Patent number: 6558291Abstract: A motor vehicle wherein the combustion engine normally transmits torque to the wheels by way of an infinitely variable ratio transmission but receives torque from the wheels when the vehicle is coasting. The operator of the vehicle can manipulate one or more components (e.g., the gas pedal) of an actuating unit which includes one or more sensors arranged to monitor one or more parameters of the vehicle, and the ratio of the transmission is automatically regulated—at least temporarily—when the vehicle is coasting so that the speed of the coasting vehicle does not increase but decreases or remains unchanged. For example, one sensor can monitor the speed of the motor vehicle and another sensor can ascertain whether or not the gas pedal is depressed.Type: GrantFiled: April 13, 2000Date of Patent: May 6, 2003Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventor: Michael Salecker

Publication number: 20020134637Abstract: A method of monitoring a torque transmission system with a manually switchable gearbox in the power train of a motor vehicle involves the utilization of at least one sensor unit at the input side of the torque transmission system to ascertain relevant positions of the shift lever of the gearbox and the driving torque of the engine of the motor vehicle. The thus obtained shift lever signals are memorized, together with comparison signals which are obtained as a result of filtering of the shift lever signals, and various characteristics of such signals are recognized and identified to indicate the intention of the operator of the vehicle regarding the switching of the gearbox. The thus obtained switching intention signals are transmitted to a controlled clutch operating system.Type: ApplicationFiled: April 12, 2002Publication date: September 26, 2002Applicant: LuK Getriebe System GmbHInventors: Michael Salecker, Uwe Wagner, Michael Reuschel, Martin Rauser, Bruno Muller, Alfons Wagner

Patent number: 6422367Abstract: The present invention presents a method for operating a motor vehicle which has at least one clutch device. The method includes determining at least one part of a dependence of a path of at least one clutch characteristic on at least one pressure value. The pressure value relates to a pressure of a hydraulic fluid at a predetermined site. According to one embodiment of the present invention, the hydraulic pressure is detected in an area of a torque sensor which produces the hydraulic pressure dependent on a size (magnitude) of an engine torque.Type: GrantFiled: November 3, 1999Date of Patent: July 23, 2002Assignee: LuK Getriebe-Systeme GmbHInventors: Michael Reuschel, Michael Salecker, Oswald Friedmann, Georg Hommes

Patent number: 6411879Abstract: A motor vehicle (201) has an engine (201), a clutch (203), and a transmission (204) with a shift lever (230). A sensor (232) arranged at the shift lever (230) detects movements of the shift lever or forces applied to the shift lever. When the sensor (232) detects a movement or force, the activity is interpreted as a signal that the driver intends to shift gear. A detector system of the motor vehicle detects conditions such as the presence and magnitude of a mechanical play which can affect the process of shifting gears in the transmission (204).Type: GrantFiled: May 3, 2001Date of Patent: June 25, 2002Assignee: LuK Lamellen und Kupplungsbau GmbHInventors: Klaus Küpper, Michael Salecker

Patent number: 6352146Abstract: A clutch between the combustion engine and the manual multiple-gear-ratio transmission in the power train of a motor vehicle is disengaged or otherwise adjusted in response to a signal from a control unit which processes signals transmitted by sensors serving to monitor the positions and/or the extent of movements of one or more mobile components of the manual transmission. A signal to disengage or to otherwise adjust the clutch is generated when the monitored position(s) of and/or the magnitude(s) of force(s) acting upon one or more mobile components indicate that the operator of the motor vehicle intends to shift the transmission into or from a selected gear ratio.Type: GrantFiled: June 27, 2000Date of Patent: March 5, 2002Assignee: LuK Getriebe-Systeme GmbHInventors: Wolfgang Eismann, Michael Salecker, Gunter Jürgens

Patent number: 6322477Abstract: A method for influencing a shift process connected with a change in transmission ratio when driving a motor vehicle that has a set of driven wheels subject to longitudinal and transverse forces, the method including detecting whether or not the vehicle is traveling around a curve and, if doing so when the shift process is in progress, influencing the shift process so as to decrease the longitudinal forces that act on the driven wheels as a result of the shift process. Also disclosed is an apparatus for performing the disclosed method including a detector for detecting whether or not the vehicle is traveling around a curve and a transmission ratio shifter responsive to the detector that, if the vehicle is traveling around a curve when the shift process is in progress, performs the shift process so as to decrease the longitudinal forces that act on the driven wheels as a result of the shift process.Type: GrantFiled: October 7, 1999Date of Patent: November 27, 2001Assignee: LuK Getriebe GmbHInventors: Jürgen Eich, Michael Salecker, Thomas Jäger

Patent number: 6276504Abstract: A twin clutch has two clutch discs, each arranged on one of two coaxial shafts, having a clutch cage, which surrounds the clutch discs in the manner of an annulus, and having pressure plates which are held in a rotationally fixed manner therein and are arranged axially in such a way that they can be displaced separately axially between the clutch discs and can be pressed against the clutch discs by a diaphragm-spring arrangement arranged axially between them and can be disengaged from the respective clutch disc by means of separate release members. The diaphragm-spring arrangement includes at least two diaphragm springs of essentially the same type arranged in series, giving a broad actuating range with a constant spring force. When the release members are unactuated, the diaphragm-spring arrangement operates in this actuating range irrespective of clutch wear, it being possible to transmit approximately half of a maximum torque to be transmitted at each clutch.Type: GrantFiled: March 20, 2000Date of Patent: August 21, 2001Assignee: DaimlerChrysler AGInventors: Ernst Tscheplak, Michael Salecker, Gunter Worner

Patent number: 6250448Abstract: A motor vehicle is equipped with a device for automatically actuating a clutch in the drive train. A clutch actuator is directed by a control unit which, in turn, is responsive to a control signal from an electronic stability system (ESS). When the control signal indicates that the electronic stability system is in action, the actuator will set the degree of clutch engagement or the amount of torque that the clutch will transmit.Type: GrantFiled: May 8, 2000Date of Patent: June 26, 2001Assignee: LuK Lamellen und Kupplungsbau GmbHInventors: Michael Salecker, Martin Zimmermann

Patent number: 6113515Abstract: The power train of a motor vehicle has an automated clutch and a control unit which causes one or more actuators to change the rate of torque transmission by the clutch from the engine to the transmission of the power train in response to appropriate signals from various sensors. When the transmission is shifted into gear while the engine is idling, while the brake or brakes are not applied and while the gas pedal is not depressed, the setting of the clutch is such that the transmission causes the motor vehicle to carry out a crawling movement as a result of a change of the rate of torque transmission by the clutch from the idling engine to the transmission from a first value (e.g., zero) to a second value as a function of the monitored temperature of the clutch.Type: GrantFiled: April 30, 1998Date of Patent: September 5, 2000Assignee: LuK Getriebe-Systeme GmbHInventors: Michael Salecker, Oliver Amendt, Thomas Jager

Patent number: RE37572Abstract: A motor vehicle has a clutch which is controlled by an electronic clutch management system.
