The invention discloses a steer-by-wire fault emergency method and device, a vehicle and a storage medium. The method comprises the following steps: receiving a fault signal of the steer-by-wire system; determining a fault state of the steer-by-wire system according to the fault signal; if the fault state is that the steering hand feeling feedback subsystem loses efficacy, controlling an interaction system to display a fault state prompt and a preset device control strategy; and a control signal of the preset control device is received, and vehicle steering is controlled according to the control signal. According to the technical scheme, the problem that the steering of the vehicle cannot be controlled due to failure of the steering hand feeling feedback subsystem is solved, and the effects that when the steering hand feeling feedback subsystem fails, the vehicle is controlled to run safely through the preset control device, potential safety hazards caused by the failure of the steer-by-wire system of the vehicle are reduced, and user safety is guaranteed are achieved.

    本发明公开了一种线控转向故障的应急方法、装置、车辆及存储介质。该方法包括:接收线控转向系统的故障信号;根据所述故障信号确定所述线控转向系统的故障状态;若所述故障状态为转向手感反馈子系统失效,则控制交互系统显示故障状态提示和预设装置控制策略;接收所述预设控制装置的控制信号,根据所述控制信号控制车辆转向。通过本发明的技术方案,解决转向手感反馈子系统失效无法控制车辆转向的问题,实现在转向手感反馈子系统失效时,通过预设控制装置控制车辆安全行驶,降低车辆由于线控转向系统故障所带来的安全隐患,保证用户安全的效果。
