Design And Realizing Of Mobile Terminal Of Embedded Vehicle Based On ARM

With the rapid development of society and the improvement of people's living standards, automobile and related industries in the status of the entire national economy become increasingly important. The information technology and network technology enabled driving comfort and convenience to be pursuit. At the same time, car automation, intelligent and network accordingly were put on the schedule. As an inseparable part of the car, vehicle system inevitable faces a new technological revolution, intelligent vehicle terminal provides variety services for drivers such as communications, multimedia playback, navigation, and entertainment.The task of the subject is to analysis and design on the software and hardware of vehicle terminal systems. Based on ARM processor and Linux operating system developed a vehicle terminal. On this basis, to obtain achievement of the applications of some vehicle functions.Firstly, this paper reviewed on the research status of vehicle terminal design and key technology. Then analyzed about the shortcomings of current vehicle terminals, and proposed the overall software and hardware framework of intelligent vehicle terminal. Then the main modules circuit of the hardware system was designed.Secondly, According to the characteristics of intelligent vehicle terminal, based on the research of embedded Linux kernel and file system, designed an intelligent Linux kernel of vehicle terminal, and constructed file system. At last, analyzed the specific working procedure for basic application programs of a vehicle terminal, including real-time display of in-car temperature, visible backing, in-vehicle softphone, media playback, remote controlling of in-vehicle device. Attached experiment results on each specific function. Finally, the paper topics are summarized, and future work are prospected.
