- FIG. 5 is a flowchart showing lock control by the lock mechanism control unit 86.
- step S1 the lock mechanism control unit 86 (specifically, the abnormality determination unit 102) detects the throttle opening detection unit 90, the engine rotation speed detection unit 92, the vehicle speed detection unit 96, the position detection unit 100, and the vehicle speed change. It is determined whether or not an abnormality has occurred in the ABS control unit 98 as a rate detection unit.
- the abnormality determination unit 102 determines whether or not an abnormality has occurred based on a signal input to the lock mechanism control unit 86, that is, the output of the detection units 90, 92, 96, 100, and 98.

Specifically, the signal input determination unit 86B determines whether or not the input condition is satisfied. The input condition is satisfied when all of the following conditions 6 and 7 are satisfied. Condition 6: The operation signal D6 is input. Condition 7: The operation signal D6 input in a state satisfying the current lock condition is not continuously input from the time when the previous lock condition is satisfied.
- the signal input determination unit 86B determines whether or not the operation signal D6 is input. Condition 6 is satisfied when the operation signal D6 is input.
- the operation signal D6 may be input before the lock condition is satisfied as shown in FIG. 6, or may be input after the lock condition is satisfied as shown in FIG. 6 and 7, the link mechanism 36 is in a locked state when the lock condition is satisfied. This indicates that the operation for bringing the link mechanism 36 into the locked state is started when the lock condition is satisfied. 6 and 7, the link mechanism 36 is in the unlocked state when the lock condition is no longer satisfied. This indicates that an operation for bringing the link mechanism 36 to the unlocked state is started when the lock condition is not satisfied.
- the signal input determination unit 86B (specifically, the input period determination unit 106) is continuously input from the time when the operation signal D6 input in a state satisfying the current lock condition satisfies the previous lock condition. Judge whether or not. As shown in FIG. 8, when the operation signal D6 input in a state satisfying the current lock condition is not continuously input from the time when the previous lock condition is satisfied, the condition 7 is satisfied. On the other hand, as shown in FIG. 9, when the operation signal D6 input in a state satisfying the current lock condition is continuously input from the time when the previous lock condition is satisfied, the condition 7 is not satisfied. . 8 and 9, the link mechanism 36 is in a locked state when the lock condition is satisfied.
