Abstract: An automatic transmission control apparatus includes: a frictional engagement element; a hydraulic pressure supplying section configured to supply a hydraulic pressure to the frictional engagement element; a progression state judging section configured to judge a progression state of the engagement of the frictional engagement element; a rotational speed change rate control section configured to control the hydraulic pressure so that a change rate of a rotational speed of an input shaft of the automatic transmission becomes equal to a target change rate, from when the engagement of the frictional engagement element is started; and a rotational speed feedback control section configured to perform a feedback control of the hydraulic pressure so that the rotational speed of the input shaft of the automatic transmission becomes equal to a target rotational speed, from when the progression state judging section judges a predetermined progression state.

Abstract: A control apparatus for an automatic transmission including a hydraulic pressure control means for controlling supply of hydraulic pressure to a first friction engagement element and a second friction engagement element and discharge of hydraulic pressure from the first friction engagement element and the second friction engagement, and a discharge rate changeover control means for increasing a discharge rate value of the hydraulic pressure which is discharged from the first friction engagement element in a case where when shifting from one of operating ranges to the other thereof is selected, changeover to the other operating range is carried out before completing release of the first friction engagement element, so as to become larger than a discharge rate value of the hydraulic pressure which is discharged from the first friction engagement element before the changeover to the other operating range is carried out.
