The lack of four key technologies in domestic vehicle management systems

With the development of the internet of vehicles market, the vehicle operation management system represented by Suzhou Jinlong Hager G-BOS and Yutong Anjietong has been rapidly promoted throughout the country. Compared with the fleet management systems developed by Mercedes, Scania, Mann, and other famous automobile companies, G-BOS, Anjietong and other systems are basically the same in function. From this point of view, the vehicle management system developed by China's passenger vehicle companies has been in line with international standards. However, due to the rapid development, many related work has not kept pace with, and many problems have been faced in the new vehicle management system. The four most important issues are the four major issues.

Lack of core technology

The lack of core technologies is a common problem encountered in the development of China's automotive industry, and it is also true in vehicle management technology. The main partner of Hager G-BOS software is a domestic software company. Yutong Antong's software partners are internationally renowned Nokia Siemens Networks. Lei Hongjun, dean of the Dongfeng Yangtze River City Bus Engineering Research Institute, told reporters: “These systems developed by Chinese bus companies are based on existing technologies in the communications industry and integrated development with the characteristics of the industry.” In other words, the core technologies Not in the hands of bus companies.

Dr. Zhang Wei from the Traffic Information Center of the Institute of Science and Technology of the Ministry of Transport told the reporter that at present, the development of the Internet of Things in China is still in its infancy, and core technologies are generally lacking. The Internet of Things technology has taken the lead in foreign countries. Our country has always followed the strategy development. Technology R&D and industrial development have obviously lagged behind foreign countries. The industry chain of China's Internet of Things is very long, but it lacks core technologies and lacks leading enterprises, and its R&D and production base is weak. In contrast, the technical level of the related systems developed by the passenger car industry lags even further.

Because there are many companies engaged in the research and development of car networking technology in the society, when Suzhou Golden Dragon G-BOS opens the market, other companies can quickly follow up. At the 2011 Beijing Bus Show, almost all exhibitors launched similar products, many visitors exclaimed "I did not expect." At the same time, exhibiting products have shown varying degrees of homogeneity. Under such circumstances, mastering core technologies and developing vehicle networking technologies with its own characteristics have become a priority and survival path for bus companies.

No industry standard

Jinan Public Transport Corporation is an early large-scale application of 3G technology for public transportation companies. Shi Shaoteng, deputy general manager of the company, understands the vehicle management systems of domestic passenger car companies. He told reporters that domestic passenger car companies do not have unified platforms and interface standards as reference when developing related systems. The consequence of the lack of standards is that all companies are going their own ways in R&D, and the products they develop are varied, laying down hidden dangers for after-sales service.

Wang Jian, a professor at Chongqing Jiaotong University’s Express Bus Research Center, told reporters that the establishment of standards can allow bus companies to use the same interface for R&D systems, reduce passenger transportation company installation costs, increase system flexibility, and adapt to future interconnections.

The application of European fleet management systems was earlier and related standards were formulated. For example, the European Bus Management System Standard (2007) is based on the “European Fleet Management System Standard (2002)” for the European bus manufacturing industry in vehicles. An open interface standard for the exchange of information between electronic information systems (fleet management systems).

The Intelligent Bus Working Group (IBCS) affiliated to China's Taiwan Telematics Industry Association, in collaboration with Advantech, Baolu Electronics, Xinrui Information, CAYIN Technology, Ritek, and Chunghwa Telecom, have jointly established a relatively complete set of vehicle-mounted machines. The industry standard is named "Business Bus Passenger Vehicle Industry Standard".

China has a vast territory, a large population, long road mileage, and many people traveling by car. At the same time, there are many bus manufacturers and many passenger transport companies. A unified industry standard is even more important. The direct consequence of the lack of industry standards is that there are problems with the compatibility of vehicle management systems developed by different companies. The more developed the vehicle networking, the more serious the problem is.

System compatibility is hidden

Zhang Dong of the government-enterprise customer division of China Telecom Group stated: “Road passenger transport companies should promote the integration of car networking, inter-vehicle protocols for in-vehicle informatization, provincial and ministerial platforms, and on-board data, such as the standardization of CANBUS information format. Even with the same information transmission service providers, there are differences in the technologies used by China Telecom and China Unicom, which is exactly what many people worry about. The partner of Suzhou Jinlong Haige G-BOS system is China Unicom, and Yutong Anjietong's partner is China Mobile. Zhang Dong also talked about another issue. Before the bus companies introduced these systems, the Ministry of Communications established a GPS monitoring platform in the national passenger transport system to dynamically supervise vehicles. Now, because the vehicle networking system developed by bus companies has both GPS functions, it is inevitable that there will be conflicts with the original systems of the Ministry of Communications. How to handle such conflicts is a major obstacle for bus companies. It is understood that in the process of promoting Hagrid G-BOS, many road transport companies have expressed concern about this issue.

Corporate information security is difficult to maintain

Although the exploration of the car networking technology by bus companies has just begun, some people in the industry have expressed concern about possible corporate information security issues.

Li Chen, director of the Zhongtong Bus Technology Center, told reporters that since the Vehicular Network System can collect a large amount of data, the entire vehicle's running status and the fleet's operation lines are displayed to the people. Among them, the core data including parts and components companies and passenger transport companies are inevitably involved, leading to leakage of business secrets. How to deal with this relationship requires early consideration and the development of specific measures.

Dr. Zhang believes that the Internet of Things places traffic and related social and economic activities, strategic infrastructure resources and people’s lives on a globally connected network. All activities are transparent. Once under attack, corporate security and privacy will be Faced with huge threats.
