- 차륜에 장착된 센서를 통해 검출한 차륜속도에 기초하여 차속과 슬립률을 연산하는 단계;브레이크 페달을 밟지 않은 상태에서 감속운행시 부의 슬립이 발생되었는지를 판단하는 단계; 및상기 단계에서 부의 슬립이 발생된 경우 현재 차량의 슬립에서 설정된 임계치를 감산한 슬립에러와 그 슬립에러의 기울기에 따라 연산된 목표토오크에 따라 아이들밸브의 개도를 조절하여 엔진 토오크를 제어하는 단계를 포함하는 것을 특징으로 하는 차량의 엔진 토오크 제어방법.
- 제 1항에 있어서, 상기 엔진 토오크를 제어하는 단계는 상기 슬립에러가 양의 값을 갖고 상기 슬립에러의 기울기가 증가되면 엔진 토오크를 증가시키는 단계와, 상기 슬립에러가 양의 값을 갖고 상기 슬립에러의 기울기의 감소폭이 소정 기준치 보다 작으면 현재 엔진 토오크를 유지하는 단계와, 상기 슬립에러가 양의 값을 갖고 상기 슬립에러의 기울기의 감소폭이 소정 기준치 보다 커지면 엔진 토오크를 감소하는 단계를 포함하는 것을 특징으로 하는 차량의 엔진 토오크 제어방법.
- 제 1항에 있어서, 상기 목표토오크를 연산하는 단계는 다음의 계산식에 의해 연산되는 것을 특징으로 하는 차량의 엔진 토오크 제어방법.[계산식]목표토오크 = { Kp×슬립에러 + Kd×(슬립에러의 기울기) }여기서, Kp와 Kd는 비례상수이다.
- 제 1항에 있어서, 상기 아이들밸브는 연료 혼합비를 미세조정범위 내에서 일정 비율만큼 조절하기 위해 마련되는 것을 특징으로 하는 차량의 엔진 토오크 제어방법.
