The car navigation system has no longer meet the needs of the users with the development of technology, telematics as a new generation of autonomous vehicle navigation system, its function is more diverse and humane. In this thesis, in order to realize the vehicle terminal equipment of the telematics, on the basis of SAMSUNG’s S3C2440A processor and Microsoft’s Windows CE 5.0 embedded operating system, the structure of the hardware and software of the vehicle information terminal is introduced and analyzed, and the operating system and the related software are studied and developed. There are the following:1. In the beginning, the concept, the characteristics, the domestic and foreign development status of the telematics are introduced, then the significance of this thesis is pointed out. In addition, the framework and the service content of the system are given, and then the hardware structure, the scheme of operating system, and software composition of the vehicle terminal are described, which based on the analysis of the functional requirements of the telematics.2. BSP development, the components customization, the image file to download and SDK generation of the vehicle terminal operating system are introduced as a basis, then the transplantation of LCD and touch screen from 4.3 inches to 7.0 inches is realized, which achieved the proper display and operation of the system, based on OK2440 BSP. Meanwhile, the transplantation of SD card driver is studied, and the SD card can be read and write properly, so the necessary conditions for the systems to the support external storage is provided.3. The methods of the software to start with the operating system, desktop customization and optimization are studied to ensure that the operating system of practical and aesthetic. Meanwhile, for the problem of slow starting of operating system, the boot process of the operating system and the factors of slow starting are studied, and the several options of the improvement of the system boot speed are given, which provided some basic conditions for fast booting. 4. The serial port application, the control program of the camera and the bluetooth are developed separately in Embedded Virsual C++ 4.0, finally a serial port application of normal use, the playback of camera, camera images stored, and the control of the bluetooth are achieved. Meanwhile, on the basis of the realization of the normal communication of IIC in EVC++ 4.0, the FM control program is developed and the control of FM is achieved. Furthermore, the GPRS application is developed, then the makeing and receiving of calls, the sending and receiving of SMS, wireless Internet access and other functions of the GPRS module are realized. Lastly, the original data received from GPS is studied and the processing method of the data is given, and the realization of GPS positioning is achieved.In this thesis, the basic functions of the vehicle information terminal are implemented, which provided a terminal condition and the important foundation of the further development and improvement for the telematics.
