Research on Methods for Developing Software Identification Codes in Automotive Software Update Management Regulations

As vehicles become increasingly digitized and intelligent, with growing demands for functional iterations, software updates (OTA) are becoming more frequent. National regulatory agencies have taken corresponding measures to address the risks associated with automotive software updates. To enhance the automotive industry's standards and maintaina healthy industry ecosystem, it is urgent to establish requirements for managing software identification codes and tracking software changes. Current software update management documents, primarily the UN R156 regulation and the forthcoming GB "General Technical Requirements for Automotive Software Updates," specify requirements for software identification codes. Based on the UN R156 regulation and research on existing automotive code systems in China, we propose ideas and methods for developing software identification codes.
