摘要： A steering system providing an assist torque to a handwheel is provided, and includes a proportional gain module and a torque command module. The proportional gain module determines a proportional gain value. The proportional gain value is scheduled as a function of a lateral position error and at least one of the following: a near field heading angle, a far field heading angle, a curvature of the lane, and a lateral position of the vehicle. The torque command module determines the torque assist based on the proportional gain value.

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.

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.
