AI Technical Summary
In existing technologies, the ECU upgrade process for traditional gasoline vehicles is often interrupted by the lack of controller functionality, resulting in users being unable to use the vehicle during the upgrade process. This leads to excessively long upgrade times, increased user waiting time, and reduced user satisfaction.
By dividing the ECU into regions, setting logical partitions and utility identifiers, and preparing for the upgrade in advance in the non-operational area, the embedded controller upgraded using UDS FBL can be upgraded without the user's awareness. Multi-level bootloaders are used for security authentication and flashing to ensure that the upgrade process does not affect the normal function of the controller.
It shortens the vehicle upgrade time, reduces user waiting time, improves user experience, and enables ECU upgrades to be completed without the user's awareness.
