Patent ID: 8725367

Claim:
A control apparatus 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, the control apparatus comprising: a pre-synchronization control portion that executes a pre-synchronization control to transmit a torque to an output shaft of the vehicle automatic transmission by semi-engaging a predetermined friction engagement device among the plurality of predetermined friction engagement devices, wherein a first predetermined gear is achieved by engaging the one-way clutch, the pre-synchronization control brings the one-way clutch into a synchronized state after maintaining the one-way clutch in an idling state, and the synchronized state is an engaged state; and a post-synchronization control portion that executes a post-synchronization control to disengage the predetermined friction engagement device, wherein if an acceleration request for accelerating a vehicle is made in a case where the one-way clutch is in the idling state when the first predetermined gear is to be achieved, the pre-synchronization control portion executes the pre-synchronization control; and when the one-way clutch is brought to the synchronized state after the pre-synchronization control is executed, the post-synchronization control portion executes the post-synchronization control.
