The invention discloses a vehicle differential lock control strategy. The vehicle differential lock control strategy comprises a main driving shaft inter-wheel differential lock control strategy, a second driving shaft inter-wheel differential lock control strategy, an inter-shaft differential lock control strategy and a main driving shaft inter-wheel differential lock control strategy, if the vehicle speed is zero, executing a locking instruction, and if not, ending the program. And the switching signal of the inter-wheel differential lock of the main driving shaft is unlocking. When the inter-axis differential lock state signal is unlocking, an unlocking instruction is executed; when the state signal of the inter-axle differential lock is locked and the state signal of the inter-wheel differential lock of the second driving axle is unlocked, an unlocking instruction is executed; and when the state signal of the inter-axle differential lock is locked and the state signal of the inter-wheel differential lock of the second driving axle is locked, the program is ended. The method has low requirements on vehicle driving technology, and can protect reliable operation of vehicle parts in real time.

    本发明公开了一种车辆差速锁控制策略,包括主驱动轴轮间差速锁控制策略、第二驱动轴轮间差速锁控制策略、轴间差速锁控制策略,主驱动轴轮间差速锁控制策略:主驱动轴轮间差速锁开关信号为上锁时。车速为0执行上锁指令,车速不为0程序结束。主驱动轴轮间差速锁开关信号为解锁时。轴间差速锁状态信号为未锁执行解锁指令;轴间差速锁状态信号为锁止且第二驱动轴轮间差速锁状态信号为未锁时执行解锁指令;轴间差速锁状态信号为锁止且第二驱动轴轮间差速锁状态信号为锁止时程序结束。本发明对车辆驾驶技术要求不高,能够实时保护车辆零部件可靠性运行。
