Robustness study of the road profile estimation technique under uncertainty

Abstract

This paper studies profile estimation of a road. The prediction has been achieved using the Independent Component Analysis Method (ICA). The vehicle dynamic responses were calculated 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.
