    Abstract: PROBLEM TO BE SOLVED: To prevent trouble or discomfort from being caused by that headlights are lit or extinguished due to the influence of dark or white clouds within a visual field range of an illuminance sensor regarding a light-automatic-lighting control unit.SOLUTION: A front illuminance sensor that detects an illuminance in front of a vehicle and an upper direction region illuminance sensor that detects an illuminance of an upper direction region of the vehicle are included. If both outputs of the illuminance sensors are lower than an illuminance threshold Don, headlights are lit. If both the outputs of both the illuminance sensors become equal to or larger than an illuminance threshold Doff higher than the illuminance threshold Don, the headlights are extinguished. In particular, since a visual field range of the upper direction region illuminance sensor 14 is equal to or larger than βn (=45°) that is wider than the conventional visual field range βo, even if white or dark cloud CL appears in the sky, an area ratio by which the cloud CL occupies the visual field range of the upper direction region illuminance sensor 14 reduces to decrease the influence of the cloud, and the output of the upper direction region illuminance sensor 14 does not cross the illuminance threshold Don or Doff. Therefore, the lit or extinguished state of the headlights remains unchanged, and tentative lighting or extinguishing is prevented.

    Abstract translation: 要解决的问题：为了防止由于照明传感器关于光自动照明控制单元的视场范围内的暗云或白云的影响而使头灯被点亮或熄灭引起的麻烦或不适。解决方案： 包括检测车辆前方的照度的前照度传感器和检测车辆的上方方向区域的照度的上方方向区域照度传感器。 如果照度传感器的两个输出都低于照度阈值Don，则前灯亮起。 如果两个照度传感器的输出都变得等于或大于比照度阈值Don高的照度阈值Doff，则头灯熄灭。 特别地，由于上方方向区域照度传感器14的视野范围等于或大于比常规视野范围＆bgr; o宽的n（= 45°），即使白色或深色云CL 出现在天空中，云CL占据上方向区域照度传感器14的视场范围的面积比减小，以减小云的影响，并且上方向区域照度传感器14的输出不会越过 照度阈值Don或Doff。 因此，前灯的点亮或熄灭状态保持不变，防止了暂时的照明或熄灭。
