摘要： A condition for driving an electric oil pump is set. A turbine speed or an input speed of an automatic transmission is measured. A correction amount for a hydraulic pressure is calculated on the basis of the turbine speed obtained by reference to a relation between the turbine speed and hydraulic pressure, and a correction amount for a drive duty ratio of the electric oil pump which is required for generation of the corrected hydraulic pressure is calculated. The procedure is resumed after the procedure has been performed. The condition for driving the electric oil pump is updated on the basis of the correction amount for the drive duty ratio calculated.

摘要： An electric oil pump capable of suppressing wear of an electric oil pump used as auxiliary to a main oil pump to thereby prolong the life of the pump and avoid any need to provide a larger pump. An electric oil pump (40) is operated only for a predetermined acceptable operation time, and the engine (12) is thereafter activated to cause the mechanical oil pump (36) to supply oil pressure. This arrangement can limit successive operating time for the electric oil pump (40), suppressing wear of the electric oil pump (40) and thus prolonging its life. Provision of a larger electric oil pump (40) can also be avoided.

摘要： An oil seal member is compressed between a connecting pipe for supplying oil to an oil chamber of a hydraulic servo and the cylinder drum of the hydraulic servo. The cylinder drum has an interior oil chamber and turns through a predetermined angle upon operation of a frictional engagement element by the hydraulic servo. The end of the seal member pressed against the cylindrical drum surrounds an oil hole 73 formed in the cylindrical drum, and oil pressure is supplied to the oil chamber through an oil passage in which the seal member is mounted and through the oil hole. A recess is formed in the outer surface of the cylindrical drum around the oil hole and the end of the seal member is received in the recess. When the cylindrical member turns within the predetermined angular range, the end of the seal member is protected by the recess. As a result, the end of the seal member is not damaged and the integrity of the seal is protected.

摘要： A lockup clutch of an automatic transmission is controlled so that no shock is produced while the vehicle is running within a predetermined gear stage. The automatic transmission includes a fluid coupling; a lockup clutch provided in the fluid coupling; a shift selector for selecting a range; a vehicle speed sensor for detecting vehicle speed, and a throttle opening sensor for detecting throttle opening. A control unit determines a gear stage in accordance with the selected range, the vehicle speed and the throttle opening, decides a shift, produces a shifting output signal, decides ON or OFF for the lockup clutch in accordance with the selected range, the vehicle speed and the throttle opening, and produces a lockup ON/OFF output signal. An oil pressure circuit actuates solenoid valves in response to the shifting output signal and the lockup ON/OFF output signal of the control unit. The solenoid valves, in turn, control engagement and release of frictional engagement elements to achieve the decided gear stage and control engagement and release of the lockup clutch. The control unit includes, stored in memory, a lockup diagram set with an ON/OFF hysteresis area; a comparator for deciding whether or not the vehicle speed and the throttle opening, at the time of a shifting output signal is produced, are within the ON/OFF hysteresis area of the lockup diagram; and a lockup output signal generator for turning the lockup output ON if the vehicle speed and the throttle opening are within the ON/OFF hysteresis area when the shifting output signal is produced.

摘要： A hydraulic control for an automatic transmission is composed of a gear shift mechanism having first and second frictional engagement elements, a hydraulic control unit for the engagement elements, and an electronic control unit for the hydraulic control unit. The first element is engaged to achieve a first speed stage and the second element is engaged to achieve a second speed stage faster than and closest to the first speed stage. The hydraulic control unit has a first directional control valve for switching the feeding and discharge of hydraulic pressure between the first and second engagement elements, responsive to a first solenoid signal from the electronic control unit. A second directional control valve is adapted to be switched by a second solenoid signal from the electronic control unit to achieve a third speed stage yet faster than the second speed stage. The first engagement element has a discharge line connected to a drain line via the second directional control valve. The electronic control unit has a detector for determination of tie-up of either or both of the engagement elements, whereby upon detection of tie-up by the detector, the second solenoid signal is output to the second directional control valve.

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 one 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, engaging one frictional engagement element, is linearly lowered in a torque phase during a shift so it releases the one frictional engagement element, responsive to a rise in the servo hydraulic pressure to the frictional engagement element to be engaged, to maintain an inversely proportional relationship between the servo hydraulic pressure being raised and that being released.
