A vehicle trailer for a towing vehicle has a first wheel and at least one second wheel. At least one electric auxiliary drive system is coupled to the first wheel and second wheels for exerting a first torque on the first wheel and a second torque on the second wheel(s). The auxiliary drive system is adapted as an electrical auxiliary drive system capable of recuperation with an auxiliary energy storage device. A force measuring device can measure a longitudinal force signal as the longitudinal force exerted by the towing vehicle on the vehicle trailer by means of a connection. A control unit is adapted to adjust the torque to the first and second wheels on the basis of the electric auxiliary drive system and as a function of the longitudinal force, while maintaining a minimum tractive force. The invention also relates to a vehicle train.
