The invention discloses a steering protection device and method, a steering control system and a vehicle, and the steering protection device comprises a displacement sensor which is installed on a steering shaft rack; a torque sensor which is used for monitoring stress information of front wheels of the vehicle; buffer units which are arranged on transmission paths between the front wheels of the vehicle and the steering shaft rack, connected with a power-assisted steering machine and used for controlling the connection state of the front wheels of the vehicle and the steering shaft rack; and an electronic control unit which is used for determining whether the collision degree of the front wheels of the vehicle meets a preset abnormal condition according to the stress information, the displacement change information and the torque information collected by the torque sensor, and if yes, a control signal is sent to the power-assisted steering machine, so that the power-assisted steering machine controls the buffer unit to disconnect the steering shaft rack from the front wheels. The protection device is beneficial to protect steering system components of the vehicle and improve the driving safety.

    本发明公开了一种转向保护装置、方法、转向控制系统及车辆,所述转向保护装置包括:位移传感器,安装在转向轴齿条上;力矩传感器,用于监测车辆前轮的受力信息;缓冲单元,分别设置在车辆前轮与所述转向轴齿条之间的传动路径上,与助力转向机连接,用于控制车辆前轮与转向轴齿条的连接状态;电子控制单元,用于根据受力信息、位移变化信息以及扭矩传感器采集的扭矩信息,确定车辆前轮的受撞击程度是否满足预设异常条件,若是,则向助力转向机发出控制信号,使得助力转向机控制缓冲单元脱开转向轴齿条与所述前轮的连接。该保护装置有利于保护车辆的转向系统部件,提高驾驶安全性。
