The operation stability of automobile is one of the important factors that affect the active safety performance, therefore, in order to obtain the well active safety performance, the research and appraisement of the operation stability of automobile has been a important topic on automobile at all times. The tire is one of important component of automobile. It get in touch with the road surface directly and mitigate the impingement with the suspension system together, in order to guarantee comfortableness and smooth finely in the running, to ensure the cohesion between the wheel and the road finely, to improve the performance of traction and breaking. Because of bearing the weight of automobile, the tire is attached importance to more and more. Since the 90s, the dynamics research of vehicles has started, when the main research is the characteristic of veer. Moreover, refer to the operation stability of aircraft, the attempt of vehicles movement model has started. Afterward, many research has been done in order to improve the vehicle dynamic performance, the influences of the suspension system, tires system, steering system, body system, breaking system and so on have been found. The purpose of this design is programming through Visual Basic when we import the relevant parameters of the vehicle dynamics perfo
