【Abstract】 The internet of vehicles serves as a new generation of safety technology after the seat belt and airbag, which brings together intelligent vehicles, ITS and mobile internet technologies. It has great potential economic and social benefits for improving personal travel and driving experience. Supported by the China Automobile Industry Innovation and Development Joint Fund of the National Natural Science Foundation of China(U1564212), this project was conducted through five aspects, i.e., traffic state sensing of connected vehicles, vehicular communication and VANETs construction, green driving service optimization, safe driving decision optimization, simulation platform construction and demonstration experiments. It has made key technological breakthroughs in high-precision vehicle positioning based on hierarchical fusion of multi-vehicle motion state information, hierarchical distributed communication network and access in large-scale heterogeneous vehicle network, traffic state estimation under V2 V environment, spatial-temporal analysis of multi-vehicle hazard accounting for positioning errors. The project achievements have been widely applied in the construction of the Internet of vehicles integration and application demonstration zone and the development of Internet of vehicles application scenarios, providing strong support for the industrialization of intelligent Internet of vehicles technology.更多还原
