The invention relates to the field of vehicles, in particular to a vehicle power supply system and a vehicle power distribution box. The vehicle power supply system comprises a power supply module, and the power supply module is used for supplying power to the first vehicle electric equipment, the main vehicle controller and the standby vehicle controller; the power supply module comprises a first power supply module which is used for being connected with a first vehicle power supply and supplying power to the main vehicle controller when a first power supply signal of the first vehicle power supply is effective; the second power supply module is used for accessing a second path of vehicle power supply and supplying power to the standby vehicle controller when a second power supply signal of the second path of vehicle power supply is effective; and the redundant power supply module is used for accessing a first vehicle power supply and a second vehicle power supply and supplying power to the first vehicle electric equipment when any one of the first power supply signal and the second power supply signal is effective. Therefore, power supply for the first vehicle electric equipment can be ensured, the requirement for vehicle power supply quality is reduced to a certain extent, and the reliability of a vehicle power supply system is improved.

    本公开涉及车辆领域,具体地,涉及一种车辆供电系统和车用配电箱。车辆供电系统包括供电模块,供电模块用于为第一车辆用电设备、主车辆控制器和备用车辆控制器供电;其中,供电模块包括:第一电源模块,用于接入第一路车辆电源,并在第一路车辆电源的第一电源信号有效时为主车辆控制器供电;第二电源模块,用于接入第二路车辆电源,并在第二路车辆电源的第二电源信号有效时为备用车辆控制器供电;冗余电源模块,用于接入第一路车辆电源和第二路车辆电源,并在第一电源信号和第二电源信号中的任一者有效时为第一车辆用电设备供电。如此,可确保为第一车辆用电设备供电,在一定程度上降低对车辆供电质量的要求,提高车辆供电系统的可靠性。
