温度依存性を考慮した車両運動解析用タイヤモデルの開発

抄録

The results of vehicle performance tests often vary depending on differences in the road surface temperature. It is believed that these changes can partially be attributed to the effect of tire surface temperature. The aim of this study is to develop a tire force model considering the dependence of tire surface temperature. The newly developed tire model is composed of two functions, the thermodynamic function that allows us to consider changes in the tire surface temperature and the force function that allows for the effects of tire surface temperature. The parameters of this model are identified using the measured data obtained with an indoor test facility. To prove the validity of the developed model, the surface temperature and the tire force values are predicted using this model. The simulation results agreed rather well with the experimental results.
