When simulating vehicle dynamics, it is important to express the interaction between the tire and the road surface accurately because the behavior of the vehicle depends on the force and the moment applied to the tire. MF (Magic Formula) tires are mainly used in most vehicle dynamics SW to express tire characteristics that show nonlinear and complex behavior against the load applied to tires under various contact conditions. This paper is proposing a method to utilize tire models effectively in the development stage of vehicle performance. The first method is to immediately extract major tire characteristics from the tire model, and the second is to find a model parameter combination that satisfies target tire characteristics by applying an optimization technique. The technology was made efficiently available to anyone through application development. Also, a change in vehicle performance due to changing of tires was explained through a contribution analysis. It is expected that the method developed in this paper will be used frequently in assessing vehicle performance in the development stage. |
