In addition, in an embodiment of the present invention, the interface information of the standard vehicle data determined based on the vehicle identification information includes a CAN bus interface inside the vehicle, data transmission interface information inside the vehicle, and ECU interface information of each component of the vehicle.
Finally, the system is used for judging whether the data are missing or not, judging which CAN bus or which ECU the missing data belong to, and if no data are missing, the system does not give an alarm; or judging the missing interface data in the vehicle data according to the interface information in the vehicle data and the determined standard vehicle data interface information, thereby generating alarm information.
If the data is missing, the system sends an alarm for warranty and prompts the possible position of fault transmission.
