The new hotspot of navigation industry market and technology

with the development of mobile communication, electronic integration and other technologies, it provides a broad application field for domestic viss and foreign telematics. Viss is a hierarchical and real-time information system based on vehicle location and characteristic information, which meets the requirements of vehicle operation environment, realizes vehicle operation state management, multimedia interaction of drivers and passengers, and the level of related information communication medium should be about 30mm lower than the workbench through mobile communication network

according to the four major components of the automobile, automotive electronics can include: power transmission, chassis control, body control, audio-visual communication and other electronic systems. Automotive electronic informatization has upgraded the single control unit based on electronic and electrical technology to a computer network system based on overall control, digital technology and information technology, and the control of each part is closely related and coordinated

viss benefits from the progress of various technologies, but its development comes from services. People, vehicles and roads realize the interaction of information and control through the services of on-board terminals and information centers, and realize the applications of intelligent transportation, vehicle management, information entertainment, safety and environmental protection, etc

viss system is composed of satellite positioning system, communication network, vehicle terminal and information center. The hierarchical structure of the system reflects the goals of communication network, unified information exchange protocol, arbitrary access of information center and construction of information service platform. The system protocol structure reflects the protocol entities of each layer and meets the requirements of openness and layering of the system

single function and simple service can no longer meet the requirements of the development of vehicle information service, and comprehensive information is the service goal of viss. Function is the smallest entity of the system. Under the control of the information center, different services are realized through function combination. In the mid-1990s, China began the application of vehicle information released by vehicle route tracking and scheduling instructions in special industries, while abroad began telematics services characterized by rescue and guidance

it is not difficult to see the gap by comparing typical systems at home and abroad. Typical domestic systems include Xiamen yaxun Qianliyan system, Xiamen yaxun ha chebao system, Xiamen yaxun Fangyuan, express system, Shenzhen segsegseg chesheng system, Beijing Lingtu integrated positioning service system, China Satcom Zhonghuan infinite system, Beijing Qihua taxi management system, and Chengdu Kaitian vehicle video streaming system

typical foreign systems, such as OnStar system of Ge in the United States, wingcast system of Ford in the United States, assist system of BMW in Germany, G-book system of Toyota in Japan, driving inno innovation system of ATX in the United States, T-Mobile traffic system of tegaron in Germany, and other system suppliers such as alpine, Delphi, Motorola, Visteon, Siemens VDO, etc

the remarkable feature of foreign system services or systems is to serve the users of vehicles. The service contents include traffic information/guidance, dynamic navigation, sos/roadside support, remote vehicle diagnosis, mobile Internet, speech recognition, mobile office and digital. According to the control mode, it is classified as follows: 1. Manual control and microcomputer servo control experimental machine; Broadcast/dvd video, etc. In China, due to the influence of technology, facilities, market and other factors, viss has not yet achieved the expansion of service objects from vehicle owners to vehicle users. It mainly includes vehicle information acquisition and control technology, adaptability of on-board electronic information equipment, system industry foundation and development environment, operation service mechanism and service facilities

to develop China's vehicle information service system, we need to expand the market achievements and experience of the vehicle industry, actively explore the growing demand of the automotive consumer market, and give full play to the advantages of operation services. In addition to further making the on-board equipment meet the requirements of automotive electronic information technology, we should pay more attention to the innovation and leadership of system information center technology, and solve the problems of center software architecture, intelligent protocol mechanism, information fusion processing and information sharing platform

optimize the infrastructure of system development, establish a linkage and coordinated operation mechanism, adjust advantageous resources through market behavior, and get the participation of automobile manufacturers to formulate relevant standards

China's car navigation products are moving towards multi-function integration

at present, the more mature regions of the global car navigation market include Europe, Japan and North America. Mainstream product types include traditional car audio, portable media + navigation, and telematics information terminal. In Europe, car audio navigation products and portable media navigation products each occupy a certain market share. Professor ITO, who plans to realize the actual utilization of new materials in cars in 10 years, is full of confidence. The front loading rate of new cars for car audio products is about 25%, and the market rate of portable media is slightly low, but it is growing rapidly. In Japan, car navigation products are mainly car audio products, and the front loading rate of new cars is close to 60%. North America can be removed from the main product by general methods; ② The green vehicle navigation of solvent is mainly telematics information terminal. Portable media and car audio have a small number of markets respectively. However, China has always been a car navigation market favored by insiders in the automotive and electronic industries, but the market response has been tepid. There is a lack of products suitable for automobile front loading

portable electronic map navigation is the main type of navigation products in China. Use pda+gps module to download free electronic map for service. There are uncertainties in the future development of this model, in which products are the main popular applications

the main problem lies in the misunderstanding of car navigation products and market, immature technology and high product price. Only focus on hyping the concept of GPS and navigation, ignoring the multi-directional needs of consumers for automotive electronics. The product type is single, and there is a lack of front-end products. Automotive manufacturers cannot directly participate, affecting market promotion. There is a lack of infrastructure related to navigation

by contrast, the product features of foreign automobile front loading are strict quality requirements and standards, guaranteed product quality, and multi-function integration. Radio function, media function, car bus interface, etc. are integrated with navigation function. The product is more humanized, retains the traditional knob and button operation, voice operation, and is organically combined with the car audio, which is in line with the power control technology of the car characteristics

the real-time release system of traffic information, integrated navigation and positioning, and the central navigation of telematics are several important applications of vehicle navigation technology worthy of our reference

in foreign markets, traffic information real-time publishing system is the most widely used. Including RDS system and TMC data in Europe and Dar in Japan
