Abstract
본 발명의 목적은 작동유량이 적어져서 토크 컨버터의 록업 상태를 유지하기 어렵게 되는 타성 주행 중에 록업을 금지하는 제어를 지연시켜서 진동이나 헌팅문제를 해소하는데에 있다.An object of the present invention is to solve a vibration or hunting problem by delaying a control to prohibit lockup during inertia driving, where the operating flow rate becomes difficult to maintain the lockup state of the torque converter.
본 발명은 컨트롤러(9)는, 스로틀 개방도(TH) 및 차속(V)에 따라, 솔레노이드(6, 7)를 통하여 자동변속기(2)를 변속제어하는 동시에 솔레노이드(8)를 통하여 토크 컨버텨(3)를 록업 제어한다. 컨트톨러(9)는 다시 토크 컨버터 입력 회전수(Ne)와, 차속(V) 및 기어 비로부터 구한 토크 컨버터 출력 회전수와의 차를 근거로, 타성 주행을 검지하고, 이 타성 주행중에는 컨버텨 영역으로부터 록업 영역에의 영역 이행이 있어도 토크 컨버텨(3)의 록업을 금지한다.According to the present invention, the controller 9 controls the automatic transmission 2 through the solenoids 6 and 7 according to the throttle opening degree TH and the vehicle speed V, and at the same time, converts the torque through the solenoid 8. Lock up control (3). The controller 9 detects the inertia driving again based on the difference between the torque converter input rotational speed Ne and the torque converter output rotational speed determined from the vehicle speed V and the gear ratio. Even if there is an area transition from the area to the lockup area, the lockup of the torque converter 3 is prohibited.
