According to Tianyancha intellectual property information, on December 3, the patent "Method, system, and vehicle for smooth switching of faults in autonomous driving vehicle systems" applied by BYD Company Limited was published. The abstract states that the method includes: for multiple logically related subprocesses included in the generation of decision information, the first processing unit and the second processing unit respectively obtain their own subprocess processing result data; the first processing unit and the second processing unit respectively save their own subprocess processing result data as local data blocks and send the processing result data to each other; the first processing unit and the second processing unit respectively save the received counterpart's subprocess processing result data as synchronization data blocks; when preset primary and backup switching conditions are met, the first processing unit and the second processing unit perform primary and backup switching, with the unit originally designated as the backup generating decision information based on the synchronization data blocks. This method can continuously generate current decision information during the primary and backup switching, achieving smooth switching of the autonomous driving vehicle system.
