The rolling resistance and the effective radius of a tyre are two important characteristics that are very useful for vehicle diagnosis and wheel monitoring systems. This paper proposes to consider the physical model of rotational and longitudinal dynamics of the wheel and to apply a variable structure observer for an on-line estimation of these quantities using measurement of wheel angular velocity,...
This paper proposes an application of a variable structure observer for wheel effective radius and velocity of automotive vehicles. This observer is based on high order sliding approach allowing robustness and finite time convergence. Its originality consists in assuming a nonlinear relation between the slip ratio and the friction coefficient and providing an estimation of both variables, wheel radius...
