Patent ID: 8655552

Claim:
A control device for triggering a passenger protection arrangement for a vehicle, comprising: a first interface providing at least two acceleration signals in at least two acceleration sensors oriented in different spatial directions, wherein each of the at least two acceleration sensors is oriented at a non-zero angle relative to both a horizontal axis and a vertical axis of a two-dimensional coordinate system in which the vertical axis lies along a vehicle longitudinal direction and the horizontal axis lies along a vehicle transverse direction; an evaluation circuit having a transformer module that transforms the at least two acceleration signals to corresponding acceleration signals along the horizontal and vertical axes of the coordinate system, and a comparison module that generates a triggering signal as a function of a comparison of the at least two acceleration signals and the corresponding transformed acceleration signals; and a triggering circuit that triggers the passenger protection arrangement as a function of the triggering signal; wherein the comparison module imposes a first condition in which the triggering signal is only generated in response to a determination that a scaled version of any of the transformed acceleration signals is smaller than one of the at least two acceleration signals from which the transformed acceleration signal was derived.
