Publication number: 20230246524Abstract: A device for determining a torque in a drivetrain of an at least partially electrically operated motor vehicle is provided, having a first electric motor with a first rotor rotatably mounted in at least two rolling bearings spaced in the axial direction. The first rotor is operatively connected to at least a first vehicle wheel to be driven by the first electric motor. The first rolling bearing has a first angular position sensor and the second rolling bearing has a second angular position sensor, the sensors each generating a signal that represents the angular position of the first rotor at the particular bearing point. The signals are transmitted to a vehicle controller, in which the torque of the first electric motor applied to the first rotor is determined from the difference between the angular positions and is provided to control the motor vehicle.Type: ApplicationFiled: May 28, 2021Publication date: August 3, 2023Applicant: Schaeffler Technologies AG & Co.

Patent number: 8712658Abstract: A method for adapting a contact point of a clutch in a drivetrain of a motor vehicle, wherein the clutch is moved by an actuator and the influence of the movement of the clutch on a rotating electric motor is evaluated. A method that is simple and quick to carry out, a clutch torque and/or an actuator path close to the contact point is obtained from a characteristic curve of the clutch representing the relationship of an actuator path to a clutch torque and is set at the clutch. Subsequently the associated actuator path and/or the clutch torque is measured from the clutch influenced by the actively operated electric motor, where the clutch torque read from the characteristic curve and the actuator path measured at the clutch and/or the actuator path obtained from the characteristic curve and the measured clutch torque form the current contact point position of the clutch.Type: GrantFiled: October 25, 2012Date of Patent: April 29, 2014Assignee: Schaeffler Technologies AG & Co.

Patent number: 8167774Abstract: A process for controlling a twin clutch transmission with two partial drive trains with respectively a friction clutch interposed between an internal combustion engine and the partial drive train is provided. If the transmission capacity of a friction clutch falls below the engine torque, engine intervention takes place. If the clutch temperature rises further above a default value, an emergency operation is initiated, in which the affected partial drive train is deactivated by opening the affected friction clutch, a preselection strategy used in the other partial drive train is changed and the other partial drive train is activated.Type: GrantFiled: April 3, 2009Date of Patent: May 1, 2012Assignee: Schaeffler Technologies AG & Co.
