Abstract
A control device for an automatic transmission includes: a first engagement control section configured to bring the lockup clutch to a full engagement state after a rotation of the internal combustion engine is increased in a slip engagement state while a torque transmission capacity of the lockup clutch is increased, and a second engagement control section configured to add a predetermined capacity to the increased torque transmission capacity when the torque judging section judges an increase of the output torque of the internal combustion engine in a state where a sensed rotation speed difference in the slip engagement state of the engagement state of the first engagement control is increased to be equal to or greater than a first predetermined value, and then decreased to be equal to or smaller than a second predetermined value smaller than the first predetermined value.
