20140041483 | DRIVE UNIT FOR A HYBRID VEHICLE - A drive unit for a motor vehicle with hybrid drive. The drive unit includes an input shaft which may be connected to the crankshaft of an internal combustion engine of the motor vehicle, a gearbox shaft which may be connected via a toothed hub of a clutch plate as an input shaft of the downstream gearbox, and an electric machine, the rotor of which is connected rotationally fixedly to the clutches. The components are accommodated in a housing having a radially extending housing wall as a bearing wall which forms a physical separation of a chamber of the electric machine and a chamber of the clutches. | 02-13-2014 |
20130025998 | CLUTCH DEVICE AND CONTROL METHOD - A clutch device has a first clutch part and a second clutch part which can selectively be brought into engagement with one another with form fitting as well as a control unit which includes a disengagement unit and an actuator unit operable by means of a fluid pressure. A force disengaging the clutch parts can be generated by the disengagement unit and a force engaging the clutch parts can be generated by the actuator unit. The control device includes a pressure holding device to reduce a fluid pressure acting on the actuator unit in accordance with a predefined characteristic. | 01-31-2013 |
20120221221 | CONTROL METHOD FOR A COUPLING IN THE POWERTRAIN OF A MOTOR VEHICLE - A method of controlling at least one coupling in a powertrain of a motor vehicle includes the steps of: determining at least one slip value which represents an instantaneous slip between different axles of the motor vehicle or between different wheels of an axle; forming an absolute value of the slip value which corresponds to the amount of the slip value; summing the absolute value or a substitute value derived therefrom to a last-formed slip sum value to form an instantaneous slip sum value; comparing the instantaneous slip sum value with a slip sum threshold value: and generating a control signal for actuating the coupling if the instantaneous slip sum value reaches or exceeds the slip sum threshold value. | 08-30-2012 |
