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.

Abstract translation: 当锁定构件从锁定位置切换到释放位置时，锁定阀切换部分将锁定阀从锁定状态切换到释放状态。 当经过时间时，当先导压力等于或大于预定压力时，错误操作监视部件将锁定阀保持在释放状态，该时间是从锁定部件从锁定位置切换到释放的时间 位置等于或大于预定时间。 当经过时间小于预定时间时，当先导压力等于或大于预定压力时，错误操作监视部分将锁定阀切换到锁定状态。
