【摘要】 随着社会的快速发展以及人民生活水平的提高,汽车及相关产业在整个国民经济中的地位变得越来越重要。数字信息技术以及网络技术的高速发展,使人民在追求驾驶舒适性、便利性的同时,汽车的自动化、智能化和网络化也相应地被提上了日程。而车载系统作为汽车的一个不可分割的部分也必然面临着新的技术革命,智能的车载终端为驾驶员提供了集通信,多媒体播放,导航,娱乐为一体的多种服务。课题的任务是对嵌入式车载终端系统进行了软件与硬件的详细分析与设计,构建了一个基于ARM处理器和linux操作系统的车载终端,并在此基础上实现一些车载功能的应用。本文首先对车载终端设计和应用的研究现状和关键技术进行了详细的综述,深入分析了当前车载终端的存在的不足,提出了智能车载终端的软件和硬件的总体框架,设计了系统主要模块的硬件电路。其次,在研究嵌入式linux内核和文件系统的基础上,根据智能车载终端的特点,配置并设计了智能车载终端的linux内核,构建文件系统。最后分析做为一个基本车载终端的功能,并详细的阐述了部分车载功能具体实现过程,其中包括车内实时温度的显示,可视倒车,车载软电话,影音播放,与车载设备远程控制功能,并对每一个具体功能给出了相应的实验结果。论文的最后给出了课题的总结,并对以后的工作进行展望。
【Abstract】 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.
