Abstract: A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.
