Description
Aufprallsensor bestehend aus zumindest zwei deformierbaren Hohlkörpern und zumindest jeweils einem Drucksensor Impact sensor consisting of at least two deformable hollow bodies and at least one pressure sensor
Die Erfindung betrifft einen Aufprallsensor bestehend aus zumindest zwei deformierbaren Hohlkörpern und zumindest jeweils einem Drucksensor gemäß dem Oberbegriff von Anspruch 1 sowie ein entsprechendes Verfahren zur Auswertung. The invention relates to an impact sensor consisting of at least two deformable hollow bodies and at least one respective pressure sensor according to the preamble of claim 1 and a corresponding method for evaluation.
Ein derartiger Aufprallsensor ist beispielsweise aus der EP 937612 A2 bekannt. Durch die zwei separaten Schläuche kann die Druckmessung der beiden Sensoren gegeneinander plausibilisiert und aus den Laufzeitunterschieden zu den beiden an entgegengesetzten Seiten des Fahrzeugs angeordneten Drucksensoren auf die Position des Auftreffens geschlossen werden. Der Aufwand für die Montage und Verkabelung erhöht sich dadurch erheblich. Darüber hinaus sind beispielsweise aus der EP 1281582 Aufprallsensoren mit mehreren Hohlkörpern und einem gemeinsamen Drucksensor bekannt, wobei damit bereits keine Möglichkeit der Plausibilisierung mehr besteht. Such an impact sensor is known, for example, from EP 937612 A2. By means of the two separate hoses, the pressure measurement of the two sensors can be made plausible against one another and the position of the impact can be deduced from the transit time differences with respect to the two pressure sensors arranged on opposite sides of the vehicle. The effort for assembly and wiring increases considerably. In addition, impact sensors with a plurality of hollow bodies and a common pressure sensor are known, for example, from EP 1281582, whereby there is no longer any possibility of a plausibility check.
Aus der DE 10309713 A1 ist eine Aufprallsensoreinheit zu entnehmen, bei welcher zwei jeweils sowohl für Druck als auch Beschleunigung empfindliche Sensoren jeweils auf entgegengesetzten Seiten im Inneren des Hohlraums angeordnet sind. DE 10309713 A1 discloses an impact sensor unit in which two sensors sensitive to both pressure and acceleration are respectively arranged on opposite sides in the interior of the cavity.
Aus der DE 10 2004 022 591 A1 ist eine Aufprallsensoreinheit zu entnehmen, bei welcher jeweils ein Drucksensor jeweils in Inneren seines eigenen Hohlraums angeordnet ist. From DE 10 2004 022 591 A1 a collision sensor unit can be seen, in which in each case a pressure sensor is arranged in each case in the interior of its own cavity.
Auch bei diesen Lösungen ist der Aufwand für die Montage und Verkabelung hoch. Even with these solutions, the cost of assembly and wiring is high.
Die Aufgabe der vorliegenden Erfindung ist es daher, einen Aufprallsensor vorzustellen, der bei niedrigem Montageaufwand dennoch eine Plausibilisierung ermöglicht. The object of the present invention is therefore to present an impact sensor, which nevertheless allows a plausibility check with low assembly costs.
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. Ein wesentlicher Gedanke der Erfindung besteht darin, dass die zwei Drucksensoren in einem gemeinsamen Gehäuse, also einer gemeinsamen Elektronikbaugruppe mit einem gemeinsamen Schaltungsträger, angeordnet und im Gehäuse gegeneinander abgedichtet, also für jeden Drucksensor ein gegen den anderen abgedichteter Druckzuleitungsbereich vorgesehen ist. Durch das gemeinsame Gehäuse reduziert sich jedoch nicht nur der Aufwand für dieses Gehäuse, sondern wird auch nur noch eine Zuleitung zu Auswerteeinheit benötigt und reduziert sich damit der Aufwand für Montage und Verkabelung. Derartige Aufprallsensoren oder zumindest deren Hohlkörper werden beispielsweise in der Stoßstange vorne und evt. auch hinten am Heck integriert und dienen zur Aufprallerkennung für die Auslösung von Fußgängerschutzeinrichtungen oder auch Insassenschutzeinrichtungen. 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. An essential idea of the invention is that the two pressure sensors are arranged in a common housing, that is to say a common electronic subassembly having a common circuit carrier, and sealed against one another in the housing, that is to say that for each pressure sensor a pressure supply area sealed against the other is provided. Due to the common housing, however, not only reduces the cost of this case, but also only one lead to evaluation needs and thus reduces the cost of installation and wiring. Such impact sensors or at least their hollow bodies are integrated, for example, in the bumper in the front and possibly also at the rear of the rear and serve for impact detection for the release of pedestrian protection devices or occupant protection devices.
Indem die Drucksensoren auf einem gemeinsamen Schaltungsträger angeordnet sind, ist also auch nur noch ein gemeinsamer Schaltungsträger erforderlich. Dies eröffnet wiederum die Möglichkeit, auf diesem Schaltungsträger eine gemeinsame Einheit zur Energiezuführung an die Drucksensoren und/oder eine gemeinsame Einheit zur Signalweiterleitung an eine mit dem Aufprallsensor verbindbare Auswerteeinheit gemeinsam für beide Drucksensoren zu nutzen. By the pressure sensors are arranged on a common circuit carrier, so only one common circuit carrier is required. This, in turn, opens up the possibility of jointly using a common unit for supplying energy to the pressure sensors and / or a common unit for signal forwarding to an evaluation unit which can be connected to the impact sensor, for both pressure sensors, on this circuit carrier.
Die Erfindung wird nun nachfolgend anhand eines Ausführungsbeispieles unter Zuhilfenahme der Figuren näher erläutert. Im Folgenden können für funktional gleiche und/oder gleiche Elemente mit den gleichen Bezugsziffern bezeichnet sein. Es zeigen The invention will now be explained in more detail using an exemplary embodiment with the aid of the figures. Hereinafter, for functionally identical and / or identical elements may be denoted by the same reference numerals. Show it
Figur 1 : Skizze eines erfindungsgemäßen Aufprallsensors Figure 1: Sketch of a crash sensor according to the invention
Figur 2: Skizzierung eines Auswertealgorithmus auf Basis dieser beiden Sensoren FIG. 2: Sketching of an evaluation algorithm on the basis of these two sensors
Figur 1 zeigt einen Aufprallsensor aus zumindest zwei deformierbaren Hohlkörpern 2.a und 2.b sowie zumindest jeweils einem, in diesem Ausführungsbeispiel also 2 Drucksensoren 1 .2.a, 1.2.b zur Erfassung der Druckänderung im jeweiligen Hohlkörper. Würde eine größere Anzahl an Hohlkörpern verwendet werden, wäre entsprechend die Anzahl der Drucksensoren ebenfalls zu erhöhen. Diese Drucksensoren 1.2.a, 1.2.b sind in einem gemeinsamen Gehäuse 1 und auf einem gemeinsamen Schaltungsträger 1 .1 angeordnet, wobei im Gehäuse für jeden Drucksensor ein gegen den anderen abgedichteter Druckzuleitungsbereich 1 .3.a, 1.3b vorgesehen ist. So wie jeder Hohlkörper 2.a und 2.b voneinander getrennt ist, sind auch die Druckzuleitungsbereiche 1 .3.a, 1.3b voneinander getrennt, wobei für die konkrete Ausgestaltung unterschiedlichen Möglichkeiten, beispielsweise auch eine gemeinsame Trennwand zwischen den beiden Druckzuleitungsbereichen denkbar ist und die Figur 1 diesbezüglich keinesfalls als einzig denkbare Alternative zu verstehen ist. Ebenfalls in nur einem denkbaren Beispiel ist der Abschluss 3 der Hohlkörper auf der dem Gehäuse entgegengesetzten Seite dargestellt. So kann anstelle eines gemeinsamen Abschlussstopfens für beide Hohlkörper auch eine andere Trennung vorgesehen werden, beispielsweise die beiden Hohlkörper auch aus einem gemeinsamen Schlauch gebildet werden, welcher dann auf dieser, dem Gehäuse 1 entgegengesetzten Seite durch Klemmmittel oder andere technische Lösungen in 2 druckmäßig voneinander getrennte Hohlkörper unterteilt wird. FIG. 1 shows an impact sensor comprising at least two deformable hollow bodies 2. A and 2. B and at least one, in this exemplary embodiment, 2 pressure sensors 1 .2. A, 1. 1 b for detecting the pressure change in the respective hollow body. Would a larger number of hollow bodies are used, the number of pressure sensors would also increase accordingly. These pressure sensors 1.2.a, 1.2.b are arranged in a common housing 1 and on a common circuit carrier 1 .1, wherein in the housing for each pressure sensor a sealed against the other pressure supply area 1 .3a, 1.3b is provided. Just as each hollow body 2.a and 2.b is separated from each other, the pressure supply areas are also 1 .3a, 1.3b separated from each other, for the specific embodiment of different possibilities, for example, a common partition between the two pressure supply areas is conceivable and Figure 1 in this regard, by no means as unique conceivable alternative to understand. Also in only one conceivable example, the conclusion 3 of the hollow body is shown on the opposite side of the housing. Thus, instead of a common end plug for both hollow body, a different separation may be provided, for example, the two hollow bodies are formed from a common tube, which then on this, the housing 1 opposite side by clamping means or other technical solutions in 2 pressure moderately separate hollow body is divided.
Derartige Aufprallsensoren oder zumindest deren Hohlkörper werden beispielsweise in der Stoßstange vorne und evt. auch hinten am Heck integriert und dienen zur Aufprallerkennung für die Auslösung von Fußgängerschutzeinrichtungen oder auch Insassenschutzeinrichtungen. Such impact sensors or at least their hollow bodies are integrated, for example, in the bumper in the front and possibly also at the rear of the rear and serve for impact detection for the release of pedestrian protection devices or occupant protection devices.
In der Figur 1 nicht im Detail gezeigt, jedoch als bevorzugte Ausgestaltung zu verstehen ist auf dem Schaltungsträger 1.1 eine gemeinsame Einheit zur Energiezuführung an die Drucksensoren 1 .2.a, 1.2.b als auch eine gemeinsame Einheit zur Signalweiterleitung an eine mit dem Aufprallsensor verbindbare Auswerteeinheit 4 vorgesehen. Dadurch können neben den Materialaufwand für den Schaltungsträger 1 .1 auch in erheblichem Maße Kosten für die elektronischen Bauelemente reduziert oder sogar die beiden Drucksensoren und der Schaltungsträger zu einem gemeinsamen ASIC mit 2 drucksensitiven Bereichen und allen anderen erforderlichen elektronischen Einheiten integriert werden. Not shown in detail in FIG. 1, but to be understood as a preferred embodiment, a common unit for supplying energy to the pressure sensors 1 .2.a, 1.2.b as well as a common unit for signal forwarding to a connectable to the impact sensor on the circuit substrate 1.1 Evaluation unit 4 is provided. As a result, in addition to the cost of materials for the circuit substrate 1 .1 can also be reduced to a considerable extent costs for the electronic components or even the two pressure sensors and the circuit board to a common ASIC with 2 pressure-sensitive areas and all other required electronic units are integrated.
Es ist also eine doppelte Ausführung des Hohlkörpers, hier ausgestaltet als Schlauch vorgesehen, wobei jeweils ein Drucksensor die Druckänderungen in genau einem Schlauch detektiert. Somit ist sichergestellt, dass Beschädigungen eines Schlauches im Falle einer Druckänderung detektiert werden können, da diese Druckänderung im betreffenden Schlauch entsprechend geringer bzw. kürzer wird ausfallen. Das System kann darauf so antworten, dass in diesem Fall immer die größere / längere Druckänderung ausgewertet wird. Die elektrische Anbindung der Sensoren an die Auswerteeinheit 4 erfolgt bevorzugt vom gemeinsamen Gehäuse 1 aus über die gemeinsame Anschlussleitung. It is therefore a double design of the hollow body, designed here designed as a hose, wherein in each case a pressure sensor detects the pressure changes in exactly one hose. This ensures that damage to a hose can be detected in the event of a pressure change, since this change in pressure in the relevant hose will be correspondingly shorter or shorter. The system can respond in such a way that in this case always the larger / longer pressure change is evaluated. The electrical connection of the sensors to the evaluation unit 4 preferably takes place from the common housing 1 via the common connection line.
Die beiden Drucksensoren liefern die Drucksignale p1 und p2. nun wird die Differenz des Drucks |p1 - p2| zwischen beiden Drucksignalen p1 und p2 bestimmt. Überschreitet der Druckunterschied einen zu definierenden Wert X, dann wird geschlussfolgert, dass der eine Sensor oder der entsprechende Schlauch defekt ist. In diesem Fall wird das Signal mit der absolut größeren Amplitude als relevantes Drucksignal für die weitere Signalbewertung verwendet. Im ungestörten Betrieb kann man als relevantes Drucksignal prel entweder den Mittelwert beider Sensorsignale verwenden, oder alternativ - im Sinne einer besonders kosteneffizienten Implementierung - nur eines der zwei Sensorsignale.The two pressure sensors deliver the pressure signals p1 and p2. now the difference of the pressure | p1 - p2 | determined between the two pressure signals p1 and p2. If the pressure difference exceeds a value X to be defined, then it is concluded that the one sensor or the corresponding hose is defective. In this case, the signal with the absolute larger amplitude is used as a relevant pressure signal for the further signal evaluation. In undisturbed operation can be as a relevant pressure signal prel use either the mean of both sensor signals, or alternatively - in the sense of a particularly cost-effective implementation - only one of the two sensor signals.
Auf Basis des für den Algorithmus relevanten Drucksignals prel wird entschieden, ob z.B. ein Fußgängeraufprall vorliegt. Hierfür gibt es eine Reihe von Parametern aus dem Druck Signal, beispielsweise die Amplitude und Dauer eines Druckimpulses. On the basis of the pressure signal prel relevant to the algorithm, it is decided whether e.g. a pedestrian impact is present. For this purpose, there are a number of parameters from the pressure signal, for example, the amplitude and duration of a pressure pulse.
