Abstract
A control device for an automatic transmission includes: a transmission gear ratio control section configured to control the transmission gear ratio so that a rotation speed of the output element rapidly becomes closer to a rotation speed of the internal combustion engine, a first engagement control section configured to perform a first engagement control to be brought to the full engagement state after the rotation of the internal combustion engine is increased in the slip engagement state while a torque transmission capacity of the lockup clutch is increased when the lockup clutch is switched through the slip engagement state to the full engagement state by an ON operation of an accelerator of the vehicle, the transmission gear ratio control being prohibited during the first engagement control by the first engagement control section.
