Abstract
A steer-by-wire control system comprising a master control system, a road wheel system, and a hand wheel system is disclosed. The road wheel system is connected to the master control system and includes a road wheel position sensor and a rack force sensor. The hand wheel system is connected to the master control system and the road wheel system and includes a hand wheel position sensor and a torque sensor. The steer-by-wire system also includes a vehicle speed sensor for producing a vehicle speed signal. In addition a hand wheel actuator configured to receive commands from the hand wheel system and a road wheel actuator configured to receive commands from the road wheel system are utilized. The hand wheel system and road wheel system each include a configurable control topology.
