A method for an internal combustion engine as well as operating according to the ignition device

摘要

The present invention relates to the recognition of the switching state of a stop switch (17) on a switch terminal (16) of an ignition device (1) for an internal combustion engine, in which a trigger pulse (s_Z) for driving an electronic ignition switch (14) and via an ignition coil (6) is a (first) energy storage means (10) unloading, as well as in the course of this discharge a negative and positive voltage (s_(±)) a voltage signal (s₁) is generated, which for the synchronization of a the state of the stop switch (17), in particular its closed position, query representing a voltage value (u₂₁(t_a)) at the switch terminal (16) is used.
