发明名称 CONTROL APPARATUS FOR AUTOMATIC TRANSMISSION
摘要 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.
