Tire-Road Friction Coefficient Estimation Using a Multi-scale, Physics-based Model
The interaction between a tire and road surface is of critical importance as the motion of a car in both transient and steady-state maneuvers is predicated on the friction forces generated at the tire-road interface. A general method for predicting friction coefficients for an arbitrary asphalt …

Model Based Estimation of Road Friction for Use in Vehicle Control and Safety
The road surface friction is an important characteristic that must be measured accurately to navigate vehicles effectively under different conditions. This parameter is very difficult to estimate correctly as it can take up a value from a broad spectrum of possibilities and the knowledge of this …

The Application of Intelligent Tires and Model Base Estimation Algorithms in Tire-road Contact Characterization
… knowledge about the abrupt changes in pavement friction and poor performance of the vehicle stability, traction and ABS controllers on the low friction surfaces are the most important factors affecting car crashes. Due to its direct relation to vehicle stability, accurate estimation of tire-road …

Development of H∞ control strategy for a multi-wheeled combat vehicle
… standard events are used for testing. Two road friction coefficients are used, 0.35 and 0.85 µ at speeds between 40 and 100 kph. The proposed control system is able to greatly improve vehicle stability at high speeds and/or low friction and increase maneuverability at lower speeds and/or …

Intelligent Tire Based Tire Force Characterization and its Application in Vehicle Stability and Performance
… The interaction between the tire and the road surface determines the vehicle's ability to accelerate, decelerate and steer. Having information about this interaction in real-time can be very valuable for the on-board advanced active safety systems to mitigate the risks ahead of time and …

Road Surface Measurement and Multi-Scale Modeling of Rubber Road Contact and Adhesion
A major challenge in tire, as well as in road engineering, is to understand the intricate mechanisms of friction. Pavement texture is a feature of the road surface that determines most tire-road interactions, and can be grouped into two classes: macro-texture, resulting mainly in the hysteretic …

Development of an Intelligent Tire Based Tire - Vehicle State Estimator for Application to Global Chassis Control
The contact between the tire and the road is the key enabler of vehicle acceleration, deceleration and steering. However, under the circumstances of sudden changes to the road conditions, the driver`s ability to maintain control of the vehicle maybe at risk. In many cases, this requires …

An Interdisciplinary and Probabilistic Treatment of Contemporary Highway Design Standards
… simulations, such as the coefficient of friction. This is a questionable practice when operating on the precipice of compromised safety. Thus, the second part of this work probabilistically examines the chance of handling loss given the amount of tire-road friction and driver …

A Novel Road Grip Estimation Method Using a Vehicle as a Probe
Winter weather road maintenance has been a topic of discussion among many state Departments of Transportation (DoT) within the US and numerous countries across the globe. Several research efforts have been conducted with the common goal of making this seasonal activity more efficient and/or …
