    摘要： A lock-up clutch is arranged in parallel with a power transmission path between a pump impeller and a turbine runner of a fluid coupling arranged between the drive side and the load side, wherein the lock-up clutch changes the power transmission path. A stall capacity factor is determined using an engine speed at which the maximum engine torque on the drive side is generated, and the rotation on the drive side is transmitted to the load side by using the stall capacity factor. Therefore, optimal acceleration can be obtained by setting the stall capacity factor such that the stall rotational speed is in the vicinity of the rotational speed at which the maximum engine torque is generated. Thus, drivability can be improved by obtaining a control amount with which the vehicle speed responds as expected to the accelerator, there is no uncomfortable sensation, and fuel economy can be improved.

    摘要： In sliding engagement of a clutch plate of a lock-up clutch with a front cover of a converter housing, with a difference in rotational speed therebetween, the sum of the urging force of a coil spring and the force of a lock-up discharge hydraulic pressure in a front side chamber is greater than the force of a lock-up engagement pressure in a rear side chamber. A selector valve member, accommodated in a valve chamber of a displacement selector mechanism, therefore, brings an oil chamber between the clutch plate (first piston) and a second piston into communication with the front side chamber. The hydraulic pressure of the rear side chamber received by a rear face of the piston is higher than hydraulic pressure of the oil chamber received by a front face of the piston and, therefore, the piston is displaced forwardly into frictional contact with the clutch plate and transmission of judder to an input shaft of a speed change mechanism is thereby reduced.

    摘要： An exemplary control device includes an input torque detection unit that detects an input torque input to the input shaft; and a controller that: determines torque distribution of two of the friction engagement elements that form the shift speeds; and calculates a transmission torque of the two friction engagement elements based on the input torque and the torque distribution and sets the engagement pressure to obtain a torque capacity that can transmit the transmission torque, wherein the controller sets the engagement pressure such that slippage does not occur in the two friction engagement elements in a state where engagement of the two friction engagement elements forms the shift speeds and such that, even if an additional friction engagement element engages based on the line pressure while the two friction engagement elements are engaged, one of the three friction engagement elements is caused to slip.
