Abstract

The impact sensor has elastically deformable hose (3) having a cavity, and pressure sensor (P) for detecting the pressure change in the cavity of the hose. The inner diameter of hose is 2.5-6mm and the outer diameter of hose is less than 12mm. the hose is made of high temperature-crosslinked silicone rubber.

Description

  • Die Erfindung betrifft einen Aufprallsensor gemäß dem Oberbegriff von Anspruch 1. The invention relates to an impact 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. A motor vehicle in this case has at least one, and often several impact sensors for generating a signal dependent on the type and / or severity of the impact signal.
  • 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. An impact sensor to a suitable example, consists of an elastically deformable hose having a cavity and at least one pressure sensor for detecting the pressure change in the cavity of the hose. 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 Such crash sensors are used in motor vehicles the detection of crash situations, particularly the discrimination of an impact of a pedestrian from other impact events, and are for example from EP 937612 A2 EP 937 612 A2 bekannt. known.
  • Die Aufgabe der vorliegenden Erfindung ist es, eine besonders geeignete Ausgestaltung eines solchen Aufprallsensors anzugeben. The object of the present invention is to provide a particularly suitable embodiment of such a crash sensor. Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. This object is solved by the features of the independent claims. Vorteilhafte Weiterbildungen der Erfindung ergeben sind aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale miteinander denkbar sind. Advantageous further developments of the invention are resulting from the subclaims, with combinations of individual features and refinements are possible 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 between 2.5 and 6 millimeters and an outer diameter 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. However, such a small, thin tube proves to be particularly suitable to provide a significant pressure signal for distinguishing a pedestrian impact from an impact against a rigid obstacle, such as a post or tree lamps in the predetermined speed range. Dickere Schläuche hätten zwar eine größere Aufprallfläche, wären jedoch bei der hier erforderlichen Länge über die Breite der Stoßstange hinweg nachteilig. Although thicker tubes would have a larger impact area, but would at the required length here over the width of the bumper away disadvantageous. Vorzugsweise ist der Schlauch auch nur maximal 2,3 Meter lang. Preferably, the hose is a maximum of 2.3 meters in length.
  • Der Schlauch the hose 3 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. need not necessarily be a straight path, but can also be bent, provided 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. The invention will now be explained in more detail below using an exemplary embodiment with the aid of the figures. Im Folgenden können für funktional gleiche und/oder gleiche Elemente mit den gleichen Bezugsziffern bezeichnet sein. In the following, may be referred to functionally identical and / or same elements by the same reference numerals.

Hinter der äußeren Verkleidung Behind the outer panel 1 1 ist ein elastischer Dämpfungskörper is an elastic damping body 2 2 angeordnet, hier beispielsweise aus einem Energieabsorberschaum, beispielsweise einem expandierten Polypropylen, oder einem stark verdichteten Styropormaterial besteht. arranged here consists for example of an energy absorber foam, for example an expanded polypropylene, polystyrene or a highly compressed material. Hinter dem Dämpfungskörper Behind the damping body 2 2 ist der Querträger is the transverse beam 4 4 angeordnet. arranged. Die Steifigkeit des Dämpfungskörpers The stiffness of the damping body 2 2 und des Querträger and the crossmember 4 4 sind dabei so gewählt, dass bei Aufprall mit niedriger Geschwindigkeit vorzugsweise ausschließlich der Dämpfungskörper are chosen such that upon impact at low speed preferably exclusively the damping body 2 2 verformt wird, während der Querträger is deformed, while the cross member 4 4 kaum belastet wird. is hardly loaded. Bei Aufprallereignissen mit hoher Geschwindigkeit wird der Querträger In impact events at high speed, the cross member is 4 4 mit verformt und verteilt die Aufprallenergie auf weitere Bereiche der Fahrzeug-Karosserie. deformed and distributes the impact energy to other areas of the vehicle body. 1 1 geformt in eine Fuge des Dämpfungskörpers formed in a groove of the damping body 2 2 ist zwischen Dämpfungskörper is between the damping body 2 2 und Querträger and cross members 4 4 der elastische Schlauch the elastic tube 3 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. arranged, which extends over a length 3L of the bumper and, at least on one side, preferably connected at both sides with pressure sensors P for detecting the pressure change in the cavity of the hose.

Der Schlauchmantel ist daher vorzugsweise ca 2–3 mm dick. The hose jacket is therefore preferably about 2-3 mm thick. Die Maße dieses Schlauches The dimensions of this tube 3 3 sind überraschend klein im Verhältnis zur Größe der Stoßstange. are surprisingly small relative to the size of the bumper.
  • Der Schlauch the hose 3 3 weist eine Länge 3L von kleiner 2,3 Metern auf. has a length 3L of less than 2.3 meters. Die Länge des Schlauches wirkt sich auf die Laufzeit und das Gesamtvolumen des Hohlraums im Inneren des Schlauchs aus. The length of the hose has an effect on the running time and the total volume of the cavity inside the tube.
  • Der Schlauch the hose 3 3 muss nicht zwingend gerade verlegt werden, sondern kann auch gebogen werden, sofern ein Biegeradius von mindestens 10, vorzugsweise 25 mm eingehalten wird. need not necessarily be a straight path, but may also be curved, provided that a bending radius of at least 10, preferably 25 mm is maintained.
