Abstract

본 발명은 연료제어엔진(14), 마스터 마찰클러치(16), 다속기계 변속기(12) 및 마이크로 프로세서를 토대로 한 제어장치(44)를 구비한 자동기계 변속장치(10)가 장비된 차량에 대해 차량줄발상태중 엔진연료주입을 제어하는 제어방법/장치에 관한 것이다. 차량출발중 트로틀위치(THL)의 기준값(최대 연료주입의 10~20%)보다 작으면, 연료주입이 드로틀 위치를 따르고, 그렇지 않으면, 연료주입이 드로틀 위치 엔진속도(ES) 및/또는 변화비(dES/dt)클러치장치 및/또는 시간인자의 기능에 따라 제어장치에 의해 결정되는 산출량(FCALC)이다.
