Abstract
The apparatus for automatically adjusting a direction of a light axis of a vehicle headlight includes a steering angle sensor, a vehicle speed sensor, a memory for storing a plurality of control maps each of which defining a relationship between the steering angle and a swiveling angle, a processing unit for performing a map switchover by which one of the plurality of the control maps is selected depending on the vehicle speed and the steering angle, and an actuator for swiveling, from an initial direction, the light axis of the vehicle headlight by the swiveling angle defined by one of the plurality of control maps selected by the processing unit. The processing unit performs the map switchover when the steering angle is changed to outside a predetermined angular range around a neutral angular position of the steering wheel.
