AI Technical Summary

Technical Problem

With the development of intelligent vehicles, more and more electronic controller units are required for OTA upgrades, resulting in limited CAN ID resources and cannot meet the upgrade needs of a large number of electronic controller units.

Method used

By connecting each electronic controller unit with the upgrade control unit, the upgrade control unit serves as the intermediate carrier between the diagnostic instrument and each electronic controller unit. There is no need to assign CAN ID to each electronic controller unit, and it is directly used to use the CAN ID of the upgrade control unit. Upgrade data transmission.

Benefits of technology

The security upgrade of multiple electronic controller units has been realized, reducing the configuration requirements of CAN ID, meeting the upgrade requirements of a large number of electronic controller units, and ensuring the security of upgraded data transmission.
