Friction Prediction and Application to Lateral or Longitudinal Slip Force Prediction

The empirical or semi-empirical model is widely used for vehicle simulation because of its high accuracy but relies on massive experimental data tire force and moment. Therefore, mechanical prediction great significance to improve modeling efficiency reduce costs. Typical methods models based normalization presented by Pacejka Radt assume that different loads could be close one normalized curve, it not always accurate enough predict under pure slip conditions there no mention friction methods. In the paper, a theoretical considering deformation belt/carcass established, which lays foundation model. A method separation from test proportional assumption longitudinal lateral peak coefficient between target reference are proposed, results show this acceptable. Finally, according assumption, new validated comparison with data. It shows proposed has good capability satisfactory accuracy.
