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： 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 control system for a continuously variable automatic transmission for an automotive vehicle, includes a throttle opening sensor that detects a throttle opening, and a controller that executes a change-speed control in a normal mode in which a desired transmission input speed is determined based on operating conditions of the vehicle and a desired transmission ratio is determined based on the desired transmission input speed when the throttle opening is less than a first value, and that executes the change-speed control in a linear mode in which the desired transmission ratio is fixed to a second value when the throttle opening is greater than or equal to the first value. The second value is set based on the desired transmission ratio used in the normal mode prior to switching to the linear mode.

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).
