• In this paper a real-time estimation method is presented for identifying the tireroad friction coefficient.Taking advantage of the Magic Formula Tire Model, the similarity technique and the specific model for the vehicle dynamics, a reduced order observer / filtered-regressor-based method is proposed.The proposed method is evaluated on simulations of a full-vehicle model with an eight state nonlinear vehicle / transmission simulation model and a nonlinear suspension model.It has been shown through simulations that it is possible to estimate the tire-road friction from measurements of engine rpm, transmission output speed and wheel speeds using the proposed identification method.It would be useful to incorporate the tire-road friction information into a vehicle collision warning algorithm.The proposed method can be used as a useful option as a part of vehicle collision warning / avoidance systems and will be useful in the implementation and adaptation of the warning algorithm since the tireroad friction can be estimated only using RPM sensors.
