摘要： A control-by-wire control system comprising a plurality of control device(s), each control device is responsive to, and configured to receive a control signal. Also included in the control-by-wire control system is a plurality of sensors wherein certain sensors are coupled to particular control devices. The sensors, each sense a parameter of the system and generate various sensor signals in response. A plurality of control modules is also included in control-by-wire control system. Each control module is interfaced to at least one of the control devices and is adapted to receive at least one or more sensor signals. The control modules also generate control signals for communication to the control devices. A communication interface of at least two communication networks provides communications among various control modules.

摘要： 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.
