open first clutch k 1 also in the lower transmission ratio when the shifting element i is activated and in the upper transmission ratio when the shifting element j is activated without power transmission and can therefore be shifted while free from load the dual clutch transmission described above enables at least eleven powershiftable forward gears v 1 v 2 v 3 v 4 v 5 v 6 v 7 v 8 v 9 v 10 v 11 and six partly powershiftable reversing gears r 1 r 2 r 3 r 4 r 5 r 6 the attached fig2 shows an example of a shifting scheme for this in the table of fig2 the shifting elements activated in each case are marked by as dot according to the table the shifts take place in alternation by way of the two clutches k 1 k 2 beginning with the first clutch k 1 in the first seven gears the lower transmission ratio of the range group gp is activated as made clear by the dots in column i as necessary the two countershafts w_v 1 w_v 2 are coupled to one another which is done by engaging the shifting element e gearshifts within the main group hg take place without traction force interruption in a known manner by preselecting the respective next gear and then with a time overlap opening the clutch k 1 or k 2 of the active gear and closing the clutch k 2 or k 1 respectively of the new gear the seventh forward gear is.
