Review and experimental evaluation of models for drivability simulation with focus on tire modeling

Abstract

Recent research showed a significant role of the interaction between traction and torsional vibrations on control design in passenger cars. However, there is a large diversity in the proposed models for drivability control design and validation. This paper gives an overview of popular models in drivability simulation and addresses the quantitative evaluation of these models in a wide range of operating points. Experiments have been performed with diverse excitation signals. Based on these experiments, a number of popular models for control design and validation are identified and compared. A new model is proposed, which will be shown to be a good trade-off between model accuracy and complexity. The results give a guidance for control engineers during the model selection process for either controller concept design, parametrization or validation.
