A method can synchronize movement between a feedback actuator and a steering actuator in a steer-by-wire steering system of a motor vehicle. The steer-by-wire steering system may include a steering wheel, a feedback actuator connected to the steering wheel for providing road feedback to a driver, road wheels, and a steering actuator with an electric motor that operates in response to detected values of various steering parameters and orientates the road wheels in a desired direction. The method may involve detecting with an angle sensor a rotation of the electric motor's rotor caused by movement of the road wheels or the steering wheel. If movement is detected, a position change can be registered in a storage means. Upon ignition on, the feedback actuator or the steering actuator may be moved in accordance with the stored position change to maintain synchronization.
