Therefore, in view of this situation, this paper puts forward modeling and object oriented programming method.</p><p> In this paper, according to the theory of object oriented modeling, the preliminary classification of vehicle dynamics and kinematics system for engine, transmission, brake system, steering system, wheel, suspension and body of 7 objects, and analyzes the properties and operation of the contained objects. Then, on this basis, the mathematical model is established. The suburb, to construct a 8 degree of freedom vehicle dynamics model: the program can be compared to the model verification, and according to certain rules of synthetic vehicle model can be used to
