Claims (5)
- 운전자가 가속페달을 밟아 현재보다 하위의 변속단으로 변속이 이루어지는 파워온 다운쉬프트가 개시되었는지를 판단하는 변속개시판단단계(S10)와;
파워온 다운쉬프트가 개시된 경우, 엔진회전수가 변화하는 실변속구간 내에서 해방측클러치를 제어하기 위한 TS 커브특성에 따른 기본제어토크를 토크옵저버에 의해 계산된 옵저버토크에 의해 보정하여 해방측클러치 제어토크로 산출하는 토크보정단계(S40);를 포함하되,
상기 토크보정단계(S40) 이전에는 실변속구간에 진입하였는지를 판단하기 위하여 엔진회전수와 해방측 입력축의 회전수 차이가 소정의 제1기준회전수를 초과하는지를 판단하여, 초과한 경우에만 상기 토크보정단계(S40)로 진입하도록 하는 실변속진입판단단계(S20);
를 더 구비한 것을 특징으로 하는 DCT차량의 클러치토크 제어방법. - 삭제
- 청구항 1에 있어서,
상기 실변속진입판단단계(S20) 이후 상기 토크보정단계(S40) 이전에는, 상기 기본제어토크와 상기 옵저버토크의 차이가 기준토크값 미만인 경우에만 상기 토크보정단계(S40)로 진입하도록 하여 변속제어의 안정성을 확보하는 안정성확보단계(S30)를 더 포함하여 구성된 것
을 특징으로 하는 DCT차량의 클러치토크 제어방법. - 청구항 1에 있어서,
상기 토크보정단계(S40)에서, 상기 해방측클러치 제어토크는 상기 TS 커브특성에 따른 기본제어토크에서 토크옵저버에서 계산된 옵저버토크를 뺀 값을 독립변수로 하는 함수관계에 의해 정해지는 보정값을 상기 기본제어토크에 가감연산하여 산출하는 것
을 특징으로 하는 DCT차량의 클러치토크 제어방법. - 청구항 1에 있어서,
상기 토크보정단계(S40)를 실변속구간 내에서만 수행하도록 하기 위하여, 상기 토크보정단계(S40)를 수행하면서, 실변속이 완료되었는지를 확인하기 위하여, 엔진회전수와 결합측입력축 회전수의 차이가 소정의 제2기준회전수 미만이 되는지를 반복적으로 판단하여, 미만이 되는 경우 상기 토크보정단계(S40)를 종료하도록 하는 실변속종료판단단계(S50)를 더 구비한 것
을 특징으로 하는 DCT차량의 클러치토크 제어방법.
