Patent number: 7350634Abstract: Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.Type: GrantFiled: June 28, 2005Date of Patent: April 1, 2008Assignee: LuK Lamellen und Kupplungsbau Beteillgungs KGInventors: Markus Baehr, Christian Rieger, Juergen Gerhart, Gerd Jaeggle, Reinhard Berger

Patent number: 7169082Abstract: A method for altering the coupling torque of a coupling in the drive train of a vehicle with an automatic gearbox and/or automatic coupling in a creep drive mode of a vehicle. According to the invention, the coupling torque is altered according to at least one variable, the parameter of the vehicle describing the creep drive mode thereof.Type: GrantFiled: February 2, 2006Date of Patent: January 30, 2007Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: Christian Rieger, Juergen Gerhart, Mario Jung, Martin Vornehm

Patent number: 7062986Abstract: Methods and apparatus are taught for controlling the operation of a power train in a motor vehicle (1), which may include controlling a clutch actuating mechanism (20) so as to open a clutch (3) in a vehicle pull mode. Then, a transmission (4) may be changed from a first gear position to a second gear position via a neutral position by moving a transmission actuator. At or about the same time, the ignition angle of a spark-ignited combustion engine (2) is preferably shifted during the gear change step to cause the combustion engine to generate a negative engine torque. As a result, engine speed is decreased when the transmission is disposed in the neutral position and a desired engine torque can be rapidly realized as soon as the transmission actuator is disposed in the second gear position. Thereafter, the clutch is closed again.Type: GrantFiled: October 9, 2003Date of Patent: June 20, 2006Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Jörg Metzger, Alexander Schweizer, Frank Bast, Christian Rieger, Johannes Moosheimer, Michael Gallion, Florian Strack

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
