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.
