In addition, a suitable hose and an impact sensor for a motor vehicle with such a hose are presented.
Description
Die Erfindung betrifft Verfahren zur Erkennung der Lage eines Schlauchs hinter zumindest einer äußeren Abdeckung eines Fahrzeugs gemäß dem Oberbegriff von Anspruch 1. Zudem wird ein Aufprallsensor mit einem Schlauch vorgestellt, welcher geeignet für die Durchführung des Verfahrens ist. The invention relates to methods for detecting the position of a hose behind at least one outer cover of a vehicle according to the preamble of claim 1. In addition, an impact sensor with a hose is presented, which is suitable for carrying out the method.
In Fahrzeugen werden heutzutage eine Vielzahl von Schläuchen verbaut, welche in der Regel hinter einer äußeren Abdeckung, also beispielsweise einem Blech oder Kunststoff des Fahrzeuggehäuses liegen. Für eine Reihe von Anwendungen ist die konkrete Positionierung und Erkennung der Lage des Schlauchs hinter dieser Abdeckung für die Sicherstellung der Funktionsbereitschaft erforderlich, andererseits aber das abnehmen dieser äußeren Abdeckung oft nicht mehr oder nur mit unverhältnismäßig großem Aufwand möglich. In vehicles today, a plurality of hoses are installed, which are usually behind an outer cover, so for example, a sheet or plastic of the vehicle body. For a number of applications, the specific positioning and detection of the position of the hose behind this cover for ensuring the operational readiness is required, but on the other hand, the removal of this outer cover is often no longer possible or only with disproportionate effort.
So ist beispielsweise aus der
Die Aufgabe der vorliegenden Erfindung ist es daher, ein geeignetes Verfahren zur Erkennung der Lage eines Schlauches vorzustellen. Zudem wird ein Schlauch sowie ein Aufprallsensor zur Durchführung dieses Verfahrens beschrieben. The object of the present invention is therefore to present a suitable method for detecting the position of a hose. In addition, a hose and an impact sensor for carrying out this method will be described.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, wobei auch Kombinationen und Weiterbildungen einzelner Merkmale miteinander denkbar sind. This object is solved by the features of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims, and combinations and developments of individual features are conceivable with each other.
Ein wesentlicher Gedanke der Erfindung besteht darin, dass eine Positionserkennungsvorrichtung vorgesehen ist, welche eine die äußere Abdeckung durchdringende Strahlung erzeugt und der Schlauch ein Kontrastmittel aufweist, welches diese Strahlung zumindest teilweise reflektiert bzw. absorbiert und die Positionserkennungsvorrichtung dies erfasst. So ist es möglich, beispielsweise den richtigen Verbau des so genannten PPS-pSAT-Sensorsystems, also eines Aufprallsensors für ein Sicherheitssystem in Kraftfahrzeugen mit einem Schlauch und zumindest einem Drucksensor, zu kontrollieren, wenn dieser in einen Energie-Absorber-Schaum eingespritzt verbaut werden soll, und somit von außen (optisch) nicht mehr geprüft werden kann. Selbst eine Quetschung oder Verschiebung des Schlauches oder Knick im Schlauch kann erkannt werden. An essential idea of the invention is that a position detection device is provided which generates a radiation penetrating the outer cover and the tube has a contrast agent which at least partially reflects or absorbs this radiation and the position detection device detects this. Thus, it is possible to control, for example, the correct installation of the so-called PPS-pSAT sensor system, that is to say a crash sensor for a safety system in motor vehicles with a hose and at least one pressure sensor, if this is to be installed injected into an energy absorber foam , and thus from the outside (visually) can not be checked. Even a pinch or displacement of the hose or kink in the hose can be detected.
Als Strahlung wird beispielsweise Röntgenstrahlung verwendet. Durch Beimischung von schweren Atomen (bzw. chemischen Verbindungen, welche schwere Atome enthalten, kann die Position erkannt werden. Inbesondere Barium und Ytterbium haben sich hierzu bewährt. Seit kurzem wird auch der Einsatz von Nanoparikeln (aus Batiumsulfat oder Ytterbiumflurid) untersucht. As radiation, for example, X-rays are used. By incorporation of heavy atoms (or chemical compounds containing heavy atoms), the position can be recognized, with barium and ytterbium in particular, and recently the use of nanoparticles (from batesulfate or ytterbiumflurid) has also been investigated.
Als Strahlung wird alternativ auch eine hochfrequente elektromagnetische Strahlung, vorzugsweise im Terahertz-Bereich betrachtet. Sowohl Poylpropylen (PP) als auch Silikon (PDMS) sind für Teraherzstrahlung sehr transparent. Durch Beimischung leitfähiger Partikel oder Fasern (Metall, Kohlenstoff) in das Schlauchmaterial kann die Absorption verstärkt werden. In der Medizin-Technik werden Gadolinium-Verbindungen auch als Kontrastmittel für Teraherzstrahlung verwendet. Durch Beimischung solcher Stoffe in das Schlauchmaterial kann die Lage des Schlauchs erkannt werden. As radiation is alternatively considered a high-frequency electromagnetic radiation, preferably in the terahertz range. Both polypropylene (PP) and silicone (PDMS) are very transparent to terahertz radiation. By incorporating conductive particles or fibers (metal, carbon) into the tubing, the absorption can be enhanced. In medicine, gadolinium compounds are also used as contrast agents for terahertz radiation. By admixing such substances in the tubing, the position of the tube can be detected.
Vorzugsweise ist dabei das Kontrastmittel im Material des Schlauchs gleichmäßig mit einer vorgegebenen Konzentration verteilt angeordnet und wird durch die Positionserkennungsvorrichtung auch eine eventuell veränderte Verteilung des Kontrastmittels erkannt und daraus auf Quetschungen oder Streckungen des Schlauchs geschlossen. Preferably, the contrast agent in the material of the tube is uniformly distributed with a predetermined concentration and is detected by the position detection device, a possibly changed distribution of the contrast agent and closed it on bruises or stretching of the hose.
Es könnte z.B. auch mit einem Lack aus Silberpartikel (sehr leitfähig und damit stark absorbierend für Teraherz) die Mitte des Schlauches markiert werden. So könnte man überprüfen, ob der Schlauch mittig verlegt wurde. It could e.g. also with a paint of silver particles (very conductive and thus strongly absorbing for Teraherz) the middle of the hose are marked. So you could check if the tube was laid in the middle.
Solche Markierungen könnten auch über die ganze Schlauchlänge (z.B jeden Zentimeter) angebracht werden. Damit könnte über die ganze Schlauchlänge eine Zug-/Stauchungsfreie Verlegung nachgewiesen werden. Such markings could also be applied over the entire hose length (for example every centimeter). This could be demonstrated over the entire hose length of a train / compression-free installation.
Dementsprechend wird also ein Schlauch für eine Anordnung hinter einer äußeren Abdeckung eines Kraftfahrzeugs beschrieben, welcher geeignet zur Durchführung dieses Verfahrens ist und dazu ein Kontrastmittel aufweist, welches eine vorgegebene Strahlung zumindest teilweise reflektiert bzw. absorbiert. Accordingly, therefore, a hose is described for an arrangement behind an outer cover of a motor vehicle, which is suitable for carrying out this method and for this purpose has a contrast agent which at least partially reflects or absorbs a predetermined radiation.
Eine bevorzugte Anwendung ist vorgesehen bei einem Aufprallsensor bestehend aus einem bei einem Aufprall elastisch deformierbaren Schlauch mit einem Hohlraum und zumindest einem Drucksensor zur Erfassung der Druckänderung im Hohlraum des Schlauchs, wobei der Schlauch wiederum ein entsprechendes Kontrastmittel aufweist. Ein solcher Aufprallsensor eignet sich beispielsweise für die Verwendung in der Stoßstange eines Kraftfahrzeugs. A preferred application is provided in an impact sensor consisting of an elastically deformable in an impact hose with a cavity and at least one pressure sensor for detecting the change in pressure in the cavity of the hose, wherein the hose in turn has a corresponding contrast agent. Such an impact sensor is suitable, for example, for use in the bumper of a motor vehicle.
