Abstract

본 발명은 토크 컨버터의 록업에 있어서, 그 진행속도를 변속기의 기어 위치등, 주행 조건마다 적절한 것으로 변화시킬 수 있도록 한다.In the lock-up of the torque converter, the present invention can change the traveling speed to be appropriate for each driving condition such as the gear position of the transmission.

컴퓨터(31)는 전자 밸브(29)에 의해 제어 밸브(25)를 통하여 엔진(10) 및 변속 기구(24) 사이에 있어서의 토크 컨버터(13)의 록업 클러치(22)를 체결한다. 이때의 컴퓨터(31)는 기어 위치(G)에서 알 수 있는 변속비와 기구(42)의 출력 회전수(No)로 부터 터빈 회전수를 산출하고, 이것과 엔진 회전수(Ne)와의 차로부터 슬립량( N)을 구한다. 컴퓨터(31)는 N와 피드백 정수(K)와의 곱셈치에 따른 속도로 클러치(22)를 체결시키나, 정수(K)를 기어 위치(G)에 따라 고속 기어 위치만큼 고속으로 클러치(22)가 체결되도록 변화시켜 쇼크의 경감과 록업에 의한 연비 향상 효과를 양립시킨다.The computer 31 fastens the lockup clutch 22 of the torque converter 13 between the engine 10 and the transmission mechanism 24 via the control valve 25 by the solenoid valve 29. At this time, the computer 31 calculates the turbine speed from the speed ratio known at the gear position G and the output speed No of the mechanism 42, and slips from the difference between this and the engine speed Ne. Find the quantity (N). The computer 31 fastens the clutch 22 at a speed according to the multiplication value of N and the feedback constant K, but the clutch 22 is driven at a high speed by the high speed gear position according to the gear position G. It is changed to be tightened so that shock can be reduced and fuel efficiency can be improved by lockup.
