To accurately suppress torque variation generated on an engine.SOLUTION: An HV-ECU executes processing including the steps of: setting a standby time until generating correction torque (S204) in a case where an F/C in-execution flag being switched from On to Off (Yes for S200), with a correction permissible determination condition established (Yes for S202); setting a magnitude of the correction torque (S206); and controlling a PCU so that the set correction torque is generated (S210) in a case where the standby time has elapsed (Yes for S208).SELECTED DRAWING: Figure 10 【課題】エンジンにおいて発生するトルク変動を精度高く抑制する。【解決手段】ＨＶ−ＥＣＵは、Ｆ／Ｃ実行中フラグがオン状態からオフ状態に切り替わり（Ｓ２００にてＹＥＳ）、かつ、補正許可判定条件が成立すると（Ｓ２０２にてＹＥＳ）、補正トルクを発生させるまでの待機時間を設定するステップ（Ｓ２０４）と、補正トルクの大きさを設定するステップ（Ｓ２０６）と、待機時間が経過すると（Ｓ２０８にてＹＥＳ）、設定した補正トルクが生じるようにＰＣＵを制御するステップ（Ｓ２１０）とを含む、処理を実行する。【選択図】図１０
