In a control apparatus and a control method for a vehicle automatic transmission in which a plurality of gears with different speed ratios are achieved by selectively engaging a plurality of friction engagement devices and a one-way clutch, if an acceleration request is made in the case where the one-way clutch is in an idling state when a first predetermined gear is to be achieved by engaging the one-way clutch, a pre-synchronization control is executed to transmit torque through a predetermined friction engagement device used to achieve a second predetermined gear at which the one-way clutch is maintained in an idling state, and to continue to change a rotational direction of the one-way clutch toward a rotational direction in which the one-way clutch is brought to a synchronized state, according to the acceleration request. |
