Design And Research Of Vehicle Multimedia System Based On Telematics

In recent years Internet technology develops rapidly, the information sharing between people has reach the level of the seamless connection. As the development of automobile industry, car is not only a transport for people. With constant progress of information and communication technology, the cars will be out of the original narrow space for people to realize in the process of driving information with the outside world Unicom important node. Under this background vehicle multimedia system based on Telematics to get the attention both at home and abroad, and gradually increase the investment of the development. Domestic and foreign many car makers are developed based on Telematics vehicle infotainment system.This article is based on the actual project development as the research background, the project aim is to develop a set car multimedia system based on remote cloud service platform, through the establishment of cloud services platform, make the car multimedia system and other vehicle control module through the onboard wireless terminals and cloud services platform for data communication. Vehicles and drivers can communicate with third-party service providers to get the related services through wireless communication function of cloud services platform. This article finished at the system frame and function definition phase which is at early stage of project. At this stage project need to finish complete car networking function definition, the vehicle terminal system architecture as well as car networking technology architecture of cloud service platform, the above content are the theoretical basis of the project development.This article mainly expounds car networking system from three aspects:First of all, expounds the development background of this article for the car networking, and the research status at home and abroad are summarized, combined with domestic and foreign car makers for networking definition. Based on the actual product, the planning a multimedia system function definition based on remote information service, new functions are combined with Internet which are account management, security(remote control), call center, online navigation function, at the same time as cloud services platform have the characteristics of great data analysis ability, feasibility analysis of driving behavior model is set up.Then, this article which is based on the car networking system function definition and according to the mainstream car network based system framework NGTP2.0 cloud services platform, put forward its cloud service platform. And put forward the car networking hardware and software overall solution. On hardware, calculating the system server hardware performance requirements and put forward car terminal module hardware design scheme. On software, present design proposal for cloud services account registration and certification processes, terminal applying information service routing process, and driving behavior analysis modelFinally, based on the development of the overall project schedule, this article set actual hardware sample car terminal as the core, set the car networking remote communication system simulation test bench, the bench on the remote control, fault remind and vehicle status functions such as real-time communication test, obtained the actual times of remote communication test data, it is acceptable for the customer.
