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 amplitude and frequency. Relationships between the amplitudes and frequencies provide a basis to classify a vehicle contact event as a bump or a scratch.
Claims18
A method of classifying a vehicle contact event as at least one of a bump or scratch, the method comprising:
- detecting the vehicle contact event based on a signal from an acceleration sensor associated with the vehicle;
- determining an amplitude of the signal at each of a plurality of frequencies, wherein each amplitude is either a higher amplitude or a lower amplitude and each frequency is either a higher frequency or a lower frequency;
- determining a relationship between the higher amplitudes and each of the higher frequencies and the lower frequencies;
- determining a relationship between the lower amplitudes and each of the higher frequencies and the lower frequencies;
- and
- classifying the vehicle contact event based on the determined relationships.
