To provide a vehicle power supply device, vehicle power supply control method, and vehicle power supply control program that can safely return a state to a power supply state before erroneous detection after a power supply failure is erroneously detected.SOLUTION: A vehicle power supply device comprises: a first system that supplies power from a first power supply to a first load; a second system that supplies power from a second power supply to a second load; a first switch that connects the first system and the second system; a second switch that connects the second power supply to the second load; and a control unit that realizes a fail-safe state where the first switch is turned OFF and the second switch is turned ON when detecting that a power supply failure has occurred in one of the first system and the second system during a normal state where the first switch is ON and the second switch is OFF. The control unit returns the state to the normal state by turning the second switch OFF after turning the first switch ON when the occurrence of the power supply failure is not detected in a case where the first switch and the second switch are in the fail-safe state.SELECTED DRAWING: Figure 1

    【課題】電源失陥が誤検出された後、安全に誤検出前の電源状態に復帰させることができる車両電源装置、車両電源制御方法、および車両電源プログラムを提供する。【解決手段】車両電源装置は、第1電源から第1負荷へ電力を供給する第1系統と、第2電源から第2負荷へ電力を供給する第2系統と、第1系統と第2系統とを接続する第1スイッチと、第2電源と第2負荷とを接続する第2スイッチと、第1スイッチをオン、第2スイッチをオフにしている正常状態のときに、第1系統および第2系統のうち一方の系統に電源失陥が発生したことを検出すると、第1スイッチをオフ、第2スイッチをオンにするフェイルセーフ状態とする制御部と、を備える。制御部は、第1スイッチと第2スイッチとがフェイルセーフ状態のときに、電源失陥の発生が検出されなかった場合、第1スイッチをオンした後に第2スイッチをオフにすることで正常状態に復帰させる。【選択図】図1
