Apparatus and method for automatically adjusting optical axis of vehicle headlights

摘要

In a headlight optical axis adjusting apparatus and method for a vehicle, the shape of a road in front of the vehicle is detected by a CCD camera (19) based on a change in lane marking line (100L, 100R) which indicates the lane width on the road, before the steering angle of a vehicle steering wheel (15) is detected by a steering angle sensor (16). Left and right swivel lights (11L and 11R) of the vehicle are swiveled and adjusted based on the change in the lane marking line or the steering angle. The optical axis of the left or right swivel light (11L or 11R) is first swiveled and adjusted based on the change in the lane marking line. The driver's forward visibility can thus be improved before the driver turns the steering wheel (15). <IMAGE>
