To provide a residual possible travelling distance calculating device, which allows a vehicle, which can obtain electric power required for travelling by supply of electric power from a battery and by supply of electric power generated by power generation using an internal combustion engine, and to calculate a residual possible travelling distance on which a prospect of power generation by the internal combustion engine is appropriately reflected.SOLUTION: The residual possible travelling distance calculating device comprises: total electric energy calculating means 1 that calculates total electric energy, residual electric power that can be utilized for travelling a vehicle; reference electric power cost calculating means 2 that calculates a reference electric power cost as a weighted average in which respective contributions of a current electric power cost and a past electric power cost memorized as cumulative data in data memorizing means M are weighted; and residual possible travelling distance calculating means 3 that calculates a residual travelling possible distance by dividing the total electric energy by the reference electric power cost. When engine rotation speed of an engine E for power generation is limited and power generation by a power generator G is not anticipated, the contribution of the past electric power cost is weighted to be smaller, which allows the residual possible travelling distance on which a situation of travelling of the vehicle is accurately reflected to be calculated.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、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】 車両の走行に利用できる電力残量である総電力量を算出する総電力量算出手段1と、データ記憶手段Mに累積データとして記憶された現電費と過去電費の各々の寄与度を重みとした加重平均として基準電費を算出する基準電費算出手段2と、総電力を基準電費で除することにより残走行可能距離を算出する残走行可能距離算出手段3を備える。発電用のエンジンEのエンジン回転数が制限され、発電機Gによる発電が見込めない場合には、過去電費の寄与度を小さく設定することにより、残走行可能距離を算出時点での走行状況を精度よく反映したものとする。【選択図】 図1
