A drive-train of a vehicle with a hybrid drive comprising an internal combustion engine and an electric machine and an automated group transmission connected between the hybrid drive and a drive axle. The transmission comprises a main transmission having a main shaft, countershafts, and a splitter group connected up upstream from the main transmission. The electric machine is connected to the countershafts. The splitter group and the main transmission have a common direct gear which is engaged by a clutch to support traction force shifting of the main transmission. The clutch connects a transmission input shaft to the main transmission shaft to form the direct gear. While the direct gear is engaged, the connections of the transmission input shaft and the main transmission shaft to the countershaft and the electric machine are separated.
