摘要
为了提高汽车仪表的安全性、实时性,提升三维仪表的视觉效果,增强人机交互界面的友好度,设计了一种基于ARM的电动汽车虚拟仪表系统。采用以ARM处理器IMX6SOLO为核心的硬件平台和以嵌入式QNX系统为核心的软件平台,并用Kanzi进行仪表的界面设计。经试验验证,该仪表系统具有开机快、反应灵敏、三维效果强烈,同时提高了仪表开发效率和人机交互性能,缩减了仪表开发周期。
To improve the safety,the real-time performance,and the visual effect of 3 D automobile instruments,a virtual instrumenting system for electric vehicles(EV)based on ARM has been designed as a friendly human-computer interaction interface.The hardware platform consists of an ARM processor and IMX6 SOLO.The core of the software platform is an embedded QNX operating system.The interface design of the instrument is based on Kanzi.The tests verified that the instrument system has the advantages of quick start-up,sensitive response,distinct 3 D effect,and friendly human-computer interaction performance.The designing method proposed in this work improves the developing efficiency of the instruments,as well as reduces the time consumption of the designing period.
