Abstract
본 발명에 따른 제동등 고장 검출장치는 브레이크 페달을 밟으면 브레이크 스위치(SW1)가 접촉되어 제동등(Lamp2)이 점등되도록 하는 제동등장치에 있어서, 상기 브레이크 스위치(SW1)가 접촉될 때 상기 제동등(Lamp2)의 상태에 따라 흐르는 전류의 크기가 변하는 것을 검출하는 전류검출저항(R1); 상기 전류검출저항(R1)에 의해 강하된 전압을 소정의 기준전압과 비교하는 비교기(IC1); 및 상기 비교기(IC1)의 출력에 따라 온, 오프되는 스위칭수단으로 구성되어 있다. 따라서 제동등이 고장이 난 경우 이를 계기판등에 표시하여 운전자에게 알려주므로써 신속하게 제동등을 교환하여 충돌사고를 예방할 수 있는 효과가 있다.The brake lamp failure detecting device according to the present invention is a brake lamp device in which the brake switch SW1 is brought into contact with the brake switch SW1 when the brake pedal is pressed, and the brake lamp SW1 is turned on when the brake switch SW1 is in contact. A current detection resistor R1 for detecting that the magnitude of the current flowing according to the state changes; A comparator (IC1) for comparing the voltage dropped by the current detection resistor (R1) with a predetermined reference voltage; And switching means turned on and off in accordance with the output of the comparator IC1. Therefore, when the brake light is broken, it is displayed on the instrument panel to inform the driver, so it is possible to replace the brake light quickly to prevent a crash accident.
