GPS Based Real-Time Tire-Road Friction Coefficient Identification
TLDR
In this paper, the authors developed a real-time tire-road friction coefficient estimation system for snowplows that can reliably estimate different road surface friction levels and quickly detect abrupt changes in friction coefficient.Abstract:
This project concentrates on the development of real- time tire-road friction coefficient estimation systems for snowplows that can reliably estimate different road surface friction levels and quickly detect abrupt changes in friction coefficient. Two types of systems are developed - a vehicle-based system and a wheel-based system. The vehicle-based friction measurement system utilizes vehicle motion measurements from differential global positioning system (GPS) and other on-board vehicle sensors. The wheel-based friction measurement system utilizes a redundant wheel that is mounted at a small angle to the longitudinal axis of the vehicle. Complete technical details on the vehicle-based friction measurement system are presented in this report. Compared to previously published results in literature, the advantage of the vehicle-based system developed here is that it is applicable during both vehicle acceleration and braking and works reliably for a wide range of slip ratios, including high slip conditions. The system can be used on front/rear-wheel drive as well as all-wheel drive vehicles. Extensive results are presented from experimental results conducted on various surfaces with a winter maintenance vehicle called the Safeplow. The experimental results show that the system performs reliably and quickly in estimating friction coefficient on different road surfaces during various vehicle maneuvers.read more

Slip-based tire-road friction estimation
TL;DR: An approach to estimate the tire-road friction using only the wheel slip, that is, the relative difference in wheel velocities, is presented and an adaptive estimator is presented for a model linear in parameters, designed to work for periods of poor excitation, errors in variables, simultaneous slow and fast parameter drifts and abrupt changes.
