Rear differential gear lock controller with automatic unlock control means

摘要

A rear differential gear allows to be locked by a differential gear lock switch at speeds less than a first set vehicle speed, prohibited from being locked at speeds greater than or equal to the first set vehicle speed, and automatically unlocked if the locked state elapses a predetermined period of time at speeds greater than or equal to a second set vehicle speed that is greater than the first set vehicle speed. Therefore, it can prevent reduction in driving stability due to the under-steering in a turning, even if a driver has forgotten unlocking the locked rear differential gear by operating the differential gear lock switch in a rear differential lock controller.
