The invention provides a vehicle differential protection method and system, electronic equipment and a readable storage medium, and relates to the technical field of driving control. The method comprises the steps that the wheel speed difference change rate of a first side wheel and a second side wheel of a target vehicle within a target duration is determined through a brake control unit; wherein the first side wheel and the second side wheel are side wheels which are located on different side edges of the target vehicle and are connected through a common transmission mechanism; sending a first torque reduction request to a motor control unit based on the wheel speed difference change rate through a brake control unit; controlling a power motor to reduce the motor torque based on the first torque reduction request through a motor control unit; the transmission mechanism comprises a differential mechanism, and the power motor is connected with the differential mechanism and provides power for the differential mechanism based on control of the motor control unit. The change rate of the speed difference of the wheels on the two sides is detected to serve as a trigger signal of a differential protection program, the trend of abnormal conditions such as slipping can be recognized earlier, and therefore the timeliness of protecting the differential is effectively improved.

    本申请提供一种车辆差速器保护方法、系统、电子设备及可读取存储介质,涉及驾驶控制技术领域。该方法包括:通过制动控制单元,确定目标车辆的第一侧轮和第二侧轮在目标时长内的轮速差变化率;其中,第一侧轮和第二侧轮为位于目标车辆的不同侧边并由共同的传动机构连接的侧轮;通过制动控制单元,基于轮速差变化率向电机控制单元发送第一降扭请求;通过电机控制单元,基于第一降扭请求控制动力电机降低电机扭矩;其中,传动机构包括差速器,动力电机连接差速器,并基于电机控制单元的控制为差速器提供动力。通过检测两侧轮速差变化率作为差速器保护程序的触发信号,能够更早识别打滑等异常情况的趋势,从而有效地提高了对差速器进行保护的及时性。
