摘　　要：为了优化汽车仪表系统性能,提高系统智能化、人车交互界面友好度,以ARM微处理器S5PV210为控制核心设计了一款汽车智能仪表系统。该系统以嵌入式实时操作系统Linux为软件平台,结合CAN现场总线技术,并采用开放源代码的图形界面库QT开发仪表终端应用程序。经实验验证,系统性能得到了改善。In order to optimize the performance of the automotive meter system, improve the friendliness degrees of man-vehi- cle interaction interface, and make the system become intelligent,a type of automotive intellectual control meter system is designed in this paper. ARM processor SSPV210 is used as the core of hardware platform and embedded Linux operating system is used as the core of the software platform. The CAN bus is one of the widely applied fieldbus and used in the intellectual control meter system.Additionally,the open source graphical user interface library QT is used to develop the terminal application program. The results of experimental verification shows that the performance of the system is improved.
