Zusammenfassung:	To improve energy efficiency while curbing degradation of drivability.SOLUTION: An engine operation condition for starting up and stopping an engine is preliminarily determined so that an engine operation ratio when a towing mode is selected is higher than the same when an all-wheel drive mode is selected. Thus, sufficient drive force is likely to be secured when the towing mode is selected and energy efficiency is likely to be enhanced when the all-wheel drive mode is selected. That is, the engine can be started up or stopped according to whether the towing mode definitely requiring large drive force when a vehicle is started to move or accelerated or the all-wheel drive mode not always requiring large drive force is selected. Thus, a hybrid vehicle control device can improve energy efficiency while curbing degradation of drivability.SELECTED DRAWING: Figure 3 【課題】ドライバビリティーの低下を抑制しつつ、エネルギー効率を向上させる。【解決手段】エンジンを始動したり停止したりする為のエンジン作動条件が、トーイングモードの選択時は全輪駆動モードの選択時と比較してエンジンの運転比率が高くなるように予め定められているので、トーイングモードの選択時には十分な駆動力が確保され易くされ、全輪駆動モードの選択時にはエネルギー効率が向上され易くされる。つまり、発進時や加速時に確実に大きな駆動力が必要になるトーイングモードと、大きな駆動力が必ずしも必要ではない全輪駆動モードと、に応じてエンジンが始動させられたり停止させられる。よって、ドライバビリティーの低下を抑制しつつ、エネルギー効率を向上させることができる。【選択図】図３
