Abstract:
Die Erfindung betrifft ein Verfahren zum Ermitteln von Steuerdaten für die Auslösung von Aufprallschutzmitteln in einem Fahrzeug, bei dem vor einem Crash mit einem Verkehrsteilnehmer das Fahrzeug Crash-Identifikations-Daten von einer Signaleinrichtung des Verkehrteilnehmers empfängt und daraus Steuerdaten für die Auslösung seiner Aufprallschutzmittel ableitet. Es wird vorgeschlagen, dass die Crash-Identifikations-Daten von mindestens einer Licht emittierenden Diode (LED) des Verkehrsteilnehmers abgeben werden. Insbesondere können Fahrzeugleuchten wie Brems- und Rücklichter, oder Scheinwerfer zur Übertragung der Crash-ID genutzt werden.
Abstract:
An airbag deployment sensor has a cartridge containing a quantity of tape (36) one end of which is attached to the inside surface (18) of an airbag (13). Deployment of the airbag pulls tape (36) from the cartridge at a rate that is monitored by detecting the presence of metalized, or magnetic shielding portions, of the tape.
Abstract:
The invention relates to a starting device for a crew protecting system, which starts a plurality of crew protecting means provided on a vehicle. The starting device comprises a circuit (6) connecting a plurality of squibs (4, 5) on the crew protecting means to one another in series, a starting power supply (3) common to the series-connected circuit (6), and collision detection means (7) for detecting any possible collision to supply electric current from the starting power supply (3) to the series-connected circuit (6), all of the squibs (4, 5) in the series-connected circuit (6) being the same standard. The squibs (4, 5) of the same standard are such that degree of contact between bridge lines (42) and igniters (43) is controlled in such a manner that resistance values of the bridge lines (42) in contact with the igniter are within a predetermined range and voltage rise produced within a predetermined period of time as measured by the supply of minute electric current to the bridge lines (42) is within a predetermined range. Electric current is supplied to the series-connected circuit (6) to fuse the bridge line of at least one squib and an igniting action of all the squibs (4, 5) is started by energy which has been supplied to the respective squibs up to the fusing.
Abstract:
In a vehicle bumper structure, an optical fiber sensor (32) is provided on the upper portion of the front surface of a front wall portion (3OA) of a front-bumper reinforcement (30). A front-bumper absorber (28) is provided before the optical fiber sensor (32) and a load transfer plate (34) is disposed between the front-bumper absorber (28) and the optical fiber sensor (32). The vertical width (B3) of the front-bumper absorber (28) and the load transfer plate (34) are greater than the vertical width (Bl) of the optical fiber sensor (32), and a lower end portion (34A) of the load transfer plate (34) extends below the lower end of the optical fiber sensor (32). Accordingly, when the optical fiber sensor (32) is offset to the upper portion of the front-bumper reinforcement (30), the front-bumper absorber (28) will not topple down and the impact load is input to the optical fiber sensor (32) even if the input direction of the impact load is slightly inclined.
Abstract:
A colliding object determination device for a vehicle having a bumper reinforcement member (12) includes a sensor (20) and a determination circuit (40). The sensor (20) is located in a front portion of a vehicle for measuring a collision state quantity correlating with a collision load generated in a collision of a colliding body with the vehicle. The determination circuit (40) determines whether the colliding body is a pedestrian based on the measured collision state quantity. The sensor (20) is located on an upper half region of a front end face of the bumper reinforcement member (12). Thus, accuracy of discriminating the pedestrian from other objects can be improved.
Abstract:
Es wird eine Vorrichtung vorgeschlagen, die zur Überwachung des Aufblasverhaltens eines Airbags vorgesehen ist. Die Überwachung kann akustisch oder optisch erfolgen. Die Vorrichtung kann mit einer Ansteuervorrichtung für den Airbag derart gekoppelt sein, dass eine Regelung des Aufblasverhaltens des Airbags möglich ist.
Abstract:
The invention relates to the apparatus for and a method of sensing impact between a vehicle and an object and particularly between a pedestrian and the front bumper(12) of a vehicle. An optical fiber array(14) extends along the bumper (12) and the array (14)has sensors spaced along the bumper (12). A sensor comprises light loss areas spaced peripherally and axially on a fiber. An impact distorts the sensors, modulating light transmitted along the fiber or fibers. A signal is produced which is processed by a signal processor and an output signal generated. The output signal is used to actuate a safety device, such as elevating the vehicle hood to increase clearance between hood and engine, to reduce the severity of any injuries.

Abstract:
Die Erfindung betrifft ein Verfahren zum optischen Bestimmen des Verformungszustandes eines Sensorbandes (11), in das zum Zwecke der Bestimmung optische Fasern (12) mit biegesensitiven Bereichen (13) eingebettet sind. Im Fall einer Verformung ändert sich in den biegesensitiven Bereichen (13) die optische Dämpfung der Fasern (12), wobei die Dämpfung durch eine geeignete Sensoranordnung, die ebenfalls unter Schutz gestellt ist, ermittelt werden kann. Erfindungsgemäß ist vorgesehen, dass die sensitiven Bereiche (13) sich mit einer definierten Breite (b) überschneiden, so dass bei der Detektion von Dämpfungsveränderungen redundante Signale entstehen. In Fällen, bei denen sich die Dämpfungsveränderung aufgrund einer Biegung der sich im Abstand (a) wiederholenden Bereiche (17) prinzipbedingt aufhebt, können die redundanten Messsignale verwendet werden, um diesen Zustand zu erkennen. Der Biegesensor kann beispielsweise im Stoßfänger eines Kraftfahrzeuges zur Erkennung des Aufpralls von Fußgängern Verwendung finden.
