To provide a simple and highly efficient plug-in hybrid vehicle which is mainly used for traveling on urban roads, makes maximum use of electric power of a battery stored through plug-in charging, and efficiently utilizes the electric power generated through an engine for extension of a range.SOLUTION: A plug-in hybrid vehicle comprises: a battery which has relatively small capacity and is charged through plug-in charging; a motor which is driven with the electric power of the battery; and a power generation engine having relatively small output. The plug-in hybrid vehicle: periodically identifies residual electric power in the battery and the electric power required for traveling from a present location to a destination (a place where the same undergoes the plug-in charging next) while the same is traveling; and, when the same is at risk of having the residual electric power less than the electric power required for traveling from the present location to the destination, compensates for a deficiency in the electric power in a manner that charges the battery with the electric power generated through deceleration travel while the same is mainly coasting or the electric power generated by the engine having relatively small output while the same is stopped after coasting.SELECTED DRAWING: Figure 2
【課題】市街地走行を主目的とし、バッテリーへのプラグ充電電力を最大限生かし、かつエンジンによる発電電力を効果的に航続距離拡張に活かす簡易で高効率なプラグインハイブリッド車両の提供。【解決手段】プラグインハイブリッド車において、プラグ充電された比較的小容量のバッテリー、前記バッテリー電力で駆動されるモータ、および比較的小出力の発電用エンジンを搭載し、走行中はバッテリー残電力と、現地点から目的地点(次のプラグイン充電地点)到達に必要な電力量、を周期的に特定し、前記現地点から目的地点到達に必要な電力量が残電力で不足となる恐れがある場合は、その不足分を、惰性走行主体の減速走行あるいはその後の車両停止の間の比較的小出力のエンジンによる発電電力のバッテリーへの充電で補充する。【選択図】 図2
