1. A method, performed by a control device, for performing a gearshift in a powertrain of a vehicle during creep mode,
the powertrain comprising:
a combustion engine,
a gearbox, and
a clutch arranged between the combustion engine and the gearbox,
the method comprising:
in response to a request for gearshift, disconnecting the combustion engine from the gearbox by opening the clutch;
when the combustion engine is disconnected from the gearbox, shifting the gearbox and controlling a speed of the combustion engine to a target speed, said target speed constituting a combustion engine speed corresponding to a desired combustion engine torque for completing a torque ramp during closing of the clutch and being equal to or greater than a minimum threshold combustion engine speed; and
connecting the combustion engine to the gearbox by closing the clutch.
