Abstract
Description
Die Erfindung betrifft eine Fußgängerschutzvorrichtung für ein Kraftfahrzeug, mit einer zwischen einer Außenwand und einem biegesteifen Stützteil angeordneten Dämpfungseinrichtung, die ein stoßabsorbierendes Material zur Energieaufnahme bei einem Aufprall umfaßt, und mit einer elektrischen Sensoreinrichtung, die wenigstens einen Sensor zur Detektierung des Aufpralls umfaßt.The invention relates to a pedestrian protection device for a Motor vehicle, with one between an outer wall and a rigid Support part arranged Damping device, which is a shock absorbing Material for energy absorption in the event of an impact, and with an electrical sensor device, the at least one sensor includes to detect the impact.
Solche Vorrichtungen sind zunehmend in vorderen Stoßfängern von Fahrzeugen vorgesehen. In diesem Fall entspricht die Außenwand der Vorrichtung der Verkleidung des Stoßfängers. Als stoßabsorbierendes Material wird in der Regel ein weicher Schaum verwendet. Die elektrische Sensoreinrichtung dient dazu, einen Aufprall zu erkennen und in Ergänzung zur passiven Energieaufnahme durch das stoßabsorbierende Material zusätzliche aktive Schutzmaßnahmen für den Fußgänger einzuleiten, wie etwa ein Aufstellen der Motorhaube oder ein Auslösen eines externen Windschutzscheibenairbags. Für die Detektierung des Aufpralls werden beispielsweise kraft- bzw. druckabhängige Sensoren eingesetzt.Such devices are increasing in front bumpers from Vehicles provided. In this case, the outer wall corresponds the device of the lining of the bumper. As a shock absorbing Material is usually a soft foam. The electrical Sensor device is used to detect an impact and in addition to passive energy absorption by the shock absorbing material additional active protective measures for the Initiate pedestrians how for example, opening the bonnet or triggering an external windshield airbag. For detection the impact becomes, for example, force- or pressure-dependent sensors used.
Bei der Integration von Sensoren in die Dämpfungseinrichtung über die gesamte Fahrzeugbreite ergibt sich aber das Problem eines inhomogenen Sensierungsprofils, d.h. bei gleichen Aufprallparametern (beschleunigte Masse, relative Aufprallgeschwindigkeit) werden unterschiedliche Sensorsignale erzeugt. Dies ist darauf zurückzuführen, daß der Stoßfänger bzw. die Dämpfungseinrichtung in bezug auf Dicke, Steifigkeit etc. über die Fahrzeugbreite variiert.When integrating sensors into the damping device via the entire vehicle width, however, there is the problem of an inhomogeneous Sensing profile, i.e. with the same impact parameters (accelerated Mass, relative impact speed) will be different Sensor signals generated. This is due to the fact that the bumper or the damping device varies in thickness, rigidity, etc. across the vehicle width.
Die Erfindung schafft eine kostengünstig realisierbare Fußgängerschutzvorrichtung, mit der ein weitgehend homogenes Sensierungsprofil erreicht werden kann.The invention creates an inexpensive to implement Pedestrian protection device with which a largely homogeneous sensation profile can be achieved can.
Gemäß der Erfindung ist bei einer Fußgängerschutzvorrichtung der eingangs genannten Art vorgesehen, daß der Sensor mit vorbestimmten, mit dem Einbauort variierenden Integrationsparametern in die Dämpfungseinrichtung integriert ist. Die Erfindung beruht auf der Erkenntnis, daß eine durch eine ungleichmäßige Steifigkeit eines Stoßfängers bedingte unterschiedliche Sensierung eines Aufpralls durch gezielte Maßnahmen bei der Integration des Sensors in die Dämpfungseinrichtung an den erforderlichen Stellen ausgeglichen werden kann. Die Erfindung schafft somit erstmals eine funktionale Integration des Sensors in den Stoßfänger, durch die ein vorher festgelegtes, spezifiziertes Ansprechverhalten ermöglicht wird. Die verschiedenen Möglichkeiten bezüglich der Variation der Integrationsparameter (z.B. die Integrationstiefe des Sensors in einem Schaum der Dämpfungseinrichtung) sind in der detaillierten Figurenbeschreibung angegeben.According to the invention is one Pedestrian protection device of the type mentioned in the introduction that the sensor with predetermined, with the installation location varying integration parameters in the damping device is integrated. The invention is based on the knowledge that a through an uneven rigidity of a bumper different sensations of an impact through targeted measures when integrating the sensor into the damping device to the required Bodies can be compensated. The invention thus creates for the first time a functional integration of the sensor into the bumper which enables a predetermined, specified response behavior. The different possibilities regarding the Variation of the integration parameters (e.g. the depth of integration of the sensor in a foam of the damping device) are in the detailed description of the figures.
Ein Vorteil der Erfindung besteht darin, daß die Fußgängerschutzvorrichtung an spezifische Anforderungen angepaßt werden kann. So können durch geeignete Wahl der Integrationsparameter beispielsweise bereits Objekte von 1 kg Masse bei einem Aufprall mit 20 km/h ein Sensorsignal auslösen. Es kann aber auch eine Abstimmung auf eine Obergrenze der Aufprallschwere vorgesehen sein, z.B. auf die aus der derzeitigen Gesetzgebung bekannten Größen von 13,4 kg und 40 km/h, aber auch auf Größen wie 100 kg Masse und 50 km/h.An advantage of the invention is in that the Pedestrian protection device can be adapted to specific requirements. So through suitable selection of the integration parameters, for example Objects of 1 kg mass in the event of an impact at 20 km / h a sensor signal trigger. It can also be adjusted to an upper limit of the severity of the impact be provided, e.g. to the sizes known from the current legislation of 13.4 kg and 40 km / h, but also on sizes such as 100 kg mass and 50 km / h.
Als Sensoren sind insbesondere kraft- bzw. druckabhängige Sensoren geeignet. Im Falle eines schalterartigen Sensors ist das Sensorsignal durch dessen Schaltschwelle bestimmt, im Falle eines analogen Sensors kann ein bestimmter Signalwert als Aufprallsignal festgelegt werden.In particular, force sensors or pressure-dependent Suitable sensors. In the case of a switch-like sensor, that is Sensor signal determined by its switching threshold, in the case of a analog sensor can have a certain signal value as an impact signal be determined.
Als stoßabsorbierendes Material wird vorzugsweise ein Schaum, insbesondere ein EPP-Schaum (Expanded-Polypropylene-Schaum) verwendet.As a shock absorbing material preferably a foam, in particular an EPP foam (expanded polypropylene foam) is used.
Bei den bevorzugten Ausführungsformen der Erfindung ist der Sensor eine Kontaktleiste, die bei einer Deformation um einen spezifischen Schaltweg ihren Schaltzustand ändert und so einen Aufprall signalisiert.In the preferred embodiments of the invention, the sensor is a contact strip, which is in the event of a deformation their switching state changes by a specific switching path and such an impact signals.
Für die folgenden Erläuterungen wird der Einfachheit halber von einem Aufbau der Fußgängerschutzvorrichtung ausgegangen, bei der die Kontaktleiste nicht in den Schaum eintaucht, und es wird nur die an die Kontaktleiste angrenzende Fläche des Schaums betrachtet.For the following explanations is for the sake of simplicity of a structure of the pedestrian protection device assumed that the contact strip is not immersed in the foam, and it just becomes the surface of the foam adjacent to the contact bar considered.
Verwendet man einen Schaum, dessen Steifigkeit wesentlich geringer als die der Kontaktleiste ist, entspricht die Ansprechschwelle unmittelbar der Schaltkraft der Kontaktleiste, d.h. der Kraft, die auf die Kontaktleiste wirken muß, damit diese ein Signal erzeugt. Im anderen Fall, wenn also die Steifigkeit des Schaums wesentlich größer als die der Kontaktleiste ist, entspricht die Ansprechschwelle der Kontaktleiste der Kraft, die notwendig ist, den Schaum um den Schaltweg der Kontaktleiste zu deformieren. Dem daraus resultierenden Zielkonflikt, bei Verwendung einer zu „steifen" Kontaktleiste Einbußen in der Leistungsfähigkeit des Schaums hinsichtlich der Energieaufnahme in Kauf nehmen zu müssen, bei Verwendung einer zu „weichen" Kontaktleiste dagegen aufgrund der stark temperaturabhängigen Steifigkeit des Schaums eine ungleichmäßige Ansprechschwelle der Kontaktleiste zu erhalten, begegnet die Erfindung mit einer Reihe von Gegenmaßnahmen, die in den Unteransprüchen angegeben sind. Diese Maßnahmen gewährleisten zum einen ein weitgehend temperaturunabhängiges Ansprechverhalten der Kontaktleiste, zum anderen sorgen sie auch für einen Ausgleich von baulichen Einflüssen auf die Ansprechschwelle der Kontaktleiste, die beispielsweise durch das räumliche Design der Stoßfängerverkleidung oder durch diverse Einbauteile bedingt sein können. Insgesamt wird somit ein gleichbleibendes Kraft/Weg-Verhalten für die Auslösung eines Schaltvorgangs der Kontaktleiste erreicht.If you use a foam whose Stiffness is significantly lower than that of the contact strip the response threshold directly of the switching force of the contact strip, i.e. the force that must act on the contact strip, so this generates a signal. Otherwise, if the rigidity of the Foam much larger than that of the contact strip corresponds to the response threshold of the contact strip the force that is needed, the foam around the switching path of the contact strip to deform. The resulting conflict of objectives when using one too "stiff" contact strip Loss in performance the foam in terms of energy consumption Use of a "soft" contact strip, however, due to the strongly temperature-dependent Stiffness of the foam an uneven response threshold of the contact strip To get the invention countered with a number of countermeasures, those in the subclaims are specified. These measures guarantee on the one hand a largely temperature-independent response behavior of the contact strip, on the other hand, they also take care of a compensation of structural influences on the response threshold the contact bar, for example, by the spatial Design of the bumper cover or may be due to various built-in parts. So overall a constant force / displacement behavior for triggering a switching process Contact bar reached.
