| Abstract: | An auto fully virtual instrument cluster program was proposed based on QNX hardware acceleration and software control.In order to shorten the HMI development cycle,the technology based on fast HMI prototyping and logic simulation was introduced.The module of real-time layer rendering was designed under the software control,so as to display the huge info dynamically.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 instantaneous vehicle info more smooth and realistic. |
