Abstract
A vehicle steering control system for conducting a steering assistance control in which a basic steering assist torque is determined based on a structural parameter relating to the lane structure such as its curvature. In parallel, corrective steering assist torques are determined based on positional parameters of the vehicle relating to the lane such as a lateral deviation from the lane center line and a vehicle heading angle, and are added to the basic steering assist torque to correct the same. Since the positional parameters are determined based on the image information at or close to the vehicle, this enables to determine the steering assist torque adequately, thereby enhancing the accuracy of the steering assistance control.
