Steer-by-wire redundant handwheel control

The present disclosure relates to a vehicular steer-by-wire system, and more particularly, to a redundant sub-system for providing controllability in the event of a partial system failure. An apparatus and method for steering a vehicle (not shown) provides an input member or steering wheel for receiving steering inputs from a user; a steering-torque sensor mechanically coupled to the input member for sensing the torque applied to the steering wheel; a control circuit electronically coupled to the steering-torque sensor for producing a signal corresponding to the measured driver steering torque; an output actuator electronically coupled to the control circuit and road wheel for receiving the electronic signal and translating it into mechanical motion; and an output member or road wheel mechanically coupled to the output actuator for steering the vehicle (not shown).
