Abstract
At least a method is provided learning a characteristic filling volume of a hydraulic clutch. The method includes, but is not limited to applying a pressure pulse to the hydraulic clutch when the clutch is in a disengaged state and determining an inflection event at an input or at an output of a torque path in which the hydraulic clutch is situated. A characteristic filling volume of the hydraulic clutch is derived from the determined inflection event. Furthermore, a method is provided for learning a characteristic return spring pressure of the hydraulic clutch, for engaging the hydraulic clutch and corresponding devices for carrying out these methods.
