Abstract
A method and device for operating a dual clutch transmission connectable to an internal combustion engine provided in a vehicle includes providing a control unit for managing at least the internal combustion engine and the transmission, providing a prediction model including at least one simulated shift sequence for the transmission, predicting the time between a first power upshift/downshift and a second power upshift/downshift for the transmission by using the at least one prediction model, modifying at least one parameter for operating the transmission if the predicted time between the first power upshift/downshift and the second power upshift/downshift for the transmission is shorter than a predetermined time.
