    摘要: A control device for controlling a transmission device configured such that when the speed change mechanism performs switching to a shift speed with a different speed ratio, special speed change control is executed in which a disengagement hydraulic pressure, is lowered to cause a disengagement element to slip, and in which the disengagement element is maintained in a slipping state over an entire speed change process. In the case where slipping of the disengagement element is not detected within a predetermined time after the disengagement hydraulic pressure is lowered at start of the special speed change control, pressure increase correction is performed in which an engagement hydraulic pressure, which is a hydraulic pressure of hydraulic oil for an engagement element that is a friction engagement element to be engaged, is raised until slipping of the disengagement element is detected.

    摘要: A transmission configured with a speed change control unit which, when upshifting the speed in an accelerator on condition, executes an engagement control including a torque phase control after executing a filling control, which controls the hydraulic control unit in such a way that a hydraulic servo of the engagement side frictional engagement element is filled with hydraulic oil, and a standby control, which controls the hydraulic control unit in such a way that hydraulic pressure for the hydraulic servo is maintained at a preset standby pressure. A correction unit is configured to correct at least one of an execution time of the filling control and the standby pressure to an increment side when a fluctuation in a rotational acceleration of the input shaft exceeding a preset determination reference is detected after the standby 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 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: 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.
