Based on the above analysis, combined with the application of based on vehicle networking service analysis and the use of existing network system can be provided to the car in the analysis of various means of communication, car networking system from the technical level to solve the problem of the following five aspects:
(1) sensor network and related data communication, multimedia sensor network technology application in car networking consists of two parts, the first part refers to the on-board sensors network and related data communication: the second part refers to the road sensor network, responsible for road transportation information, sensor network and related vehicle related data such as data communication, in the first part, automotive sensor networks and sensor networks can be further divided into the van and car sensor network, vehicle driving personnel to be able to connect related equipment car sensor networks for vehicle related data information, mainly is the attribute information of the vehicle and static and dynamic information, to rescue vehicles, car networking applications such as intelligent monitoring service provides the underlying data information, and outside sensor network is used for induction sensor networks outside the state of the environment, through the sensor network for data exchange with the outside can improve the driving safety and provide relevant information of auxiliary driving,
(2) the source of vehicle terminal system development platform, the current automotive service system architecture determines the brand of car service system can provide service for the brand terminal users, and can't realize the cross-platform service,
Connected to the terminal (3) car voice control, no matter how good the car terminal adopts touch control, touch terminal system in the process of drivers driving is very dangerous, so the voice control technology is particularly important in the car networking system, as a matter of fact, the company developed voice assistant (Siri) has been in a new generation of apple products to carry out specific services, voice control is no longer far-fetched, completely can be used in car networking systems, an ideal voice control can realize the vehicle driving personnel to control the car terminal sends by voice command, this is the most suitable for vehicle so natural to have experience of the application of using the characteristic of mobile environment, through the voice control of mature technologies such as apple, the analysis of the development of voice assistant (Sin), voice control relies on the powerful network database can be found and cloud computing technology, so the car voice control technology development depends on the reasonable application of wireless communication technology in the network system,
(4) the integration of the intelligent transportation platform construction and service center, car - is one of the main purpose of the Internet, in the true sense of intelligent transportation, transportation participants through the on-board vehicle network terminal equipment, to provide intelligent transportation platform around the real-time traffic information, when intelligent transportation platform after get the data and related processing, can to ride personnel to provide real-time traffic information, weather information and other related service information, has been put into use of the automaker's service center with ford's SYNC, gm's OnStar, Toyota G - Book and nissan CarWings + chi heng, but these services center is only to specific traffic managers use, there is no connectivity between each other, in fact, most of these services center functions are very similar, can be integrated with each other in - -, at the same time, involved in road, most of the functionality of the vehicle and intelligent transport platform repetitive, through service integration, on the one hand, can avoid redundant construction, it also can make the car get better more valuable services,
(5) wireless communication technology integration and intelligent gateway technology, generally speaking, the vehicle will be in the following three kinds of environment, vehicle ad-hoc network environment, the mobile communication network and wireless local area network environment, and so on hardware within the vehicle network terminal need to integrate respectively corresponding to support data transceiver module, at the same time, the software in a particular area of vehicle may in several environment: interchange, which requires an integrated signal strength, bandwidth, data rate calculation factors such as the selection algorithm, adaptive to achieve optimal network access options, and, because the car network terminals and a number of different network connection, and the network communication protocol, data format or language difference is very big, so the car network terminal be achieved between the different network interconnection on the transport layer, realize the function of a kind of "intelligent gateway",
