PROBLEM TO BE SOLVED: To control a hybrid electric vehicle so as to appropriately improve fuel economy.SOLUTION: A vehicle control unit (100) comprises: determination means (103) of determining whether a charging cost that represents the fuel consumption (F) of an internal combustion engine (ENG) required to accumulate unit electric energy in a rechargeable battery (500) is lower than an engine cost that represents the fuel consumption (H) of the internal engine required to output unit travel power without using the power of a rotating electric machine (MG1); control means (101) of controlling a hybrid electric vehicle so that the travel mode of the hybrid electric vehicle is set to an electric mode when the charging cost is lower than the engine cost and so that the travel mode is set to an engine mode when the charging cost is higher than the engine cost; and correction means (104) of correcting the charging cost so that the charging cost is close to the engine cost when the state in which the charging cost and the engine cost differ by a specified value (P1, P2) or more continues for time exceeding specified time (Q).SELECTED DRAWING: Figure 2
【課題】好適に燃費を向上させるようにハイブリッド車両を制御する。【解決手段】車両制御装置(100)は、充電池(500)に単位電力量を蓄積するのに要した内燃機関(ENG)の燃料消費量(F)を表す充電コストが、回転電機(MG1)の動力を用いずに単位走行出力を出力するのに要する内燃機関の燃料消費量(H)を表す機関コストよりも小さいか否かを判定する判定手段(103)と、充電コストが機関コストよりも小さい場合に、ハイブリッド車両の走行モードが電動モードとなり、充電コストが機関コストよりも大きい場合に、機関モードとなるようにハイブリッド車両を制御する制御手段(101)と、充電コスト及び機関コストが互いに所定値(P1、P2)以上乖離している状態が所定時間(Q)を超える場合に、充電コストを機関コストに近づけるように補正する補正手段(104)とを備える。【選択図】図2
