Zusammenfassung:	Provided is a control device for a vehicle drive device, capable of improving the drivability of a drive device for a vehicle comprising an engine with a supercharger and an automatic transmission. When increasing the supercharging pressure (Pcmout) at the end of upshifting of the automatic transmission (12) to higher than at the start of upshifting, in order to increase the engine torque (Te) at end of upshifting to greater than at the start of upshifting, the control device starts to increase the supercharging pressure (Pcmout) before completion of upshifting and progresses the gear shift operation of the automatic transmission (12), such that the supercharging pressure (Pcmout) changes to a target supercharging pressure determined by a predicted engine operation state at the end of upshifting. Accordingly, when a time delay in the increase in supercharging pressure (Pcmout) occurs, that time delay is compensated for, and the drive force request by the driver is more readily fulfilled at end of upshifting. As a result, the drivability during said upshifting is improved.
