Abstract
A method for, during creep mode, performing gearshift in a vehicle powertrain comprising a combustion engine, a gearbox, and a clutch is provided. The method comprises, in response to a request for gearshift, disconnecting the combustion engine from the gearbox by opening the clutch. The method further comprises, when the combustion engine is disconnected from the gearbox, shifting the gearbox and controlling the speed of the combustion engine to a target speed. Said target speed constitutes a combustion engine speed corresponding a desired combustion engine torque for completing a torque ramp during closing of the clutch. The method further comprises connecting the combustion engine to the gearbox by closing the clutch. A control device configured to perform the method and a vehicle comprising the control device are also provided.
