Abstract: A vehicle and a vehicle steering control system and method are provided in the present disclosure. The control system includes: a steering wheel; a steering wheel steering angle sensor, configured to acquire rotation information of the steering wheel; a steering wheel drive unit, the steering wheel drive unit being connected to the steering wheel, and configured to drive the steering wheel to rotate; a steering mechanism, the steering mechanism being configured to drive wheels of the vehicle to rotate; a wheel steering angle sensor, configured to detect rotation information of the wheels; and a control module, the control module being electrically connected to the steering mechanism, the wheel steering angle sensor, the steering wheel steering angle sensor, and the steering wheel drive unit separately, the control module being configured to: obtain the rotation information of the wheels before the vehicle enters a steering-wheel driving mode, and control the steering wheel drive unit according to the rotation information of the wheels to drive the steering wheel to rotate until a rotation angle of the steering wheel is the same as a rotation angle of the wheels, so as to ensure that the rotation angle of the steering wheel is the same as the rotation angle of the wheels and ensure that the moving direction of the vehicle is accurately determined.
