Abstract

본 발명은 자동차 전구 끊어짐 경고장치에 관한 것이다. 본 발명에 따르면 차내 각 램프스위치에 관련된 전구조합의 각 전구 필라멘트 양단에 저항을 병렬연결하고, 전자제어장치에 각 램프스위치의 온(ON)시 해당 전구조합회로에 흐르는 전류를 검출하여 램프스위치 단위별 전구조합의 합성저항값을 산출하고, ROM에 미리기억시킨 해당 전구조합의 합성저항값과 비교하여 같지 않을 때 경고등을 점등시킴으로써 운전자가 전구 끊어짐 상태를 인지하고 즉 전구를 교환할 수 있는 등 자동차 안전운행에 지대한 효과를 나타낸다.The present invention relates to an automobile light bulb break warning device. According to the present invention, a resistor is connected in parallel to both ends of each bulb filament of the bulb combination related to each lamp switch in the vehicle, and when the lamp switch unit is turned on to the electronic control device, the current flowing through the bulb assembly circuit is detected and the lamp switch unit By calculating the combined resistance value of each bulb combination and comparing the combined resistance value of the corresponding bulb combination previously stored in the ROM, the driver lights up a warning light when it is not the same, so that the driver can recognize the disconnection state, that is, replace the bulb. It has a great effect on safe operation.
