Beschreibung
Zusammenfassung:	When a release of an accelerator is detected during a shift of an automatic transmission, instead of discharging the hydraulic pressure for engagement of an engaging device of the automatic transmission immediately after the release of the accelerator is detected during a shift, the hydraulic pressure for engagement of the engaging device of the automatic transmission is gently reduced with a remaining engine torque taken into consideration, the remaining engine torque being caused by the retardation of the decrease in the throttle opening degree. In this way, the torque capacity sufficient for the remaining torque caused by the throttle opening degree control performed when the release of the accelerator is detected during the shift is kept so that a slip in the engaging device of the automatic transmission is reduced.
