The invention relates to a power distribution system of an autonomous vehicle. In the system, a key switch is connected with an enabling end of a BMS and a first awakening end of a power supply management module; the second awakening end of the power supply management module is connected with the output end of the network connection terminal; the DC/DC module and the output of the low-voltage storage battery are connected with the input end of the normalizing branch, and the output of the normalizing branch is connected with the network connection terminal, the power supply management module, the EPB, the IBC and the automatic driving control module. The normalizing branch is connected with the input end of the first power supply redundancy branch through a contact of the first redundancy relay, and the normalizing branch is connected with the input end of the first power supply branch through a contact of the first relay; a control coil of the first relay is connected with the power supply management module; a control coil of the first redundant relay is connected with the automatic driver; the output of the power supply management module is connected with a BMS starting wake-up relay; the outputs of the first power supply branch and the first power supply redundant branch are connected with a plurality of core devices. The system reliably realizes local and remote start/stop of the vehicle through various redundancy settings.
