Abstract
A control device of an automatic transmission that controls the automatic transmission including a friction engagement element capable of continuously changing a transmission torque includes: a first heat load estimation unit configured to estimate a heat load state in the friction engagement element based on an indication value of the transmission torque; and an estimation stop unit configured to stop the estimation of the heat load state based on a state where the indication value of the transmission torque differs from an actual value of the transmission torque actually transmitted by the friction engagement element.
