The automotive dashboard reflects a variety of process parameters. Designing the virtual automotive dashboard system is important for teaching and research. The overall design program was proposed by analyzing the function of automotive dashboard. The virtual dashboard interface and the performance simulation test system were developed based on VB, which can collect & transmit signal between PC and microcontroller. The engine speed, travel speed, temperature and mileage information were displayed on the PC interface by the calculation model. Operating the buttons can simulate the steering instructions. The experiment shows that the system works properly and has simulation results for the visual automotive dashboard.
