Abstract
A method for monitoring an engagement process of an engaging pinion of a starter motor for a vehicle drive, in which an armature of the starter motor is moved, includes detecting a magnetic coil signal while current is applied to the magnetic coil of the magnet, in order to obtain a signal profile, particularly a current profile; generating a frequency profile by transforming the signal profile using a time-frequency transform; comparing the frequency profile to at least one reference frequency profile; and monitoring the engagement process based on the comparison.
