Method and apparatus for automatic steering control of automobile
First Claim
1. A method of automatic steering control of an automobile, comprising the steps of:
- detecting a white line drawn on a road by camera means;
determining a distance of the white line detected at the detecting step with respect to a view axis of the camera means;
transforming the distance determined at the determining step into a corresponding distance of the white line with respect to a prescribed point on a central axis of the automobile;
calculating a steering angle according to the corresponding distance obtained at the transforming step; and
controlling a steering of the automobile according to the steering angle calculated at the calculating step such that the automobile follows the white line.

Abstract
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.
