Dynamic Friction Models for Longitudinal Road/Tire Interaction: Experimental Results
نویسنده
چکیده
A new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles is validated via experiments with an actual passenger vehicle. Contrary to common static friction/slip maps, this new dynamic friction model is able to accurately capture the transient behavior of the friction force observed during transitions between braking and acceleration. A velocitydependent, steady-state expression of the friction force vs. the slip coefficient also allows easy tuning of the model parameters by comparison with steady-state experimental data. Our experimental results validate the accuracy of this new tire friction model in predicting the friction force during transient vehicle motion.

Dynamic Friction Models for Road/Tire Longitudinal Interaction
In this paper we derive a new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles. The model is based on a dynamic friction model developed previously for contact-point friction problems, called the LuGre model [7]. By assuming a contact patch between the tire and the ground we develop a partial differential equation for the distribution of the fr...

متن کاملExtension of the Lugre Dynamic Tire Friction Model to 2d Motion
An extension of the LuGre dynamic friction model from longitudinal motion to longitudinal/lateral motion is developed. Applying this model to the motion of a tire we derive a model for tire-road contact forces and moments. A comparison of the steadystate behaviour of the dynamic model with existing static tire friction models is also presented. This comparison allows one to determine the values...
متن کاملStatic Tire/Road Stick–Slip Interactions: Analysis and Experiments
Tire/road interactions play a critical role in safe operation of ground vehicles. This paper presents the modeling, analysis, and experimental studies of stick–slip interactions between the stationary tire and the firm road. A semi-analytical model is first proposed to predict the normal force distribution on the tire contact patch. A beam–spring network modeling approach is then used to captur...

In-situ sensing the tire–road interactions such as local contact friction force distributions provides crucial information for building accurate friction force models for vehicle safety control. In this paper, we report the development of an embedded, flexible local force sensor for measuring the tire local friction forces and their distributions. A new pressuresensitive, electric conductive ru...
