Abstract
A method for detecting scratches and bumps applied to a vehicle uses an acceleration sensor. Signals of the sensor are analyzed and evaluated based on duration and frequency.
Claims13
A method for detecting the application of scratches and/or bumps to a vehicle using at least one acceleration sensor mounted to the vehicle, wherein signals which are output by the acceleration sensor are monitored and analyzed by an electronic device, the method comprising:
- analyzing the envelope of the signals,
- determining if a signal is to be evaluated based on the envelope analysis;
- and
- if the signal is to be evaluated,
- evaluating the signal on the basis of a duration and a frequency of the signal, wherein
- the signals are evaluated in a plurality of frequency bands which are respectively filtered out from the total bandwidth of the signal.
