METHOD FOR DETERMINING A CRITERION OF THE SEVERITY OF AN ACCIDENT BY MEANS OF AN ACCELERATION SIGNAL AND A SOLID-BORNE SOUND SIGNAL

摘要

A method for determining a criterion of the severity of an accident by means of an acceleration signal and a solid-borne sound signal is presented, wherein the signal edge direction of the absolute value of the acceleration signal is detected. If the signal edge of the absolute value of the acceleration signal drops, the solid-borne sound signal which occurs in the process is evaluated, in particular integrated and the criterion of the severity of the accident is derived therefrom. This criterion of the severity of the accident can be used directly, or as a function of criteria, to trigger the protection devices.
