Abstract
A method for recording vehicle-relevant data, in particular for detecting and evaluating damage to a vehicle in which structure-borne noise caused by an event, such as damage or contact, is detected and evaluated. The noise is recorded with its entire frequency spectrum, the frequency spectrum is divided into a lower frequency range and an upper frequency range, and an event is characterized by at least one amplitude in the upper frequency range. The event having an amplitude in the upper frequency range is included in an envelope curve analysis, in which a lower power density and upper power density are determined for a lower and upper frequency range, respectively. A relative measured value is determined from the ratio of the upper power density to the lower power density, an evaluation of the event is made by means of the relative measured value, and the event is stored.
