“…The brush tire model assumes the tire carcass to be rigid and the tread surface to be a row of elastic bristles. Then, by analyzing the forces acting on the bristles during ground contact, the tire forces are determined [12]. Later, scholars began to study the mechanical properties of tires using the brush model.…”

Electric vehicles, with their distinct power systems, weight distribution, and power control strategies compared to traditional vehicles, influence the pressure distribution in the tire contact area, thereby affecting the estimation of road adhesion coefficient. In electric vehicle research, tire adhesion coefficient serves as a measure of the frictional force between the vehicle and the road surface, directly impacting the vehicle’s handling performance. The accurate estimation of the adhesion coefficient aids drivers in better understanding the vehicle’s driving state. However, the existing brush models neglect differences in ground pressure distribution along the width direction of tires during tire camber, potentially leading to inaccuracies in adhesion coefficient estimation. This study proposes a camber brush tire model that considers the width-direction pressure distribution characteristics, aiming to enhance the accuracy of adhesion coefficient estimation under camber conditions. Experimental comparisons between the improved and original models reveal a significant enhancement in estimation precision. Consequently, the findings of this study provide valuable insights for deepening our understanding of tire camber dynamics and for designing control systems for electric vehicles, thereby improving vehicle stability and safety.

“…However, this kind of model is powerless when tire test data is absent. The theoretical tire model, like Brush Model [3], can describe the tire characteristic in essential and has the ability for model prediction. However, this kind of model has a long way to practical application due to without considering the tire carcass deformation and the load dependence.…”

The tire lateral force is essential to the vehicle handling and stability under cornering. However, it is difficult for engineers to get the tire lateral force under high loading condition due to the limitation of loading ability for most tire test machine in the world. The widely used semi-empirical tire lateral force models are obtained by curve-fitting experiments data and thus unable to predict the load dependent lateral force. The objective of this paper is to predict the tire lateral force under high-load condition based on the low-load tire data.The nonlinear characteristics of the tire cornering stiffness with the load are greatly affected by the tire carcass compliance. In this paper, a theoretical tire lateral model was built by considering carcass complex deformation. Combined with the relationship between the half-length of the tire contact patch and the load, the non-linear characteristics of the tire cornering stiffness with load were obtained. So the tire lateral force in the linear range under high-load condition was captured. As for the nonlinear range, the tire lateral force under high-load condition was acquired by deriving an empirical friction model dependent on load and slip velocity. The low-load tire test data was used to estimate model parameters. The lateral force prediction accuracy was verified by the high-load tire test data.
