Abstract


Advanced automotive research and development become a national competition for one of the hot hot research focused on simulation of vehicle dynamics model. However, there is widespread simulation analysis technology can not replace running an experiment to evaluate the performance of the vehicle, one important reason is that the researchers can not get immersed immersive sense of the scene. With computer graphics, images, 3D modeling, computer vision and other related technologies, the emergence of virtual reality in this emerging discipline. It integrates computer graphics technology, computer simulation technology, artificial intelligence, sensor technology, display technology, network parallel processing technology, the latest results of the development is a high-tech computer-generated simulation systems, this technology is characterized by computer produce an artificial virtual environment, this virtual environment is constituted by the computer graphics 3D digital model and prepare the computer to generate a visual experience-based, including auditory, tactile perceivable integrated artificial environment, so that the visual produce a feeling of immersion in the environment, can be directly observed, the operation, touch, detects the ambient and internal changes of things, and can occur with \com \First create the entity and the sum of the visual design performance design as the core technology of the vehicle dynamics virtual prototype, then create a virtual prototype of this virtual reality through VR technology vehicle dynamics simulation model to arrive in the operation of the vehicle and the road surface and vehicle mechanics relationship between the parts themselves. This method can overcome the researchers were not able to get the vehicle running immersive sense of the scene. Among the many virtual reality modeling and simulation tools, MATLAB is a high performance, visual modeling, realistic simulation of the software. Based matlab7.1 the V-Realm Builder toolkit built Skoda (Skoda) vehicle dynamics model to the virtual reality scenes (the text referred to SVDV), combining Simulink to create a dynamic system, and access to the virtual world for vehicle dynamics simulation, analysis . Simulation results show that the virtual reality scenes can accurately and realistically simulate the real dynamics of the vehicle is running, for the realization of the virtual reality technology in the design and control of the vehicle provides a theoretical basis.
