Abstract
A control apparatus for controlling an automatic transmission including a torque converter to which a driving force of an engine is input includes a specifying unit configured to specify a drag torque of a wet friction type lock-up clutch, and a transmission unit configured to transmit load information including at least the drag torque specified by the specifying unit to a control apparatus of the engine. The specifying unit specifies the drag torque of the lock-up clutch during in-gear based on a slip ratio of the torque converter before in-gear when the lock-up clutch is released.
