Configuration for controlling an occupant restraint device in a motor vehicle
First Claim
Patent Images
1. A configuration for controlling an occupant restraint device of a motor vehicle, comprising:
- two acceleration sensors including a first acceleration sensor outputting a first acceleration signal and a second acceleration sensor outputting a second acceleration signal, said first acceleration sensor having a first sensitivity axis for picking up longitudinal vehicle accelerations and said second acceleration sensor having a second sensitivity axis oriented substantially transversely to said first sensitivity axis of said first acceleration sensor; and
an evaluator receiving the first acceleration signal and the second acceleration signal from said two acceleration sensors, said evaluator generating a first enable signal dependent at least on the first acceleration signal, and said evaluator generating a second enable signal dependent solely on the second acceleration signal, a tripping of the occupant restraint device initiated only if both the first enable signal and the second enable signal occur simultaneously.

Abstract
A configuration for controlling an occupant restraint device of a motor vehicle. The occupant restraint device is activated only whenever it is ascertained, by an evaluator, that simultaneously a signal of a first acceleration sensor and a signal of a second acceleration sensor indicate a collision. The sensitivity axes of the acceleration sensors are oriented differently.
