determining, via the controller, based on the location of the road boundary whether the vehicle will be the acceptable distance from the road boundary; and
providing a feedback operation to assist the driver in avoiding the road boundary based on the selected parameter, including applying an assist force on a portion of a steering system of the vehicle to cause movement of the vehicle away from the boundary, the assist force being calculated using a predetermined period of time of a speed of a steering operation during previous driving maneuvers, and when the speed of the steering operation during previous driving maneuvers increases, a predetermined period of time of applying the assist force is decreased.
