Abstract

무단 변속기 변속제어의 최적화를 도모한다.
목표 변속의 달성에 최저한 필요한 일차 최소압(Ppmin)을 연산하고 블록[블록 (1)], 이차 풀리(5)와 벨트(6)의 사이에서 미끄러짐이 발생하지 않기 우하여 최저한 필요한 라인 압(Ppmin)을 연산하고 [블록(2)], 일차 풀리(40)쪽에서 미끄러짐을 발생시키지 않고, 목표 변속비를 실현할 수 있는 변속비 요구라인 압(Plratio)을 연산하고, [블록(3), (4)], 상기 Plpmin과 Plratio의 가운데 어느 것이든지 높은 관을 선택하고 [블록(5)], 선택한 라인 압(Plbase)을 엔진토크 TQENG와 변속속도 SV로부터 결정되는 과도시 라인 압(Pl add)등으로 보정하여, 최종적인 출력 라인 압(Plprs)를 구하고 [블록(6), (7), (8)], Plprs에 의하여 이차 풀리쪽 액추에이터(5a)를 제어한다. 이에 따라서, 급변속기 벨트(6)의 미끄러짐이 억제되는 등 라인 압 제어의 최적화를 도모할 수 있다.
