The invention relates to a wheel steering mechanism, and discloses a four-wheel steering system steering angle response method, a vehicle and a storage medium, and the four-wheel steering system steering angle response method comprises the steps of obtaining a steering angle request; whether the four-wheel steering system fails or not is judged, and when the four-wheel steering system fails, the failure state of the four-wheel steering system is obtained; determining a corresponding response strategy according to the failure state; and judging whether the four-wheel steering system continues to execute the steering angle request or not according to the response strategy. According to the method, different response strategies are set to be matched with the failure states, so that the four-wheel steering system has respondable execution strategies in different failure states, and the problem that whether the steering angle request continues to be executed or not cannot be judged when signal interaction between the four-wheel control system and the whole vehicle control system goes wrong is effectively solved; therefore, the safety of automatic driving is improved.

    本发明涉及车轮的转向机构,公开了四轮转向系统转角响应方法、车辆及储存介质,其中,四轮转向系统转角响应方法包括:获取转向角度请求;判断四轮转向系统是否失效,当四轮转向系统失效时,获取四轮转向系统的失效状态;根据失效状态确定对应的响应策略;根据响应策略判断四轮转向系统是否继续执行转向角度请求。本发明设置不同的响应策略与失效状态相互配对,使得四轮转向系统在不同的失效状态下具有可响应的执行策略,有效解决四轮控制系统与整车控制系统信号交互出现问题时无法判断是否继续执行转向角度请求的问题,从而提高自动驾驶行车时的安全性。
