Abstract: A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

Abstract: A method for suppressing noises in a dual clutch transmission, which has two partial transmissions and each partial transmission has at least two synchronizers, for a motor vehicle. A respective shaft of the respective partial transmission is to be synchronized by the respective synchronizer with a respective idler, which is arranged on the respective shaft and is associated with the respective synchronizer, of the respective partial transmission. To suppress noises, one of the synchronizers of one of the partial transmissions is actuated, while the one partial transmission is activated, the other partial transmission is deactivated, and the idler which is associated with the other synchronizer of the one partial transmission is connected in a rotationally-fixed manner to the shaft of the one partial transmission.

Abstract: A method for operating a dual-clutch transmission having a first partial transmission, a second partial transmission, a first clutch assigned to the first partial transmission, and a second clutch assigned to the second partial transmission, in which the dual-clutch transmission is shifted into a parking lock state. The dual-clutch transmission is shifted into the parking lock state by the following steps: while a first gear of one of the partial transmissions is engaged: carrying out an engagement process provided for engaging a second gear of the one partial transmission; determining that the second gear is not engaged despite the engagement process being carried out; selecting a third gear of the dual-clutch transmission different from the first gear and from the second gear; and engaging the selected third gear such that in the park lock condition, the first gear and the third gear are at least temporarily engaged simultaneously.

Abstract: A dual clutch transmission for a motor vehicle, with a first sub-transmission, with a second sub-transmission, with a first clutch associated with the first sub-transmission, and with a second clutch associated with the second sub-transmission. The dual clutch transmission is designed to be shifted into a parking lock state, in which two gears of one of the sub-transmissions are simultaneously engaged, and in the lock state, the two gears of the one first sub-transmission are simultaneously engaged. A first gear wheel of a first of the gears, which is designed as loose wheel and rotatably arranged on a first shaft of the dual clutch transmission, is connected in a torque-proof manner to the first shaft, by a first switching element.

Abstract: A method for operating a vehicle having a transmission and a braking device during a journey, during which the vehicle, the transmission of which comprises at least one form-fitting shifting element, moves along a roadway, wherein during the journey of the motor vehicle, its shifting element is movable into formfitting interaction with at least one further component, an anti-lock braking operation is carried out by the braking device, in which at least one braking torque to be applied by the braking device to at least one wheel of the vehicle for braking the wheel is limited at least temporarily to a specifiable value by a regulating device of the vehicle in order to thereby at least temporarily prevent the wheel from locking relative to the roadway.

Abstract: A method for operating a multi-clutch transmission for a motor vehicle, having at least the following steps: a) closing a first clutch of the multi-clutch transmission, in order to transfer an input torque (M_k1) between a drive machine of the motor vehicle and at least one first sub-transmission of the multi-clutch transmission; b) applying a drag torque (M_k2) to a second sub-transmission of the multi-clutch transmission, which is coupled to the first sub-transmission, via a second clutch of the multi-clutch transmission; c) detecting a clutch slip of the second clutch, which is dependent on the drag torque (M_k2); and d) determining a current gear selection of the multi-clutch transmission by evaluating the clutch slip. The disclosure further relates to a multi-clutch transmission and to a motor vehicle having a multi-clutch transmission.
