Abstract
A steer-by-wire steering system for a vehicle is provided that includes a steering wheel actuator for moving and detecting movements of a steering wheel of the vehicle. The steering wheel actuator includes a steering wheel electric motor. The steer-by-wire steering system further includes an axle actuator for moving and detecting movements of wheels of an axle of the vehicle. The axle actuator includes an axle electric motor and an axle control unit. The steer-by-wire steering system an equivalent circuit, which measures a current induced by the steering wheel electric motor and provides the axle control unit with at least one measurement value depending on the induced current for controlling the axle electric motor.
