To suppress a decrease of use opportunities of a functioning portion due to power supply, in a vehicle mounted with the functioning portion functioning for ensuring the safety of traffic such as automatic operation.SOLUTION: A vehicle power supply system is mounted on a vehicle capable of at least partially performing autonomous operation, and is equipped with a main power supply system, a back-up power supply system, and a high-pressure power supply. A back-up power supply control device can execute estimation processing estimating supply possible power which can be supplied from a back-up low-pressure power supply. During a vehicle performing autonomous operation in an autonomous operation mode, the back-up power supply control device, if the supply possible power is less than a second threshold value, outputs a signal indicating that a vehicle is prohibited to perform autonomous operation in the autonomous operation mode, and if the supply possible power is a third threshold value or less, outputs a signal indicating that the vehicle continues the autonomous operation mode and it is permitted to charge the back-up low-pressure power supply by power generated by the high-pressure power supply.SELECTED DRAWING: Figure 1

    【課題】自動運転など交通の安全性確保のために機能する機能部を搭載した車両において、電源供給に起因する機能部の利用機会の減少を抑制する。【解決手段】車両電源システムは、少なくとも部分的に自律運転可能な車両に搭載され、主電源系統と、バックアップ電源系統と、高圧電源と、を備え、バックアップ電源制御装置は、バックアップ低圧電源から供給可能な供給可能電力を推定する推定処理を実行可能であり、車両が自律運転モードで自律運転しているとき、供給可能電力が第2閾値未満である場合には、車両が自律運転モードで自律運転することを禁止することを示す信号を出力し、供給可能電力が第3閾値以下である場合には、車両が自律運転モードを継続し、かつ、高圧電源が発生する電力によりバックアップ低圧電源を充電することを許可することを示す信号を出力する。【選択図】図1
