Method and device for adjusting the friction coefficient of a friction clutch situated in a hybrid power train

Patent Number: 8105205
Publication Date: 2012-01-31
Inventor: Reuschel, Michael

A method for adjusting the friction coefficient of a friction clutch situated in a hybrid power train between an electric machine and a combustion engine, actuated by a clutch actuator, the friction coefficient is adjusted by a torque transmitted by the friction clutch, which is determined when starting the combustion engine by the electric ...

Method and device for controlling a fluid-actuated control system

Patent Number: 8105204
Publication Date: 2012-01-31
Inventors: Ingenbleek, Robert; Steinborn, Mario; Ulbricht, Markus; Brentel, Armin

A method and a device for controlling a fluid-actuated control system of an automatic or automated transmission of a motor vehicle, which has at least one pressure medium source, at least two control elements that are actuated by pressurized fluid and a control device for controlling the fluid-actuated control system. A further control module is used to reduce; the number and power consumption of valves that are actuated simultaneously to control the control elements; and the mechanical ...

Dual clutch transmission

Patent Number: 8105203
Publication Date: 2012-01-31
Inventors: Ishii, Norihiro; Koga, Kazunari; Ebihara, Tomoyuki; Sasahara, Kengo

A dual clutch transmission comprises a first clutch to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches. A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is ...

Transmission control device for motorcycle

Patent Number: 8105202
Publication Date: 2012-01-31
Inventors: Nedachi, Yoshiaki; Kojima, Hiroyuki

To automatically shift the shift position of an automatic transmission depending on whether or not the rider is seated or the side stand is retracted. When the vehicle is at a stop with an engine running, and it is detected that the rider is not sitting on a rider seat, an automatic transmission is automatically shifted to the neutral range while maintaining the operation of the engine. Further, when the vehicle is at a stop with the engine running, and the automatic transmission has been ...

Process for controlling a friction clutch

Patent Number: 8100812
Publication Date: 2012-01-24
Inventors: Man, Laszlo; Dreher, Alexander; Burkhart, Dirk

The invention relates to a process for controlling an automated friction clutch with a wear adjustment device that adjusts extended clutch stroke by a discrete magnitude through the wear of friction lining at maximum transmittable torque of the friction clutch. To guarantee safe self-adjustment, also during a long operation period under the maximum clutch torque, under specified preconditions, for instance, during the start of the internal combustion engine and without gear engagement, the ...

Automatic disengaging/engaging method of a clutch dependent power take-off

Patent Number: 8100811
Publication Date: 2012-01-24
Inventors: Karlsson, Svante; Karlsson, Lars

An automatic disengaging method for a master clutch dependent power take-off (PTO) arranged in a vehicle for preventing undesired movement or actions of the implements associated with the PTO and undesired wear of a clutch collar (release bearing). The PTO is driven by an engine via a master clutch between a crankshaft of the engine and an input shaft in a gearbox. The gear box further comprises an output shaft which is powered by the input shaft, optionally via an intermediate shaft. A ...

Transmission scheduling for multi-stroke engine

Patent Number: 8096920
Publication Date: 2012-01-17
Inventors: Bidner, David Karl; Surnilla, Gopichandra

An approach is described that coordinates transmission shifting with changing between two-stroke and four-stroke combustion to improve shift and drive performance. In one example, responsive to a driver tip-in, the system may transition the engine to a two-stroke combustion mode from the four-stroke mode and increase a transmission gear ratio in order to avoid transmission shifts during the subsequent ...
