Offenbarung der ErfindungDisclosure of the invention
Die Erfindung betrifft ein Verfahren zur Verringerung der Gefährdung des Fahrers eines einspurigen Kraftfahrzeugs im Falle einer Kollision, bei dem
- - mittels einer den vor dem Kraftfahrzeug liegenden Bereich erfassenden Umfeldsensorik ermittelt wird, ob eine Kollisionsgefahr für das einspurige Kraftfahrzeug vorliegt,
- - bei Vorliegen einer Kollisionsgefahr eine fahrerunabhängige Beeinflussung des Feder-Dämpfer-Systems am Vorderrad des einspurigen Kraftfahrzeugs stattfindet.
- - by means of an environment sensor system that detects the area in front of the motor vehicle, it is determined whether there is a risk of collision for the single-lane motor vehicle,
- - When there is a risk of collision, the driver-independent influencing of the spring-damper system on the front wheel of the single-track motor vehicle takes place.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass ermittelt wird, ob die Kollisionsgefahr derart groß ist, dass eine Kollision durch den Fahrer nicht mehr verhinderbar ist und dass bei Vorliegen einer derartigen Kollisionsgefahr das Feder-Dämpfer-System derart beeinflusst wird, dass die Frontgabel des einspurigen Kraftfahrzeugs angehoben wird.An advantageous embodiment of the invention is characterized in that it is determined whether the risk of collision is so great that a collision can no longer be prevented by the driver and that, if there is such a risk of collision, the spring-damper system is influenced in such a way that the front fork of the single-track motor vehicle is raised.
Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass zusätzlich die Aufhängung des Hinterrads derart beeinflusst wird, dass das Fahrwerk des Hinterrads abgesenkt wird.An advantageous embodiment of the invention is characterized in that the suspension of the rear wheel is also influenced in such a way that the chassis of the rear wheel is lowered.
Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass das Vorliegen einer Kollisionsgefahr anhand der von einer Videosensorik und/oder einer Radarsensorik ermittelten Daten ermittelt wird.An advantageous embodiment of the invention is characterized in that the presence of a risk of collision is determined on the basis of the data determined by a video sensor system and / or a radar sensor system.
Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass es sich bei dem einspurigen Kraftfahrzeug um ein Motorrad handelt.An advantageous embodiment of the invention is characterized in that the single-track motor vehicle is a motorcycle.
Weiter umfasst die Erfindung eine Vorrichtung, enthaltend Mittel, die zur Durchführung der erfindungsgemäßen Verfahren ausgestaltet sind. Dabei handelt es sich insbesondere um ein Steuergerät, in welchem der Programmcode zur Durchführung der erfindungsgemäßen Verfahren hinterlegt ist.The invention further comprises a device containing means which are designed to carry out the method according to the invention.

2 shows schematically the impact of a motorcycle on a car as well as a possible direction of fall for the driver without extended front fork and with extended front fork. -

Bei einem Frontalaufprall eines Motorrads gegen ein Hindernis besteht die Gefahr, dass sich das Motorrad mit dem Hinterrad aufstellt, da durch den tiefliegenden Kontaktpunkt zwischen dem Vorderrad des Motorrads und dem Hindernis bei einer Kollision große Drehmomente auftreten. Der Aufsasse wird hier meist nicht verzögert und prallt mit nahezu voller Kollisionsgeschwindigkeit in den Unfallgegner. Im schlechtesten Fall trifft der Aufsasse dabei sehr steife Strukturen, wie beispielsweise die A- oder B-Säule eines PKW oder dessen Dachreeling mit meist sehr schweren Verletzungen. Der Effekt wird zudem durch ein Eintauchen der Frontgabel bei etwaigem starken Bremsen vor dem Unfall noch verstärkt.In the event of a frontal impact of a motorcycle against an obstacle, there is a risk that the motorcycle will stand up with the rear wheel, since large torques occur in the event of a collision due to the low contact point between the front wheel of the motorcycle and the obstacle. The rider is usually not delayed here and crashes into the other party in the accident at almost full collision speed. In the worst case, the rider hits very stiff structures, such as the A or B pillar of a car or its roof railing, usually with very serious injuries. The effect is further reinforced by the front fork dipping in the event of heavy braking before the accident.
Die Erfindung befasst sich mit der bestmöglichen Vorbereitung bzw. Ausrichtung des Motorrads bzw. des Aufsassen vor einer drohenden bzw. nicht mehr abwendbaren Frontkollision. Durch frühzeitiges Erkennen einer solchen Gefahrensituation soll die Frontpartie des Motorrads so angehoben werden das mehr verformbare Strukturen des Motorrads zwischen dem Kollisionsgegner und dem Aufsassen platziert wird und zudem eine Art „Rampeneffekt“ generiert wird, der es dem Aufsassen ermöglichen soll über das Hindernis geworfen zu werden anstelle auf dieses zu prallen.The invention is concerned with the best possible preparation or alignment of the motorcycle or the rider before an impending or no longer avertable frontal collision. By recognizing such a dangerous situation at an early stage, the front section of the motorcycle should be raised so that more deformable structures of the motorcycle are placed between the collision opponent and the rider and a kind of "ramp effect" is generated, which should enable the rider to be thrown over the obstacle instead of crashing into it.
Die im folgenden beschriebene Funktion ist in der Lage aus den Signalen der Sensorik am Motorrad die vor ihm liegende Verkehrssituation zu erkennen und zu bewerten. Das ist vergleichbar mit Systemen zur automatischen Abstandsregelung aus dem PKW-Bereich basierend auf Kamera- oder Radarsystemen. In
Weiter ist das Motorrad mindestens an der Frontgabel mit einem aktiven Feder-Dämpfer-System ausgestattet, optional ist für eine weitere Ausbaustufe ein aktives Feder-Dämpfer-System zusätzlich an der Hinterradaufhängung vorgesehen.In addition, the motorcycle is equipped with an active spring-damper system at least on the front fork; an active spring-damper system is also optionally provided on the rear suspension for a further expansion stage.
Im Fokus liegt die optimierte Ausrichtung des Motorrads bzw. Aufsassen auf eine bevorstehende und unausweichliche Kollision mit einem Hindernis, z.B. einem PKW. Die erfolgt durch ein Straffen oder sogar ein aktives Anheben des Fahrwerks an der Frontpartie des einspurigen Kraftfahrzeugs bzw. Motorrads.The focus is on the optimized alignment of the motorcycle or rider to an imminent and inevitable collision with an obstacle, e.g. a car. This is done by tightening or even actively lifting the chassis at the front of the single-track motor vehicle or motorcycle.

Die einzelnen Verfahrensschritte einer Ausgestaltung der Erfindung bei Gefahr einer Frontkollision sind in
- Nach dem Start in Block
301 wird in Block302 abgefragt, ob eine Kollisionsgefahr für das Motorrad vorliegt. Ein Fahrerassistenzsystem des Motorrads mit einer Umfeldsensorik, z.B. mittels einer Kamera, überwacht den vor dem Fahrzeug liegenden Streckenabschnitt und bewertet mögliche Hindernisse auf deren Relevanz und mögliche Kollisionen. Wird die Situation als unkritisch bewertet verbleibt das Fahrwerk in Block303 in seinem vom Fahrer definierten Zustand. Wird die Situation als kritisch bewertet, dann wird zu Block304 weitergegangen.
- After starting in
block 301 will be inblock 302 asked whether there is a risk of collision for the motorcycle. A driver assistance system of the motorcycle with an environment sensor system, for example by means of a camera, monitors the route section in front of the vehicle and evaluates possible obstacles for their relevance and possible collisions. If the situation is assessed as uncritical, the chassis remains inblock 303 in its driver-defined state. If the situation is assessed as critical, it becomesblock 304 went on.

Wird von der Umfeldsensorik eine bedrohliche Situation erkannt welche unwiderruflich zu einer Kollision führt, dann wird die Frontgabel extrem bzw. maximal ausgefahren um sich auf den Aufprall vorzubereiten.If the environment sensor detects a threatening situation which irrevocably leads to a collision, the front fork is extended to the extreme or to the maximum in order to prepare for the impact.
