ABSTRACT:
A device for acceleration measurement, in which measuring signals from a two-dimensional sensor from measuring different directions are combined (gated) with one another and then jointly evaluated in an evaluation circuit. This evaluation is carried out, for example, using a threshold-value discriminator, in order to perform a plausibility check for a crash detection.
