The invention provides a vehicle power supply system. The purpose of the present invention is to suppress a reduction in the opportunity of use of a functional unit due to power supply in a vehicle equipped with the functional unit that functions in order to secure traffic safety, such as automatic driving. The vehicle power supply system is mounted in a vehicle capable of at least partially autonomous driving, and is provided with a main power supply system, a backup power supply system, and a high-voltage power supply, and a backup power supply control device is capable of executing an estimation process for estimating the power that can be supplied from the backup low-voltage power supply. And a controller configured to output a signal indicating that autonomous driving of the vehicle is prohibited in the autonomous driving mode when the power that can be supplied is lower than a second threshold value, and output a signal indicating that the vehicle is allowed to continue the autonomous driving mode and that the standby low-voltage power source is charged by the power generated by the high-voltage power source when the power that can be supplied is lower than a third threshold value.
本发明提供车辆电源系统。在搭载了自动驾驶等为了确保交通的安全性而发挥功能的功能部的车辆中,抑制因电源供给而导致的功能部的利用机会的减少。车辆电源系统搭载于至少能够部分地进行自主驾驶的车辆,具备主电源系统、备用电源系统、高压电源,备用电源控制装置能够执行估计能够从备用低压电源供给的可供给电力的估计处理,在车辆以自主驾驶模式进行自主驾驶时,在可供给电力低于第2阈值的情况下,输出表示禁止车辆以自主驾驶模式进行自主驾驶的信号,在可供给电力为第3阈值以下的情况下,输出表示允许车辆继续自主驾驶模式且通过高压电源产生的电力对备用低压电源进行充电的信号。
