To suppress consumption of engine oil.SOLUTION: An engine control apparatus is used for a hybrid vehicle that includes an engine, a first motor, a planetary gear connected to the engine, first motor, and a drive shaft connected to an axle, a second motor for inputting and outputting power to and from the drive shaft, and a battery for exchanging power with the first and second motors, and causes the drive shaft to exert braking force through motoring by the first motor with the engine cutoff of fuel injection and regenerative driving of the second motor, during a downhill travel in which to travel on a downhill with accelerator-off and brake-off. In the case of being estimated that a charging ratio of the battery is equal to or higher than a given ratio thereof during the downhill travel, the control apparatus increases a throttle opening degree as compared to the case of being estimated that the charging ratio is less than the given ratio during the downhill travel.SELECTED DRAWING: Figure 3

    【課題】エンジンオイルの消費を抑制する。【解決手段】エンジンと、第1モータと、エンジンと第1モータと車軸に連結された駆動軸とに接続されたプラネタリギヤと、駆動軸に動力を入出力する第2モータと、第1、第2モータと電力をやりとりするバッテリと、を備え、アクセルオフ且つブレーキオフで降坂路を走行する降坂走行時には、燃料噴射を停止した状態のエンジンの第1モータによるモータリングと第2モータの回生駆動とによって駆動軸に制動力を作用させるハイブリッド車のエンジンを制御するエンジン制御装置であって、降坂走行時にバッテリの蓄電割合がバッテリの所定割合以上になると推定されるときには、降坂走行時に蓄電割合が所定割合未満であると推定されるときに比して、スロットル開度を大きくする。【選択図】図3
