The invention relates to a vehicle steering control method and a vehicle steer-by-wire device, and belongs to the technical field of automobile steering systems. The method comprises the steps: when steering operation is determined, controlling a power-assisted steering component of the vehicle to drive steering wheels of the vehicle to steer, so that the vehicle is steered; when it is determinedthat steering operation is conducted and the power-assisted steering component fails, acquiring a target braking force needed by all wheels of the vehicle, and determining the target braking force bystate information of the vehicle; and corresponding target braking force is applied to all the wheels, so that the vehicle is steered. By the adoption of the power-assisted steering control method anddevice, the situation that the vehicle with the steer-by-wire function loses the steering function when the power-assisted steering component of the vehicle fails can be avoided, and therefore the safety of the vehicle can be improved.

    本申请是关于一种车辆转向的控制方法和车辆的线控转向装置,属于汽车的转向系统技术领域。该方法包括当确定转向操作时,控制车辆的转向助力部件驱动车辆的转向轮转向,以使所述车辆转向;当确定转向操作且所述转向助力部件失效时,获取所述车辆的各个车轮所需的目标制动力,所述目标制动力由所述车辆的状态信息确定;向所述各个车轮施加对应的目标制动力,以使所述车辆转向。采用本申请,可以避免具有线控转向功能的车辆在其转向助力部件失效时丧失转向功能,从而可以提高车辆的安全性。
