用于记录车辆相关数据的方法、传感器装置和车辆
摘要：
在用于记录车辆相关数据、特别是检测和评估车辆轻微损伤的方法中，其中应该检测和分析通过事件、例如通过损伤和/或接触造成的固体声，也检测小的轻微损伤。这通过以其总频谱记录固体声来实现，频谱利用滤波器被划分为下频率范围和上频率范围，事件通过上频率范围中的至少一个振幅来表征，其中，具有上频率范围中的振幅的事件被包含到包络线分析中，在对下频率范围进行包络线分析时测定下功率密度和在对上频率范围进行包络线分析时测定上功率密度，从上功率密度与下功率密度的比例中确定相对测量值并借助相对测量值进行事件的评估并将事件存储。
摘要（英）：

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.
