An ignition system and a method for controlling an ignition system for a spark-ignited internal combustion engine are described, having a primary voltage generator for generating an ignition spark and a boost converter for maintaining an ignition spark. The method includes sending a signal from an engine control unit to the ignition system, in order to determine a predetermined ignition timing for triggering an ignition spark, sending an additional signal from the engine control unit to the ignition system, in order to determine a predetermined additional ignition timing for triggering an additional ignition spark, and sending a control signal for influencing the operating mode of the boost converter from the engine control unit to the ignition system between the signal and the additional signal.

Both a method and a use by this method of an apparatus for detecting blocking of a direct current motor (), in particular a direct current motor () for a blower of a motor vehicle, is presented. The direct current motor () is deactivated by a computer unit () with the aid of a switching means () for a defined time period (T). Within the defined time period (T), at least one subsequent time (t, t), an induced voltage (U) of the direct current motor () is measured and forwarded to the computer unit (). The direct current motor () remains deactivated if the induced voltage (U) undershoots a predetermined threshold value (U), or the direct current motor () is reactivated if the induced voltage (U) of the direct current motor () does not undershoot the predetermined threshold value (U).
