Darüber hinaus wurden beispielsweise auf dem Kongress ”Schutz der Fußgänger bei Kollisionen mit PKW” vom 20.–21.6.2001 in München, veranstaltet vom Haus der Technik e. V. Essen von prof. Dr.-Ing. habil. Gustav Kasanicky und Prof. Dipl. Ing. Dr. techn. Hermann Steffan ”Der Einfluss des Fahrzeug-Frontgestaltung auf die Bewegung des Fußgängers beim Pkw-Frontalaufprall” Programme vorgestellt, mit denen anhand von Parametern eines Objektes der Zusammenstoß und nachfolgende Aufprall auf die Fahrbahn simuliert werden kann.Furthermore were, for example, at the Congress "Protection of pedestrians at Collisions with cars "vom 20.-21.6.2001 in Munich, organized by the House of Technology e. V. Food of prof. Dr.-Ing. habil. Gustav Kasanicky and Prof. Dipl. Ing. techn. Hermann Steffan "The Influence of the vehicle front design on the movement of the pedestrian Car Frontal Impact "programs presented with the help of parameters of an object of the Collision and subsequent impact on the roadway can be simulated.
Aufgabe der Erfindung ist es, den Schutz lebender Objekte bei einem Zusammenstoß mit einem Fahrzeug weiter zu verbessern.task The invention is the protection of living objects in a collision with a vehicle continue to improve.
Dazu wird vorgeschlagen, mittels Sensoren am Fahrzeug einerseits Parameter über die Bewegung des Fahrzeugs und/oder die Relativbewegung zum Objekt sowie andererseits Parameter von Objekten im Nahbereich des Fahrzeugs zu erfassen, aus diesen Parametern die Art des Zusammenstosses und die zu erwartende Art des nachfolgenden Auftreffens des Objektes auf der Fahrbahn abzuleiten und am Fahrzeug vorgesehene Schutzmittel in Abhängigkeit der zu erwartenden Art des Auftreffens des Objektes auf der Fahrbahn zu steuern.To is suggested by means of sensors on the one hand, parameters on the Movement of the vehicle and / or the relative movement to the object as well on the other hand, parameters of objects in the vicinity of the vehicle to record from these parameters the nature of the collision and the expected type of subsequent impact of the object derive on the road and provided on the vehicle protection dependent on the expected type of impact of the object on the roadway to control.
Grundgedanke dieser Erfindung ist also, die vorhandenen Schutzmittel nicht nur hinsichtlich des Primäraufpralls des Objektes auf das Fahrzeug auszurichten, sondern zumindest auch ergänzend den dabei zu erwartenden Sekundäraufprall des Objektes auf die Fahrbahn zu berücksichtigen. Dabei hängt die Art des zu erwartenden Sekundäraufpralls des Objektes auf die Fahrbahn maßgeblich von den besonderen Eigenschaften des Objektes, insbesondere der Lage des Schwerpunkts und Schwerpunktverteilung maßgeblich ab und ist bei den verschiedenen typischen Unfallopfern bei Zusammenstößen mit Fahrzeugen stark unterschiedlich. Daher sollen insbesondere Parameter von Objekten im Nahbereich des Fahrzeugs erfasst werden, die für dieses unterschiedliche Verhalten während des Primär- und Sekundäraufpralls entscheidend sind. Insbesondere wird geprüft, ob das Objekt im Nahbereich einen Kopf aufweist und dessen Position erfasst. Gerade die Kopfposition ist bei Zusammenstößen mit kleineren lebenden Objekten, insbesondere Kindern, äußerst entscheidend und kann eine entsprechend angepasste Auslösung der Schutzmittel ermöglichen. Durch die Erfassung eines Bildes des Objektes im Nahbereich können weitere Aussagen über das Objekt gemacht werden und entsprechend über einen Mustervergleich zugeordnete Parameter für die Bewertung der Art des Zusammenstoßes und die zu erwartende Art des nachfolgenden Auftreffens des Objektes auf der Fahrbahn abgeleitet werden. So können geeignete Maßnahmen, beispielsweise für einen Zusammenstoß nicht nur mit einem Fußgänger normaler Größe, sondern auch bei einem Zusammenstoß mit einem Kind, einem Radfahrer, einem Motorradfahrer, einem Kinderwagen und diversen Tieren mit unterschiedlich Gewichtsklassen, unterschieden und entsprechende angepasste Steuerungen für die Schutzmittel vorgesehen werden.The basic idea of this invention is thus to align the existing protection means not only with regard to the primary impact of the object on the vehicle, but at least also to take into account the expected secondary impact of the object on the roadway. The type of expected secondary impact of the object on the roadway is significantly dependent on the particular properties of the object, in particular the position of the center of gravity and center of gravity distribution and is greatly different in the various typical accident victims in collisions with vehicles. Therefore, in particular parameters of objects in the vicinity of the vehicle are to be detected, which are crucial for this different behavior during the primary and secondary impact. In particular, it is checked whether the object has a head in the vicinity and detects its position. Especially the head position is in clashes with smaller living objects, especially children, extremely crucial and can allow a correspondingly adapted triggering the protection. By capturing an image of the object in the near range, further statements about the object can be made and corresponding parameters for evaluating the type of collision and the expected type of subsequent impact of the object on the roadway can be derived via a pattern comparison. Thus, suitable measures, for example, for a collision not only with a pedestrian normal size, but also in a collision with a child, a cyclist, a motorcyclist, a stroller and various animals with different weight classes, distinguished and appropriate controls for the Protective means are provided.
Aufgrund der Vielzahl möglicher Schutzmittel wird hierbei nicht individuell auf die jeweils für das konkrete Objekt geeignete Steuerungsmaßnahme eingegangen, wobei eine Vielzahl von Schutzmitteln, insbesondere die Neigung der Fahrzeugfront und/oder der Motorhaube und/oder des Gesamtfahrzeuges betrifft und diese Neigung in Abhängigkeit der zu erwartenden Art des Auftreffens des Objektes zunächst auf das Fahrzeug und damit aber auch auf die Fahrbahn gezielt gesteuert wird. Dabei soll insbesondere der Auftreffwinkel des Objektes auf die Fahrbahn verringert und vermieden werden, dass das Objekt mit dem Kopf direkt auf die Fahrbahn auftrifft.by virtue of the variety of possible Protection is not individualized to the particular for the specific Object received appropriate control measure, being a plurality of protection means, in particular the inclination the vehicle front and / or the hood and / or the entire vehicle affects and this inclination depending on the expected Type of impact of the object first on the vehicle and thus but also targeted to the roadway. It should in particular reduces the impact angle of the object on the road and Avoid the object with your head directly on the roadway incident.
