Zusammenfassung:	The invention relates to a method for determining at least one motor torque specification in a motor vehicle having two axles, two wheels per axle and one or more drive motors. According to the method, a wheel torque specification based on the respective wheel is determined for each wheel in dependence on an accelerator signal characteristic of the position of the accelerator pedal or a signal of a system influencing the longitudinal movement of the vehicle. Alternatively, an axle torque specification for each axle based on the respective axle can also be determined. An approach in which a wheel torque specification based on the respective wheel is determined for each wheel of a first axle can also be used, wherein an axle torque specification based on the second axle is additionally determined. According to the method, a motor torque specification for the respective drive motor is calculated for each of the one or more drive motors in dependence on one or more wheel torque specifications and/or axle torque specifications.
