Patent number: 11920646Abstract: A method for operating a friction-locking shift element of a transmission of a motor vehicle includes actuating the friction-locking shift element for engagement according to a pressure versus torque characteristic curve. The pressure versus torque characteristic curve has a first characteristic point (a touch point) and a second characteristic point (a contact point), defines a first characteristic curve range between the touch point and the contact point having a first functional dependence, and defines a second characteristic curve range at or after the contact point having a second functional dependence. Once the touch point is reached, the friction-locking shift element begins to transmit torque mainly due to drag torques. Whereas, once the contact point is reached, the friction-locking shift element begins to transmit torque mainly due to friction between shift-element halves of the friction-locking shift element.Type: GrantFiled: June 21, 2023Date of Patent: March 5, 2024Assignee: ZF Friedrichshafen AGInventors: Philipp Kölbl, Michael Miller, Jonas Knör

Publication number: 20240068563Abstract: A method for operating a drive train (1) of a vehicle includes, in order to check the plausibility of an adapted charge pressure value, changing an actuating pressure of a starting component (7) corresponding to an adapted charge pressure value by an offset and ascertaining a resultant change in a torque of an electric machine (3). When the change in the torque of the electric machine (3) and the offset of the actuating pressure correspond to each other within defined limits, a plausible adapted charge pressure value is inferred. When the change in the torque of the electric machine (3) and the offset of the actuating pressure do not correspond to each other within the defined limits, an implausible adapted charge pressure value is inferred.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Inventors: Jonas Knör, Roland Jäger, Dennis Schaer, Philipp Kölbl, Michael Miller
