Abstract

본 발명은 자동차 헤드램프 자동오프 장치에 관한 것으로서, 자동차 배터리(B)의 전원공급라인에 병렬로 릴레이스위치 K1 및 K2를 개재하여 연결되고 헤드램프스위치의 SW3의 작동에 의해 접속되어 차량의 좌우헤드램프(L1,L2)에 전원이 공급되는 헤드램프점등회로에 있어서, 상기 릴레이스위치 K1 및 K2로 연결되는 전원공급라인 중간에 릴레이 스위치 SW2를 접속하고, 이 릴레이 스위치가 엔진점화키스위치 SW1의 오프시 차량 휠 스피드 센서(5)의 출력펄스가 없는 것에 반응하여 전자제어장치(10)에서 발생하는 릴레이 구동신호에 의해 오프되게 한 것을 특징으로 한다. 본 발명에 의하면, 엔진 시동이 꺼지고 나서 헤드램프를 켜놓고 내리더라도 헤드램프가 일정시간후 자동으로 오프됨으로써 자동차의 배터리가 방전될 우려를 제거할 수 있는 이점이 있다.The present invention relates to a vehicle headlamp auto-off device, which is connected in parallel to the power supply line of the vehicle battery (B) via relay switches K1 and K2 and connected by the operation of SW3 of the headlamp switch to the left and right heads of the vehicle. In the headlamp lighting circuit for supplying power to the lamps L1 and L2, a relay switch SW2 is connected in the middle of a power supply line connected to the relay switches K1 and K2, and the relay switch is turned off of the engine ignition key switch SW1. In response to the absence of the output pulse of the vehicle wheel speed sensor 5, it is characterized in that it is turned off by the relay drive signal generated by the electronic controller 10. According to the present invention, even if the headlamp is turned off after the engine is turned off, the headlamp is automatically turned off after a certain time, thereby eliminating the risk of the battery of the vehicle being discharged.
