The embodiment of the invention provides a control method and device for a vehicle differential lock. The control method comprises the steps that a vehicle body electronic stability control system detects whether the condition for requesting locking of a differential lock of a vehicle differential mechanism is met or not in real time; when it is detected that the condition for requesting locking of the differential lock is met, the vehicle body electronic stability control system sends a signal for requesting locking of the differential lock and a signal for requesting reduction of the output torque to the whole vehicle controller; and in response to the signal requesting to reduce the output torque, when the locking condition of the differential lock is met, the vehicle control unit controls the differential lock to conduct locking. Therefore, the condition for requesting locking of the differential lock of the vehicle can be automatically monitored, automatic locking of the differential lock is achieved when the condition is met, and manual locking control is not needed.

    本申请实施例提供一种车辆差速锁的控制方法及其控制装置。该控制方法包括:车身电子稳定控制系统实时检测是否满足请求车辆差速器的差速锁锁止的条件;在检测到满足请求差速锁锁止的条件时,车身电子稳定控制系统向整车控制器发送请求差速锁锁止的信号及请求降低输出扭矩的信号;以及响应于请求降低输出扭矩的信号,在符合差速锁锁止的条件时,整车控制器控制差速锁进行锁止。从而,能够自动监控请求车辆差速锁锁止的条件,并在条件满足时实现差速锁的自动锁止,无需手动控制锁止。
