摘要:AbstractIn this paper a physics-based overall model of a hybrid powertrain equipped with a stepped automatic gearbox is derived. On the one side, the model approach serves as plant model for the development of new control strategies for clutch-to-clutch gear shifts. On the other side, it provides important insight into the dominant dynamic effects. This study focuses on wet clutches and their hydraulic actuation as well as a compact mathematical representation of the planetary gear train. The use of a modified elasto-plastic friction model allows for a physical representation of the friction torque occurring during gear shifts without the need of structural model changes.
