A novel Hilbert-transform-based parameter identification method for time-varying vehicle dynamics under harmonic conditions is proposed. In order to build accurate simulation models, system parameters related to its linear singletrack model need to be estimated based on the experimental data. Unlike other parameter identification methods, Hilberttransform- based approach is capable of identifying the timevarying parameters with acceptable accuracy within the range of linear lateral dynamics. Besides, it has a powerful advantage that any time-varying properties of vehicle dynamics parameters even within a small time interval can be effectively identified and described with this method. Finally the method is applied to validate a complicated simulation model of a car-trailer combination obtained with IPG CarMaker software using the experimental data.
