Frédéric Hellas - Determination of Heuristics for Riding Comfort

This thesis is divided into three parts.

A first one is an overview of the existing methods to analyze riding comfort.

The second one is the analysis of measurements obtained from an instrumented car tested on calibrated roads where differents shock absorbers were tried. The ride engineer provides a subjective classification of the different dampers. The aim is to target the most important signals correlating to the subjective assessments. Different mathematical tools are investigated for signal processing (Fourier, RMS, Wavelets).

The third part consists of an automatic evaluation of ride comfort from measured data, including the validation of the method on a car.
