A method of controlling shifting in a transmission having a first partial transmission, designed as a dual-clutch transmission, which comprises first and second clutches by which the dual-clutch transmission can be functionally connected to a turbocharged internal combustion engine. A second partial transmission is arranged in the drive-train, downstream of the dual-clutch transmission, which is in the form of a main transmission that shifts with traction force interruption. To at least reduce traction power loss of the turbocharged engine after a traction shift, during a traction shift involving a gearshift in the main transmission, the clutches are at least partially engaged so as to be braced against one another and produce a torque that acts in opposition to the drive engine by virtue of which, during the traction shift, the supercharge pressure of the drive engine is largely maintained, or at least built up shortly after the traction shift.
A method of controlling shifting in a partial dual-clutch transmission, having a first partial transmission designed as a dual-clutch transmission (DKG) with a dual clutch (DK) comprising a first clutch (K1) and a second clutch (K2) by which the dual-clutch transmission (DKG) is functionally connectable to a drive engine (M) designed as turbocharged internal combustion engine, and with a second partial transmission arranged in a drive-train, downstream from the dual-clutch transmission (DKG), and designed as a main transmission (HG) that shifts with traction force interruption, the method comprising the steps of:
A method of controlling shifting in a partial dual-clutch transmission of a utility vehicle, having a dual-clutch transmission (DKG) and a main transmission (HG), the dual-clutch transmission comprising first and second clutches (K1, K2) which functionally couple the dual-clutch transmission (DKG) to a turbocharged internal combustion engine, and the main transmission shifting with an interruption in traction force and being arranged in a drive-train downstream from the dual-clutch transmission, the method comprising the steps of:
