  • Method of gear shifting a dual clutch transmission
    Patent number: 8701517
    Abstract: A method for gear shifting a dual clutch transmission from an initial gear into a target gear and a respective dual clutch transmission are described. The dual clutch transmission comprises a first partial transmission and a second partial transmission. When shifting from an initial gear into a target gear which are both allocated to the first partial transmission, gears are shifted at least for a short time period into the support gear prior to gear shifting from the support gear into the target gear. A process of an uninterrupted reduction of the transmitted clutch torque down to zero at a first clutch allocated to the initial gear is started prior to starting a process of closing the second clutch allocated to the support gear.
