Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vehicle that prevents charging power to a power storage device from becoming excessive due to surplus generated power while, when a required driving force of a vehicle driven by a rotary electric machine decreases, surplus generated electric power is generated due to a response delay of an electric power generating device or the like.SOLUTION: Excessive generated electric power on the basis of a response delay of an FC unit 12 is generated by detecting that a required driving force to a motor generator 20 of a vehicle 10 has decreased and decreasing an electric power generation amount of the FC unit 12. When charge restriction is imposed on a high voltage battery (power storage device) 14, the motor generator 20 is driven with a phase current Ia' which is different from a phase current Iamin at which a current value or loss at a time of generating a predetermined driving force is the smallest to consume the excessive generated power.SELECTED DRAWING: Figure 1
【課題】回転電機により駆動される車両の要求駆動力が減少した場合に、発電装置等の応答遅れを原因として余剰な発電電力が発生する。この余剰な発電電力によって蓄電装置への充電電力が過剰になることを防止する車両を提供する。【解決手段】車両10のモータジェネレータ20に対する要求駆動力が減少したことを検出して、FCユニット12の発電量を減少させると、FCユニット12の応答遅れに基づく余剰な発電電力が発生する。高圧バッテリ(蓄電装置)14に充電制約があるとき、モータジェネレータ20を、所定の駆動力を発生させる際の電流値又は損失が最も小さくなる相電流Iaminとは異なる相電流Ia´によって駆動して余剰な発電電力を消費させる。【選択図】図1 |
