Control device, vehicle, computer program, computer readable medium and method for performing a gearshift during creep mode

A computer program product comprising computer program code stored on a non-transitory computer-readable medium, said computer program code configured 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, said computer program code comprising computer instructions to cause at least one control device to perform the following operations:
• 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.

A control device configured to perform 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,
• wherein the control device is configured to perform the operations of:
• in response to a request for gearshift, disconnect the combustion engine from the gearbox by opening the clutch;
• when the combustion engine is disconnected from the gearbox, shift the gearbox and control 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
• connect the combustion engine to the gearbox by closing the clutch.
