The invention provides a vehicle power supply system. The purpose of the present invention is to reduce the size and cost of a power supply system for supplying power to a functional unit in a vehicle equipped with the functional unit that functions in order to ensure traffic safety. A vehicle power supply system includes: a main power supply system having a main low-voltage power supply and a normal load; the standby power supply system is provided with a standby low-voltage power supply and an emergency important load; and a vehicle control device. When an operation for starting the load is performed, the vehicle control device executes a normal determination process for a period until the load is started, and when it is determined that the backup power supply system is normal in the normal determination process, the vehicle control device executes a normal determination process for a period until the load is started. The operation of controlling the main switch to perform connection and the operation of controlling the sub switch to perform disconnection are completed.
本发明提供车辆电源系统。在搭载了为了确保交通的安全性而发挥功能的功能部的车辆中,能够实现对功能部进行电力供给的电源系统的小型化和低成本化。车辆电源系统具有:主电源系统,其具有主低压电源和通常负载;备用电源系统,其具有备用低压电源和紧急时重要负载;以及车辆控制装置。在进行了使负载起动的操作的情况下,在到负载起动为止的期间内,车辆控制装置执行正常判定处理,在正常判定处理中判定为备用电源系统正常的情况下,车辆控制装置在到负载起动为止的期间内,使控制主开关而进行连接的动作以及控制副开关而进行切断的动作完成。
