Zusammenfassung:	To adjust distribution of a battery output and a power generation output so as to secure a driving force of a vehicle while avoiding an insufficient charge amount of a battery.SOLUTION: A power generation control device of a vehicle includes an engine, a power generation motor which is driven by output of the engine and generates power, a battery, a driving motor, and a control device. When a request driving output is larger than a limit value of output of the battery and a system maximum output is larger than a minimum output required by supply to a vehicle, the control device is configured to lower the output of the battery to a range such that a voltage of the battery is equal to or larger than a voltage capable of outputting a power generation output. The request driving output is a driving output required by the vehicle, and the limit value of the output of the battery is a value determined by a charged state of the battery. The system maximum output is the total value of a current value of the output of the battery and the current value of the power generation output.SELECTED DRAWING: Figure 2 【課題】バッテリの充電量不足を回避しつつ車両の駆動力を確保できるようにバッテリ出力と発電出力との配分を調整する。【解決手段】本発明は、車両の発電制御装置であって、エンジンと、エンジンの出力により駆動されて発電する発電モータと、バッテリと、駆動モータと、制御装置と、を備える。制御装置は、要求駆動出力が、バッテリの出力の制限値よりも大きく、かつ、システム最大出力が、車両に供給が必要な最低限の出力よりも大きい場合に、バッテリの電圧が、発電出力を出力できる電圧以上となる範囲内に、バッテリの出力を低下させるように構成されている。なお、ここで、要求駆動出力は、車両が要求する駆動出力であり、バッテリの出力の制限値は、バッテリの充電状態によって決定される値である。また、システム最大出力は、バッテリの出力の現在値と発電出力の現在値との合計値である。【選択図】図２
