Claim:
1. A procedure for controlling a torque transmission rate of a clutch by a clutch control unit, wherein the clutch is in connection with a transmission and an electric machine and wherein a coupling half of the clutch is configured to receive torque from the electric machine to transfer torque between a combustion engine and the transmission, the procedure comprising: determining whether the clutch is in a slipping condition or a friction point; and when the clutch is in the slipping condition or the friction point, increasing, by the clutch control unit, the torque transmission rate of the clutch after detecting a shift demand for a shifting process to shift from a neutral position of the transmission to a target gear of a plurality of transmission gears, wherein increasing the torque transmission rate after detecting the shifting demand results in a reduction of a retroactive effect on the slipping condition or the friction point during the shifting process.
