| description | A drivetrain has at least one electric drive machine configured for driving a motor vehicle, a drivable rear motor vehicle axle for transmitting drive forces of the electric drive machine to a roadway surface, and a vehicle transmission which has at least one transmission ratio stage and which is configured for transmitting drive forces in the direction of the drivable rear motor vehicle axle. The transmission ratio stage can, in at least one operating mode of the drivetrain, be engaged by a transmission control unit. The vehicle transmission can, from the transmission ratio stage, be shifted by the transmission control unit into a neutral position in which a transmission output shaft is freely rotatable relative to a transmission input shaft. For control of the electric drive machine, an electric motor control unit is provided, wherein the electric drive machine is, by way of the electric motor control unit, operable at least in a motor operating mode and in a neutral mode, in which the electric drive machine is rotatable in a manner free from torque. The electric motor control unit and the transmission control unit are connected to one another by at least two control lines configured for transmitting control commands between the control units. A control command can be transmitted by the electric motor control unit via at least one of the two control lines to the transmission control unit, such that the transmission control unit sets the vehicle transmission into the neutral position. |
