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 selecting valve is provided, which is switched by different signals sent out when the vehicle is stopped or when the vehicle is to start to move. The selecting valve is connected to a hydraulic servo unit for a forward clutch which is engaged to transmit torque when the vehicle is to move forward, and is supplied with line pressure and a control pressure provided by an electronically operated regulating valve, such as an electronically controlled throttle valve. The regulated control pressure from the electronically operated regulating valve is supplied to the hydraulic servo unit for the forward clutch when the vehicle is stopped, while line pressure is supplied when the vehicle is to move, thus preventing creeping and shift shock at starts. Since the selecting valve is provided with a port leading to the hydraulic servo unit for a brake which restricts vehicle movement, the brake can be applied when the vehicle is stopped and released when moved, thus providing hill-holding capability.

摘要： A hydraulic control apparatus for controlling a hydraulically operated automatic transmission, having a speed sensor for detecting the speed of a rotary member which changes due to a shifting action of a frictionally coupling device. The apparatus includes a device for determining, based on the detected speed of the rotary member, that the shifting action of the coupling device is completed, and a device which is operated in the event of a failure of the speed sensor, for determining that the shifting action of the coupling device is completed when a time which has passed after the moment at which the need to effect the shifting action was determined or at which a shifting command to initiate the shifting action was generated exceeds a predetermined time interval. Upon determination of the completion of the shifting action, an electronic device terminates an operation to control the back pressure of an accumulator for adjusting the fluid pressure applied to the coupling device.

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.

摘要： Vehicular drive system which is small-sized and/or improved in its fuel economy.A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.

摘要： When a sub transmission mechanism is switched to the LO-side gear stage, a hybrid control unit executes a control operation such that vehicle speed does not exceed limit vehicle speed determined in advance in accordance with the transmission gear ratio of LO-side gear stage. Specifically, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator, so that rotation speed of the second motor generator does not exceed tolerable rotation speed. Further, the hybrid control unit reduces at least one of the driving torque generated by the engine and the second motor generator when any of temperatures respectively detected by temperature sensors exceed corresponding upper limit temperatures.
