Abstract:
A deviation controller to prevent deviation of a vehicle from a lane of travel includes a displacement estimator configured to estimate a future lateral displacement of the vehicle with respect to the lane of travel, a detecting device configured to detect a tendency of the vehicle to deviate from the lane of travel, a prevention controller configured to apply a yaw moment to correct a travel path of the vehicle when the tendency of the vehicle to deviate from the lane of travel is detected, a correction canceling device configured to cancel the yaw moment of the prevention controller when a steering angle exceeds a canceling threshold, and a threshold adjusting device configured to adjust the canceling threshold in response to the estimated future lateral displacement.
