Patent number: 9726231Abstract: A hybrid drivetrain having an internal combustion engine which is designed for a maximum internal combustion engine rotational speed; a dual-clutch arrangement which has a first friction clutch and a second friction clutch with a common input element and in each case one output element; a transmission arrangement which has a first sub-transmission and a second sub-transmission; an electric machine connected to the output element of the second friction clutch via a machine transmission ratio (iM), in such a way that a purely electric driving mode can be established via the second sub-transmission. The electric machine is designed for a maximum machine rotational speed. The maximum machine rotational speed divided by the machine transmission ratio is greater than the maximum internal combustion engine rotational speed. The output element of the second friction clutch is structurally designed for the maximum machine rotational speed divided by the machine transmission ratio (iM).Type: GrantFiled: October 11, 2013Date of Patent: August 8, 2017Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann HagenInventors: Uli Christian Blessing, Thomas Hoffmeister, Hansi Gremplini

Patent number: 9120481Abstract: Method for controlling a hybrid drivetrain which has a drive engine and a dual-clutch gearbox which, to establish two power transmission paths, has a first and a second friction clutch and a first and a second component gearbox. An electric machine is connected to the second power transmission path downstream of the second friction clutch in the power flow direction. Purely electric driving operation can be realized by means of the second component gearbox assigned to the second friction clutch. In the event of a gear change in the second component gearbox during purely electric driving operation, a fill-in torque is provided. The fill-in torque is provided from inertial energy of the previously cranked, non-fired drive engine, wherein the drivetrain also has an electric starter motor, and wherein the starter motor is used to crank the drive engine.Type: GrantFiled: September 11, 2013Date of Patent: September 1, 2015Assignee: GETRAG Getriebe-und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Uli Christian Blessing, Thomas Hoffmeister, Ingo Matusche, Thorsten Stepper, Philipp Knopfle

Patent number: 8984989Abstract: Clutch arrangement for a motor vehicle drive train. The clutch arrangement has a first and a second clutch which are embodied as normally open clutches. The first clutch can be activated from an open position into a closed position by means of a first actuator arrangement. The second clutch can be activated from an open position into a closed position by means of a second actuator arrangement. The clutch arrangement has a locking device for locking a clutch in the closed position. Only the second clutch can be locked in the closed position by means of the locking device, while the first clutch cannot be locked in the closed position. Thus, the first actuator arrangement has to be supplied with energy in order to secure the first clutch in the closed position.Type: GrantFiled: September 5, 2012Date of Patent: March 24, 2015Assignee: GETRAG Getriebe-und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Uli Christian Blessing, Guenter Ruehle, Martin Seufert

Patent number: 8577573Abstract: A method for setting the engagement point of a friction clutch of a multi-step transmission for a motor vehicle. The friction clutch can be activated, controlled, by means of a clutch actuator. A set point value of the clutch actuator is set for the engagement point of the friction clutch as a function of a time profile of a physical variable which occurs starting from a transition state after activation of the friction clutch to a transition value.
