The invention relates to the technical field of automatic driving, and provides an upgrading system for an automatic driving system, MCU firmware is split according to a configuration file to obtain first sub-firmware and second sub-firmware, the first sub-firmware and the second sub-firmware are sent to a firmware multi-channel receiving combiner through a first SPI transceiver module and a first Ethernet transceiver module respectively, synchronous transmission is carried out through different channels, and then the first sub-firmware and the second sub-firmware are upgraded. The transmission speed of the MCU firmware is increased through multi-channel transmission, and the upgrading time of the MCU firmware is effectively shortened; before MCU firmware transmission is carried out each time, system operation states of a CPU occupancy rate and network throughput between an SoC end and an MCU end are obtained in real time, loads of current wired transmission and network transmission are determined, then a configuration file mcufw.cfg file is generated and defined according to the most appropriate transmission proportion so as to be used for firmware transmission channel distribution, and by evaluating the operation state of the system in real time, the firmware transmission efficiency is improved. The data transmission efficiency is optimized to the maximum extent, and the upgrading rate is further improved.
