Abstract
An active differential for the controlled distribution of a drive torque generated by a drive motor to two output shafts includes a planetary gear train configured to couple the two drive shafts to a drive shaft of the drive motor, and a distributor motor including a distributor shaft. The distributor motor produces a torque, with a distribution of a drive torque to the two output shafts being dependent on the torque produced by the distributor motor. The distributor shaft and the planetary gear train are coupled by a coupling device which is configured to separate the distributor shaft from the planetary gear train when an operating parameter of the active differential exceeds a predetermined limit value. The operating parameter can hereby be an output torque difference between torques transmitted from the output shafts to the planetary gear train or a time derivative of the output torque difference.
