To provide a technique which is used in a vehicle power supply system having a plurality of power supply lines and suppresses the occurrence of undesirable condition in operation state of a controlled part due to communication delay when acquiring a voltage of a power line connected to the controlled part.SOLUTION: A vehicle power supply system 1A comprises an electric load 37 and a control device 10A. The electric load 37 is connected to a first power supply line 2. The control device 10A is connected to a second power supply line 4 which is different from the power supply line connected to the electric load 37 and is configured in such a manner that it acquires a parameter representing a predictive sign of a voltage change in the first power supply line 2 and sets an operation state of the electric load 37 according to the predictive sign represented by the parameter.SELECTED DRAWING: Figure 1
【課題】複数の電源系統を有する車両電源システムにおいて、被制御部が接続された電源系統の電圧を取得する際の通信の遅延に起因して、被制御部の作動状態に不都合が生じることを抑制する技術を提供する。【解決手段】車両電源システム1Aは、電気負荷37と、制御装置10Aと、を備える。電気負荷37は、第1電源系統2に接続される。制御装置10Aは、電気負荷37とは異なる電源系統である第2電源系統4に接続され、第1電源系統2の電圧変化の予兆を示すパラメータを取得し、パラメータが示す予兆に応じて電気負荷37の作動状態を設定するように構成される。【選択図】図1
