Abstract
A device for side impact detection in a motor vehicle, and a plausibility sensor side impact detection. This plausibility sensor is located in a loudspeaker which is already present in the lateral part for playback of music. This loudspeaker is used as a low-frequency microphone, a circuit being provided for the loudspeaker to differentiate between sound and rapid fluctuations in air pressure. This circuit has a bridge circuit, the differential voltage across the bridge then being used as a plausibility signal. The circuit itself is preferably located in the door.
