A method and an apparatus for automatic steering control of an automobile, which can be carried out efficiently by using only one regression equation for calculating a steering angle. In the apparatus, a white line drawn on a road is detected by camera; a distance of the detected white line with respect to a view axis of the camera is determined; the determined distance is transformed into a corresponding distance of the white line with respect to a prescribed point on a central axis of the automobile; a steering angle is calculated according to the obtained corresponding distance; and a steering of the automobile is controlled according to the calculated steering angle such that the automobile follows the white line.
