摘要： In an apparatus (10) for controlling an automatic transmission (1) for a vehicle in which, at the time of gear engagement due to changing over from a reverse range or a neutral range to a forward range, a speed-change stage of the automatic transmission is shifted down to a low-speed stage after once setting it to a predetermined high-speed stage (G2). The apparatus has a detector (14,15) for detecting an amount of slippage of high-speed stage engaging elements (C2) which establish the high-speed stage and a control device for controlling to shift down, at the time of gear engagement, to the low-speed stage (G1) after the amount of slippage of the high-speed stage engaging elements has lowered to a predetermined value or smaller.

摘要： At downshifting, hydraulic pressure of hydraulic clutch on engaging side (ON clutch pressure) is increased when an input and output speed ratio ("Gratio") has fallen below a predetermined value YGDNS. YGDNS is variably set depending on the vehicle speed and the engine temperature so that it becomes a lower value at a high vehicle speed than at a low vehicle speed, and a higher value at a low engine temperature than at a high temperature. When a downshifting command to a still lower speed stage is issued during downshifting control (when FTBD=1), a downshifting completion processing is performed in the course of the downshifting control (step in S111). Oil pressure in a hydraulic engaging element on the disengaging side QDNOFF and oil pressure in a hydraulic engaging element on the engaging side QDNON are switched to the oil pressures at the time of completion of downshifting, to thereby complete the first step downshifting control at an early time. In order to prevent unnecessary speed changing at the time of tire locking, downshifting is prohibited when deceleration of the vehicle speed has exceeded a predetermined value (when a setting of FLOCK=1 is made).

摘要： An automatic transmission includes a first speed clutch and a first speed hold clutch side by side, and a first speed hold gear shift stage is smoothly established and the responsiveness of disengagement of the first speed clutch is enhanced, particularly at low temperatures. The first speed clutch and the first speed hold clutch are provided side by side, a second clutch piston for engaging the first speed hold clutch, is installed in a relatively movable manner inside a first clutch piston for engaging the firs t speed clutch, and a check valve is provided on the first clutch piston. When a first speed hold gear shift stage is established, after the first speed clut ch has been engaged by supplying hydraulic fluid to a first clutch oil chamber, the first speed hold clutch is engaged by supplying hydraulic fluid to a second clutch oil chamber. Oil outlets are formed in a clutch housing and the hydraulic oil which discharges from the opened check valve when the first speed clutch is disengaged is rapidly discharged outside the clutch outer.

摘要： Upshifting is performed in a short time without giving rise to shocks. For that purpose, at the time of upshifting, a hydraulic pressure (QUPOFF) of a hydraulic engaging element on disengaging side is controlled such that the input and output speed ratio ("Gratio") of a transmission is decreased to, and held at, a predetermined slipping region (YG(N)S) that is lower than an engaging region (YG(N)L) - YG(N)H) to be set based on a gear ratio which is established by the engagement of the hydraulic engaging element on the disengaging side. The hydraulic pressure (QUPON) of a hydraulic engaging element on engaging side is gradually increased. When "Gratio" once falls below YG(N)L and then increases up again to YGCONOK, QUPOFF is lowered to a predetermined low pressure (QUPOFFB) at a lapse of a predetermined time (YTMUP8). Once "Gratio" > YGCONOK, QUPON is increased to a predetermined high pressure QUPONB at a lapse of a second predetermined time YTMUP3. YTMUP8 is set so as to become shorter with an increase in a vehicle speed, and YTMUP3 is set so as to become longer with an increase in the vehicle speed.
