  • Method and system for monitoring integrity of pedestrian protection system in a vehicle
    Patent number: 11361597
    Abstract: A method and system of diagnosing the integrity of a sealed air tube of a pedestrian protection system of a vehicle is provided. The method provides the sealed air tube having a pressure sensor connected at each end of the air tube. The air tube is constructed and arranged to be located in front fascia of a vehicle. A processor circuit is electrically connected with the pressure sensors and the processor circuit has a Fast Fourier Transform element. Natural frequencies of a frequency spectrum of the air tube are obtained when no leak is known to be present in in the air tube. Signals from the pressure sensors are transformed into the frequency domain with the Fast Fourier Transform element. A leak is determined to be present in the air tube if frequencies other than the natural frequencies exist in the frequency spectrum of the air tube.
