Abstract

본 발명은 차량용 엔진 ECU의 스위칭 감지 회로에 관한 것으로서, 일반적으로 차량용 엔진 ECU의 스위칭 감지회로는 차량에 구비되는 부분들인 크랭크나 에어콘 또는 변속기 등으로 발생되는 각종상태 신호를 스위치 회로를 통하여 엔진 ECU에 입력시키므로써 엔진의 효율적인 제어를 하는데 필요한 정보를 삼고 있는데, 종래의 엔진 ECU에서 사용하고 있는 스위칭 회로에서는 엔진 ECU의 버퍼와 스위치 사이에 풀업 저항을 사용하여 상기 스위치들에서 발생되는 신호를 엔진 ECU의 CPU로 보내는 회로 방식을 사용하여 있는바, 이 방식의 풀업저항은 부피가 크고 비용부담이 크다는 문제점을 해소하기 위하여 본 발명에서 차량에 구비되는 엔진 ECU 장치의 스위칭 감지 회로에 CPU와 버퍼 및 스위치들 사이에 풀업 저항을 사용하는 회로 방식을 채용하므로써, 회로구성에 있어서의 부피의 부담을 더는 한편, 비용도 절약할 수 있는 효과를 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching detection circuit of a vehicle engine ECU. In general, the switching detection circuit of a vehicle engine ECU transmits various state signals generated by cranks, air conditioners, or transmissions, which are parts of the vehicle, to the engine ECU through a switch circuit. By inputting the information necessary for efficient control of the engine, the switching circuit used in the conventional engine ECU uses a pull-up resistor between the buffer and the switch of the engine ECU to transmit signals generated by the switches to the engine ECU. In order to solve the problem that the pull-up resistor of the method is bulky and expensive, the CPU, the buffer and the switches are provided in the switching detection circuit of the engine ECU device provided in the vehicle according to the present invention. By adopting a circuit method using a pull-up resistor in between, In addition to the burden of volume in the configuration, it also provides an effect of saving the cost.
