Method and system for lane centering control
First Claim
1. A system for lane centering control for a vehicle having a user-operable steering device, comprising:
- 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;
wherein the controller comprises 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.

13. A method for lane centering control for a vehicle having a user-operable steering device, the vehicle disposed to traverse a target path, the method comprising:
-
sensing the vehicle speed, yaw rate, and steering device angle; tracking the target path of the vehicle; sensing a predicted path of the vehicle; in response to the sensed vehicle speed, yaw rate, and steering device angle, and in response to information relating to the target path and predicted path of the vehicle, producing a lane centering control signal; and in response to the lane centering control signal, actuating an active front steering actuator to produce 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
