摘要： A hydraulic pressure control apparatus for a lockup clutch of a fluid transmission device. In a spool of the lockup relay valve, switching to a position on an engaging side (right half position) for engaging a lockup clutch is achieved by a signal pressure being input from a linear solenoid valve to a hydraulic oil chamber, and switching to a position on a releasing side (left half position) for releasing the lockup clutch is achieved by an urging member such as a spring force of a spring. Since the response is low with the switching by the spring force, the state of a vehicle is sensed by a sensor and, if quick release of the lockup clutch is necessary, a signal pressure from a solenoid valve is input to a hydraulic oil chamber to apply the spring force, and assists with a hydraulic pressure, thereby switching the spool to the releasing side. Accordingly, the response when the lockup relay valve is switched from the engaging side to the releasing side is enhanced.

摘要： A hydraulic control apparatus of an automatic transmission including a switching portion which, at the same time as a reverse range pressure oil passage and a discharge delay oil passage which delays an oil pressure output are connected, causes the reverse range pressure oil passage and discharge delay oil passage, by switching between the two, in order to communicate with a hydraulic servo. The switching portion causes the hydraulic servo and discharge delay oil passage to communicate when a manual valve is switched to an N range, and causes the hydraulic servo and reverse range pressure oil passage to communicate when the manual valve (MV) is switched to a D range or an R range. Because of this arrangement, it is difficult for oil, when discharged from the hydraulic servo, to drain at an R-N switching time, and it is easy for oil to drain in the D range or the like.

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.
