Patent number: 12609643Abstract: The present disclosure relates to a method for estimating a torque of an electric machine, comprising the following steps: estimating a first torque using a first method by forming a cross product from an estimated magnetic flux of the electric machine and an actual current of the electric machine, estimating a second torque using a second method by determining a power balance which can be calculated with the aid of a difference between an AC output power of an inverter, which is connected to the electric machine, and a total power loss of the electric machine, and determining the final torque as a weighted average from the first torque, which is weighted with a first weighting, and the second torque, which is weighted with a second weighting. The present disclosure also relates to a control unit for carrying out this method and to an electrical traction drive having such a control unit.Type: GrantFiled: June 2, 2022Date of Patent: April 21, 2026Assignee: Schaeffler Technologies AG & Co. KGInventors: Jochen Reith, Jiufang Peng, Jurgen Eich

Patent number: 7054732Abstract: A method for controlling an automated clutch of a motor vehicle, wherein the frictional engagement of the clutch is characterized by a physical friction value that changes dependent on an operating state of the clutch, has the steps of: a) modeling the physical friction value as a friction value (RW) in a clutch control unit based on at least one parameter of the power train, wherein the friction value (RW) contains a component representing a dependency of the friction value from a clutch temperature, and b) controlling the frictional engagement of the automated clutch based on the friction value (RW) that was obtained as a result of the modeling in step a).Type: GrantFiled: February 2, 2005Date of Patent: May 30, 2006Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Christian Rieger, Jurgen Eich, Robert Fischer, Jurgen Gerhart, Mario Jung, Holger Stork

Publication number: 20040127329Abstract: In a method and apparatus for diagnosing a malfunction in a clutch actuator of a motor vehicle, the actual position of the clutch actuator is measured by a position sensor. Simultaneously, an estimated position of the clutch actuator is calculated by an emulation unit that emulates the function of the clutch actuator. Malfunctions of the clutch-actuator are diagnosed by comparing the actual, measured position to the estimated position.Type: ApplicationFiled: December 12, 2003Publication date: July 1, 2004Inventors: Jurgen Eich, Klaus Kupper, Alexander Schweizer, Ralf Enderlin, Thomas Jager, Martin Vornehm
