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.

A method to control a steer-by-wire steering system for a road vehicle including a steering device, a road wheel actuator to actuate road wheels, and a controller configured or programmed to generate a motor torque request for the road wheel actuator based on an actual or an estimated position and a position request, which is based on the position of the steering device, includes detecting a road wheel actuator power limit situation, modifying the position request so that it can be followed by the road wheel actuator within power limits, and using the modified position request to generate the motor torque request for the road wheel actuator.
