Abstract

A drive system has a main electric drive and an auxiliary electric drive. A frequency converter controls a torque of the auxiliary drive. A planetary gear has a ring gear, a sun gear, a planet gear and a planet gear carrier. The ring gear is coupled to the main drive, the sun gear is coupled to an output shaft and the planet gear carrier is coupled to the auxiliary drive. A clutch path is disposed between the planet gear carrier and the input shaft. A controller operates the drive system in a first range with the clutch closed and the switching apparatus open, or in a second range with the clutch open and the switching apparatus closed. The controller is adapted to superelevate the torque of the auxiliary drive during a transition between the first and second ranges beyond the torque that the auxiliary drive is able to provide permanently.
