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.
