Der Erfindung liegt nun die Aufgabe zugrunde, eine Aufprallerfassungseinrichtung für ein Kraftfahrzeug mit wenigstens einem in seinem Frontbereich angeordneten mit einem Medium gefüllten Hohlkörper anzugeben, welche eine gegenüber dem Stand der Technik zuverlässigere Erkennung eines auf das Kraftfahrzeug prallenden Objekts gewährleistet.Of the The invention is based on the object, an impact detection device for a Motor vehicle with at least one arranged in its front area indicate hollow body filled with a medium, which one opposite the prior art more reliable Detection of a bouncing on the vehicle object guaranteed.
Die genannte Aufgabe wird gelöst durch eine Aufprallerfassungseinrichtung für ein Kraftfahrzeug mit wenigstens einem in seinem Frontbereich angeordneten mit einem Medium gefüllten Hohlkörper mit den Merkmalen des Patentanspruches 1.The this task is solved by an impact detection device for a motor vehicle with at least arranged in its front region filled with a medium hollow body with the Features of claim 1.
Erfindungsgemäß ist der weitere Drucksensor in einem vorgegebenen Abstand zu dem ersten Drucksensor im Bereich des Hohlkörpers angeordnet, wobei aus Laufzeitunterschieden für die erfassten Drucksignale der Druckwelle zwischen den beiden Drucksensoren auf den Aufprallort geschlossen wird. Die Aufprallerfassungseinrichtung für ein Kraftfahrzeug umfasst wenigstens einen in seinem Frontbereich angeordneten und mit einem Medium gefüllten Hohlkörper, in welchem in Folge einer auf den Hohlkörper ausgeübten äußeren Kraft eine Druckwelle erzeugbar ist. In einem Bereich des Hohlkörpers ist ein Drucksensor zur messtechnischen Erfassung der Druckwelle angeordnet. Mit der erfindungsgemäßen Aufprallerfassungseinrichtung ist ein individualisierter Schutz für Personen im nahen Umgebungsbereich des Kraftfahrzeuges, insbesondere für Fußgänger, und für Personen im Kraftfahrzeug gegeben. Da die Größe der beim Aufprall im Hohlkörper erzeugten Druckwelle von der Masse und der Geschwindigkeit des aufprallenden Objekts abhängt und die Eigengeschwindigkeit des Kraftfahrzeuges zu jedem Zeitpunkt bekannt ist, kann auf die Masse des aufprallenden Objekts geschlossen werden. Die Aufprallerfassungseinrichtung kann somit zwischen einem Fußgänger und anderen in Frage kommenden Objekten unterscheiden und situationsbedingt geeignete fahrzeugseitige Sicherheitsmaßnahmen einleiten. Eine unnötige Auslösung von Sicherheitseinrichtungen für den Fußgängerschutz durch kleinere und leichtere Objekte im Vergleich zu einem Fußgänger kann dadurch verhindert werden. Die Aufprallerfassungseinrichtung erweist sich als unempfindlich gegenüber mechanischen Verspannungen im Bereich der Drucksensoren, so dass langsam erfolgende Deformationen, beispielsweise bei einem Einparkvorgang des Kraftfahrzeuges, weitestgehend nicht von der Aufprallerfassungseinrichtung erfasst werden. Des weiteren erzeugen Bewegungen mit einer nur geringen Auslenkung der Kraftfahrzeugkarosserie im Frontbereich, beispielsweise verursacht durch Vibrationen auf einer Schlechtwegstrecke, im Drucksensor nur Signale mit einer geringen Intensität oder gar keine Signale. Als Medium für den Hohlkörper sind ein Gas, eine Flüssigkeit oder ein Gel vorgesehen.According to the invention, the further pressure sensor is arranged at a predetermined distance from the first pressure sensor in the region of the hollow body, wherein the pressure wave between the two pressure sensors is closed at run-off for runtime differences for the detected pressure signals. The impact detection device for a motor vehicle comprises at least one hollow body arranged in its front region and filled with a medium, in which a pressure wave can be generated as a result of an external force exerted on the hollow body. In a region of the hollow body, a pressure sensor for metrological detection of the pressure wave is arranged. The impact detection device according to the invention provides individualized protection for persons in the immediate vicinity of the motor vehicle, in particular for pedestrians, and for persons in the motor vehicle. Since the magnitude of the pressure wave generated during impact in the hollow body depends on the mass and speed of the impacting object and the intrinsic speed of the motor vehicle is known at all times, the mass of the impacting object can be deduced. The impact detection device can thus differentiate between a pedestrian and other objects in question and, depending on the situation, initiate suitable vehicle-side safety measures. An unnecessary triggering of safety devices for pedestrian protection by smaller and lighter objects compared to a pedestrian can be prevented. The impact detection device proves to be insensitive to mechanical tension in the area of the pressure sensors, so that deformations that occur slowly, for example during a parking operation of the motor vehicle, are largely not detected by the impact detection device. Furthermore, movements generate only a slight deflection of the vehicle body in the front area, for example caused by Vibra tions on a poor road, in the pressure sensor only signals with a low intensity or no signals. As a medium for the hollow body, a gas, a liquid or a gel are provided.
In einer Ausgestaltung der Erfindung ist der Hohlkörper als elastischer Schlauch ausgebildet, wobei der Hohlkörper auch mehrere Schläuche umfassen kann. Dabei ist vorgesehen, dass der elastische Schlauch an seinen beiden Enden jeweils mit einem Drucksensor versehen ist. Der elastische Schlauch ist für einen Einbau ins Kraftfahrzeug besonders günstig geeignet und mit einem nur geringen Aufwand zu Bewerkstelligen. Zudem kann durch geeignete Wahl seiner Länge und seiner geometrischen Anordnung ein großer Bereich des Kraftfahrzeuges sensortechnisch erfasst werden. Der Einsatz des Schlauches ist auch für seitliche und hintere Bereiche des Kraftfahrzeuges geeignet.In An embodiment of the invention is the hollow body as an elastic hose formed, wherein the hollow body also several hoses may include. It is envisaged that the elastic hose is provided at its two ends in each case with a pressure sensor. The elastic hose is for an installation in the motor vehicle particularly favorable and with a only little effort to accomplish. In addition, by suitable Choice of his length and its geometric arrangement, a large area of the motor vehicle sensor technology be recorded. The use of the hose is also for lateral and rear portions of the motor vehicle suitable.
In einer weiteren Ausgestaltung ist als Drucksensor ein piezoelektrischer Sensor vorgesehen. Der Einsatz eines piezoelektrischen Sensors in der Aufprallerfassungseinrichtung erweist sich im Einsatz als besonders zuverlässig und störunanfällig. Der von den Druckwellen ausgeübte Druck wird in ein elektrisches Spannungssignal umgewandelt.In a further embodiment is a piezoelectric as a pressure sensor Sensor provided. The use of a piezoelectric sensor in the impact detection device proves to be particularly in use reliable and susceptible to interference. The of the pressure waves exerted Pressure is converted into an electrical voltage signal.
