    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 control system for an automatic transmission, comprising: a clutch adapted to be applied when a forward running range is selected, to transmit the rotation of an engine to the transmission mechanism of a speed change unit; hydraulic servo for applying/releasing the clutch; and a control unit for controlling the oil pressure to be fed to the hydraulic servo. The control unit includes: application starting pressure detecting means for detecting an application starting pressure at the instant when the application of a clutch is started; initial application pressure setting means for setting an initial application pressure on the basis of the application starting pressure which is detected by the application starting pressure detecting means; and oil pressure adjusting means for adjusting the oil pressure to be fed to a hydraulic servo, when a change is made to a forward running range, and then raising the same gradually. The application starting pressure to be detected by the application starting pressure detecting means takes the value at which the application of the clutch is actually started, so that the initial application pressure can be properly set even if the actual oil pressure to be fed to the hydraulic servo is varied by the dispersion in the urging force of a return spring or by the dispersion in a hydraulic control system.

    摘要： An automatic transmission control apparatus has an input clutch, a hydraulic servo for the clutch, a fluid temperature detector Sn6, an engine start detector Sn2, a range shift detector Sn5, and a control device for controlling the fluid pressure supply to the hydraulic servo C-1. The control device raises the fluid pressure supply to the hydraulic servo on the basis of predetermined rising characteristics in normal operation. When it is determined that the shift has been performed for the first time since the start of the engine and it is determined that the fluid temperature is lower than a predetermined temperature, the control device rapidly raises the fluid pressure supply to the hydraulic servo up to the required engaging pressure.
