Using virtual prototype and virtual reality technology, the research platform of vehicle handling stability was established, which includes established vehicle model, analysis and simulation, virtual experiment reappear and evaluation. A desktop virtual vehicle single-lane experiment had been developed for example, in which users can immerse in the virtual experiment environment and experience the unique effect using AGC-ViewerG stereo observation system. So driver, vehicle and environment constitute closed loop system in virtual environment and break through the previous evaluation way. It is an important way to study driver-vehicle-environment system.
