Patent ID: 7118237

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