Abstract :
In this paper an estimation scheme is used to built using a robust differentiator and sliding modes. This allows us to identify the tire road friction. The estimations are produced in three cascaded steps of observers and estimators. The first produces estimations of velocities and accelerations. The second estimate the tire forces and the last reconstruct the friction coefficient. The application results show effectiveness and robustness of this method.
