To provide a control device of hybrid vehicle that can extend a distance of evacuation driving powered only by a motor when an anomaly is detected in an engine.SOLUTION: When an engine 12 is abnormal, evacuation driving powered by a motor MG is executed, but during evacuation driving, the driving state of an electric oil pump 58 is controlled according to the MG rotation speed Nm of the motor MG, for example, when the MG rotation speed Nm of the motor MG is high and a sufficient amount of oil OIL is discharged from a mechanical oil pump 34, the power consumption of the electric oil pump 58 can be suppressed by stopping the electric oil pump 58. As a result, the reduction of a charge state value SOC of a battery 54 can be suppressed and an evacuation-driving-possible distance can be extended.SELECTED DRAWING: Figure 1 【課題】エンジンに異常が検出されたとき、電動機のみを動力源とする退避走行の距離を延ばすことができるハイブリッド車両の制御装置を提供する。【解決手段】エンジン１２の異常時には電動機ＭＧの動力による退避走行が実行されるが、退避走行中は電動機ＭＧのＭＧ回転速度Ｎmに応じて電動オイルポンプ５８の駆動状態が制御される為、例えば電動機ＭＧのＭＧ回転速度Ｎmが高く機械式オイルポンプ３４から十分な量のオイルOILが吐出されているときには、電動オイルポンプ５８を停止させることで、電動オイルポンプ５８による電力消費量を抑えることができる。その結果、バッテリ５４の充電状態値ＳＯＣの減りが抑えられ、退避走行可能な距離を延ばすことができる。【選択図】図１
