Automotive ECU remote update technology is an emerging field of intelligent technology of modern cars, but also the in- evitable trend of the future intelligent road vehicle. The remote update technology of automobile ECU based on the compatibility relation model is gradually adopted by the main engine factory. By studying the compatibility of the controller software, the version management service and the compatible relational computing service are established, and the binary code and version compatibility of the vehicle con- troller software are managed. Calculating and outputing of vehicle update strategy and update file are carried out. Through the integration of server, data layer, communication layer and brush client, we can realize the integrated application of automobile ECU remote update technology based on the compatibility relation model to enhance the efficiency of the factory and the 4S shop after-sales service.
