Methods for identifying the tire-road friction coefficient are proposed and evaluated on an eight state nonlinear vehicle/transmission simulation model with a Bakker Pacejka's formula tire model. Vehicle tests are performed on dry and wet roads to verify the performance of the methods. Through simulations and vehicle tests, it is shown how the RPM sensors can be used with observer based identification methods to estimate the tire-road friction from measurements of engine rpm, transmission output speed and wheel speed.
