1. A method for controlling slip of a utility vehicle, the method comprising:
receiving an acceleration request signal from a data port of a control unit, the acceleration request signal comprising a request for an acceleration change of at least one driven axle of the utility vehicle;
generating drive control signals that drive an electric drive of the at least one driven axle based on the acceleration request signal using a controller of the control unit:
generating brake control signals that control a friction brake system of the at least one driven axle based on the acceleration request signal using the controller of the control unit;
outputting the generated drive control signals to at least one power amplifier of an inverter of the control unit;
providing energy from an energy store that supplies at least one electric motor of the electric drive based on the drive control signals using the at least one power amplifier;
generating a slip signal using the control unit, the slip signal indicating a slip value of one or more wheels of at least one drive axle which is above a predefined threshold value: and
generating the drive control signals and the braking control signals based on the acceleration request signal and the slip signal.
