Abstract
A lock valve is switched from lock condition to release condition when a lock member is switched from lock position to release position. When pilot pressure is at least a predetermined pressure when the elapsed time from the point at which the lock member is switched from lock position to release position is at least a first predetermined time, the lock valve is maintained in the release condition. When pilot pressure is at least the predetermined pressure, the continuous time duration is greater than the second predetermined time when the elapsed time is less than the first predetermined time, the lock valve is switched to the lock condition. When pilot pressure is at least the predetermined pressure, the continuous time duration is no more than the second predetermined time when the elapsed time is less than the first predetermined time, the lock valve is allowed to be switched.
