DRIVER ASSIST SYSTEM FOR VEHICLE

A driver assist system for avoiding hunting of an assist control. The driver assist system comprises: an edge line detector that detects edge lines of a predetermined lane; a limit steering angle detector that detects a limit steering angle at which a vehicle reaches the edge line in a predetermined time; an actual steering angle detector that detects an actual steering angle from a reference position; a comparator that compares the actual steering angle with the limit steering angle; a steering assistor that establishes a steering reaction force when the actual steering angle exceeds the limit steering angle; a determiner that determines a satisfaction of a condition relating to a lane width; and an adjustor that imaginarily sets the right edge line and the left edge line on the center of the lane, and calculate the limit steering angle based on the imaginary edge line upon the satisfaction of the condition.
