    摘要： In lock-up capacity control apparatus and method for a torque converter, the torque converter is caused to have a converter state in which a relative revolution between input and output elements of the torque converter is free of limitation in a case where a lock-up capacity (L/Uprso) during a no-load state is equal to or larger than a shock determining lock-up capacity (α), during an acceleration slip lock up in which the lock-up capacity of the torque converter is augmented by means of a time series control which accords with a load state of an engine, and the torque converter is caused to be oriented toward a lock-up state in which the relative revolution is zeroed by continuing an augmentation of the lock-up capacity by means of the time series control in a case where the lock-up capacity during the no-load state is smaller than the shock determining lock-up capacity.

    摘要： A lock-up clutch control device which controls a lock-up clutch provided in a torque converter installed between an engine and a transmission, is disclosed. The lock-up clutch control device changes over between a converter state and a lock-up state of the torque converter according to a differential pressure command value (LUprs) relating to a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a differential pressure generating device (7, 8) which generates the differential pressure supplied to the lock-up clutch; input torque detection means (2, 14, 15) which detects an input torque (Te) to the torque converter; and a controller (1). The controller (1) is programmed to compute a real differential pressure (P_lu) based on the detected input torque (Te) upon completion of the engagement of the lock-up clutch; compute a learning value (P_learn(Tai)) relating to a differential pressure deviation, based on the difference between the computed real differential pressure (P_lu) and differential pressure command value (P_ref) upon completion of the engagement of the lock-up clutch, and store the learning value (P_learn(Tai)); correct a present differential pressure command value (LUprs_slp) based on the learning value (P_learn(Tai)); and send the corrected differential pressure command value (LUprs) to the differential pressure generating device (7, 8).

    摘要： A lock-up clutch control device controls a lock-up clutch provided in a torque converter mounted between an engine and a transmission of a vehicle. The lock-up clutch control device switches between a converter state and a lock-up state by controlling a differential pressure supplied to the lock-up clutch. The lock-up clutch control device has a controller and a differential pressure generator for generating the differential pressure in response to a differential pressure command value. The controller calculates a first differential pressure command value which decreases at a predetermined rate, after the vehicle speed becomes a first predetermined speed; sets the differential pressure command value to a second differential pressure command value, before the vehicle speed becomes a second predetermined speed; and sets the differential pressure command value to a value at which the lock-up clutch is immediately released, when the vehicle speed becomes the second predetermined speed.

    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 the state of the torque converter (5) between a converter state and a lock-up state by controlling a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a sensor (13, 19) for detecting a rise of a vehicle speed; a differential pressure generator (7, 8) which generates the differential pressure supplied to the lock-up clutch; and a controller (1). The controller is programmed to command the differential pressure generator (7, 8) to lock the lock-up clutch (6) when the vehicle speed exceeds a predetermined low vehicle speed (V1), after the vehicle is started; subsequently monitor the rise of the vehicle speed; and command the differential pressure generator (7, 8) to unlock the lock-up clutch when the monitored rise of the vehicle speed is lower than a preset value (Vss/αs).

    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).
