The invention discloses a method for remotely flashing an ECU (Electronic Control Unit) on an engineering machinery vehicle networking platform. The method comprises a pre-upgrading part and an actual upgrading part. Pre-upgrading: the OTA platform requests a software upgrading package from the manufacturer platform, downloads and decompresses the software upgrading package, transcodes the software upgrading package and uploads the software upgrading package to the FTP server, the OTA platform sends a pre-upgrading instruction to the T-BOX, the T-BOX starts an ECU upgrading session and obtains a session type and a Seed value, then the session type and the Seed value are returned to the OTA platform, and meanwhile, the upgrading session is maintained to wait for actual upgrading. And actual upgrading: the OTA platform requests a secure access interface from the manufacturer platform according to the session type and the Seed value returned by the T-BOX and obtains a Key value, then constructs an upgrading inst
