Abstract

Recent research showed by theoretical analysis a significant role of the interaction between traction and low-frequency torsional vibrations (known as driveline shuffle) on anti-jerk controller design in passenger cars. This paper addresses the experimental validation of these findings in a wide range of operating points. Various experiments have been performed with a plug-in hybrid electric vehicle. Several excitation amplitudes have been applied at different vehicle speeds and driving conditions. As a result, the dependency of the driveline shuffle characteristics is quantified in this study. These results are the first step towards a guideline for control engineers during the model selection process for either anti-jerk controller concept design, parametrization or validation. Based on these results a linear parameter varying model (LPV) is proposed.
