PROBLEM TO BE SOLVED: To assist the starting of an engine.SOLUTION: A state of a main battery 32 is diagnosed, and, if engine is determined to be not possible to start with power supplied from the main battery 32, the engine is started with power supplied from a sub-battery 33 that has higher durability against repeated charge-discharge than the main battery 32 when starting the engine in the next time. Incidentally, if the sub-battery 33 is in a predetermined charged state, the power is supplied from the sub-battery 33. Further, re-starting of the engine is tried with power supplied from the sub-battery 33, and if the engine is successfully started, the event is reported to a driver.SELECTED DRAWING: Figure 2

    【課題】エンジンの始動を補助する。【解決手段】メインバッテリ32の状態を診断する。診断の結果、メインバッテリ32から供給される電力ではエンジンを始動できないと判断したときには、次回、エンジンを始動する際に、メインバッテリ32よりも充放電の繰り返しに対する耐久性が高いサブバッテリ33から電力を供給してエンジンの始動を行なう。なお、サブバッテリ33が予め定めた充電状態であるときに、サブバッテリ33から電力を供給する。また、サブバッテリ33から電力を供給して再びエンジンの始動を試み、エンジンの始動に成功したときには、その旨を運転者に通知する。【選択図】図2
