Claim 9:
10. A method for performing rotational speed synchronisation of a first transmission component having a first initial rotational speed with a second transmission component having a second initial rotational speed, so that they rotate with the same final rotational speed during a gear switch from an initial driving gear to a final driving gear in a stepped gear transmission for a hybrid electric or electric drive train having an electric traction motor, the method comprising:
determining whether the currently available power in an electric storage system of the hybrid electric or electric drive train is above a threshold value of 15 kW and
performing the synchronisation by means of only the electrical traction motor if the currently available power in an electric storage system of the hybrid electric or electric drive train is above a threshold value of 15 kW.
