摘要
设计了一种采用ARM和Linux架构方案的汽车虚拟仪表系统,仪表通过CAN总线以及硬线接口与车辆接口连接。介绍了CAN数据信息采集显示系统设计,嵌入式系统平台双MCU构建和人机界面设计,系统可以实现汽车虚拟仪表系统所需参数采集、处理、计算以及结果显示、存储功能。实验结果表明该系统能够达到汽车虚拟仪表的功能设计要求。
A vehicle virtual instrument system is designed with ARM and Linux architecture.The instrument send and receive data through CAN bus and hard line.The design of CAN data acquisition and display system is introduced.Embedded system plat-form construction and human-machine interface design,the system can complete the acquisition, process, calculation, display and storage of the parameters of the vehicle virtual instrument system.The experiment results show that the scheme meets the design requirements of virtual instrument.
