The bibliometric method is used to analyze the intelligent connected vehicle literature from 2000 to 2021, and the hot changes and development trends of domestic and foreign intelligent connected vehicle research are scientifically and objectively inferred and compared. The results show that both domestic and foreign scholars focus on the technical and safety aspects of research.Domestic scholars focus more on the technical aspects of China’s intelligent transportation construction and extend to the changes in the automotive industry and the legal responsibilities of artificial intelligence.While, foreign scholars focus more on the application of artificial intelligence technology and new algorithms to the Internet of Vehicles and autonomous driving, and extend outreach to a wider range of Internet of Things technologies and other aspects to explore cross-analysis of different disciplines.
