Abstract
In a method for controlling a safety system in a vehicle, wherein an output signal of at least one impact sensor is subjected to frequency analysis in an evaluation unit which is integrated into an electronic control unit, the frequency analysis is performed in at least one predetermined frequency range, the spectrum of the output signal is compared with references patterns, the dependence of the spectrum on the present speed of the vehicle and/or the present outside temperature of the vehicle is taken into account, and a triggering signal is generated from the control unit to trigger planned protective measures if a person to be protected is detected with at least a predetermined probability.

8. A device for controlling a safety system in a vehicle, comprising:
-
at least one sensor;
an evaluation unit, coupled to an output of the at least one sensor, to supply output signals, the evaluation unit performing a frequency analysis with respect to the output signals and being integrated into a control unit, wherein the evaluation unit and the control unit perform the frequency analysis in at least one predetermined frequency range, the spectrum of the output signals are compared with reference patterns, dependence of the spectrum on the current velocity of the vehicle and/or the current outside temperature of the vehicle are accounted for, and a triggering signal is generated to trigger planned protective measures if an impact with a person to be protected is detected with at least a predetermined probability. - View Dependent Claims (9, 10, 11)

12. A method for controlling a safety system of a vehicle based on frequency analysis, comprising the acts of:
-
filtering a sensor signal to produce a signal in a predetermined frequency range;
comparing the signal in the predetermined frequency range with a reference pattern;
accounting for a vehicle velocity and/or outside temperature in the frequency analysis; and
generating a safety system control signal when a person to be protected is, based on the frequency analysis, detected with at least a predetermined probability. - View Dependent Claims (13)
