Abstract
A method and an apparatus for collision detection are proposed, which serve to make faster plausibility checking of a collision signal possible. To that end, the unfiltered sensor signal is used, and this unfiltered sensor signal is compared with a plausibility threshold. Preferably as a function of the comparison of the unfiltered signal with the plausibility threshold, a plausibility flag is set. This plausibility flag can be maintained for a relatively long time by a hold element. As the sensor, an acceleration sensor can advantageously be used.
