Abstract
Description
Die Erfindung betrifft ein Schutzsystem für Verkehrsteilnehmer nach dem Oberbegriff des Anspruchs 1. Schutzsysteme für Fahrzeuginsassen, wie insbesondere Gurtstraffer und Airbags, sind heute Serienstandard und werden praktisch für alle Fahrzeugklassen angeboten. Sie bieten einen optimalen Schutz für Fahrzeuginsassen und haben wesentlich dazu beigetragen, dass die Zahl der Unfallopfer zurückgegangen ist. Für einen verbesserten Schutz der schwächsten Verkehrsteilnehmer, der Fußgänger, wurde bisher vergleichsweise wenig erreicht. Es sind daher bereits gesetzgeberische Aktivitäten ins Auge gefasst, die eine Verbesserung der Schutzmöglichkeiten für Fußgänger durch gesetzliche Vorschriften zum Ziel haben. Zusätzlich haben sich die Fahrzeughersteller freiwillig verpflichtet, den Fußgängerschutz durch eine bessere Konstruktion der Fahrzeuge zu verbessern. So soll eine Verbesserung beispielsweise durch an Fußgänger angepasste Sensoren und Aktoren erreicht werden. Im Bereich der Sensoren sind vorwiegend Kontaktsensoren vorgesehen, die in der Stossstange angeordnet sind. Diese Kontaktsensoren, die sich vorzugsweise über die gesamte Breite der Stossstange erstrecken, basieren auf einer Kraftmessung oder einer Verformung. Beispiele für solche Kraftsensoren sind Piezofolien, Dehnmessstreifen, Lichtsensoren oder Sensoren aus einem Kompositwerkstoff. Bei Verformungssensoren werden ebenfalls Lichtleiter oder einfache Kontaktschalter eingesetzt. Im Weiteren besteht die Möglichkeit, direkt an der sog. Crash-Box, verschiedene, die Beschleunigung oder Kräfte messende Sensoren anzubringen.The The invention relates to a protection system for road users after The preamble of claim 1. Protection systems for vehicle occupants, in particular Belt tensioners and airbags are standard today and become practical for all Vehicle classes offered. They offer optimal protection for vehicle occupants and have significantly contributed to the number of accident victims declined is. For improved protection of the weakest road users, the pedestrian, became so far comparatively little achieved. It is therefore already legislative activities envisaged an improvement of the protection possibilities for pedestrians statutory provisions. In addition, the vehicle manufacturers have voluntarily committed to pedestrian protection by to improve a better construction of the vehicles. So should one Improvement, for example, by sensors and actuators adapted to pedestrians be achieved. In the field of sensors are mainly contact sensors provided, which are arranged in the bumper. These contact sensors, preferably over extend the entire width of the bumper, are based on a Force measurement or deformation. Examples of such force sensors are Piezo films, strain gauges, light sensors or sensors from one Composite. Deformation sensors also become light guides or simple contact switch used. Furthermore, there is the Possibility, directly at the so-called crash box, different, the acceleration or personnel to install measuring sensors.
Im Weiteren sind auch vorausschauende Sensoren, sogenannte Precrashsensoren, eingeplant, wie z.B. Video- oder Radarsensoren, die einen Fußgänger über eine Bildauswertung oder anhand der reflektieren Signale erkennen sollen.in the Further are also forward-looking sensors, so-called precrash sensors, scheduled, such as Video or radar sensors that move a pedestrian across a Image evaluation or based on the reflected signals to recognize.
Als Schutzmittel für den Fußgänger können im Wesentlichen Airbagsysteme in den Rahmen der Windschutzscheibe bzw. in den Motorraum des Fahrzeugs integriert werden. Oder aber die Motorhaube des Fahrzeugs kann angehoben werden, um den Aufprall eines Fußgängers abzumildern. Ein Nachteil der bisher vorgeschlagenen Konzepte ist, dass keine Vorhersage über den Auftreffzeitpunkt und die Auftreffstelle besonders gefährdeter Körperteile des Fußgängers, insbesondere des Kopfes, auf die Motorhaube oder die Windschutzscheibe des Fahrzeugs gemacht werden kann.When Protective agent for the pedestrian can walk in Essential airbag systems in the frame of the windshield or be integrated into the engine compartment of the vehicle. Or the Bonnet of the vehicle can be raised to the impact to mitigate a pedestrian. A disadvantage of the concepts proposed so far is that no prediction about the Time of impact and the point of impact of the most vulnerable Body Parts of the pedestrian, in particular of the head, on the bonnet or the windshield of the vehicle can be made.
Vorteile der ErfindungAdvantages of the invention
Ein Schutzsystem mit den Merkmalen des Anspruchs 1 ermöglicht es insbesondere, die Auslösung der Schutzmittel für den Fußgänger zu verbessern, indem die Zeit und/oder der Ort des Kopfaufpralls vorhergesagt werden. Wenn die ungefähre Aufprallzeit und der eventuelle Aufprallort hinreichend genau bekannt wären, können ggf. vorhandene Schutzmittel wesentlich wirksamer eingesetzt werden. Insbesondere kann auch die Schutzwirkung an Fußgänger unterschiedlicher Größe besser angepasst werden, da vorhandene Schutzmittel für erwachsene Personen und Kinder in unterschiedlicher Weise eingesetzt werden. Da es sich bei den allermeisten schweren Verletzungen der Fußgänger um Kopfverletzungen handelt, kann durch eine optimierte Auslösung der Schutzmittel in vielen Fällen eine schwere Verletzung vermieden werden. Die Erfindung geht dabei also von der Erkenntnis aus, dass neben anderen Parametern, die Größe eines Fußgängers von besonderer Bedeutung für den Einsatz der Schutzmittel ist. Mittels einer vorausschauenden Sensorik wird daher die Größe eines gefährdeten Fußgängers erfasst. Aus diesem erfassten Größenwert werden dann Aufprallzeitpunkt und Aufprallort ermittelt. Mit Hilfe der so ermittelten Werte für Aufprallzeitpunkt und Aufprallort werden dann die Schutzmittel für den gefährdeten Fußgänger optimal gesteuert.One Protection system with the features of claim 1 makes it possible in particular, the triggering the protective agent for the pedestrian too Improve by predicting the time and / or location of the head impact become. When the approximate impact time and the eventual location of impact would be known with sufficient accuracy, existing protective agents are used much more effectively. In particular, the protective effect on pedestrians of different sizes can be better be adapted, since existing protection means for adults and children be used in different ways. Since it is at the most serious injuries pedestrian involves head injuries, can by optimized triggering the protective agent in many cases a serious injury can be avoided. The invention goes thereby So from the knowledge that, among other parameters, the Size of one Pedestrian of of special importance for the use of the protective agent is. By means of a forward-looking sensor is therefore the size of a endangered pedestrian. From this recorded size value then the impact time and impact location are determined. With help the values thus determined for Impact time and place of impact then become the means of protection for the endangered Pedestrian optimally controlled.
