PROBLEM TO BE SOLVED: To provide a control method and a control apparatus for an automatic driving vehicle power supply, the method and apparatus that prevent the capacity of an additional battery from increasing while securing the continuation of automatic driving functionality.SOLUTION: A first load circuit 1, using a lead battery 11 as power supply, interconnects a starter motor 12 necessary for continuing a normal drive mode by a driver and a load actuator 13. A second load circuit 2, using a lithium ion battery 21 as power supply, interconnects automatic drive function loads 22, 23, 24 that are required to continue an automatic drive mode and require a voltage to be maintained. A circuit disconnect-connect mechanism 3 connects or disconnects between the first and second load circuits 1, 2. In controlling this automatic driving vehicle power supply, the circuit disconnect-connect mechanism 3 is shut off in a case where power output from the lithium ion battery 21 toward the first load circuit 1-side is determined on the basis of a load condition detected on the second load circuit 2-side while the circuit disconnect-connect mechanism 3 is connected.SELECTED DRAWING: Figure 2

    【課題】自動運転機能の継続を確保しつつ、追加バッテリが大容量化されることを防止する自動運転車両電源の制御方法と制御装置を提供すること。【解決手段】第1負荷回路1は、鉛バッテリ11を電源とし、運転者による通常運転モードの継続に必要なスタータモータ12、負荷アクチュエータ13を接続する。第2負荷回路2は、リチウムイオンバッテリ21を電源とし、自動運転モードの継続に必要であり、かつ、電圧の維持が必要である自動運転機能負荷22,23,24を接続する。回路断続機構3は、第1負荷回路1と第2負荷回路2を接続又は遮断する。この自動運転車両電源の制御において、回路断続機構3の接続中、第2負荷回路2側で検出される負荷状態に基づき、リチウムイオンバッテリ21から第1負荷回路1側への電力持ち出しになることが判断されると、回路断続機構3を遮断する。【選択図】図2
