Abstract

본 발명은 차량 아이들스위치(idle switch)의 접점불량 경고방법에 관한 것으로, 종래의 아이들스위치(30)의 접점상태가 불량하게 되면 비동기분사가 이루어지지 않으며, 이로 인해 엔진의 부조와 출력부족현상 등 엔진의 성능저하가 발생되며, 차량에 대한 지식이 부족한 사용자는 이러한 상황에서도 상기 아이들스위치의 접점불량을 인식할 방법에 미흡하고 따라서 상기 상황하에서도 그대로 차량을 운행하거나 또는 차량의 이상유무를 감지하여도 차량정비소의 작업자는 일일이 각 부품을 점검해야 하는 문제점이 발생되었다.The present invention relates to a method of warning a contact failure of a vehicle idle switch. When a contact state of a conventional idle switch 30 becomes poor, asynchronous injection is not performed. As a result, The performance of the engine is deteriorated and the user who lacks knowledge of the vehicle is insufficient in the method of recognizing the faulty contact of the idle switch even in such a situation. Therefore, even when the vehicle is operated under the above conditions, The worker at the vehicle repair shop had to individually check each part.

이에 본 발명은 예시도면 제3도 및 제4도에서와 같이 ECU가 냉각수온, 드로틀벨브의 개도치, 흡기압력을 인식하여 상기 냉각수온이 규정값 이상이고, 드로틀 밸브의 개도치가 미소(α) 상태 이상에서 일정시간(t₁)동안 흡기압력이 아이들상태의 흡기압력(β)이하일때 일정시간 뒤에도 아이들스위치가 접점(on)되지 않은 경우 다이어그노시스단자로 출력함으로써 상기 문제점을 해소한 것이다.3 and 4, the ECU recognizes the coolant temperature, the throttle valve opening value, and the intake air pressure so that the coolant temperature is equal to or higher than a predetermined value, and the throttle valve opening value is in a smoother (?) State If more than a predetermined time (t ₁₎ when the intake air pressure is equal to or less than the intake air pressure (β) in the idle state, a predetermined time after the idle switch is not the contact (on) while in the will eliminate the problems described above by outputting a diagram gnosis terminal.

Description

How to warn the vehicle idle switch for contact failure

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 전자제어 연료분사장치의 구성도, 제2도는 드로틀보디에 장착된 드로틀센서를 나타낸 개요도.Fig. 1 is a schematic view of an electronic control fuel injection device; Fig. 2 is an outline view showing a throttle sensor mounted on a throttle body; Fig.

Claims

ECU is on water, gaedochi of the throttle valve, and to recognize the intake air pressure than the cooling water temperature is the specified value, the gaedochi the throttle valve smile (α) predetermined period of time in an abnormal state (t ₁₎ intake air pressure is in the idle state, the intake for If the idle switch is not turned on after a certain period of time under pressure (β), it outputs a warning to the diagonal terminal to warn the faulty state of the vehicle idle switch contact.
