Abstract
A lane tracking control system for a vehicle includes a controller which is coupled to a road image detector for taking a view ahead of the vehicle, a vehicle behavior detector for detecting a behavior of the vehicle and a steering control mechanism for executing a steering control in response to a steering control signal. The controller is arrange to calculate a road shape on the basis of the view taken by the road image detector, to determine on the basis of the road shape and the vehicle behavior detected by the vehicle behavior detector whether the vehicle tends to depart from a lane traveled by the vehicle, and to output the steering control signal to the steering control mechanism so as to control the vehicle behavior at a desired behavior when the vehicle tends to depart from the lane.
