Abstract
Description
도 2 는 본 발명의 일 실시예에 따른 엔진토크 리미트 제어방법의 순서도이다.
21: 엔진토크 검출부 22: 엔진회전수 검출부
30: 변속 제어부 40: 구동부
Claims (3)
- 엔진회전수와 엔진토크를 이용하여 입력토크를 계산하는 단계;
상기 입력토크를 기 설정된 설정토크와 비교하는 단계;
상기 입력토크가 상기 설정토크를 초과하면, 상기 설정토크를 기반으로 상기 입력토크에 대한 엔진토크를 환산하는 단계; 및
상기 엔진토크를 기반으로 엔진 리미트 제어를 수행하는 단계를 포함하되,
상기 엔진토크를 환산하는 단계는 상기 입력토크가 상기 설정토크 이하가 되도록 토크 컨버터 특성값을 이용하여 상기 엔진토크를 환산하고,
상기 토크 컨버터 특성값은 상기 입력토크와 상기 설정토크의 토크 슬립량에 따른 엔진토크인 것을 특징으로 하는 엔진토크 리미트 제어방법.
