  • Device and method for side-impact identification
    Patent number: 6725961
    Abstract: A device and a method, respectively, are proposed to detect side collisions, in which a temperature sensor is located in a motor-vehicle side section. In case of a side collision, the temperature sensor measures the short-term adiabatic temperature increase and a control device detects a side collision as a function of the measured temperature increase and the temperature gradient. A triggering decision is made by plausibility testing using an acceleration sensor.

  • System for triggering restraining means
    Publication number: 20040059487
    Abstract: A system for triggering restraining means which has at least one impact sensor and at least one pedestrian-impact sensor, signals being transmitted from these sensors to a processor which is configured such that the processor triggers the restraining means as a function of a linkage of the signals.

  • Device for sensing lateral impact
    Publication number: 20040032322
    Abstract: A system for side-impact detection is proposed which is distinguished in that both a temperature sensor as well as an acceleration sensor are accommodated in a structural unit. One of the sensors in each case is used for a plausibility check.

  • Device for side impact detection in a motor vehicle
    Publication number: 20030140679
    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.
