摘要： A shift control apparatus that disconnects and connects respective pairs of friction engagement elements during downshift to a speed spaced apart by two or more steps through an intermediate shift speed. A shift controller controls a hydraulic pressure of a second shift release element by feedback control, and in accordance with the increase in the torque capacity of the second shift release element, also controls the torque capacity of a first shift engagement element so as to be sufficiently higher than the amount of change in the torque capacity of the second shift release element. The occurrence of adverse consequences in which a shift shock is generated is effectively suppressed because a sufficient reaction force cannot be ensured during engagement switching due to insufficient torque capacity of the first shift engagement element, and since the second shift release element cannot be appropriately feedback-controlled, difficulty in control of rotation change results.

摘要： If it is determined that a D range is in use and determined that a vehicle is stopped, neutral control means (25) commands and controls an engagement pressure of a clutch (C-1) so as to achieve a state in which a piston of the clutch (C-1) contacts a clutch drum by a biasing force of a spring, and a state in which oil fills an oil passage from a linear solenoid valve (SLC1) to a hydraulic oil chamber and fills the hydraulic oil chamber. There is thus no drag loss in the clutch (C-1) during a neutral control, and the same fuel economy as when, for example, a manual shift to the neutral range is made can be achieved during the neutral control.

摘要： A control device controlling a vehicle's automatic transmission. The automatic transmission engages first and second friction engagement elements by fluid pressure from a pump operating using motive power from the vehicle's motor when a shift position is at a reverse traveling position, places the first friction engagement element on standby at a predetermined pressure that is higher than a stroke starting pressure by which a piston stroke is started and lower than a complete engagement pressure or engages the first friction engagement at the complete engagement pressure when the shift position is at a non-traveling position, and engages a third friction engagement element as a starting shift speed when the shift position is at a forward traveling position. When the shift position is at the forward traveling position, the first friction engagement element is placed on standby at the predetermined pressure if a vehicle speed is lower than a predetermined vehicle speed, or releases the predetermined standby pressure if the vehicle speed is equal to or higher than the predetermined vehicle speed.

摘要： A shift control apparatus has first, second, third and fourth engagement elements, and a shift control processing unit engaging the first and the second engagement elements in order to realize a first shift speed, engaging the third and the fourth engagement in order to realize a second shift speed, and inhibiting an increase in torque capacity of one of the first and second engagement elements before starting of release of the second engagement element when shifting from the first to the second shift speed. During shifting from the first to the second shift speed, an increase in torque capacity of one of the first and second engagement elements is inhibited before starting of release of the second engagement element. This prevents a step-like shift shock from being caused by the slowed progression of shifting when release of the second engagement element is started.

摘要： In clutch-to-clutch upshifting, the occurrence of inertia shock is suppressed while racing of the engine is prevented. Corresponding to a first sweep control in which an engaging-side pressure sweeps up toward a target hydraulic pressure PTA, a releasing-side hydraulic pressure PB sweeps down as an initial control. When the releasing-side hydraulic pressure PB becomes a minute torque capacity [fPB(0)+PKEEP+PLS2T], a hold control, which has a very low gradient δPB, is started so that the pressure is substantially held, and, after a rotation change is started, the pressure sweeps down with a low gradient δPE2 until release.
