the solenoid 19 is provided on each of the operation knob 16 and the pressing button 17.
