Anordnung zur Erfassung eines Zusammensto- Arrangement for detecting a collision
13es eines Fahrzeugs mit einem Fußgänger Die Erfindung bezieht sich auf eine Anordnung zur Erfassung eines Zusammenstoßes eines Fahrzeugs, insbesondere Personenkraftfahrzeugs, mit einem Fußgänger unter Verwendung einer im Bereich einer Frontstoßstange angeordneten ersten Sensorleiste. 13es of a vehicle with a pedestrian The invention relates to an arrangement for detecting a collision of a vehicle, in particular Passenger vehicle, with a pedestrian using one in the area of a Front bumper arranged first sensor strip.
Es sind bereits eine Reihe von im Bereich der Fronthaube von Fahrzeugen, insbesondere von Personenkraftfahrzeugen, angeordneten Vorrichtungen zum Schutz von mit dem Fahrzeug kollidierenden Fußgängern vorgeschlagen worden (zum Beispiel DE-OS 26 13 748), die das sehr hohe Verletzungsrisiko für die in solche Zusammenstöße verwickelten Fußgänger herabsetzen sollen. Die Signale zur Auslösung dieser Schutz-oder Auffangvorrichtungen, das heißt zur Uberführung dieser Vorrichtungen aus ihrer Ruhestellung in ihre Rückhaltestellung, kommen dabei im allgemeinen von dem Zusammenstoß erfassenden sogenannten Kollisionssensoren, die üblicherweise in Form von Sensorleisten im Bereich der Frontstoßstange des Fahrzeugs angeordnet sind.There are already a number of in the area of the front hood of vehicles, in particular of passenger vehicles, arranged devices for protection suggested by pedestrians colliding with the vehicle (for example DE-OS 26 13 748), which has the very high risk of injury for those involved in such collisions should belittle entangled pedestrians. The signals to trigger this protection or Catching devices, that is, to move these devices out of their rest position in their restraint position, generally come from the collision detectors so-called collision sensors, which are usually in the form of sensor strips in the area the front bumper of the vehicle are arranged.
Solche in der Frontstoßstange angeordneten Sensorleisten können jdoch auch beim Berühren niedriger Hindernisse, wie Begrenzungspfählen und dergleichen,insbesondere bei Parkmanövern,betätigt werden und würden dann unnötigerweise die Fußgängerschutzvorrichtung auslösen.Such sensor strips arranged in the front bumper can jdoch even when touching low obstacles, such as boundary posts and the like, in particular during parking maneuvers, and would then unnecessarily the pedestrian protection device trigger.
Die der Erfindung zugrundeliegende Aufgabe besteht daher darin, ein.The object on which the invention is based is therefore to provide a.
Sensoranordnung zu schaffen, die ohne großen Aufwand eine gute flL.To create a sensor arrangement that produces a good flow rate without great effort.
cherheit gegen solche falschen Auslösungen der Fußgängerschutzvorrichtungen schafft.security against such false tripping of the pedestrian protection devices creates.
Zur Lösung dieser Aufgabe wird von der Erfindung vorgeschlagen, daß eine zweite Sensorleiste im Bereich der Vorderkante der Fahrzeugfronthaube angebracht ist und daß eine den beiden Sensorleisten nachgeschaltete Auswerteinrichtung vorgesehen ist, die ein Signal zuis £un.To solve this problem, the invention proposes that a second sensor strip is attached in the area of the front edge of the vehicle front hood and that an evaluation device connected downstream of the two sensor strips is provided is giving a signal tois £ un.
lösen einer Vorrichtung zum Schutz des Fußgängers erst bei Vorliegen der Signale beider Sensorleisten abgibt. Dadurch, daß gemäß der 3 findung die Signale beider Sensorleisten, die an unterschiediict-Stellen des Fahrzeugs, nämlich im Bereich der vorderen Stoß9t8ag und der Vorderkante der Fahrzeugfronthaube, angeordnet sind, zur Auslösung der Fußgängerschutzvorrichtung herangezogen werden, wird eine große Sicherheit gegen Falschauslösungen erreicht. Wenn das Pahtscug nämlich, beispielsweise bei Parkmanövern,mit anderen Fahrzeugen oder mit niedrigen Hindernissen,wie Begrenzungspfählen oder dergleichen, zusammenstößt, wird nämlich nur die an der Stoßstange angeordnote Sensorleiste betätigt, was jedoch noch nicht zur Auslösung der FUB-gängerschutzvorrichtung fUhrt, die in ihrem ausgelösten Zustand den Fahrzeugführer am sicheren Fuhren des Fahrzeugs hindern könnte. Die Auswerteinrichtung könnte zudem so ausgelegt sein, daß sie das Auslösesignal erst dann weitergibt, wenn auch eine bestimmte Folge der von den Sensorleisten kommenden Signale eingehalten wird. Bei einem Zusammenstoß mit einem Fußgänger wird nämlich normalerweise zuerst die in der Stoßstange angeordnete Sensorleiste und danach mit einiger zeitlicher Verzögerung die in der Vorderkante der Fahrzeugfronthaube angebrachte Sensorleiste betätigt. Auch diese richtige Signal folge kann als Bedingung für die Weitergabe des Auslösesignals von der Ausweiteinriehtung festgelegt sein.solve a device for the protection of pedestrians only when present which emits signals from both sensor strips. Characterized in that, according to FIG. 3, the signals both sensor strips, which are at different points of the vehicle, namely in the area the front bumper 9t8ag and the front edge of the vehicle front hood are arranged, are used to trigger the pedestrian protection device, a large Security against false tripping achieved. If the Pahtscug namely, for example during parking maneuvers, with other vehicles or with low obstacles such as boundary posts or the like, collides, namely only the angeordnote on the bumper Sensor strip actuated, but this does not yet trigger the FUB common protection device which, in its triggered state, guides the vehicle driver in the safe driving of the Could prevent the vehicle. The evaluation device could also be designed so that it only passes on the trigger signal, even if a certain consequence of the signals coming from the sensor strips are observed. In a collision with a pedestrian, the one in the bumper is normally used first Sensor bar and then, with some delay, the one in the front edge The sensor strip attached to the front hood is actuated. Also this correct signal can follow as a condition for the forwarding of the trigger signal from the expansion device be fixed.
In der Zeichnung ist anhand einer Seitenansicht eines Vorderteils eines mit einem Fußgänger kollidierenden Kraftfahrzeugs ein Ausführungsbeispiel der Erfindung näher erläutert. Dabei ist mit 1 das Kraftfahrzeug und mit2 der Fußgänger bezeichnet, der mit dem Frihrzeug kollidiert. An der Front des Fahrzeugs sind in einer Stoßstange i2 eine erste Sensorleiste 3 und an der Vorderkante der Fahrzeughaube 11 eine zweite Sensorleiste 4 angeordnet, die über Signalleitungen 6 und 7 mit einer Auswerteinrichtung 5 verbunden sind. Diese Auswerteinrichtung 5,die die von den Sensorleisten 3, 4 kommenden Signale auswertet,gibt ein Auslösesignal über eine Signalleitung 8 an eine in dem Ausführungsbeispiel durch einen von einem Gasgenerator 9 aufblasbaren Gassack 10 gebildete Fußgängerschutzvorrichtung weiter, wenn die Signalleisten 3, 4 beim Aufprall mit dem Fußgänger betätigt sind. Die Bedingung zur Weitergabe des Auslösesignals an die Gassackvorrichtung 9, 10 kann noch insofern erweitert werden, als die Auslösung nur dann möglich ist, wenn auch eine bestimmte Signalfolge eingehalten wird, gemäß der zuerst das Signal von der in der Stoßstange 12 angeordneten Signalleiste und danach das Signal von der in der Haubenvorderkante angeordneten Signalleiste 4 bei der Auswerteinrichtung 5 eingeht.The drawing shows a side view of a front part an embodiment of a motor vehicle colliding with a pedestrian the invention explained in more detail. 1 is the motor vehicle and 2 is the pedestrian marked, which collides with the Frihrzeug. At the front of the vehicle are in a bumper i2 a first sensor strip 3 and on the front edge of the vehicle hood 11 a second sensor strip 4 is arranged, which via signal lines 6 and 7 with a Evaluation device 5 are connected. This evaluation device 5, the of the Sensor strips 3, 4 evaluates incoming signals, gives a trigger signal via a Signal line 8 to one in the exemplary embodiment through one of a gas generator 9 inflatable gas bag 10 formed pedestrian protection device continues when the Signal strips 3, 4 are actuated in the event of a collision with the pedestrian. The condition for forwarding the trigger signal to the airbag device 9, 10 can still insofar can be extended than the triggering is only possible if also a certain one Signal sequence is observed, according to which first the signal from the in the bumper 12 arranged signal strip and then the signal from the in the front edge of the hood arranged signal strip 4 in the evaluation device 5 is received.
Nach dem Auslösen der Schutzvorrichtung spannt sich bei dem in der Zeichnung gezeigten Ausführungsbeispiel ein mit strichpunktierten Linien angedeuteter Gassack 10 oberhalb der Fronthaube 11 des Fahrzeugs und vor dessen Frontscheibe in einem Gebiet auf, auf dem der Oberkörper und insbesondere der Kopf des von dem Fahrzeug angefahrenen Fußgängers aufschlagen würde und verhindert so schwerere Verletzungen des Fußgängers.After the protective device has tripped, the in the The embodiment shown in the drawing is indicated by dash-dotted lines Gas bag 10 above the front hood 11 of the vehicle and in front of its windshield in an area on which the upper body and especially the head of the of the Vehicle hit by pedestrians, thus preventing serious injuries of the pedestrian.
Die beschriebene Sensoranordnung ist aber selbstverständlich auch unabhängig von der hier gezeigten Fußgängerschutzvorrichtung für andere an einem Fahrzeug angebrachte Fußgängerschutzvorrichtungen verwendbar, die beim Zusammenprall des Fahrzeugs mit einem Fußgänger aus ihrer üblicherweise in einer meist unsichtbaren Ruhestellung in eine Rückhaltestellung überführt werden müssen.The described sensor arrangement is of course also regardless of the pedestrian protection device shown here for others on one Vehicle-mounted pedestrian protection devices can be used in the event of a collision of the vehicle with a pedestrian from their usually in a mostly invisible Rest position must be transferred to a restraint position.
