Abstract

An activating algorithm is generated for rollover detection for safety-related devices in automotive vehicles. First, a theoretical characteristic rollover curve, adapted to the respective vehicle, is assumed. This theoretical rollover curve is approximated with the aid of low pass filter functions to specific cutoff frequencies and trigger thresholds respectively. These cutoff frequencies and trigger thresholds are adapted to the rollover scenarios to be detected. The sensor signals generated by an angular rate sensor for sensing the rotational velocity of the rolling motion, are processed and evaluated by these low pass filter functions for activating a safety device, if necessary. The low pass filter functions provide a rollover curve which is an approximation of the theoretical rollover curve.
