Abstract

When a power-on downshift via an intermediate shift stage accompanied by input switching control is required and a predetermined shift stage is a shift stage lower than the intermediate shift stage, an electronic control unit performs torque phase control in a torque phase control time shorter than the torque phase control time that is set when the predetermined shift stage is a shift stage higher than the intermediate shift stage. Accordingly, it is possible to complete disengagement of a disengagement-side element early and to suppress a rapid increase of an input shaft rotation speed due to a clutch torque remaining.
