Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device that can suppress a torque variation from occurring due to response lag of a control system that changes engagement pressure of a specific engagement device even when bringing the specific engagement device into a slippery engagement state in power-on up-shift.SOLUTION: The control device, when executing power-on up-shift, brings both a specific engagement device SSC and an engagement-side engagement device into a slippery engagement state, and makes engagement pressure of the specific engagement device SSC higher than first engagement pressure ΔP1 corresponding to output torque Ten of an internal combustion engine ENG in the slippery engagement state before starting rotation change for decreasing rotation speed of a rotary electric machine MG, so as to decrease rotation speed of the rotary electric machine MG and also decrease the rotation speed of the internal combustion engine ENG.SELECTED DRAWING: Figure 7 【課題】オンアップシフトにおいて、特定係合装置を滑り係合状態にしても、特定係合装置の係合圧を変化させる制御系の応答遅れにより、トルク変動が生じることを抑制できる制御装置が求められる。【解決手段】オンアップシフトを実行する場合に、特定係合装置ＳＳＣと係合側係合装置との双方を滑り係合状態として、回転電機ＭＧの回転速度を低下させる回転変化の開始前に、特定係合装置ＳＳＣの係合圧を、滑り係合状態で内燃機関ＥＮＧの出力トルクＴｅｎに応じた第一係合圧ΔＰ１よりも高くし、回転電機ＭＧの回転速度の低下とともに、内燃機関ＥＮＧの回転速度も低下させる制御装置。【選択図】図７
