ABSTRACT
This paper studies profile estimation a road. The prediction has been achieved using the
Independent Component Analysis Method (ICA). The vehicle dynamic responses were cal-
culated for different road profiles which were defined using an ISO norm. The robustness
of this method was proven by implementing the stochastic Monte Carlo (MC) technique in
the presence of inevitable uncertainty parameters simultaneously associated with the vehicle
mass, spring stiffness and damping for different vehicle speeds and wind values. Convergence
was assessed when comparing real profiles to simulated ones. The obtained results prove the
efficiency of the ICA in estimating the profile variabilities under uncertainties.
