摘　　要：提出基于QNX硬加速的软控车载全虚拟仪表平台方案,引入快速HMI原型设计和逻辑仿真测试技术,以缩短人机交互界面开发周期;设计软控模式下图形元素实时分层渲染模型,实现庞大信息的动态显示;采用基于OpenGLES2.0的GPU硬加速技术提高图形渲染帧率。实验表明:该方案不仅能实时处理车辆内部模块的大量信息,而且能平滑逼真地动态显示瞬时车况信息。An auto fully virtual instrument cluster program was proposed based on QNX hardware acceleration and software con- trol. In order to shorten the HMI development cycle, the technology based on fast HMI prototyping and logic simulation was intro- duced. The module of real-time layer rendering was designed under the software control, so as to display the huge info dynamical- ly. The GPU hardware acceleration technology based on OpenGLES2.0 was used to improve the frame rate. Experiments show that , this program can not only process a huger info, comes from inner modules of the vehicle, but also can dynamically display the in- stantaneous vehicle info more smooth and realistic.
