基于Android车载虚拟仪表人机界面设计稿毕业设计稿.docVIP

摘 要 车载虚拟仪表人机界面，是驾驶员获取汽车工况数据的主要界面，便于驾驶员实时全面地掌握汽车工作状态，有效地与汽车进行人机交互，对保障汽车安全稳定的行驶有着重要意义，目前普遍使用的是Windows CE和Linux操作系统。Windows CE操作系统功能稳定，有完善的技术支持，但价格昂贵、源代码封闭、网络可利用资源较少；Linux操作系统的最大优势在于免费和开源，是车载信息显示系统的主流操作系统，但其并不是基于移动设备开发的，不能完全满足移动设备的需求。Android是Google开发的一款基于开源操作系统Linux的开放、开源移动平台，对于目前主流的嵌入式平台支持良好，Android系统的优越性能己在多款移动设备上得到验证。它包括操作系统用户界面和应用程序而且不存在任何以往阻碍移动产业创新的专有权障碍。文中提出利用Android作为车载虚拟仪表软件开发平台，在Android提供的应用程序框架上来实现虚拟仪表的人机界面。Abstract Vehicle virtual instrument interface, is the main interface driver gets condition data of automobile, it is convenient for the driver to real-time to grasp the working conditions of automotive, effective human-computer interaction and the automobile, has the vital significance to guarantee safe and stable running of the car, at present the widespread use of Windows CE and the Linux operating system. Function of Windows CE operating system stability, a sound technical support, but the price is expensive, the source code, can use fewer resources closed network; maximum advantage of Linux operating system is free and open source, is a vehicle information display system of mainstream operating system, but it is not based on the mobile device development, cannot meet the demands of mobile equipment demand. Android is the development of a Google based on open source mobile platform, open source operating system Linux, for the current mainstream embedded platform support, superior performance of the Android system has been validated in a variety of mobile devices. It includes the operating system user interface and application program and there is no past hinder the mobile industry innovation proprietary obstacles. In this paper using Android as the virtual instrument software development platform,application framework provided by Android to realize virtual instrument interface.
