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.
