Abstract
A system for lane centering control for a vehicle having a user-operable steering device is disclosed. The system includes a set of sensors for sensing the vehicle speed, yaw rate, and steering device angle, a target path tracker configured for tracking the target path of the vehicle, a processor responsive to the set of sensors for predicting the path of the vehicle, a controller responsive to the set of sensors, the target path tracker, and the processor, and productive of a lane centering control signal, and an active front steering actuator responsive to the control signal and productive of steering assistance to the steering device. The controller includes a processing circuit responsive to executable instructions for producing the steering assistance to the steering device to reduce a difference between the predicted path and the target path, thereby serving to maintain lane centering of the vehicle.
