| Résumé : | For a new kind of automatic transmissions adopting clutch-to-clutch shift control technology, a clutch pressure observer is proposed to improve the estimation accuracy during the shift torque phase. The observer is designed in the concept of input-to-state stability. Lookup tables, which are widely used to represent the complex nonlinear characteristics of engine systems, appear in their original form in the designed reduced-order observer, and the torsional stiffness of the drive axle shaft is considered in the model-based design procedure to improve the estimation accuracy. Finally, the designed pressure observer is tested on an amesim powertrain simulation model. Comparisons with an observer without considering the drive shaft compliance are given as well. |
