A controller (20), when switching from a travel mode in which a vehicle travels with an engine clutch (EC) disengaged to a travel mode in which the vehicle travels with the engine clutch (EC) engaged, performs a preparatory speed change to reduce a rotation speed differential in the engine clutch (EC), engages the engine clutch (EC) when the rotation speed differential in the engine clutch (EC) is reduced, and then performs a completion speed change until a speed ratio required in the post-switching travel mode is obtained. The upper limit value of a shifting speed during at least one of the preparatory speed change and the completion speed change is set to a different value to the upper limit value of the shifting speed when a speed change is performed during traveling in the same travel mode.
