Abstract

The invention discloses an electric vehicle ECU software version detection method and system. The method is applied to an offline detector, and the offline detector comprises a code scanning gun, an industrial personal computer and an OBD plug. The method comprises the steps that the code scanning gun identifies a VIN number of a vehicle and sends the identified VIN number to the industrial personal computer; the industrial personal computer obtains an ECU software version number configuration table corresponding to the VIN number from a pre-stored database according to the VIN number; when the industrial personal computer receives a diagnosis instruction, the ECU software version number of the vehicle is read through the OBD plug; the industrial personal computer judges whether the read ECU software version number of the vehicle is consistent with the ECU software version number configuration table obtained from a database or not; and if the read ECU software version number of the vehicle is consistent with the ECU software version number configuration table obtained from the database, the industrial personal computer judges that the ECU software version detection of the vehicle is qualified. According to the invention, the problems of high detection cost and influence on vehicle stability and safety in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for detecting ECU software versions of electric vehicles. Background technique [0002] With the rapid development of the automobile industry, automobiles have become one of the indispensable means of transportation for people to travel. New energy vehicles, especially electric vehicles, are the current development direction of the automotive industry. [0003] At present, the automation and intelligence of electric vehicles are getting higher and higher, and the number of ECUs (Electronic Control Units) on electric vehicles is also increasing day by day. Each ECU carries and completes more and more functions, and the complexity is getting deeper and deeper. Software version control has become an inevitable inspection item for car companies. [0004] In the prior art, when testing the ECU software version of an electric vehicle, new hardware equipment ne...
