ABSTRACT:
The invention constitutes a supplement to patent application No. P 31 34 883 and to patent application No. P 32 08 088. It relates to the electronic switching-off of the correction circuitry in the event of a large dwell angle and simultaneously maximum correction value. This object is attained by comparing the speed-dependent output voltage of an induction sensor at a comparator to a reference voltage which is chosen so as to be exceeded by the output voltage of the induction sensor from a certain rotor speed on with an output pulse being released at the comparator. The capacitor at which the sawtooth-shaped signal is generated is discharged by means of this output pulse such that there will not be any further correction of the control signal.
