Vehicle ECU data list difference comparison method, system and device and storage medium

The embodiment of the invention relates to the technical field of automobiles, in particular to a vehicle ECU data list difference comparison method, system and device and a storage medium. The method mainly comprises the steps of obtaining a to-be-compared data list and a historical data list, splicing the to-be-compared data list and the historical data list to generate a merged data list, identifying multiple groups of repeated part information in the merged data list, performing deletion processing, and generating a difference data list, according to the unique identifier in the difference data list, target difference data in the to-be-compared data list is determined, visual labeling is conducted on the target difference data to obtain a comparison result list, and the comparison result list is output and used for being uploaded to a vehicle information management platform to update ECU version data of the vehicle. By adopting the method, the efficiency and the accuracy of difference comparison of the EC
