Abstract: In order to meet the need of the test platform for the automobile industry and the professional education of vehicle engineering, this paper explored the relevant experimental research and mathematical modeling of vehicle automatic driving, using 3D model to link and share data with the external equipment so as to realize the human-computer interaction between the virtual model and the real driving simulator. Regular automatic driving platform is a test platform to realize the movement of vehicles in virtual reality environment on the basis of ensuring the hardware function. At the initial stage of this project, the Unity3d engine is used for modeling, Easyroads and other materials are used for modeling roads, buildings and road facilities. On this basis, the Thrumaster T150 force feedback steering wheel is used to realize human-computer interaction. Experiments show that the model can meet the needs of vehicle teaching experiment.
