Abstract
The invention is directed to a method for turning off the starter of an internal combustion engine, wherein a starter motor which can be engaged with the internal combustion engine for cranking is disengaged and switched off when the internal combustion engine runs by itself, and the time at which the starter is switched off is determined from a curve of a starter current of the starter motor. It is provided that a signal proportional to the starter current (IS) is evaluated for determining the time (tA) for switching off the starter, wherein there is an evaluation of a characteristic line with a signal which is proportional to the starter current, which characteristic line is dependent on an operating state of the internal combustion engine.
