Abstract:
A method for monitoring a meshing process of a meshing pinion of a starter motor for a vehicle drive, in which an armature of the starter motor is moved by a magnet, has the following steps: detecting a solenoid signal when a solenoid of the magnet is energized in order to obtain a signal profile, in particular a current profile; generating a differential profile by differentiating the signal profile; determining zero crossings in the differential profile; and monitoring the meshing process on the basis of the determined zero crossings.
