Patent number: 7890238Abstract: A method for diagnosing damage in the shift control actuator of an automated manual transmission, involving at least one of the following steps: (a) determining a shift control actuator is damaged if an actual period needed for synchronizing a gear differs from a nominal time period for synchronizing the gear; (b) moving a shift-control actuator to a limit stop after selection of a gear, and determining a shift-control actuator is damaged if the limit stop that has been reached is an internal limit stop of the shift-control actuator and not a gear transmission limit stop; (c) determining the shift-control actuator is damaged if an actual speed during the overlap phase is not within a speed range within which the engine speed is expected to lie during the overlap phase.Type: GrantFiled: October 22, 2005Date of Patent: February 15, 2011Assignee: Schaeffler Technologies GmbH & Co.

Patent number: 7670256Abstract: The invention relates to a method for reducing chatter in automotive drive train which comprises an internal combustion engine as the drive and a clutch device. According to the method, a rotating component of the drive train is driven by means of the internal combustion engine and the speed of the component is detected. Any chatter is also detected. When chatter occurs, an electric motor is used to transmit a torque onto the rotating component in order to actively dampen the chatter. The rotating component is driven by the electric motor for any chatter component at which the speed of the rotating component decreases and the rotating component is slowed down by the electric motor for any chatter component at which the speed of the rotating component increases.Type: GrantFiled: June 24, 2008Date of Patent: March 2, 2010Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Stefan Winkelmann, Boris Serebrennikov

Patent number: 6997075Abstract: In a motor vehicle transmission, gears representing different transmission ratios are engaged by applying a force to an actuator output element that couples a selected gear to a rotary shaft. A synchronizing device blocks the coupling of the gear to the shaft until at least an approximate synchronization of rpm-rates has been achieved. A synchronization threshold position corresponding to the blocked condition of the actuator element is stored in a memory of a controller device. The controller device periodically performs an automatic adaptation of the stored value for the synchronization threshold position.Type: GrantFiled: April 17, 2003Date of Patent: February 14, 2006Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: Boris Serebrennikov, Klaus Henneberger, Martin Eckert, Frank Bast, Reinhard Berger, Martin Vornehm, Stefan Winkelmann

Patent number: 6510931Abstract: A torque transfer system, particularly an automated shift transmission of a motor vehicle, has a movable shifter element that is subject to a position-dependent force. The gear positions of the transmission correspond to minima of potential energy of the position-dependent force, so that the movable element will have a tendency to fall into the nearest one of the shift positions. To perform a gear shift, the movable shifter element is moved into the vicinity of the targeted gear position by means of a control device directing a shift actuator. When the movable shifter element has stopped moving within a given tolerance band of the targeted position, the control device generates a stall-releasing signal, e.g., a series of pulses of alternating polarity to overcome a holding force or holding torque of the movable element, so that the latter will seek a position of minimum potential energy and thus move towards the targeted gear-shift position.Type: GrantFiled: December 7, 2001Date of Patent: January 28, 2003Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Reinhard Berger, Martin Vornehm, Stefan Winkelmann
