Abstract: A method to control a steer-by-wire steering system of a road vehicle including a steering wheel coupled to a steering shaft, a road wheel actuator to turn steerable road wheels, a shaft sensor to detect a rotation of the steering shaft and a controller configured or programmed to generate an operation signal for the road wheel actuator from a signal detected by the shaft sensor, includes determining a real steering wheel angle by the shaft sensor, modifying the real steering wheel angle by applying an artificial hysteresis to create an offset between the real steering wheel angle and a modified steering wheel angle to mimic a behavior of an electromechanical power steering mechanism, and generating the motor torque request for the road wheel actuator based on the modified steering wheel angle.
