Recently, at the Telematics sub forum of the China Satellite Navigation and Location Services Annual Conference, Zou Xingzhong, General Manager of the TS Business Department of Beijing NavInfo Technology Co., Ltd., stated that since 2005, the number of connected car users in China has increased from 50000 to 500000, and it is expected that by 2015, this number will reach 10 million, accounting for nearly 10% of the total number of car users at that time. From the perspective of major global markets, the continuously increasing growth curve of market size also proves that the development of Telematics has become a trend for major automobile manufacturers, with the North American market experiencing the most rapid development. The Internet of Vehicles has achieved significant development among the three major telecommunications operators in China. As of April 2011, China Unicom's intelligent vehicle system has been applied to over 288000 vehicles in 118 cities across the country, providing services such as vehicle positioning, vehicle scheduling, and information dissemination. Li Shuang, Deputy General Manager of China Unicom Shanghai Branch, said. Tang Changyuan, the captain of the Ningbo Public Security Traffic Police Branch, told reporters that intelligent transportation urgently needs to establish an information system connected to vehicles. The Internet of Vehicles is the integration of existing electronic information technology, connecting each car as an information source to the network through wireless communication methods. The use of the Internet of Things can calculate real-time traffic speed in urban road networks, automatically monitor and alert congested sections and intersections, timely release information, guide drivers to evacuate, and effectively alleviate the problem of urban traffic congestion. With the further development of intelligent transportation, people's travel will become more convenient, and intelligent transportation will make cities more smooth. Li Caiyu, Executive Vice President of Beijing Changlian Wanfang Technology Co., Ltd., is optimistic that the Chinese automotive electronics market is expected to surpass the United States in 2012. By 2015, China's planned automobile production will reach 25 million units, and the market size of connected vehicles is expected to exceed 150 billion yuan. This statement has been recognized by Yang Fangchun, Chairman of the China Internet of Vehicles Industry Technology Innovation Strategic Alliance and Vice President of Beijing University of Posts and Telecommunications. He stated that the Internet of Things is China's Internet of Things industry; Twelfth Five Year Plan; The important integration promotion and demonstration application areas of planning. “ The rise of the Internet of Vehicles is in line with the development trend of China's modern service industry and will bring profound changes to China's future industrial and socio-economic development. ” It is understood that the national industry regulatory authorities attach great importance to the development of the leading field of vehicle networking. The IoT plan and relevant policies formulated by the Ministry of Industry and Information Technology in recent years have included smart transportation as a key demonstration area, with projects such as vehicle networking applications becoming important entry points. The Ministry of Industry and Information Technology will also support technology research and development for intelligent transportation and connected vehicles through various means such as special funds, to promote the development of related technology industries.
