1. A steer-by-wire steering system for a road vehicle, the steer-by-wire steering system comprising:
a road wheel actuator to act on steerable wheels and electronically controlled as a function of a driver's steering request;
a feedback actuator to transmit reactions of a road to a steering wheel; and
a steering wheel angle sensor to measure a steering wheel angle; wherein
the steering wheel angle sensor is an external sensor capable of communicating on a second vehicle communication channel or via a private communication with the road wheel actuator;
the external steering wheel angle sensor is the only steering wheel angle sensor;
the steer-by-wire steering system further comprises an external road wheel actuator position sensor to measure a position of the road wheel actuator and is capable of communicating on the second vehicle communication channel or via the private communication with the road wheel actuator.
