Abstract

A first signal delivered by a sensor device uses a control device to trigger a second signal that serves to trigger a restraining device, e.g. a safety belt tightening device and/or an airbag device, for a driver. If there is a second signal, the control device emits a third signal that triggers a device for locking an operating/gas pedal.

Description

Die Erfindung betrifft ein Rückhalteverfahren zum Insassenschutz für einen Fahrer eines Kraftfahrzeugs nach dem Oberbegriff des Hauptanspruchs.The invention relates to a retention method for Occupant protection for a driver of a motor vehicle according to the preamble of the main claim.

Aus der EP 0 471 871 B1 ist eine Anordnung zum Auslösen eines Rückhaltemittels in einem Fahrzeug bekannt. Diese Anordnung enthält eine zentral im Fahrzeug angeordnete Auswerteeinrichtung, in der ein von einer Sensoreinrichtung geliefertes Aufprallsignal ausgewertet wird. Die Anordnung weist weiterhin auf das Fahrzeug verteilte Zündeinrichtungen auf, die über eine oder mehrere Leitungen mit der Auswerteeinrichtung verbunden sind. Die Auswerteeinrichtung liefert codierte Signale an die Zündeinrichtungen. Jede Zündeinrichtung ist mit einem Zündelement eines Rückhaltemittels, z. B. einem Airbag oder einem Gutstraffer, elektrisch verbunden. Abhängig von den von der Auswerteeinrichtung gelieferten Signalen wird das einer Zündeinrichtung zugeordnete Zündelement mit Energie aus einem Zündkondensator der Zündeinrichtung beaufschlagt und so das zugeordnete Rückhaltemittel ausgelöst.From the EP 0 471 871 B1 an arrangement for triggering a restraint in a vehicle is known. This arrangement contains an evaluation device arranged centrally in the vehicle, in which an impact signal supplied by a sensor device is evaluated. The arrangement also has ignition devices distributed to the vehicle, which are connected to the evaluation device via one or more lines. The evaluation device supplies coded signals to the ignition devices. Each ignition device is equipped with an ignition element of a restraint, e.g. B. an airbag or a tensioner electrically connected. Depending on the signals supplied by the evaluation device, the ignition element assigned to an ignition device is acted upon by energy from an ignition capacitor of the ignition device and the associated restraint means is thus triggered.

Eine solche Anordnung zum Auslösen von Rückhaltemitteln wird zwar bereits für Airbags oder Gurtstraffer angewendet, aber nicht für ein Rückholsystem für das Pedalsystem und/oder die Lenksäule von Kraftfahrzeugen, wie in DE 43 40 633 A1 beschrieben. Dieses System zur Erhöhung der Insassensicherheit besitzt ein Betätigungselement, das aufprallbedingt auslöst, wenn der Wagenvorbau teilweise deformiert wird und dabei eine Deformation der Spritzwand oder eines ähnlich steifen Bauteiles erfolgt. Durch das Betätigungselement wird ein Hebel in Vorwärtsfahrtrichtung des Kraftfahrzeugs verschwenkt, wobei gleichzeitig die am freien Ende des Hebels angekuppelten Systeme wie Lenksäule und/oder Pedalsystem bewegt werden. Die Lenksäule wird entsprechend der einstellbaren Hebelbewegung beispielsweise um 120 mm zurückgezogen und das Pedalsystem wird aus dem Fußweg des Fahrers weggezogen.Such an arrangement for triggering restraint devices is already used for airbags or belt tensioners, but not for a return system for the pedal system and / or the steering column of motor vehicles, as in DE 43 40 633 A1 described. This system for increasing occupant safety has an actuating element that triggers on impact if the car stem is partially deformed and the bulkhead or a similarly rigid component is deformed. The actuating element pivots a lever in the forward direction of travel of the motor vehicle, the systems coupled to the free end of the lever, such as the steering column and / or pedal system, being moved at the same time. The steering column is retracted by 120 mm, for example, in accordance with the adjustable lever movement, and the pedal system is pulled away from the driver's footpath.

Ein solches mechanisches Rückholsystem für die Pedalerie eines Kraftfahrzeugs kann den Nachteil haben, dass zum Beispiel ein Bein eines Fahrers nach dem Wegschwenken des Pedalsystems unter Umständen Bewegungsenergie aufbauen kann, die nachfolgend am Fahrzeugboden oder an der Spritzwand unter Umständen wieder abgebaut wird. Dabei können den Umständen entsprechend hohe Kontaktkräfte auf den Vorderfußbereich des Fahrers induziert werden.Such a mechanical return system for the pedals of a motor vehicle can have the disadvantage that, for example a driver's leg after swinging the pedal system under circumstances Can build kinetic energy, which subsequently on the vehicle floor or may be dismantled on the bulkhead. You can the circumstances correspondingly high contact forces on the forefoot area of the driver.

Aufgabe der Erfindung ist es einen Beitrag zum verletzungsarmen Fußraum im Kraftfahrzeug bereitzustellen.The object of the invention is a Contribution to the low-injury footwell to be provided in the motor vehicle.

Die Aufgabe wird erfindungsgemäß mit den Verfahrensschritten des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The object is achieved according to the method steps of claim 1 solved. Further refinements of the invention result from the subclaims.

Die Erfindung beschreibt ein Rückhalteverfahren zum Insassenschutz für einen Fahrer eines Kraftfahrzeugs. Ein von einer Sensoreinrichtung geliefertes erstes Signal löst über eine Steuereinrichtung mindestens ein zweites Signal aus, das zum Auslösen einer Rückhalteeinrichtung für den Fahrer dient, insbesondere einer Sicherheitsgurtstraffeinrichtung und/oder einer Airbageinrichtung. Das Rückhalteverfahren ist dadurch gekennzeichnet, dass die Steuereinrichtung bei Vorliegen des zweiten Signals ein drittes Signal abgibt, das eine Einrichtung zum Blockieren eines Bedienpedals auslöst.The invention describes a retention method for occupant protection for a driver of a motor vehicle. One from a sensor device delivered first signal triggers via a Control device from at least a second signal that is used to trigger a Restraint for the Driver serves, in particular a seat belt tightening device and / or an airbag device. The retention process is thereby characterized in that the control device in the presence of the second Signals a third signal that a device for blocking of an operating pedal triggers.

Das hat den Vorteil, dass das Bedienpedal im Crashfall in der Stellung arretiert wird, die es bei Crashbeginn besitzt. Über einen Dämpfer kann aus dieser Stellung eine geringe Vorverlagerung noch ermöglicht werden. Eine solche starre Arretierung des Bedienpedals während eines Unfalls kann das Verletzungsrisiko der unteren Extremitäten unter Umständen verkleinern. Technisch kann eine solche Arretierung durch einen Verriegelungs- oder Klemmmechanismus im Bedienpedal realisiert werden.This has the advantage that the control pedal in the Crash case is locked in the position it was at the beginning of the crash has. about a damper a slight advance can still be made possible from this position. Such a rigid locking of the control pedal during a Accident can lower the risk of injury to the lower extremities circumstances out. Technically, such a lock by a Locking or clamping mechanism can be realized in the control pedal.

Bei einer vorteilhaften Ausführungsform der Erfindung ist das Bedienpedal ein Gaspedal und/oder ein Kupplungspedal.In an advantageous embodiment According to the invention, the control pedal is an accelerator pedal and / or a clutch pedal.

Bei einer weiteren vorteilhaften Ausführungsform des Verfahrens wird genau das Bedienpedal durch die Einrichtung zum Blockieren des Bedienpedals blockiert, das durch den Fahrer gerade bedient wird, wenn das zweite Signal von der Steuereinrichtung abgegeben wird.Another advantageous embodiment The procedure is exactly the control pedal by the device to block the control pedal blocked by the driver is being operated when the second signal from the control device is delivered.

Nachfolgend wird ein möglicher Verfahrensablauf zum Blockieren eines gerade von einem Fahrer betätigten Bedienpedals beschrieben.Below is a possible one Procedure for blocking a control pedal that is currently being operated by a driver described.

Ein Fahrer eines Fahrzeugs verursacht einen Unfall, dessen Intensität einen in einer Steuereinrichtung vorgegebenen Schwellwert für ein erstes Signal einer Sensoreinrichtung zum Auslösen einer Gurtstrammeinrichtung übersteigt. Das von der Sensoreinrichtung an die Steuereinrichtung abgegebene erste Signal bewirkt ein Auslösen der Gurtstrammeinrichtung, indem ein zweites Signal von der Steuereinrichtung an die Gurtstrammeinrichtung abgegeben wird. Gleichzeitig gibt die Steuereinrichtung ein drittes Signal an eine Einrichtung zum Blockieren eines Gaspedals ab, da dieses zum Zeitpunkt des Unfalls durch den Fahrer in einer Mittelstellung niedergedrückt ist. Das Gaspedal wird in dieser Mittelstellung durch die Einrichtung zum Blockieren des Gaspedals blockiert. Dadurch wird versucht sicherzustellen, dass der sich auf dem Gaspedal befindliche Fuß des Fahrers, durch auf diesen beim Unfall wirkende Kräfte und Momente, nicht weiter in den Fußraum des Fahrzeugs hinein bewegt. Über einen Dämpfer im Verriegelungs- oder Klemmmechanismus für das Gaspedal wird noch eine geringe Vorverlagerung des Fußes bei sehr hoher Belastung ermöglicht.A driver of a vehicle causes an accident, the intensity of which exceeds a threshold value specified in a control device for a first signal from a sensor device for triggering a belt tensioning device. The first signal emitted by the sensor device to the control device triggers the belt pretensioner in that a second signal is emitted by the control device to the belt pretensioner. At the same time, the control device emits a third signal to a device for blocking an accelerator pedal, since it is depressed in a middle position by the driver at the time of the accident. In this middle position, the accelerator pedal is blocked by the device for blocking the accelerator pedal. This tries to ensure that the driver's foot on the accelerator pedal acts on the driver's foot in the event of an accident Forces and moments not moved further into the footwell of the vehicle. A damper in the locking or clamping mechanism for the accelerator pedal enables the foot to be moved slightly forward under very high loads.

Auf entsprechende Weise ist es auch möglich, ein Kupplungspedal zu blockieren, wie beim Gaspedal, entweder grundsätzlich ab einer bestimmten Intensität eines Unfalls oder nur im Falle einer Betätigung der Kupplung durch den Fahrer während des Unfalls.In a similar way it is possible, to block a clutch pedal, as with the accelerator, either in principle of a certain intensity an accident or only if the clutch is actuated by the Driver during of the accident.
