Apparatus for triggering restraint devices
First Claim
Patent Images
1. An apparatus for triggering a restraint device, comprising:
- a control unit directly connected to a plurality of crash sensors; and
at least one vehicle sensor located outside of the control unit, as a component within a control system that is connected to the control unit and controls a vehicle function other than triggering of the restraint device;
wherein the control unit is configured to check a crash signal generated by a first one of the plurality of crash sensors against a plausibility signal generated in response to an earliest-occurring one of (i) a crash signal from another one of the plurality of crash sensors, and (ii) a crash signal from the control system, the control unit triggering the restraint device when both the crash signal generated by the first one of the plurality of crash sensors and the plausibility signal are present.

Abstract
An apparatus for triggering restraint devices includes crash sensors inside and outside of a control unit. The apparatus checks a crash signal of the crash sensors using a plausibility signal. To check the crash signal, the apparatus receives the plausibility signal from a vehicle sensor outside of the control unit, and then triggers the restraint devices as a function of the crash signal and the first plausibility signal.

6. An apparatus for triggering a restraint device, comprising:
-
control means directly connected to a plurality of crash sensing means; and at least one vehicle sensing means located outside of the control means, as a component within an additional control means that is connected to the control means and controls a vehicle function other than triggering of the restraint device; wherein the control means is for checking a crash signal generated by a first one of the plurality of crash sensing means against a plausibility signal generated in response to an earliest-occurring one of (i) a crash signal from another one of the plurality of crash sensing means, and (ii) a crash signal from the additional control means, the control means triggering the restraint device when both the crash signal generated by the first one of the plurality of crash sensing means and the plausibility signal are present.
