PROBLEM TO BE SOLVED: To provide a battery control system of a hybrid vehicle, which can secure performance of evacuation traveling when requested discharged electricity is increased at a request of a user during evacuation traveling.SOLUTION: A battery control system includes a control device for controlling a battery for electricity discharged. The control device, when an abnormality occurs in an engine or a charging system, prohibits driving of the engine and charging of the battery, and permits the vehicle to travel only in evacuation traveling in which the vehicle travels by setting discharge allowable electricity of the battery to a set value for evacuation traveling and driving an electric motor (S10); and during the evacuation traveling, when it is determined that requested discharged electricity of the battery is increased from operation amounts of an acceleration instruction portion and vehicle speed (S16), makes the set value for evacuation traveling to be higher comparing with when it is not determined that the requested discharged electricity is increased during the evacuation traveling (S17).SELECTED DRAWING: Figure 3
【課題】ハイブリッド車両のバッテリ制御システムにおいて、退避走行時におけるユーザからの要求で要求放電電力が増加したときに、退避走行の性能を確保することである。【解決手段】バッテリ制御システムは、バッテリに対する放電電力を制御する制御装置を含む。制御装置は、エンジンまたは充電システムに異常が発生したときに、エンジンの駆動とバッテリの充電とを禁止し、バッテリの放電許容電力を退避走行用設定値に設定して電動モータを駆動して走行する退避走行のみで走行を許可S10し、退避走行時では、加速指示部の操作量及び車速からバッテリに対する要求放電電力が増加したと判定S16されたときに、退避走行用設定値を、退避走行時に要求放電電力が増加したと判定されないときに比べて高くするS17。【選択図】図3
