The invention discloses a rear wheel steering fault processing system and method and a vehicle, and is applied to the technical field of vehicle control, the system comprises a rear wheel steering system, a redundant steering system and a connecting assembly, and the connecting assembly is configured to electrically connect the rear wheel steering system and the redundant steering system in an open state; the rear wheel steering system is used for driving rear wheels of the vehicle to steer; the redundant steering system is used for controlling the connecting assembly to be in an open state when it is detected that the rear wheel steering system breaks down, and controlling the rear wheel steering system according to the steering angle and the lateral acceleration of a steering wheel of the vehicle so that the rear wheel steering system can drive the rear wheels to return to the preset neutral position. The hardware cost of the vehicle can be reduced, the lateral movement risk of the whole vehicle can be effectively reduced, the abrasion degree of rear wheels of the vehicle is reduced, and the driving safety of the vehicle is improved.

    本申请公开了后轮转向故障处理系统、方法和车辆,应用于车辆控制技术领域,系统包括:后轮转向系统、冗余转向系统和连接组件,连接组件被配置为在开启状态下将后轮转向系统和冗余转向系统进行通电连接;后轮转向系统用于驱动车辆的后轮进行转向;冗余转向系统用于当检测到后轮转向系统故障时,控制连接组件处于开启状态,并根据车辆的方向盘转角和侧向加速度,对后轮转向系统进行控制,以使后轮转向系统驱动后轮返回至预设的中位位置。本申请不仅能够降低车辆的硬件成本,还能够有效地降低车辆的整车侧向移动风险,减轻车辆的后轮磨损程度,提升车辆的驾驶安全性。
