Patent ID: 8297249

Claim:
A method for controlling a start-up phase of a motor vehicle which is driven by an internal combustion engine, the start of the internal combustion engine occurring by means of at least one electrical machine that can be operated as a motor, and with an automatically actuatable clutch in a drive train between the internal combustion engine and the electrical machine, wherein the internal combustion engine is driven with closed clutch during a starting process by the electrical machine and a clutch capacitance of the clutch is at least reduced or the clutch is opened depending on at least one defined parameter, selected from the group engine speed of the internal combustion engine, motor speed of the electric motor, elapsed starting time and torque of the electrical machine, wherein the reduction of the clutch capacitance is started after an upper dead center position of a piston of the internal combustion engine, wherein the electrical machine is operated in such a way that a torque of the electrical machine varies according to a characteristic of an initial torque to overcome friction of the internal combustion engine and wherein an upper dead center position of the internal combustion engine is derived from a level of a torque of the electrical machine.
