ECU upgrading method and system, electronic equipment and storage medium

The embodiment of the invention relates to the technical field of field bus communication, and discloses an ECU upgrading method and a system, electronic equipment and a storage medium. The method comprises the following steps: an automobile gateway sequentially receives upgrade packages of at least two ECUs transmitted by terminal equipment, and parallelly upgrades the at least two ECUs accordingto the upgrade packages of the at least two ECUs; wherein the upgrade package comprises an installation package and an upgrade instruction, after the upgrade package of the previous ECU in the at least two ECUs is received, the upgrade package of the next ECU is received, and the automobile gateway performs information interaction with each ECU in the at least two ECUs through the at least two CAN buses. The automobile gateway performs parallel upgrading on the at least two ECUs through the at least two CAN buses, so that compared with a serial upgrading method, the ECU upgrading time is saved, the problem that an au
