Controlling an actual slip of at least one driven axle of a motor vehicle with at least one axle having at least one wheel and a one drive unit for providing a drive torque for the axle and for the wheel can be carried out by a control device for controlling the drive unit. The control device can be configured for establishing a first actual speed of the motor vehicle; establishing a second actual speed of the at least one wheel; calculating a target speed of the at least one wheel for the established first actual speed taking into account parameters; determining an actual slip of the at least one wheel with respect to a substrate on which the motor vehicle is being moved; when the actual slip exceeds a defined first limit slip, generating a limit torque by which the drive torque produced by the drive unit is adjusted.

Automatically controlling a driven axle of a motor vehicle

A method for operating an electrical machine is used to calculate a value of a first torque which can be provided at a maximum by the electrical machine in a future interval, wherein, by limiting the torque which is provided in the interval to the value, overheating of at least one semiconductor, which is required for transmitting the electrical power, due to a power loss is prevented and/or the threat of overheating and the onset of derating is diagnosed and therefore prevented.

Operating an electrical machine

A method controls a drive system for an axle of a motor vehicle, wherein the drive system has at least an electrical machine as drive unit, a drive shaft which is driven by the drive unit, a first output shaft and a second output shaft and also a first clutch which connects the drive shaft to the first output shaft and a second clutch which connects the drive shaft to the second output shaft.

Controlling a drive system for at least one axle of a motor vehicle

A drive system for at least one axle of a motor vehicle can be controlled, wherein the drive system has at least one electrical machine as drive unit, a drive shaft which is driven by the drive unit, a first output shaft and optionally a second output shaft and also a first clutch which connects the drive shaft to the first output shaft and optionally a second clutch which connects the drive shaft to the second output shaft, and furthermore a control unit for controlling the drive unit and the clutches, wherein the first output shaft and the optional second output shaft are arranged on a common axle.
