To calculate a remaining travelling distance appropriately reflecting a remaining battery level and predicted power generation by an internal combustion engine in a vehicle that acquires electric power for a travelling amount by the supply of electric power from a battery and the supply of electric power generated by the power generation using an internal combustion engine.SOLUTION: A remaining travelling distance calculation device includes reference remaining power calculation means 1 for calculating a reference remaining power amount W on the basis of a remaining battery power amount WB of a battery B and a remaining engine power amount WE that can be generated by an engine E and a generator G using remaining fuel in a fuel tank T. The reference remaining power amount W is obtained as a weighted average of the remaining battery power amount WB and the remaining engine power amount WE. When the remaining battery power amount WB is larger than a predetermined threshold S, the weight XB of the remaining battery power amount WB is set to be large, and when the remaining battery power amount WB is less than the predetermined threshold S, the weight XE of the remaining engine power amount WE is set to be large. The remaining travelling distance calculation means calculates a remaining travelling distance by dividing the reference remaining power amount W by a reference power consumption rate E calculated by reference power consumption rate calculation means 2.SELECTED DRAWING: Figure 1
【課題】 バッテリからの電力供給と内燃機関を用いた発電により生成された電力の供給で走行量電力を得る車両において、バッテリ残量と内燃機関による発電見込みを適切に反映した残走行可能距離を算出し得るようにする。【解決手段】 バッテリBのバッテリ電力残量WBと、燃料タンクTの燃料残量を用いてエンジンEと発電機Gにより発電可能なエンジン電力残量WEに基づいて、基準電力残量Wを算出する基準電力残量算出手段1を備える。基準電力残量Wは、バッテリ電力残量WBとエンジン電力残量WEの加重平均として求められる。バッテリ電力残量WBが所定閾値S以上の場合には、バッテリ電力残量WBの重みXBが大きく設定され、バッテリ電力残量WBが所定閾値S未満の場合には、エンジン電力残量WEの重みXEが大きく設定される。残走行可能距離算出手段は、基準電力残量Wを、基準電費算出手段2により算出された基準電費Eで除することにより、残走行可能距離を算出する。【選択図】 図1
