Disclosed herein are two exemplary steer-by-wire control systems comprising: a road wheel unit responsive to a road wheel command signal including a road wheel position sensor and a road wheel sensor. The steer-by-wire control system also includes a steering wheel unit responsive to a steering wheel torque command signal, including a steering wheel position sensor and a torque sensor. The steer-by-wire control system further includes a vehicle speed sensor, and a master control unit operatively connected to the vehicle speed sensor, the steering wheel unit, and the road wheel unit. The road wheel unit is also responsive to the road wheel force signal and/or the steering wheel unit is also responsive to the steering wheel position signal. Further disclosed are two methods for steering a vehicle with a steer-by-wire system comprising: receiving a road wheel force signal, a road wheel position signal, a vehicle speed signal, a steering wheel position signal, and a feedback torque sensor signal, and generating a steering wheel torque command signal. The method for steering a vehicle further includes generating a road wheel command signal responsive to the road wheel position signal, the vehicle speed signal, the feedback torque sensor signal, and the steering wheel position signal. The method for steering a vehicle further includes generating a force compensated position command signal in a road wheel unit responsive to the road wheel force signal and/or generating a position compensated torque command signal in a steering wheel unit responsive to the steering wheel position signal. |
