    • 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.
    • 用于自动调节车辆前灯的光轴方向的装置包括转向角传感器,车速传感器,存储多个控制图的存储器,每个控制图限定转向角和转角之间的关系, 处理单元,用于执行根据车速和转向角来选择多个控制图中的一个的地图切换,以及用于从初始方向将车辆前灯的光轴旋转的致动器, 由由处理单元选择的多个控制图之一限定的旋转角度。 当转向角改变到围绕方向盘的中立角位置的预定角度范围之外时,处理单元执行地图切换。
