The embodiment of the invention provides a differential protection method and system, a vehicle and electronic equipment. The method comprises the steps that the actual rotating speed of each wheel and the actual rotating speed of a driving motor are obtained; under the condition that the actual rotating speed of each wheel and/or the actual rotating speed of the driving motor are/is abnormal, the change rate of the actual rotating speed of the driving motor is determined; when the change rate of the actual rotating speed of the driving motor is abnormal, the request torque of the driving motor is set to be zero, so that the driving motor stops providing driving force for the differential mechanism, and the situation that the differential mechanism is burnt out due to abnormal acceleration can be effectively avoided.

    本申请实施例提供了一种差速器保护方法、系统、车辆以及电子设备,所述方法包括:获取各个车轮的实际转速和驱动电机的实际转速;在所述各个车轮的实际转速和/或所述驱动电机的实际转速发生异常的情况下,确定所述驱动电机的实际转速的变化率;在所述驱动电机的实际转速的变化率发生异常的情况下,将所述驱动电机的请求扭矩设置为零,以使所述驱动电机停止向所述差速器提供驱动力,可以有效避免差速器因异常加速而出现烧毁的情况。
