The invention discloses an overload protection control method and device for a vehicle steering system, a vehicle and a medium, and belongs to the technical field of vehicles. The overload protection control method comprises the steps that operation signals of a left front steering motor, a right front steering motor, a left rear steering motor and a right rear steering motor are obtained; when the running signal of any steering motor is an overload signal, a turning angle signal or a torque signal of a steering wheel of the vehicle is obtained; and when the change amplitude of the steering angle signal or the torque signal within the preset time is within the preset threshold range, all the steering motors are controlled to stop running, the driving system is controlled to drive the vehicle to reversely move by the preset distance and then stop running, and active intervention can be conducted for control when the steering motors are overloaded by executing the steps, so that the safety of the vehicle is improved. The vehicle can be separated from road shoulders or other obstacles, the vehicle is protected against damage to parts such as wheels caused by collision, protection of the four-wheel steering system is achieved, and driving safety is improved.

    本发明公开了一种车辆转向系统的过载保护控制方法、装置、车辆及介质,属于车辆技术领域,其中过载保护控制方法包括:获取左前转向电机、右前转向电机、左后转向电机和右后转向电机的运行信号;当任意一个转向电机的运行信号为过载信号时,获取车辆的方向盘的转角信号或扭矩信号;当转角信号或扭矩信号在预设时间内的变化幅度在预设阈值范围内时,控制所有的转向电机停止运行,并控制驱动系统驱动车辆反向移动预设距离后停止运行,通过执行上述步骤能够在转向电机出现过载时主动介入进行控制,使车辆能够脱离路肩或其他障碍物,保护车辆免受碰撞带来的对车轮等零部件的损害,实现对四轮转向系统的保护,提高驾驶安全性。
