Abstract

본 발명은 야간주행시에 신호대기나 정차에 의해 빈번하게 점등시키거나 소등시키는 헤드램프의 온/오프조작을 자동으로 할 수 있는 자동차의 헤드램프 조사각 제어장치를 제공하기 위하여 자동차에 설치되는 복수개의 헤드램프(LP1)(LP2)가 릴레이(RY)의 출력단자에 접속되어 있고, 그 릴레이(RY)의 제어단자에는 상기 헤드램프(LP1)(LP2)를 온/오프 제어하는 제1헤드램프 스위치(SW1)가 접속되어 있는 자동차의 헤드램프 제어장치에 있어서, 상기 제1헤드램프 스위치(SW1)와 컬렉터 단자가 직렬로 접속되는 파워 트랜지스터(TR)와, 자동차의 차속센서(S)로부터 출력되는 디지탈적인 차속시그널을 입력받아 그 차속시그널을 아날로그신호로 변환하여 출력단을 통해 상기 파아워트랜지스터(TR)의 베이스 단자에 출력하는 D/A 컨버터(40)로 구성한 것이다.The present invention provides a headlamp irradiation angle control device for a vehicle capable of automatically turning on / off an operation of a headlamp that is frequently turned on or off by a signal wait or a stop when driving at night. A lamp LP1 (LP2) is connected to the output terminal of the relay RY, and a control terminal of the relay RY has a first head lamp switch for controlling on / off of the head lamp LP1 LP2. In the headlamp control apparatus of a vehicle to which SW1 is connected, the first headlamp switch SW1 and the collector terminal are connected in series with a power transistor TR and a digital output from the vehicle speed sensor S. The D / A converter 40 converts the vehicle speed signal into an analog signal and outputs the vehicle speed signal to the base terminal of the power transistor TR through an output terminal.
