Abstract

There is provided a control apparatus for an automatic transmission AT into which driving forces from driving sources including an engine Eng and a motor/generator MG are inputted. The control apparatus includes: a second brake B2 engaged in a D range; an engagement start determining section (steps S2→S3→S4); and a determination inhibit section (steps S2→S5→S6). The engagement start determining section determines that second brake B2 has started the engagement in a case where a load of the motor/generator MG is increased by a predetermined quantity during the revolution number control and when the D range is selected and second brake B2 in the release state is engaged. The determination inhibit section inhibits the engagement start determination in a case where a switching from an HEV mode to an EV mode occurs.
