When it is determined to perform nth to (n+1)th coast downshift during nth to (n+1)th power-off upshift, an ECU starts increasing control to increase the hydraulic pressure of an engage-side element A in a predetermined mode and maintains the hydraulic pressure of a release-side element B at a value at which the increasing control is started until a predetermined period of time elapses from when the start of the increasing control. When a turbine rotational speed does not increase even after the predetermined period of time has elapsed, as the turbine rotational speed decreases below a value lower by a predetermined value than a synchronous rotational speed in the (n+1)th gear, the ECU executes feedback control over the hydraulic pressure of the element B so that the turbine rotational speed becomes the value lower by the predetermined value than the synchronous rotational speed in the (n+1)th gear. |
