Abstract
A control device of a vehicle drive device includes an engine having a supercharger and an automatic transmission outputting power of the engine to drive wheels. When an upshift of the automatic transmission is performed by executing an acceleration operation, if a progress status of a supercharging pressure increase in a supercharger pressure increasing process by the supercharger is a status in an initial period of the increasing process, a supercharging pressure increase degree before start of an inertia phase of the upshift is made smaller than a supercharging pressure increase degree after a predetermined timing subsequent to the start of the inertia phase, while if the progress status of the supercharging pressure increase is a status in an ending period of the increasing process, the supercharging pressure increase degree before the start of the inertia phase is made larger than the supercharging pressure increase degree after the predetermined timing.
