The invention relates to the technical field of automatic driving, and particularly discloses a vehicle power supply system and a redundant power distribution method. The vehicle power supply system comprises a main power supply, a standby power supply and an isolation switching module, the first end of the isolation switching module is connected with the load, the second end of the isolation switching module is connected with the main power supply, and the third end of the isolation switching module is connected with the standby power supply; the isolation switching module is used for collecting a first voltage signal output by the main power supply; and the isolation switching module is also used for switching the main power supply connected with the load to the standby power supply when the first voltage signal is lower than the first threshold signal. By arranging the redundant standby power supply, when the power supply of the main power supply to the post-stage load is in single-point failure, the standby power supply can be used for supplying power to automatic driving and safe operation related components, and safe operation of the automatic driving is ensured.

    本发明涉及自动驾驶技术领域,具体公开了一种车辆供电系统及冗余电源分配方法。该车辆供电系统包括:主电源、备用电源和隔离切换模块;隔离切换模块的第一端与负载连接,隔离切换模块的第二端与主电源连接,隔离切换模块的第三端与备用电源连接;隔离切换模块,用于采集主电源输出的第一电压信号;隔离切换模块,还用于在第一电压信号低于第一阈值信号时,将负载连接的主电源切换为备用电源。通过设置有冗余的备用电源,在发生主电源向后级负载的供电发生单点失效时,可以使用备用电源为自动驾驶以及安全操作相关的部件进行供电,确保自动驾驶的安全运行。
