ABSTRACT:
Impacts with a vehicle body panel are detected by sensing airflow inboard of the vehicle body panel. The airflow can be measured by heated element sensor, a Pitot tube sensor, a venturi sensor or other airflow-responsive sensor. For side impact detection, the sensor is located in a door or pillar on the side of the vehicle; for frontal impact detection, the sensor may be located behind the front bumper. Multiple sensors mounted in distributed locations can be used to determine the location and extent of an impact.
