A method for operating a drive system of a motor vehicle, the drive system comprising: a drive unit (1); a group transmission (2) with sub-transmissions; and a disengagement clutch (5) connected between the drive unit and the group transmission, wherein if the speed becomes less than a threshold value, the disengagement clutch (5) is disengaged and one of the sub-transmissions is shifted to neutral for transmission pre-selection, and the other sub-transmissions or each of the other sub-transmissions is shifted to a force-locked state, wherein the disengagement clutch (5) is then at least partially closed and the drive unit (1) is brought to a defined speed, wherein a starting shift is then checked when the group transmission (2) requires force-locked engagement. If the driver expects to shift gears, then if the driver expects to shift gears, then it is checked whether the target speed of the drive unit (1) is greater than or less than the current input speed of the group transmission. If there is a starting shift and if the target speed of the drive unit (1) is less than the current input speed of the group transmission when the driver expects to shift gears, then the disengagement clutch (5) is disengaged and the sub-transmission in neutral is synchronized by the transmission brake (4). If the target speed of the drive unit (1) is greater than the current input speed of the group transmission (2) when the driver expects to shift gears, then the sub-transmission in neutral is synchronized by the drive unit (1).
