Abstract: Disclosed is an electric vehicle transmission (6?) comprising a drive input shaft (11), a drive output shaft (13), a first planetary gearset (15), and a second planetary gearset (16). The drive input shaft (11) is provided for connection to an electric machine (7), where each of the first planetary gearset (15) and the second planetary gearset (16) includes a first element (17, 18), a second element (19, 20) and a third element (21, 22), respectively. A first shifting element (A) and a second shifting element (B?) are provided, by the selective actuation of which the drive input shaft (11) can be connected to the drive output shaft (13) by means of the planetary gearsets (15, 16) by engaging a gear. Also disclosed is a drive module (2?) with such an electric vehicle transmission (6?) and a method for operating an electric vehicle transmission (6?).

Abstract: A method for compensation of a support torque at a combustion engine and transmission which provide an overlay of combustion engine and electric machine. The combustion engine, the electric machine, and a transmission gearset are connected with each other via a planetary gearset, which is positioned in front of a downstream transmission gearset. The invention concerns a transmission gearset of a three-shaft transmission, each with a transmission input shaft for the electric machine, and for the combustion engine, and an output shaft. For the connection or disconnection of the transmission input shaft of the electric machine while driving, the electric machine is used for the synchronization of the input shaft of the electric machine, and the created support torque at the combustion engine is determined, based on this support torque, to match a combustion engine torque and thus to compensate the support torque.

Abstract: A method of controlling a dual-clutch transmission having two partial transmissions that can be connected to a drive engine such that a target gear, in a respective load-free partial transmission to be engaged following the currently active gear, can be preselected. To reduce the energy consumption caused by transmission losses, the method includes the steps of: determining a possible target gear, determining overall transmission losses for both when a target gear is preselected, and when a target gear is not preselected, determining whether the overall transmission loss is greater when a target gear is preselected or when no gear is preselected, deciding whether a target gear should or should not be preselected using the overall transmission loss determined as a criterion, and implementing measures that correspond to the decision reached.

Abstract: A device and a method for rapid disengagement of a clutch (2). The device has a mechanical transmission path (26) which is arranged between a clutch actuator (12) and a first clutch part and comprises a knee lever (4) which facilitates rapid disengagement of the clutch (2).
