PROBLEM TO BE SOLVED: To improve problems without depending on the improvement of a large-capacity secondary battery, one problem being a portion which a large-capacity secondary battery occupies in a vehicle weight and vehicle price, this problem being a greatest challenge to the popularization of electric automobiles and the other problem being an insufficient cruising distance due to a low energy density.SOLUTION: Energy saving effect of a vehicle is obtained by causing kinetic energy obtained by the vehicle due to an acceleration travel to be used for an energy saving deceleration travel mainly consisting of an inertia travel toward a targeted deceleration/stop position. The amount of the energy saving effect of the vehicle is used for a removal of a regenerative brake function and reduction of the capacity of a large-capacity secondary battery and thereby to achieve decrease in the price and weight of electric automobiles and further to use decrease in travel resistance obtained as the result of the decrease in the weight for increasing a cruising distance as a further energy saving effect.SELECTED DRAWING: Figure 1 【課題】電気自動車普及の最大の課題である大容量二次電池の車両重量および車両価格に占める大きさ、あるいはエネルギー密度の低さによる航続距離の不足、の問題を、大容量二次電池の改良に依らずに、改善する。【解決手段】加速走行の結果車両が獲得した運動エネルギーを、目標減速・停止点に向けての惰性走行を主体とする省エネルギー減速走行に活かすことによって得られる車両の省エネルギー効果分を、回生制動機能の除去および大容量二次電池容量の削減に活かし、電気自動車価格および重量の低減を図るとともに、前記重量の低減の結果として得られる走行抵抗の低減を更なる省エネルギー効果として航続距離拡張に活かす。【選択図】 図１
