Vehicle behavior is determined by suspension system and force generated on a ground contact surface of the tire. Study on suspension systems had been carried out many times and the compliance characteristics can be analyzed using commercial programs. However, the analysis of vehicle behavior by the forces and the torque generated in tire is based on result of the tire test or the model provided by the commercial programs. These tire models are used to calculate the forces acting on the tires, and there are models that consider physical characteristics such as brush tire models or UA tire models. On the other hand, there is a black box model that obtains the forces and torque from input/output relationship without physical characteristics such as MF tire model.
In this paper, a brush tire model was studied. This model is the basic tire model and it uses a small number of tire characteristics. It can help easily understand the physical phenomena acting on the tire and requires only a few times on analysis than other tire models. However, this model is insufficient to express the degrees of freedom about the forces and torque. So, it can’t accurately fit test data. In order to resolve these problems, the degrees of freedom were improved by applying the kinetic friction characteristic to the existing model using only the maximum static friction. In addition, to improve the degrees of freedom of the self-aligning torque, parameters were added to the tire characteristic coefficient
