<p>A method for preparing a start-up of an internal combustion engine with a belt-driven starter generator having a stator and rotor windings, the starter generator being operated so that its generated torque slowly increases over a period of more than two rotor winding-time constants. The stator winding is energized so that the generated torque slowly increases over a period of more than two rotor winding-time constants. The rotor winding is energized and, when a field current through the rotor winding is below a lower threshold value prior to the beginning of its energization, the stator winding is energized, before the field current is above an upper threshold value. The belt of the starter generator is pre-tensioned prior to the actual starting operation by activating the electric machine so that jolts, vibrations and noises, which occur during the start-up of the internal combustion engine with a starter generator, may be avoided.</p> |
