To achieve required driving force for a vehicle.SOLUTION: A control device 90 is applied to a vehicle 10 including a hydrogen-fueled engine 20, a first MG 20, a transmission device 50, and a second MG 60. A CPU 91 of the control device 90 performs: air-fuel ratio adjustment processing for adjusting target air-fuel ratio of the engine 20; and second driving process for controlling first electric motor torque so as to satisfy both of maintaining output of the engine 20 even if the target air-fuel ratio is changed and balancing the sum of engine torque and first electric motor torque with input-side load torque, and for adjusting second electric motor torque so as to satisfy required driving force for the vehicle 10.SELECTED DRAWING: Figure 1 【課題】車両に対する要求駆動力を実現できること。【解決手段】制御装置９０は、水素を燃料とするエンジン２０、第１ＭＧ２０、伝達装置５０及び第２ＭＧ６０を備える車両１０に適用される。制御装置９０のＣＰＵ９１は、エンジン２０の目標空燃比を調整する空燃比調整処理と、目標空燃比が変更されたとしても、エンジン２０の出力を保持すること、及び、エンジントルクと第１電動機トルクとの和が入力側負荷トルクと釣り合うことの双方を満たすように、第１電動機トルクを制御し、且つ車両１０に対する要求駆動力を満たすように第２電動機トルクを調整する第２駆動処理とを実行する。【選択図】図１
