    摘要: First, the sleeve stroke SSt of a specific sleeve is gradually increased from "0" (after t1) in a state in which a vehicle is stopped, a transmission is in a neutral state (all sleeve strokes SSt = 0 (original position)), a clutch is in a disengaged state (clutch stroke CSt = 0 (original position)), and an engine is operating (engine rotational speed NE > 0). After that, upon determination that "the sleeve stroke SSt has reached a "predetermined value A, at which synchronization operation of a corresponding synchronization mechanism is performed," the sleeve stroke SSt is fixed to the predetermined value A, and an operation of increasing the clutch stroke CSt from "0" in a press engagement direction is started (time t2). An engagement start point CStlearn of the clutch is obtained on the basis of a change in the rotational speed Ni of an input shaft Ai of the transmission after that (time t3). Even in the case where there occurs a phenomenon in which the input shaft of the transmission slightly rotates due to rotation of the engine despite the clutch being in the disengaged state, the engagement start point of the clutch can be obtained reliably.

    摘要: The invention relates to a hydraulic control device (100) for an automatic transmission of a motor vehicle, with several shift elements (106) for shifting transmitting torque, said hydraulic control device comprising at least one first pressure adjusting device (103) and at least shutoff valve (101), said shift elements (106) comprise respectively a shift element cylinder (107) for the actuation thereof. The shutoff valve (101) is arranged between the first pressure adjusting device (103) and the respective shift element cylinder (107) and can be shifted hydraulically in two shift positions by changing the control pressure (p_S). In a first shift position, the first pressure adjusting device (103) is hydraulically connected to the shift element cylinder (107) by the shutoff valve (101) and in a second shift position, the shift element cylinder (107) can be sealingly closed by the shutoff valve (101) with respect to the remaining hydraulic control device and then also the first pressure adjusting device (103). According to the invention, the shutoff valve (101) is designed as a unlockable non-return valve and comprises a non-return valve (120) and an unlocking device (110) which can be actuated by means of the control pressure (p_S) from one of the two pressure control devices (104).
