Study on compatibility of vehicular communication application standard system
With the rapid development of intelligent connected vehicle (ICV) technology
the cooperative intelligent transportation application standard system has been facing compatibility challenges due to the coexistence of multiple protocol versions. The study focused on the vehicular communication application system
systematically verified and analyzed the inheritance and extension relationships between application scenarios and message sets across different versions
and proposed a compatibility evaluation model based on ASN.1 syntax rules. The study reveals that the Phase 1 message sets exhibit backward compatibility at the syntactic level. However
during the functional iteration of Phase 2 standards
compatibility limitations emerged in some message bodies due to scenario refinement requirements. Based on these findings
the study proposed suggestions for source code management mechanisms and industry deployment strategies
to provide a theoretical foundation for industrial- scale applications.
