    摘要: A lock-up clutch control apparatus for controlling a lock-up clutch (6) provided in a torque converter (5) installed between an engine (3) and a transmission (4), is disclosed. The lock-up clutch control apparatus has a differential pressure generator (7,8) which engages, causes a slip of or disengages the lock-up clutch by adjusting the differential pressure supplied to the lock-up clutch (6); a sensor (11/15) for detecting a rotational speed of the engine; a sensor (16) for detecting an input rotational speed to the transmission; and a controller (1). The controller (1) conducts proportional integration control by using a command signal to the differential pressure generator (7,8), so that an actual slip rotational speed, which is the difference between the engine rotational speed (Np) and input rotational speed (Ni) to the transmission, becomes a target slip rotational speed (Nt). The controller is programmed to conduct integration accumulating the difference (ΔN) between the target slip rotational speed (Nt) and the actual slip rotational speed (SN); to determine whether the accumulated integrated value (I) is equal to or higher than a predetermined integration value (It); and to stop the integration when the accumulated integration value (I) is equal to or higher than the predetermined integration value (It).

    摘要: A lock-up clutch control device controls a lock-up clutch (6) provided in a torque converter (5) which is mounted between the engine (3) and transmission (4) provided in a vehicle. The lock-up clutch control device switches between a converter state and a lock-up state of the torque converter by controlling a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a sensor (13) which detects a vehicle speed; a differential pressure generator (7, 8) which generates the differential pressure supplied to the lock-up clutch in response to a differential pressure command value (Pt); and a controller (1). The controller (1) is programmed to calculate a first differential pressure command value (Pu) which decreases at a predetermined rate of change, after the detected vehicle speed becomes a first predetermined vehicle speed (Vss); calculate a second differential pressure command value (Plim) which is smaller than the first differential pressure command value; and set the differential pressure command value (Pt) for the differential pressure generator (7, 8) to the second differential pressure command value (Plim), before the detected vehicle speed becomes a second predetermined vehicle speed (Vsu) which is lower than the first predetermined vehicle speed. The controller (1) is further programmed to set the differential pressure command value (Pt) for the differential pressure generator (7, 8) to a value at which the lock-up clutch is immediately released, when the detected vehicle speed becomes the second predetermined vehicle speed (Vsu).
