  • Patent number: 10876625
    Abstract: A method for operating a transmission for a motor vehicle having an input shaft, a first shaft connectable to the input shaft via a first input clutch and a second shaft connectable to the input shaft via a second input clutch, a plurality of gearshift clutches, and an output shaft. Different gear ratios between the input and output shafts are implementable by selective engagement of the plurality of clutches. A first torque transmission path between the first and second shafts is engageable with a first friction-locking clutch and a second torque transmission path between the first and second shafts is engageable with a second friction-locking clutch. The method includes actuating, at least intermittently during a synchronization phase in an upshift process of the transmission, the first friction-locking clutch to transmit a first torque and the second friction-locking clutch to transmit a second torque.

    Abstract: A method for operating a transmission for a motor vehicle having an input shaft, a first shaft connectable to the input shaft via a first input clutch and a second shaft connectable to the input shaft via a second input clutch, a plurality of separating clutches, and an output shaft. Different gear ratios between the input and output shafts are implementable by selective engagement of the plurality of clutches. A first torque transmission path between the first and second shafts is engageable with a first friction-locking clutch and a second torque transmission path between the first and second shafts is engageable with a second friction-locking clutch.
