Abstract

The device has a central control unit (ECU) incorporating a central sensor unit (SZ) and at least one external sensor unit for providing raw data, combined with data from the central sensor unit and compared with a threshold value for supplying a triggering signal to a triggering unit (AE1) for the passenger restraint. An Independent claim for a triggering method for an automobile passenger restraint is also included.

Description

Die Erkennung eines Seitenaufpralls im Automobil und Aktivierung der zugehörigen Sicherheitssysteme wie z. B. Seitenairbags und Curtains. Die Erkennung basiert auf der Verarbeitung der Messwerten von mehreren, über das Fahrzeug verteilten Beschleunigungssensoren. Um die optimale Auslöseentscheidung und Auslösezeit zu erreichen, werden spezielle Messwert- Verarbeitungsvorschriften benötigt. Die Verarbeitungsvorschrift (Algorithmus) ist Gegenstand dieser Erfindung. The detection of a side impact in the automobile and Activation of the associated security systems such as B. Side airbags and curtains. The detection is based on the processing the measured values of several, distributed over the vehicle Acceleration sensors. For the optimal trigger decision and tripping time, special measured value Processing instructions needed. The Processing instructions (algorithm) is the subject of this invention.

Die sogenannte "Rohdatenübertragung" von Beschleunigungswerten, d. h. die direkte Messwertübertragung (zumeist in digitaler Form) zu einer zentralen Recheneinheit mit ausreichender Bandbreite für die Crasherkennung ist ein relativ neuer Trend in der Automobiltechnik. The so - called "raw data transmission" from Acceleration values, d. H. the direct transmission of measured values (mostly in digital form) to a central processing unit with sufficient Bandwidth for crash detection is a relatively new trend in automotive engineering.

Bisher wurde die Seitencrasherkennung zumeist am Ort des Sensors durchgeführt (ohne Rohdatenübertragung). So far, the side crash detection was mostly at the location of the Sensor carried out (without raw data transfer).

Die Erfindung wird mit Hilfe der beigefügten Graphiken erläutert (Fig. 1-Fig. 4). The invention will be explained with reference to the attached graphs (Fig. 1-Fig. 4).

Die Erfindung liegt in der speziellen Kombination und Verrechnung der Eingangsdaten. The invention lies in the special combination and Allocation of input data.
