PROBLEM TO BE SOLVED: To make effective use of energy when a vehicle travels on a descending slope at a relatively small gradient.SOLUTION: A hybrid electric vehicle 1 of the present invention comprises a control unit 10 that drives a motor-generator 12 as a generator so that an engine 11 can be driven with predetermined efficiency when the hybrid electric vehicle travels on a descending slope at a gradient equal to or smaller than a predetermined gradient, and that charges a battery 14 with electric power obtained as a result of driving the motor-generator.SELECTED DRAWING: Figure 1

    【課題】比較的小さい勾配の下り勾配路の走行におけるエネルギを有効に利用すること。【解決手段】本発明のハイブリッド自動車1は、所定の勾配以下の下り勾配路を走行する場合、エンジン11が所定の効率で駆動できるように、電動発電機12を発電機として駆動させ、その結果得られた電力をバッテリ14に充電させる制御装置10を有する構成とする。【選択図】図1
