Abstract

A method for operating a drive device is disclosed. The drive device has manual transmission has an intermediate shaft operatively connected with an output shaft, and a countershaft. In a first acceleration operating mode of the drive device a first electric motor and a second electric motor of the drive device are operatively connected with the intermediate shaft via the countershaft, and in a second acceleration operating mode the first electric motor is directly connected with the intermediate shaft and the second electric motor is operatively connected with the intermediate shaft via the countershaft. When switching between the first acceleration operating mode and the second acceleration operating mode the operative connection between the first electric motor and the intermediate shaft is interrupted for a defined switching time period. During the switching time period the second electric motor is operated with an overload torque.
