Abstract

본 발명은 유압 작동식 자동 변속기의 고유온 방지를 위하여 엔진 열부하가 엄격한 상태의 소정 시간 계속시에 엔진 토크를 감소시키는 토크 다운 제어를 행하는 하고, 운전자에 의한 액셀러레이터 가압을 촉진한다. 엔진(1), 토크 컨버터(3), 유압 작동식 자동 변속기(2)에 의해 파워 트레인을 구성하고, 엔진 토크 제어를 위하여 엔진 컨트롤러(8)를 설치한다, 엔진 컨트롤러(8)는 센서(9~11)로 부터 스로틀 개도(TVO), 엔진 회전수(Ne), 차속(V)이 입력되어서 소정의 제어 프로그램을 실행함으로써, 엔진 열부하의 과부하 상태가 소정 시간 계속된 경우, 엔진 토크를 감소시켜서 운전자에 다운 시프트 변속을 위하여 액셀러레이터 가압을 촉진하여 엔진 열부하가 심한 상태의 해소를 도모한다.
