摘要： A torque converter having an engine-driven pump impeller fastened to an input shell and a fluid-driven turbine runner mounted on an output shaft is equipped with a fluid-operated lockup clutch for providing a direct mechanical drive between the input shell and the output shell. The lockup clutch is maintained in a slipping engagement condition in an intermediate speed range. This slipping engagement is controlled by a variable fluid passage whose opening size is determined by an axial position of the turbine runner relative to the output shaft. The turbine runner is rotatable and axially movable relative to the output shaft. The turbine runner and the output shaft have, respectively, flanges which rotates side by side. There are formed, between the flanges, a plurality of pockets which are circumferentially arranged. Each pocket has contoured surfaces, and confines a ball. Each set of the ball and pocket is so formed as to control the opening size of the variable fluid passage by causing the turbine runner to move axially when the turbine runner rotate relative to the output shaft.

摘要： A fuel cut-off control can prolong a period of time in which the engine speed is maintained at a range suitable for performing fuel cut-off and shorten a period of time in which the engine speed is in a fuel recovery range to minimize fuel consumption during engine deceleration. In a fuel cut-off control system in a fuel injection internal combustion engine with an automatic transmission, the fuel cut-off control system is responsive to a brake switch signal and an engine speed signal having a value above a fuel recovery threshold to decrease the value of a fuel cut-off threshold to again perform the fuel cut-off even in the normal fuel recovery range. Down shifting of a transmission gear is performed to increase engine speed to a level beyond the fuel cut-off threshold to prolong the fuel cut-off period.

摘要： In gear-shift control performed during normal travelling, a drive frequency of each solenoid valve is set to a higher one to suppress fluctuations or changes of a quantity or speed of a flow of a hydraulic oil concerned when the solenoid current is turned on/off to suppress fluctuations of the output hydraulic pressure. In start selection, the drive frequency of the solenoid valve is set to a lower one to reduce the number of times a plunger and a ball hit each other within the solenoid valve to reduce a sound produced by the operation of the solenoid.

摘要： During a shifting operation that a first engaging element is changed from an engaged state to a disengaged state, a fail-safe valve is used to forcibly drain a first engaging-element pressure from the first engaging element by using a second engaging-element pressure applied to a second engaging element brought into an engaging state from a releasing state. The fail-safe valve includes a spool and uses the second engaging-element pressure acting on the spool in one axial direction and an opposing pressure acting on the spool in the opposing direction as operating signal pressures. The fail-safe valve is switchable to a drain position, when the second engaging-element pressure is regulated toward a specified fail-safe valve operating point pressure higher than a maximum pressure value of the second engaging-element pressure regulated during the shifting operation and lower than a maximum possible engaging-element pressure.

摘要： An anti-creep control apparatus of an automatic transmission has a forward clutch control section which controls the hydraulic pressure of a forward clutch by slipping the forward clutch when the automatic transmission is set in a drive range and the vehicle is stopped while an engine is operating. The anti-creep control apparatus controls an hydraulic pressure of the forward clutch to be held or increased by a predetermined value when a relative rotation of the forward clutch is detected during the anti-creep control. The controlled hydraulic pressure is set as a lower limit value of the forward clutch hydraulic pressure in a present anti-creep control.
