Description

Die Erfindung betrifft einen Aufprallsensor gemäß dem Oberbegriff von Anspruch 1.The invention relates to a crash sensor according to the preamble of claim 1.

Ein Kraftfahrzeug weist dabei mindestens einen, oft auch mehrere Aufprallsensoren zur Erzeugung eines von der Art und/oder Stärke des Aufpralls abhängigen Signals auf.In this case, a motor vehicle has at least one, often also a plurality of impact sensors for generating a signal which depends on the type and / or magnitude of the impact.

Ein dazu geeigneter Aufprallsensor besteht beispielsweise aus einem elastisch deformierbaren Schlauch mit einem Hohlraum und zumindest einem Drucksensor zur Erfassung der Druckänderung im Hohlraum des Schlauchs. Derartige Aufprallsensoren dienen in Kraftfahrzeugen der Erkennung von Aufprallsituationen, insbesondere auch der Unterscheidung eines Aufpralls eines Fußgängers von anderen Aufprallereignissen und sind beispielsweise aus der EP 937612 A2 bekannt.A suitable impact sensor consists for example of an elastically deformable hose with a cavity and at least one pressure sensor for detecting the change in pressure in the cavity of the hose. Such impact sensors are used in motor vehicles to detect impact situations, in particular the distinction of a collision of a pedestrian from other impact events and are for example from the EP 937612 A2 known.

Die Aufgabe der vorliegenden Erfindung ist es, eine besonders geeignete Ausgestaltung eines solchen Aufprallsensors anzugeben. Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sind aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale miteinander denkbar sind.The object of the present invention is to provide a particularly suitable embodiment of such an impact sensor. This object is solved by the features of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims, wherein combinations and developments of individual features are conceivable with each other.

Ein wesentlicher Gedanke der Erfindung besteht darin, dass der Schlauch des Aufprallsensors einen Innendurchmesser zwischen 2,5 und 6 Millimeter und einen Außendurchmesser kleiner 12 Millimeter aufweist.An essential idea of the invention is that the hose of the impact sensor has an inner diameter of between 2.5 and 6 millimeters and an outer diameter of less than 12 millimeters.

Ein so kleiner, dünner Schlauch erweist sich jedoch als besonders geeignet, um ein signifikantes Drucksignal zur Unterscheidung eines Fußgängeraufpralls von einem Aufprall gegen ein starres Hindernis, beispielsweise einen Laternen-Pfosten oder Baum in den vorgegebenen Geschwindigkeitsbereich bereitzustellen. Dickere Schläuche hätten zwar eine größere Aufprallfläche, wären jedoch bei der hier erforderlichen Länge über die Breite der Stoßstange hinweg nachteilig. Vorzugsweise ist der Schlauch auch nur maximal 2,3 Meter lang.However, such a small, thin tube proves to be particularly suitable for providing a significant pressure signal for distinguishing a pedestrian impact from impact with a rigid obstacle such as a lantern post or tree within the given speed range. Although thicker hoses would have a larger impact surface, but would be at the length required here across the width of the bumper away disadvantageous. Preferably, the hose is only a maximum of 2.3 meters long.

Der Schlauch 3 muss nicht zwingend gerade verlegt werden, sondern kann auch gebogen werden, sofern ein Biegeradius von mindestens 10, vorzugsweise mehr als 25 mm eingehalten wird.The hose 3 not necessarily straight, but can also be bent, provided that a bending radius of at least 10, preferably more than 25 mm is maintained.

Die Erfindung wird nun nachfolgend anhand eines Ausführungsbeispiels unter Zuhilfenahme der Figuren näher erläutert. Im Folgenden können für funktional gleiche und/oder gleiche Elemente mit den gleichen Bezugsziffern bezeichnet sein.The invention will now be explained in more detail below with reference to an embodiment with the aid of the figures. Hereinafter, for functionally identical and / or identical elements may be denoted by the same reference numerals.

1 zeigt eine vordere Stoßstange eines Kraftfahrzeugs mit einer äußeren Verkleidung 1, beispielsweise einem Metallblech oder einem Kunststoffformteil. Hinter der äußeren Verkleidung 1 ist ein elastischer Dämpfungskörper 2 angeordnet, hier beispielsweise aus einem Energieabsorberschaum, beispielsweise einem expandierten Polypropylen, oder einem stark verdichteten Styropormaterial besteht. Hinter dem Dämpfungskörper 2 ist der Querträger 4 angeordnet. Die Steifigkeit des Dämpfungskörpers 2 und des Querträger 4 sind dabei so gewählt, dass bei Aufprall mit niedriger Geschwindigkeit vorzugsweise ausschließlich der Dämpfungskörper 2 verformt wird, während der Querträger 4 kaum belastet wird. Bei Aufprallereignissen mit hoher Geschwindigkeit wird der Querträger 4 mit verformt und verteilt die Aufprallenergie auf weitere Bereiche der Fahrzeug-Karosserie. 1 geformt in eine Fuge des Dämpfungskörpers 2 ist zwischen Dämpfungskörper 2 und Querträger 4 der elastische Schlauch 3 angeordnet, welcher sich über eine Länge 3L der Stossstange erstreckt und zumindest an einer Seite, vorzugsweise an beiden Seiten mit Druck-Sensoren P zur Erfassung der Druckänderung im Hohlraum des Schlauchs verbunden ist. 1 shows a front bumper of a motor vehicle with an outer panel 1 , For example, a metal sheet or a plastic molding. Behind the outer panel 1 is an elastic damping body 2 arranged here, for example, from an energy absorber foam, for example an expanded polypropylene, or a highly compressed polystyrene material consists. Behind the damping body 2 is the crossbeam 4 arranged. The stiffness of the damping body 2 and the cross member 4 are chosen so that when impact at low speed, preferably only the damping body 2 is deformed while the cross member 4 is hardly charged. In high-speed impact events, the cross member becomes 4 with deformed and distributed the impact energy to other areas of the vehicle body. 1 shaped into a joint of the damping body 2 is between damping body 2 and crossbeams 4 the elastic hose 3 arranged, which extends over a length 3L of the bumper and is connected at least on one side, preferably on both sides with pressure sensors P for detecting the pressure change in the cavity of the hose.

Wie 2 skizziert, weist der Schlauch 3 dabei einen Innendurchmesser 3i zwischen 2,5 und 6 Millimeter, vorzugsweise ca 4 mm und einen Außendurchmesser 3a kleiner 12 Millimeter, vorzugsweise 8 mm auf. Der Schlauchmantel ist daher vorzugsweise ca 2–3 mm dick. Die Maße dieses Schlauches 3 sind überraschend klein im Verhältnis zur Größe der Stoßstange.As 2 Outlined, the hose points 3 while an inner diameter 3i between 2.5 and 6 millimeters, preferably about 4 mm and an outer diameter 3a less than 12 millimeters, preferably 8 mm. The hose jacket is therefore preferably about 2-3 mm thick. The dimensions of this hose 3 are surprisingly small in relation to the size of the bumper.

Der Schlauch 3 weist eine Länge 3L von kleiner 2,3 Metern auf. Die Länge des Schlauches wirkt sich auf die Laufzeit und das Gesamtvolumen des Hohlraums im Inneren des Schlauchs aus.The hose 3 has a length 3L of less than 2.3 meters. The length of the hose affects the running time and the total volume of the cavity inside the hose.

Der Schlauch 3 muss nicht zwingend gerade verlegt werden, sondern kann auch gebogen werden, sofern ein Biegeradius von mindestens 10, vorzugsweise 25 mm eingehalten wird.The hose 3 not necessarily straight, but can also be bent, provided that a bending radius of at least 10, preferably 25 mm is maintained.

Dieser Schlauch 3 besteht aus einem vernetzten Silikonmaterial, insbesondere einem Hochtemperatur-Silikonkautschuk und weist eine Shore A-Härte von 60 ± 5 gemäß DIN53505 sowie eine Dichte gemäß DIN 53479 ISO/R 1183 von 1,16 ± 0,05 g/cm3 und eine Reißfestigkeit gemäß DIN 53504 ISO/DIS 37 von größer 9 MPa auf.This hose 3 consists of a cross-linked silicone material, in particular a high-temperature silicone rubber and has a Shore A Hardness of 60 ± 5 according to DIN53505 and a density according to DIN 53479 ISO / R 1183 of 1.16 ± 0.05 g / cm 3 and a tear strength according to DIN 53504 ISO / DIS 37 greater than 9 MPa.

Der Schlauch 3 ist vorzugsweise mit Luft gefüllt, wobei alternativ auch eine Füllung mit anderen Gasen oder auch Flüssigkeiten denkbar sind. Über das Gehäuse des Drucksensors erfolgt vorzugsweise verzögert ein Druckausgleich gegenüber der Umgebung.The hose 3 is preferably filled with air, and alternatively a filling with other gases or liquids are conceivable. About the housing of the pressure sensor is preferably delayed, a pressure equalization with respect to the environment.

3 skizziert nochmal im Querschnitt die Stoßstange mit dem Aufprallsensor im unbelasteten Zustand, also vor einem Aufprall. Trifft im Vergleich dazu in 4 eine durch den Pfeil angedeutete Kraft durch einen Aufprall eines Fußgängers oder eines anderen Kollisionsobjekts auf die Stoßstange, so verformt sich neben der äußeren Verkleidung 1 auch der Dämpfungskörper 2 und wird dabei der Schlauch 3 entsprechend mit verformt und gegen den Querträger 4 gedrückt. Die Druckänderung im Hohlraum des Schlauchs ist bei einem solchen Schlauch aus Silikonkautschuk mit diesen Abmaßen sehr gut geeignet, um den Aufprall eines Fußgängers zu erkennen und vorzugsweise auch von anderen, steiferen Aufprallobjekten zu unterscheiden. 3 again sketched in cross-section the bumper with the impact sensor in the unloaded state, ie before an impact. Matches in comparison 4 an indicated by the arrow force by a collision of a pedestrian or other collision object on the bumper, so deformed next to the outer panel 1 also the damping body 2 and becomes thereby the hose 3 accordingly with deformed and against the cross member 4 pressed. The pressure change in the cavity of the tube is very well suited to such a tube of silicone rubber with these dimensions to recognize the impact of a pedestrian and preferably to distinguish it from other, more rigid impact objects.
