Abstract

본 발명은 저속 변속시의 원웨이 클러치 계합 충격을 경감하기 위한 엔진 출력 저하 제어를, 항상 확실하게 실제의 변속 동작에 대하여 알맞은 타이밍으로 행하게 하기 위한 것이다.The present invention is to ensure that the engine output reduction control for alleviating the one-way clutch engagement shock at low speed shifting is always performed at a proper timing with respect to the actual shifting operation.

본 발명의 자동 변속기(2)는 컨트롤러(9)에 의해 솔레노이드(6, 7)를 통하여 변속 제어되고, 엔진(1)은 컨트롤러(12)에 의해 제어된다. 컨트롤러(12)는 원웨이 클러치의 계합충격를 수반하는 저속 변속시, 신호(S)를 받아서 변속기 출력 회전수(No)와 후속기어비(Gi)와의 승수를 엔진 회전수(Ne)로 나누어서 얻어지는 회전비(No×Gi/Ne)가 설정치로 저하했을 때에, 상기의 계합 충격을 경감하기 위한 엔진 출력 저하 제어를 개시시키고, 이 순간부터 설정시간이 경과했을 때에 당해 엔진 출력 저하 제어를 종료시킨다.The automatic transmission 2 of the present invention is controlled by the controller 9 via the solenoids 6 and 7, and the engine 1 is controlled by the controller 12. The controller 12 receives a signal S and receives a signal S at a low speed shift with an engagement shock of the one-way clutch, thereby obtaining a rotation ratio obtained by dividing the multiplier of the transmission output speed No and the subsequent gear ratio Gi by the engine speed Ne. When No * Gi / Ne) falls to the set value, engine output reduction control for reducing the engagement shock is started, and when the set time elapses from this moment, the engine output reduction control is terminated.
