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.

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).

摘要： A controller (5) performs open loop control of the engaging state of a lockup clutch (2) through a switching mechanism (3, 4) when a torque converter (1) transitions from a first state in which the lockup clutch (2) is disengaged to a second state in which the lockup clutch (2) is at least partially engaged. At this time, the controller (5) estimates the engine torque at the time when open loop control ends, estimates a necessary lockup capacity required for the converter (1) at the time when open loop control ends, based on the estimated engine torque, and controls the engaging state of the lockup clutch (2) through the switching mechanism (3, 4) to make the lockup capacity at the time when open loop control ends become the necessary lockup capacity.

摘要： A lock-up clutch control device which controls a lock-up clutch (6) provided in a torque converter (5) interposed between an engine (3) and a transmission (4) used with a vehicle, is disclosed. The lock-up clutch control device has a differential pressure generating device (7,8), a vehicle speed sensor (13), a throttle valve opening sensor (14), an transmission input shaft rotation speed sensor (16), engine torque detection means (2), and a controller (1). The controller (1) determines, based on the detected vehicle speed (VSP) and the detected throttle valve opening (TVO), whether or not a control region of a torque converter is a converter region wherein control is performed to disengage the lock-up clutch. When the control region of the torque converter is not the converter region, the controller (1) determines whether or not the control region of the torque converter is a slip control region wherein control is performed to make the lock-up clutch slip, based on the detected input shaft rotation speed (Npri) of the transmission and the detected engine torque (Te). When the control region of the torque converter is the slip control region, the controller commands the differential pressure generating device (7,8) to cause a slip of the lock-up clutch (6).
