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.

Abstract: A lock valve switching section switches a lock valve from a locked state to a released state when a lock member is switched from a locked position to a release position. An erroneous operation monitoring section maintains the lock valve in the released state when the pilot pressure is equal to or more than a predetermined pressure when elapsed time, which is from a point in time where the lock member is switched from the locked position to the release position, is equal to or more than the predetermined time. The erroneous operation monitoring section switches the lock valve to the locked state when the pilot pressure is equal to or more than the predetermined pressure when the elapsed time is less than the predetermined time.
