A first group of forward gears is allocated to the first partial transmission, a second group of forward gears is allocated to the second partial transmission, each one of the forward gears comprises a particular transmission ratio, two adjacent forward gears comprise adjacent transmission ratios with no transmission ratio of any other forward gear in between, and at least two adjacent forward gears are allocated to the second partial transmission. Further, such a control method for controlling the dual clutch transmission is provided that a torque transmitting gap is closed when gear shifting between the aforementioned two adjacent gears.
