The invention relates to the technical field of vehicles, in particular to a differential protection method and device, a vehicle, a medium and a program.The method comprises the steps that the speed difference of left and right wheels of a driving motor and the allowable peak torque of a bridge under the differential-speed-free working condition are recognized; when the speed difference of the left wheel and the right wheel of the driving motor is in a preset differential interval, the active differential protection function and/or the traction force control function of the differential mechanism are/is activated, and the maximum torque allowed to be output under differential protection is obtained; and the output torque of the driving motor is controlled to be reduced to the maximum torque allowed to be output under differential protection. Therefore, the problems that if the TCS function is not activated or fails, the electric drive differential mechanism is prone to failing, the vehicle breaks down, the service life of the vehicle is shortened, and the use safety of a user is affected in the prior art are solved.

    本申请涉及车辆技术领域,特别涉及一种差速器的保护方法、装置、车辆、介质及程序,其中,方法包括:识别驱动电机左右轮速差和无差速工况下电桥允许峰值扭矩;当驱动电机左右轮速差处于预设差速区间,则激活差速器的主动差速保护功能和/或牵引力控制功能,并获取差速保护下允许输出的最大扭矩;控制驱动电机的输出扭矩降低至差速保护下允许输出的最大扭矩。由此,解决了相关技术中若TCS功能未激活或失效则容易出现电驱差速器失效并导致车辆发生故障,降低车辆寿命,影响用户使用安全等问题。
