    摘要： An accumulator back pressure control device for an automatic transmission, the accumulator back pressure is regulated when a shift valve is switched. For example, when shifting up from the first to the second speed, when the second brake starts to engage by switching of the shift valve, rotation speed of the input side varies by the change of the output torque of a trans­mission gear mechanism. By detecting the rotation change by a sensor, the pressure control valve (linear solenoid) is control­led by signals from a control unit so that the control pressure from the pressure control valve is controlled at required moment. By this, for example, a control valve, by the change of hydraulic pressure at the control pressure port, regulates the pressure of oil source (line pressure port) and applies such regulated pressure to the back pressure chamber of the B2 accumulator to change the back pressure of the accumulator. When shifting from the second to the third speed, the back pressure of the C2 accumulator is controlled, and when shifting from the third to the fourth speed, the back pressure of the B0 accumulator is controlled. When down shifting, the operations are performed in same manner as the above.

    摘要： A method is provided for the control of servo hydraulic pressure in an automatic transmission. Servo hydraulic pressure is adapted to engage or release first and second frictional engagement elements arranged in such a relationship that upon shifting from a particular speed stage to another, one of the first and second frictional engagement elements is released while the other is engaged. The servo hydraulic pressure is linearly lowered in a torque phase during a shift so that the servo hydraulic pressure on a side of the frictional engagement element to be released by using as an input the servo hydraulic pressure on a side of the frictional engagement element to be engaged is maintained in conformity with an inversely proportional relationship between engaging pressure and drain pressure.

    摘要： A controller (10) for a hybrid vehicle (HV) idles first an internal combustion engine (ICE; 12) when it is predicted that a load on the HV or a motor (14) will increase, and thereafter switches to a travelling mode in which the ICE (12) is used. Based on output of a vehicle weight sensor (62), a gradient sensor (64), a towing sensor (68), a start/power mode switch (60) and other on-board sensors or switches, it is predicted that a load on the HV or the motor (14) will increase. Otherwise, based on information obtained from a navigation system (66) or from another vehicle to be towed, it is predicted that a load on the HV or the motor (14) will increase. Based on a difference of output between an open air temperature sensor (70) and a cabin temperature sensor (72), a load on an on-board appliance (e.g., 50) is detected, and based on the detected load, it is predicted that a load on the HV or the motor (14) will increase. Thus, a delay in following the ICE (12) in response to the switching of travelling modes can be decreased or remedied.
