THE USE OF RANDOM SEQUENCES IN THE IDENTIFICATION OF VEHICLE DYNAMICS

This report describes a method of quantifying the dynamic response of a vehicle to steering inputs in the form of transfer functions constructed from recorded time series data. A brief review is given of some of the ways of identifying vehicle dynamics and the reason for choosing the method of random data analysis is developed. Results are given that check the "suite" of computer programs which compute the vehicle frequency response and the pole-zero pattern of the transfer function. It is shown that changes in vehicle parameters of speed and type characteristics are reflected in migrations of the poles and zeros and that results are repeatable to practical engineering limits. These techniques contribute to an understanding of vehicle dynamics (which optimize the man/vehicle relationship) and could find a practical use in the design of new vehicles.(a) /TRRL/
