Abstract:
A lane tracking control system for a vehicle, comprising:a road image detector taking a view ahead of the vehicle; a vehicle behavior detector detecting a behavior of the vehicle; a steering control mechanism executing a steering control in response to a steering control signal; and a controller coupled to the road image sensor, the vehicle behavior detector and the steering control mechanism, the controller being arranged, to calculate a road shape on the basis of the view taken by the road image detector, to determine whether the vehicle tends to depart from a lane traveled by the vehicle, on the basis of the road shape and the vehicle behavior detected by the vehicle behavior detector, to output the steering control signal to the steering control mechanism to control the vehicle behavior at a desired behavior when the vehicle tends to depart from the lane, wherein the vehicle behavior detector comprises a steering torque sensor, a turn signal lamp, a vehicle speed sensor and a yaw rate sensor.
