On road testing of control strategies for semi-active suspensions

An original data driven approach is proposed for the characterization of two-wheel vehicles suspension systems with regard to the comfort and vehicle handling. The proposed methodology includes a low cost measurement set-up, data analysis in both time and frequency domain and the introduction of model-free synthetic indexes in order to experimentally compare the on-road behavior influenced by different damping characteristics for the suspension system. The method is applied to the on-road verification of the riding comfort assured by different control strategies for semi-active suspensions.
