The disclosure relates to a method for assisting a towing vehicle in the event of a loss of traction via a trailer vehicle. The method includes determining a differential slip between a driven wheel and a driveless wheel of the towing vehicle via a brake control unit and generating an acceleration demand dependent on the determined differential slip. The method further includes transmitting the acceleration demand to a trailer brake control unit, generating an activation signal for an electric drive of the trailer vehicle in dependence upon the acceleration demand in the trailer brake control unit, transmitting an activation signal to the electric drive of the trailer vehicle and generating a drive torque via the electric drive in dependence upon the activation signal. The disclosure furthermore relates to a towing vehicle, a trailer vehicle, and a combination thereof for carrying out the method.
