    • A control unit of a vehicular headlamp apparatus can selectively perform steering angle control and navigation-cooperative control. The steering angle control operates a drive mechanism based on a steering angle and a speed of a vehicle to control a headlamp's swivel angle. The navigation-cooperative control operates the drive mechanism using a navigation unit to control the swivel angle. When a current position of the vehicle reaches an entry control start point, the control unit starts navigation-cooperative control at the entry into a curved road. The control unit finds a target swivel angle based on a curvature radius and curved road direction information about the curved road. While the vehicle moves from the entry control start point to a curved road start point, the control unit operates the drive mechanism to gradually change the headlamp's swivel angle to the target swivel angle.
    • 车辆用前照灯装置的控制单元可以选择性地执行转向角控制和导航协作控制。 转向角控制基于车辆的转向角和速度来操作驱动机构,以控制前照灯的旋转角度。 导航协作控制使用导航单元来操作驱动机构来控制旋转角度。 当车辆的当前位置到达进入控制开始点时,控制单元在弯曲道路的入口处开始导航协作控制。 控制单元基于曲率半径和关于弯曲道路的弯曲道路路线信息来找到目标旋转角度。 当车辆从进入控制开始点移动到弯曲的道路起点时,控制单元操作驱动机构,以将前照灯的旋转角度逐渐改变为目标旋转角度。
