The invention discloses a differential protection method for a double-rear-drive-axle commercial vehicle, electronic equipment and a vehicle. The double-rear-drive-axle commercial vehicle comprises a first rear drive axle and a second rear drive axle. The method comprises the steps that the wheel speed of each wheel of the double-rear-drive-axle commercial vehicle is obtained; calculating a wheel speed difference according to the wheel speed of each wheel of the commercial vehicle with the double rear drive axles; state data of the double-rear-drive-axle commercial vehicle are obtained; determining whether a differential protection function starting condition is met or not according to the wheel speed difference and the state data of the double-rear-drive-axle commercial vehicle; under the condition that the differential protection function starting condition is met, the road condition category is determined; determining a motor torque according to the wheel speed difference and the road condition category; and the commercial vehicle with the double rear drive axles is controlled according to the motor torque. The road condition category is determined after the differential protection function is started, and the motor torque is determined according to the road condition category and the wheel speed difference, so that the motor torque under the differential protection function better conforms to the current road condition, and the differential is effectively protected.

    本发明公开了一种双后驱桥商用车的差速器保护方法、电子设备及车辆。所述双后驱桥商用车包括第一后驱桥和第二后驱桥,所述方法包括:获取双后驱桥商用车的各车轮的轮速;根据双后驱桥商用车的各车轮的轮速计算轮速差;获取双后驱桥商用车的状态数据;根据轮速差以及双后驱桥商用车的状态数据确定是否满足差速器保护功能启动条件;在满足差速器保护功能启动条件的情况下,确定路况类别;根据轮速差和路况类别确定电机扭矩;根据电机扭矩对双后驱桥商用车进行控制。本发明通过在差速器保护功能启动后确定路况类别,并根据路况类别和轮速差确定电机扭矩,使得在差速器保护功能下的电机扭矩更符合当前路况,实现对差速器的有效保护。
