To alleviate a calculation load for converting a power consumption amount to a fuel consumption amount, and to accommodate a power storage amount of a battery within a prescribed range, in a hybrid vehicle.SOLUTION: An electrical value coefficient K for converting a power consumption amount to a fuel consumption amount, and a power storage amount S are calculated with an entire operation path reaching a target point from a start point as an objective zone. When the power storage amount is accommodated within a use range between an upper limit value Sup and a lower limit value Slow, the electrical value coefficient K which is calculated at this time is employed. When the power storage amount is deviated from the use range (t1), a zone up to a time point (t2) in which the power storage amount becomes maximum Smax or minimum is set as a first zone, and the electrical value coefficient K is calculated, and employed by being set as an electrical value coefficient K1 in the zone. Next, by setting a terminal point (t2) in the first zone as a start point, processing which is similar to that in the last time is performed in a zone with a target point as the terminal point. The processing is repeated until the terminal point reaches the target point, and the electrical value coefficients K1, K2, K3 ... are set in respective zones.SELECTED DRAWING: Figure 8
【課題】ハイブリッド車両において、電力消費量を燃料消費量に換算するための演算負荷を軽減し、かつバッテリの蓄電量を所定の範囲に収めることを目的とする。【解決手段】出発地点から目的地点に至る運行経路全体を対象区間として電力消費量を燃料消費量に換算するための電気価値係数Kおよび蓄電量Sを算出する。蓄電量が上限値Supと下限値Slowの間の使用範囲に収まれば、このとき算出された電気価値係数Kを採用する。蓄電量が使用範囲を逸脱したら(t1)、蓄電量が最大Smaxまたは最小となる時点(t2)までの区間を第1の区間とし、電気価値係数Kの算出を行い、これをこの区間の電気価値係数K1として採用する。次に、第1の区間の終点(t2)を始点とし、目的地点を終点とした区間において、前回と同様の処理を実行する。これを終点が目的地点に達するまで繰り返し、各区間ごとに電気価値係数K1,K2,K3・・・を設定する。【選択図】図8
