To suppress an excess increase in internal pressure of a battery.SOLUTION: A motor is controlled within ranges of permissible input power and permissible output power of a battery. In the case of predicting that internal pressure of the battery becomes higher than given internal pressure due to charging the battery by regenerating drive of the motor in a target downhill section of a travel plan route, permissible input power is decreased in the target downhill section. This makes it possible to suppress the input power of the battery from being excessive due to the regenerating drive of the motor in the target downhill section, thus suppressing the internal pressure of the battery from excessively climbing.SELECTED DRAWING: Figure 2 【課題】蓄電装置の内圧の過度の上昇を抑制する。【解決手段】蓄電装置の許容入力電力および許容出力電力の範囲内でモータを制御する。そして、走行予定ルートにおける対象下り坂区間でモータの回生駆動による蓄電装置の充電により蓄電装置の内圧が所定内圧よりも高くなると予測したときには、対象下り坂区間での許容入力電力を小さくする。これにより、対象下り坂区間で、モータの回生駆動による蓄電装置の入力電力が大きくなるのを抑制することができ、蓄電装置の内圧の過度の上昇を抑制することができる。【選択図】図２
