Claims (1)
準照度以下のとき照明灯を自動的に点灯すると共に、外
界照度が基準照度以上のときは照明灯を自動的に消灯す
るよう構成された車両用自動点灯制御装置において、前
記照度センサめ出力電圧の低下したときの変化時間を監
視することにより一時的な照度変化か或は継続的な照度
変化かを判別子る電圧上昇率検出回路を設け、一時的な
照度変化の場合には照明灯を点灯状態に保持するよう構
成したことを特徴とする車両用自動点灯制御装置。The illuminance sensor detects the brightness of the outside world, and when the outside illuminance is below the standard illuminance, the illumination light is automatically turned on, and when the outside illuminance is above the standard illuminance, the illumination light is automatically turned off. The automatic lighting control device for a vehicle includes a voltage increase rate detection circuit that determines whether the illuminance change is a temporary change or a continuous change by monitoring the change time when the output voltage of the illuminance sensor decreases. 1. An automatic lighting control device for a vehicle, characterized in that the automatic lighting control device is configured to maintain the illumination lamp in a lit state in the event of a temporary change in illuminance.
