摘要： A compact automatic transmission for a vehicle capable of preventing increase in relative rotational speed between shift elements. A planetary gear unit is provided with a sun gear to which rotation of an input shaft is input, a carrier that can be stopped from rotating, and a ring gear for outputting, to a planetary gear set, rotation that is reduced in speed relative to that of the input shaft. A clutch is connected/disconnected, the input shaft and the sun gear are appropriately connected/disconnected, and the carrier is appropriately stopped/unstopped by a brake and a one-way clutch. This prevents relative rotational speed between shift elements of the gear unit that does not participate in a shifting operation from excessively increasing. When the clutch is disposed between the input shaft and the sun gear, the torque capacity of the clutch can be reduced as compared with the case where it is disposed between the gear unit and the gear set. Therefore, the clutch can be formed into a more compact structure and the overall automatic transmission can be made more compact.

摘要： A hydraulic hill hold control system for an automatic transmission for a vehicle adapted for the purpose of hill hold, wherein the supply of hydraulic pressure to the brake is interlocked with the shifting of the hydraulic speed stage switching system so that the brake is engaged only when the gear transmission mechanism is at a certain speed stage at which the brake is in any event engaged and therefore the engagement of the brake for hill hold does not interfere with the forward driving operation of the gear transmission mechanism.

摘要： A hydraulic control system for an automatic transmission detects the rotating speed of the parts whose rotating speed varies due to shifting, and controls the transitional oil pressure applied to the frictionally engaging device in the automatic transmission so that the detected rotating speed matches the locus of the target rotating speed that said parts should follow after the shift command is outputted. Thus, the optimum shifting transitional characteristics can be obtained regardless of the inherent differences among otherwise identical vehicles which differences are created at the time of manufacturing or vary with time and vehicle use.

摘要： A vehicle includes an engine and an automatic transmission which has a fluid torque converter, a forward clutch, and a manual range setting valve. Idling control for providing anti creep control is performed by, during engine idling time while the manual range setting valve is set to a forward driving range and the vehicle is substantially stationary, reducing the engagement pressure of the forward clutch by reducing the actuating pressure provided to it. A rotational speed associated with the fluid torque converter is detected, and the actuating pressure provided to the forward clutch is controlled so that the rotational speed associated with the fluid torque converter does not drop below a certain rotational speed value. Thereby good anti creep control is provided. A system is also disclosed for performing the method.

摘要： In a system for integrally controlling an automatic transmission and an engine wherein engine torque is changed during shifting, it is detected whether or not various communication means provided for carrying out the engine torque change is in a failed state. If so, a shift parameter or parameters in the automatic transmission, such as a shift point and engagement oil pressure, are changed in a direction for securing the durability of frictionally engaging devices. When the shift point is changed, a measured value of factors for determining the shift point is corrected to substantially lower the shift point. With this arrangement, computer capacity can be decreased.

摘要： In a four wheel drive vehicle, this torque distribution device includes a friction engaging mechanism which controls drive torque distribution to the front vehicle wheels and/or to the rear vehicle wheels, and a servo device which receives an actuating hydraulic fluid pressure and which applies an engaging force to the friction engaging mechanism so as to cause it to be able to transmit torque. The engaging force for the friction engaging mechanism and the maximum torque transmission capacity thereof this provided both increase monotonically according to increase of the actuating hydraulic fluid pressure. This servo device includes first and second pistons which partially serve to define respective first and second pressure chambers, and which, when impelled by hydraulic fluid pressure in their respective first and second pressure chambers, both provide such engaging force for the friction engaging mechanism. When actuating hydraulic fluid pressure is supplied to two different combinations of the first pressure chamber and the second pressure chamber, the relationships between the magnitude of the engaging hydraulic fluid pressure and the engaging force for the friction engaging mechanism and the maximum torque transmission capacity of the friction engaging mechanism differ. The combinations may be the individual pressure chambers by themselves, or may be one of the chambers and the two of them together. A three stage specialization of this device, and the method of operation thereof, are also described.
