To provide an on-vehicle power source device and an on-vehicle power source control method which enable a vehicle to perform safe evacuation travel even when an ignition line is disconnected while the vehicle is traveling.SOLUTION: An on-vehicle power source device comprises a first system, a second system, an inter-system switch and a control section. In the first system, electric power of a first power source is supplied to a first load for automatic operation. In the second system, electric power of a second power source is supplied to a second load for the automatic operation. The inter-system switch is capable of connecting and disconnecting the first system to and from the second system. When detecting a power supply failure in the first system, the control section disconnects the inter-system switch and causes the second system to enable the vehicle to perform evacuation travel. When detecting that an ignition is turned off and the vehicle is under automatic operation, the control section prohibits a process to be performed when the ignition is turned off.SELECTED DRAWING: Figure 1
【課題】車両の自動運転中にイグニッションラインが断線しても、車両を安全に退避走行させることができる車載電源装置および車載電源制御方法を提供する。【解決手段】実施形態に係る車載電源装置は、第1系統と、第2系統と、系統間スイッチと、制御部とを備える。第1系統は、第1電源の電力が自動運転用の第1負荷に供給される。第2系統は、第2電源の電力が自動運転用の第2負荷に供給される。系統間スイッチは、第1系統および第2系統を接続および切断可能である。制御部は、第1系統の電源失陥を検出した場合に、系統間スイッチを遮断し、第2系統によって車両に退避走行を行わせる。制御部は、イグニッションオフを検出した場合に、車両が自動運転中であれば、イグニッションオフ時に行う処理を禁止する。【選択図】図1
