Abstract

A control apparatus for a stepped automatic transmission in which one of a plurality of shift speeds is established by selectively engaging a plurality of frictional engagement elements, the stepped automatic transmission mounted on a vehicle, the control apparatus includes: an electronic control unit configured to perform a control of prohibiting a plurality of shift that is transitioning from an upshift speed change to a downshift speed change, for a predetermined period, when a downshift speed change requirement is requested by an occurrence of an accelerator depression operation during an inertia phase of the upshift speed change in a driven state of a vehicle.
