摘要： An output power of the internal combustion engine (1) is transmitted to a drive wheel via a torque converter (2B) having a pump impeller and a turbine runner. A lockup clutch (2C) directly connects the pump impeller and the turbine runner during a coast running of a vehicle. When the accelerator pedal is slightly depressed during a coast running of a vehicle in a fuel cut-off state, the lockup clutch (2C) disengages. In addition, fuel recovery of the internal combustion engine (1) is suppressed until the engaging pressure of the lockup clutch (2C) decreases, thereby preventing a vehicle speed change caused by an output power increase of the internal combustion engine (1) before the lockup clutch (2C) substantially disengages.

摘要： This invention is a lock-up clutch control device for an automatic transmission, comprising lock-up clutch control means for controlling a slip amount of the lock-up clutch to a target slip amount. When a variation rate in a required load of an engine reaches or exceeds a predetermined threshold, the target slip amount is increased at a predetermined increase rate, whereupon the target slip amount, having been increased by target slip amount increasing means, is reduced at a predetermined reduction rate. At this time, the predetermined reduction rate is set to decrease as an operating condition when the variation rate of the required load reaches or exceeds the predetermined threshold approaches an operating condition in which an increase rate of a rotation speed on the automatic transmission side of a torque converter relative to an increase in the required load is low.

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).

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.
