Claim:
1. A method for generating a trigger signal, comprising: generating, by a first sensor element, a first sensor signal; generating, by a second sensor element, a second sensor signal; comparing the first sensor signal with a first threshold value; comparing the second sensor signal with a second threshold value; determining a triggering criterion has been met when (i) the first sensor signal exceeds the first threshold value and (ii) the first sensor signal is recognized as plausible; and outputting a trigger signal when the triggering criterion has been met; wherein the plausibility of a sensor signal is checked by performing the following: wherein the plausibility check, which is performed based on the at least one first reliability range, detects implausible first sensor signals even if the first sensor element functions properly or is non-defective.
