Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Sicherheitsvorrichtung eines Fahrzeugs, wobei die Sicherheitsvorrichtung vor und/oder während einer Kollision des Fahrzeugs mit einem Hindernis aktiviert wird, wobei zumindest eine Fußgängerschutzvorrichtung der Sicherheitsvorrichtung dann aktiviert wird, wenn als Hindernis ein Fußgänger erkannt wird.The invention relates to a method for operating a safety device of a vehicle, wherein the safety device is activated before and / or during a collision of the vehicle with an obstacle, wherein at least one pedestrian protection device of the safety device is activated when a pedestrian is detected as an obstacle.
Die Erfindung betrifft weiterhin eine Vorrichtung zum Betrieb einer Sicherheitsvorrichtung eines Fahrzeugs, wobei die Sicherheitsvorrichtung eine Steuereinheit zur Aktivierung der Sicherheitsvorrichtung vor und/oder während einer Kollision des Fahrzeugs mit einem Hindernis und eine Fußgängerschutzvorrichtung umfasst, welche aktivierbar ist, wenn aus Daten zumindest einer Erfassungseinheit als Hindernis ein Fußgänger erkennbar ist.The invention further relates to a device for operating a safety device of a vehicle, wherein the safety device comprises a control unit for activating the safety device before and / or during a collision of the vehicle with an obstacle and a pedestrian protection device which can be activated, if from data of at least one detection unit as Obstacle a pedestrian is recognizable.
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zum Betrieb einer Sicherheitsvorrichtung eines Fahrzeugs und eine Vorrichtung zum Betrieb einer Sicherheitsvorrichtung eines Fahrzeugs anzugeben.The invention is based on the object to provide a comparison with the prior art improved method for operating a safety device of a vehicle and an apparatus for operating a safety device of a vehicle.
Hinsichtlich des Verfahrens wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich der Vorrichtung durch die im Anspruch 6 angegebenen Merkmale gelöst.With regard to the method, the object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
In einem Verfahren zum Betrieb einer Sicherheitsvorrichtung eines Fahrzeugs wird die Sicherheitsvorrichtung vor und/oder während einer Kollision des Fahrzeugs mit einem Hindernis aktiviert, wobei zumindest eine Fußgängerschutzvorrichtung der Sicherheitsvorrichtung dann aktiviert wird, wenn als Hindernis ein Fußgänger erkannt wird. Erfindungsgemäß wird die Erkennung des Hindernisses in einem Bildverarbeitungsverfahren aus mittels zumindest einer Bilderfassungseinheit erfassten Bildern einer Umgebung des Fahrzeugs durchgeführt.In a method for operating a safety device of a vehicle, the safety device is activated before and / or during a collision of the vehicle with an obstacle, wherein at least one pedestrian protection device of the safety device is activated when a pedestrian is detected as an obstacle. According to the invention, the recognition of the obstacle in an image processing method is performed from images of surroundings of the vehicle acquired by means of at least one image acquisition unit.
Aus dem erfindungsgemäßen Verfahren resultiert in besonders vorteilhafter Weise die Möglichkeit einer sehr frühzeitigen und zuverlässigen Erkennung der Hindernisse, so dass eine eindeutige und zuverlässige Unterscheidung zwischen einer bevorstehenden Kollision mit einem Fußgänger und Kollisionen mit Tieren, beweglichen oder unbeweglichen Gegenständen möglich ist. Wird als Hindernis ein Fußgänger erkannt, kann daraus folgend aufgrund einer sehr kurzen Plausibilisierungszeit bei der Erkennung des Hindernisses als Fußgänger eine besonders frühzeitige Auslösung der Fußgängerschutzvorrichtung durchgeführt werden, so dass ein besonders hoher Schutz des Fußgängers realisierbar ist. Weiterhin resultiert aus der eindeutigen und zuverlässigen Unterscheidung der Vorteil, dass Fehlauslösungen der Fußgängerschutzvorrichtung im Fall von bevorstehenden Kollisionen mit Tieren, beweglichen oder unbeweglichen Gegenständen minimiert werden. Deshalb ist die Anzahl der Fälle, in welchen ein Rückstellen und Wiederherstellen der reversibel oder irreversibel ausgebildeten Fußgängerschutzvorrichtung erforderlich ist, verringert. Daraus folgend werden Kosten zur Wiederherstellung der ausgelösten Fußgängerschutzvorrichtung, insbesondere Garantie- und Kulanzkosten, minimiert.From the method according to the invention results in a particularly advantageous way the possibility of a very early and reliable detection of obstacles, so that a clear and reliable distinction between an imminent collision with a pedestrian and collisions with animals, movable or immovable objects is possible. If a pedestrian is recognized as an obstacle, a particularly early triggering of the pedestrian protection device can be carried out as a result of a very short plausibility time in recognizing the obstacle as a pedestrian, so that a particularly high degree of pedestrian protection can be achieved. Furthermore, the clear and reliable distinction results in the advantage that false triggering of the pedestrian protection device is minimized in the case of impending collisions with animals, moving or immovable objects. Therefore, the number of cases where resetting and restoring the reversibly or irreversibly formed pedestrian protection device is required is reduced. As a result, costs for restoring the triggered pedestrian protection device, in particular warranty and goodwill costs, are minimized.

Die Sicherheitsvorrichtung
Des Weiteren ist durch die angehobene Fronthaube ein erhöhter Freiraum zwischen der Fronthaube und einem Motor des Fahrzeugs
Zusätzlich ist die Fronthaube nicht nur anhebbar, sondern auch in Richtung der Frontscheibe verschiebbar und dadurch über unteren Teilbereichen der Frontscheibe und angrenzenden Bereichen der Fahrzeugkarosserie positionierbar.In addition, the front hood is not only liftable, but also displaced in the direction of the windshield and thereby positioned over lower portions of the windscreen and adjacent areas of the vehicle body.
In nicht näher dargestellter Weise umfasst die Fußgängerschutzvorrichtung
Alternativ oder zusätzlich zu dem Airbag umfasst die Fußgängerschutzvorrichtung
Weiterhin wird bei als Fußgänger F erkanntem Hindernis H automatisch und situationsabhängig, d. h. insbesondere in Abhängigkeit von einer Beschaffenheit der Fahrbahn, einer Geschwindigkeit des Fahrzeugs, einer Relativgeschwindigkeit und einer Position des Fußgängers F, eine Teilbremsung oder Vollbremsung in einer von dem Fahrzeug
