摘要： An automotive steer-by-wire system is disclosed that includes a first network. The first network connects a first set of controllers for controlling a first set of motors. The steer-by-wire system further includes a second network that is independent of the first network and connects a second set of controllers for controlling a second set of motors. The steer-by-wire system includes a third network that connects the first set of controllers and the second set of controllers for controlling the first or second set of motors if the first or second network is inoperative, whereby information is transmitted via the third network independent of the first network and the second network.

摘要： A hybrid steer-by-wire and mechanical steering system for a vehicle includes two subsystems. The first subsystem connects a steering wheel with a mechanical link adapted to turn a first wheel of the vehicle. The second subsystem has an electro-mechanical actuator adapted to turn a second wheel of the vehicle. An electronic controller adapted to receive information indicative of the positions of the steering wheel and the first wheel controls the electro-mechanical actuator to thereby control the position of the second wheel.

摘要： A method for synchronizing data utilized in a redundant, closed-loop feedback control system is disclosed. In an exemplary embodiment, the method includes configuring a plurality of control nodes within the control system, with each of the plurality of control nodes transmitting and receiving data through a common communication bus. At each of the plurality of control nodes during a given control loop time T=N, the receipt of externally generated data with respect to each control node is verified, the externally generated data having been generated during a preceding control loop time T=N−1. At each of the plurality of control nodes during the given control loop time T=N, output control data is calculated using the externally generated data. During the given control loop time T=N, the calculated output control data from each individual control node is further transmitted over the communication bus to be later utilized by other control nodes during a subsequent control loop time T=N+1.
