Description
Claims (4)
- MAT센서(14)를 통해 흡기매니폴드(12)의 온도를 감지하는 제1단계와, ECU(26)로부터 생성되는 MAT장애코드를 근거로 상기 MAT센서(14)의 고장여부를 판단하는 제2단계, 상기 제2단계의 판단결과 상기 MAT센서(14)의 고장이 감지되면 냉각수온초기치(CTSO)를 산출하는 제3단계, 기설정 시간이 경과에 따른 냉각수온치(CTSn)를 산출하는 제4단계, 상기 제4단계에서 산출된 냉각수온치(CTSn)가 기설정치 온도에 도달하는 가를 판단하는 제5단계 및, 상기 제5단계의 판단결과에 따라 설정된 상기 냉각수온치(CTS)에 상응적으로 엔진을 제어하는 제6단계를 포함하여 구성된 것을 특징으로 하는 냉각수온센서고장시 엔진제어방법.
- 제1항에 있어서, 상기 제3단계에서 상기 냉각수온초기치(CTSO)는 CTSO=MAT-Table(Runtime)-offset (①)에 기초하여 산출되는 것을 특징으로 하는 냉각수온센서고장시 엔진제어방법.
- 제2항에 있어서, 상기 Table(Runtime)은 엔진 Runtime과 반비례적으로 설정되는 것을 특징으로 하는 냉각수온센서고장시 엔진제어방법.
- 제1항에 있어서, 상기 단계 4단계에서 상기 냉각수온치(CTS)는 1분 간격으로 3.7℃씩 상승되어 산출되는 것을 특징으로 하는 냉각수온센서고장시 엔진제어방법.
