The development of Intelligent and Connected Vehicle（ICV）is an important way to improve traffic safety，relieve congestion，and reduce energy consumption and pollution emissions，and is an important domain to accelerate the building China’s strength in transport. In 2021，China has initiated the implementation pilot of ICV under specific scenarios，but the application of advanced functional technologies is still facing challenges，especially in driving environmental detection. Relevant regulations and policies show more efficient and pragmatic characteristics，but those for ICV utilized in real traffic system has not yet been considered. In terms of cyber and data security，ICV is also facing serious risks and challenges. ICV will continue to promote transport service mode upgrade and transportation system transformation.
