Abstract (english)

E-clutch systems allow for a conventional or electrified powertrain control system to operate the transmission clutch for expanded functionalities, reduced fuel consumption, and improved driving comfort. To facilitate E-clutch control system design and enable its simulation verification, an accurate E-clutch model is required. The paper presents a lumped-parameter model of E-clutch axial dynamics parameterized based on experimentally identified stress-strain characteristics of individual components of a disassembled clutch. An initial, simplified model is first presented and parameterized based on the overall, input-output stress-strain characteristics identified. While the experimental validation results show that the initial model provides a satisfactory prediction of the clutch torque static curve, the prediction of the release bearing force static curve is less satisfactory, thus indicating a potential for further model improvements. Therefore, new, more detailed versions of the model containing individual component stress-strain characteristics are proposed and experimentally validated. The validation results indicate considerable improvements in the normal force static curve prediction accuracy when using the extended model.
