Behind the series of dazzling keywords of â€œzero accidentsâ€, â€œno congestionâ€ and â€œauto-drivingâ€, the Internet of Vehicles that appeared in the â€œInternet of Things Preferred Applicationâ€ was still a mess.
At the end of October 2010, a message that â€œthe Internet of Vehicles will be written into the national science and technology major project and has huge financial supportâ€ made the concept of car networking a hit in the capital market. Stocks related to automotive electronics and intelligent transportation rose, and many stocks once rose to the limit, and the concept network of the Internet of Vehicles was born.
The concept of car networking under the hot speculation has quickly become popular, but the business value and technical model are like a fog. "It is too early to discuss the realization of the Internet of Vehicles," said Xing Tao, a researcher at the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences. The reporter of the "Financial Weekly" pointed out that "technology, market, standards, business models, etc. are lacking, and the entire industry still It takes a long time to build up."
Compared with the smart grid, security and other fields, the Internet of Vehicles is not the most mature and closest application to the Internet of Things applications, but with its strategic height and huge consumer market, it still won strong attention.
The emergence of the Internet of Vehicles has brought industrial upgrading opportunities to areas such as automobile manufacturing, content delivery and mobile communications. On the one hand, it has promoted the automotive industry from pure hardware sales to a new model of service and content bundling; on the other hand, it allows operators and service providers to quickly locate high-end customer groups and provide products and services. In addition, the state's requirement for new energy vehicles to â€œhave to have remote monitoring capabilitiesâ€ also allows the Internet of Vehicles to span two strategic emerging industries.
The so-called car network is not strictly defined. Simply put, the car is used as a node in the information network to realize the intelligent interaction of people, vehicles, roads and environment through wireless communication and other means. However, since the day of its birth, the Internet of Vehicles has always faced the â€œunmannedâ€ situation of lack of unified management.
â€œThe most critical issue in the current Internet of Vehicles is multi-head management.â€ Wang Lijian, secretary-general of the China Internet of Things Standards Joint Working Group, told the â€œFinancial Weeklyâ€ reporter that the automobile manufacturing and manufacturing department is under the Ministry of Public Security, and the operation is carried out by the Ministry of Communications. The three major management departments are all in one piece. It is not clear who will come out as the main body. There are not only one or two industry associations around the automobile. At the same time, several departments have their own projects related to the Internet of Vehicles, and it is not known whether they can be integrated into one system.
In this regard, Zhang Xiaoyu, president of the China Automotive Engineering Society, said that the automotive industry is only a target of service and will not do overall planning work. "We are also new to the concept of car networking, and it is not clear."
Compared with the three major management departments, mobile operators, automotive electronics companies, content providers, and service providers are more interested in participating in the Internet of Vehicles. Due to the long chain of the Internet of Vehicles industry and the participation of many industries, the understanding of the â€œBlind Touchâ€ style of the Internet of Vehicles is everywhere, and the interest game is also inevitable.
"Now it is basically chaotic. Many people are talking about the Internet of Vehicles from different angles." Li Haifeng, director of the Information Technology Research Office of the Ministry of Communications Science and Technology, explained to the reporters of the "Financial Weekly" that in intelligent transportation and ITS (Intelligent Transportation) In the framework of the system, the Internet of Vehicles should be the meaning of the coordination of vehicles and roads, and it is the product of the qualitative transformation of traffic informationization to a certain stage.
Technical short board
Sun Qibo, an associate professor at Beijing University of Posts and Telecommunications, told the "Financial Weekly" reporter that with the birth of the concept of car networking, automotive electronics has changed from mechanical and safety to emphasizing system integration capabilities, as well as vehicles and vehicles, vehicles and the environment. Collaborative interaction between.
The Internet of Vehicles addresses the problem of information exchange and sharing between systems, while enabling effective interaction with drivers and passengers. In addition, the car network is connected through the body network, and can also obtain various sensor data in the body, which can be used for alarm or remote diagnosis after processing. However, the vast majority of high-end sensors used for information acquisition, the core technology of the chip is not mastered by Chinese companies.
At the same time, the communication network bandwidth bottleneck has become a technical problem in the Internet of Vehicles. Li Haifeng believes that the current 3G network bandwidth can not meet the future transmission requirements for image and streaming media, and the independent network technology of 4G network and DSRC (dedicated short-range communication) has not yet completely broken through.
When the collected information is collected in the data center, it needs to be stored, interacted and analyzed. In China, cloud computing and ultra-large data processing have not yet mastered the core technology. Finally, on the basis of comprehensively obtaining accurate information of the system, the intelligent processing for different applications is a worldwide problem, and it requires a lot of work to study the mathematical model of intelligent application.
Wang Lijian believes that at present, China has a certain level in chip design and development, but the problem of independent controllable and manageable is still grim. "China's Internet domain name system and address, as well as the bar code of the goods, are all using foreign technology systems and coded addresses. The car network cannot be repeated in the vehicle logo." Wang Lijian said.
In fact, the Ministry of Public Security has introduced a special electronic tag with a recognition rate of over 99.9%, which can be installed on the windshield of a car to form a unique identification of vehicle identity and location information. However, to track vehicle information, a certain density of data collection facilities needs to be deployed in the surveillance area.
Mode is difficult
In the face of huge market temptations, related companies in the Internet of Vehicles are reluctant to wait for technology and management to break. Telecom operators, automotive electronics and service companies, and even auto trading companies have begun to move forward with a simplified version of the car-networking operating model â€“ integrating around in-vehicle intelligence platforms to enable integration of content and applications.
With the advantage of the mobile network channel, the current three major operators in the car network promotion method is basically to connect the car intelligent terminal with the wireless channel to provide real-time traffic conditions, navigation, rescue positioning, vehicle condition detection, 4S shop reservation and other operations. Services, mostly based on call centers or mobile Internet, do not involve any new technology, just a new business expansion based on the existing network.
"But this is still far from the Internet of Vehicles. Many services are provided by people. Is this the Internet of Things?" Xing Tao questioned that the real Internet of Vehicles should be the integration of multiple information systems, people and vehicles. The information between the road and the environment is interoperable, and the Internet of Vehicles based on the Internet of Things technology.
"Now the relevant standards have not been introduced, and even the initial stage can not be counted. However, under the current technical conditions, those who can see the benefits immediately, and only this model." Xing Tao said.
But even this existing model does not guarantee success in business models. The so-called "vehicle networking" products and services that are currently entering the market are all automakers paying for end users, usually one to three years, and whether they will renew their services after expiration is still unknown.
"Overseas renewal rate is only about 30%. In the final analysis, the business model is where the money comes from. The most important thing is how to let the end users take the initiative to pay the bill. This is not solved. It is wrong to rely on internal coordination within the industry." Shanghai Huihan Shen Jian, chairman of Information Technology Co., Ltd., told the reporter of Caijing National Weekly.
In fact, companies currently engaged in automotive information services are rarely profitable, and operating costs are relatively high. If the problem of charging models cannot be solved, it will become quite dangerous. To some extent, these pioneering car networking services have also become the touchstone for the development of the entire industry. If a matching business model cannot be found, the Internet of Vehicles industry will become difficult to survive even if management and technical issues are resolved in the future.
In addition, due to the lack of unified planning, many enterprises integrate the functions of the vehicle intelligent platform to meet the driver's use, and ignore the government's consideration of vehicle and traffic management. "Car space is more valuable, we are leading the organization of experts to confirm that to ensure that all the functions that the future car network can achieve on an intelligent platform, the market will not be chaotic in the future." Li Haifeng said.
