Abstract
The present invention is a control device for an automatic transmission, the control device being adapted to control the automatic transmission including a torque converter and a stepped transmission mechanism provided on a power transmission route from the torque converter to drive wheels, wherein while a non-driving range of the automatic transmission is selected, determination on interlock in the stepped transmission mechanism is executed on the basis of deceleration of an output shaft of the stepped transmission mechanism and a change in the torque converter.
