Abstract:
A method of controlling shifts in a vehicle transmission, for example a utility vehicle, having a transmission or partial transmission designed as a dual-clutch transmission that shifts as a without traction force interruption. The transmission comprises a dual clutch having a first clutch and a second clutch that are functionally connected to a drive engine, and a transmission or partial transmission comprises a main transmission that shifts with traction force interruption and is connected to a drive-train downstream from the dual-clutch transmission. During shifts in the main transmission that is connected downstream from the dual-clutch transmission, the dual clutch is operated, by pre-loading the two clutches, as a transmission brake and/or an engine brake for adapting the speed of components to be shifted so as to enable short shifting times and ensure comfortable and reliable driving operation.
