Abstract
A steer-by-wire steering system includes two rack position sensors each configured to detect the position of a rack to operate a road wheel angle of a steered wheel, two road wheel actuators (RWAs) each configured to operate the rack based on an output of the corresponding rack position sensor, and a single hand wheel actuator (HWA) electrically coupled to the RWAs and configured to apply an operation reaction force to a steering wheel configured to steer a vehicle. An output signal of one of the rack position sensors is inputted to the corresponding one of the RWAs via the HWA. An output signal of the other rack position sensor is directly inputted to the other RWA.
