A method for operating a motor vehicle () having at least one driven axle () with a locking differential (), where when the motor vehicle () is driving and the locking differential () concerned is engaged on at least one driven axle (), it is checked whether the motor vehicle is driving round a curve. If it is found that the motor vehicle is driving round a curve, the engaged locking differential () is actuated to disengage it and it is checked whether the locking differential () concerned has in fact been disengaged. If it is found that the locking differential () concerned has not been disengaged, the wheel of the driven axle () concerned on the outside of the curve is braked.

Method and control device for operating a motor vehicle

Disclosed is an electric vehicle transmission (&#x2033;) comprising a drive input shaft (), a drive output shaft (), a first planetary gearset (), and a second planetary gearset (). The drive input shaft () is provided for connection to an electric machine (), where each of the first planetary gearset () and the second planetary gearset () includes a first element (), a second element () and a third element (), respectively. A first shifting element (A) and a second shifting element (B') are provided, by the selective actuation of which the drive input shaft () can be connected to the drive output shaft () by means of the planetary gearsets () by engaging a gear. Also disclosed is a drive module (&#x2033;) with such an electric vehicle transmission (&#x2033;) and a method for operating an electric vehicle transmission (&#x2033;).

Electric vehicle transmission

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.
