Abstract

The invention provides an upgrading system and method for ECU software in an engineering machinery vehicle. A mobile terminal is in communication connection with an Internet of Things server. The ECUterminal is connected with the mobile terminal through the protocol conversion module and the upgrading wire harness. An upgrade package file of ECU software is stored in the Internet of Things server. The mobile terminal firstly downloads the upgrade package file from the Internet of Things server, then is connected to the ECU terminal through the upgrade connecting line and the protocol conversion module and transmits the upgrade package file to the ECU terminal, and finally the ECU terminal receives the upgrade package file and upgrades ECU software according to the upgrade package file. The ECU software in the engineering machinery vehicle can be upgraded through simple operation, ECU software upgrading equipment does not need to be carried, convenience is brought to operators, the upgrading efficiency is improved, and meanwhile the labor cost and the upgrading cost can be greatly saved.
