A vehicle upfront sensor is described that has a cavity and a sensing element therein. A collision is detected as a function of the deformation of the cavity. The sensing element may be designed as a pressure or temperature sensor, the cavity then being largely closed, so that an adiabatic pressure or temperature increase is measurable.

Vehicle upfront sensor

A method of data transmission from a sensor to a control unit and a sensor and control unit are described, the sensor transmitting both differential values and absolute values. The differential values are analyzed in the control unit to perform the function provided, and the absolute values are analyzed for the plausibility check of the function.

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.
