Stand der TechnikState of technology
Die Erfindung geht aus von einem Fahrerassistenzsystem nach der Gattung des unabhängigen Patentanspruchs.The The invention is based on a driver assistance system of the type of the independent claim.
Aus
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Fahrerassistenzsystem mit den Merkmalen des unabhängigen Patentanspruchs hat demgegenüber den Vorteil, dass zusätzlich zu dem Signal der Navigationsvorrichtung nunmehr auch das Signal einer Umfeldsensorik dazu verwendet wird, um ein eine Gefahr auf Grund des Straßenverlaufs kennzeichnendes erstes Signal zu erzeugen. Mit diesem ersten Signal können dann Eingriffe bzw. Ausgaben vorgenommen werden. Dies führt zu einer höheren Sicherheit, da insbesondere bei Kurvenfahrten das Fahrerassistenzsystem den Fahrer aktiv unterstützt. Vorteilhafter Weise kann das erfindungsgemäße Fahrerassistenzsystem durch Software realisiert werden, sofern die notwendigen Komponenten, wie ein Navigationsgerät und eine Umfeldsensorik bereits vorhanden sind. Insbesondere bei Kurvenfahrten kann durch das Fahrerassistenzsystem ein mehrstufiges Sicherheitssystem aktiviert werden: zunächst kann der Fahrer vor der Gefahr des Abkommens von der Straße in einer Kurve gewarnt werden. Dann kann die Vorbereitung des Fahrzeugs auf ein mögliches Abkommen des Fahrzeugs von der Straße, zum Beispiel durch das Anlegen von Bremsbacken, Schließen der Fenster und des Schiebedachs, sowie der Aktivierung von reversiblen Rückhaltemitteln, zum Beispiel Gurtstraffern, erfolgen. Es ist weiterhin möglich, durch Zurücknehmen der Motorleistung eine Verringerung der Geschwindigkeit zu erreichen oder auch einen Bremseingriff durchzuführen.The inventive driver assistance system with the characteristics of the independent Claim has in contrast the advantage of that in addition to the signal of the navigation device now also the signal An environment sensor is used to create a hazard Reason for the road to generate a distinctive first signal. With this first signal can then interventions or expenditures are made. This leads to a higher Safety, especially when cornering the driver assistance system actively supports the driver. Advantageously, the driver assistance system according to the invention by software be realized, provided the necessary components, such as a navigation device and environmental sensors already exist. Especially when cornering can by the driver assistance system activates a multi-level security system be: first The driver may face the danger of the agreement of the road in one Be warned curve. Then the preparation of the vehicle can be on a possible one Agreement of the vehicle off the road, for example through the Applying brake shoes, closing the windows and sunroof, as well as the activation of reversible restraints, For example, belt tensioners, done. It is still possible through withdraw the engine power to achieve a reduction in speed or to perform a braking intervention.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen des im unabhängigen Patentanspruch angegebenen Fahrerassistenzsystems möglich.By those in the dependent Claims listed measures and further developments are advantageous improvements of the independent claim specified driver assistance system possible.
Besonders vorteilhaft ist, dass das Fahrerassistenzsystem in Abhängigkeit von dem die Gefahr kennzeichnenden Signal eine Warnung ausgibt. Diese Warnung kann akustisch, optisch und/oder haptisch erfolgen. Damit kann dann der Fahrer selbständig die nötigen Eingriffe vornehmen, um ein Abkommen von der Fahrbahn in einer Kurve zu vermeiden.Especially It is advantageous that the driver assistance system in dependence of which the danger characterizing signal outputs a warning. This warning can be acoustically, visually and / or haptically. This allows the driver to independently carry out the necessary interventions, to avoid a lane departure in a curve.
Weiterhin ist es von Vorteil, dass in Abhängigkeit von diesem Signal ein Fahreingriff vorgenommen wird, beispielsweise Bremsen oder ein Zurücknehmen der Motorleistung. Damit wird der Fahrer aktiv unterstützt, um ihm die Notwendigkeit einer schnellen Reaktion abzunehmen, so dass der Fahrer dennoch mit einem Fahrzeug in die Kurve fährt, das nicht eine überhöhte Geschwindigkeit aufweist. Dies führt zu einer erhöhten Sicherheit.Farther it is an advantage that depending on from this signal a driving intervention is made, for example Braking or taking back the engine power. This actively supports the driver to to relieve him of the need for a quick response, so that the driver nevertheless drives into the curve with a vehicle that does not an excessive speed having. this leads to to an increased Safety.
Weiterhin ist es von Vorteil, dass in Abhängigkeit von diesem Signal Rückhaltemittel angesteuert werden. Damit können beispielsweise reversible Rückhaltemittel bereits aktiviert werden, und es können auch irreversible Rückhaltemittel wie Airbags in einen Vorbereitungszustand geschaltet werden, um sie dann möglichst zielgenau auslösen zu können. Dazu gehört beispielsweise das Herabsenken der Rauschschwelle im Auslösealgorithmus für den Airbag.Farther it is an advantage that depending on from this signal retention means be controlled. With that you can for example, reversible retention agents can already be activated, and it can also irreversible retention means how airbags are switched to a prepared state to them then as possible trigger accurately to be able to. To belongs for example, lowering the noise threshold in the triggering algorithm for the Airbag.
Weiterhin ist es von Vorteil, dass bei der Erzeugung des die Gefahr kennzeichnenden Signals auch ein Signal von einer Umweltsensorik berücksichtigt wird. Dazu gehören Signale, die die Witterungseinflüsse kennzeichnen, wie beispielsweise Regen, Nebel, Glatteis. Damit können dann insbesondere Rückschlüsse auf die Fahrbahnbeschaffenheit gezogen werden, um bei einem automatischen Eingriff in das Fahrverhalten solche Eingriffe vorzunehmen, die diese Witterungseinflüsse berücksichtigen.Farther it is advantageous that in the generation of the danger characterizing Signals are also considered a signal from an environmental sensor becomes. This includes Signals that influence the weather such as rain, fog, black ice. With that you can in particular conclusions the road condition can be pulled to an automatic engagement to make such interventions in the driving behavior that take into account these weather conditions.
Weiterhin ist es von Vorteil, dass das Fahrerassistenzsystem mittels der Umfeldsensorik Fahrbahnmarkierungen wie Leitpfosten beobachtet, um daraus einen Kurvenradius zu bestimmen. Aus dem Kurvenradius und der Eigengeschwindigkeit kann dann die zu erwartende Querbeschleunigung in der Kurve bestimmt werden, um daraus die Gefahr zu bestimmen. Insbesondere kann daraus bestimmt werden, ob das Fahrzeug in der Kurve die Haftung verliert und damit der Fahrzustand instabil werden könnte. Voraussetzung dafür ist, dass eine Haftschlussgrenze bekannt ist, die bei trockener Fahrbahn ungefähr gleich der Erdbeschleunigung ist. Liegt die Gefahr des Verlierens der Haftung in der Kurve nahe, dann kann das Fahrerassistenzsystem die Eigengeschwindigkeit vor der Kurve verringern, um die Fahrzeugstabilität zu gewährleisten. Hier kann insbesondere die Information der Umweltsensorik mitberücksichtigt werden, um die Haftschlussgrenze zu adaptieren. Zusätzlich kann dabei mit der Umfeldsensorik im Nahbereich der Abstand zum Straßenrand ermittelt werden. Auch dieses Datum kann dazu verwendet werden, um die Fahrzeugsicherheit zu erhöhen und um entsprechende Maßnahmen einzuleiten.Furthermore, it is advantageous for the driver assistance system to observe road markings, such as guide posts, by means of the environmental sensor system in order to determine a curve radius therefrom. The expected lateral acceleration in the curve can then be determined from the curve radius and the airspeed in order to determine the danger. In particular, it can be determined from this whether the vehicle loses its grip in the curve and thus the driving state could become unstable. The prerequisite for this is that a liability limit is known, which is approximately equal to the acceleration of gravity when the road is dry. If there is a risk of losing the grip in the corner, then the driver assistance system can reduce the airspeed before the turn to ensure vehicle stability. Here, in particular, the information of the environmental sensors can be taken into account in order to adapt the liability limit. In addition, the proximity to the roadside can be determined with the environment sensor in the near range. This date can also be used to increase vehicle safety and to take appropriate action.

Beschreibungdescription
Bisher werden Ortungssysteme eingesetzt, um in Navigationssystemen dem Fahrer den Weg zu weisen. Bei der Umfeldsensorik gibt es beispielsweise Radarsysteme für große Entfernungen mit Reichweiten von bis zu 180 Metern, die beispielsweise in Abstandswarnern eingesetzt werden. Es sind jedoch auch Radar- und Ultraschallsysteme bekannt, die nur bis zu einer Reichweite von 20 Metern operieren.So far positioning systems are used in navigation systems To show the driver the way. For environment sensors, for example Radar systems for size Distances with ranges of up to 180 meters, for example be used in distance warnings. However, there are also radar and ultrasound systems are known that only reach up to a range operate from 20 meters.
Mit dem Fahrerassistenzsystem werden nunmehr während der Fahrt mit Hilfe von Navigationsdaten und Daten der Umfeldsensorik Kurven erkannt und deren Radien bestimmt. Dadurch kann mit Informationen aus der Fahrdynamik, zum Beispiel der Eigengeschwindigkeit, und Umweltbedingungen, zum Beispiel der Außentemperatur oder anderen Sensoren, die den Straßenzustand charakterisieren, ein mögliches Gefahrenpotential zum Abkommen von der Straße in der Kurve ermittelt werden.With the driver assistance system are now while driving with the help of Navigation data and data of the environment sensor curves detected and their radii determined. This can be done with information from the driving dynamics, for example, the airspeed, and environmental conditions, to Example of the outside temperature or other sensors that characterize the road condition potential Risk potential to the agreement of the road in the curve to be determined.
Das GPS-System erkennt in Zusammenarbeit mit den Navigationsdaten Kurven, und, sofern es in der Navigationsdatenbank vorhanden ist, auch den Kurvenradius. Falls der Kurvenradius nicht aus den Navigationsdaten zu ermitteln ist, kann mit Hilfe der Umfeldsensorik der Kurvenradius ermittelt werden. Die Umfeldsensorik nutzt dazu beispielsweise Fahrbahnmarkierungen wie Leitpfosten, die bei Kurven andere Positionen haben. Durch die Positionen der Leitpfosten kann eine Kurve gelegt werden, wobei die Krümmung dieser Kurve gleich der Inversen des Planradius ist. Bei einem Videosystem kann aus dem Bild direkt der Kurvenradius, beispielsweise durch Bestimmung des Fahrbahnrandes, ermittelt werden.The GPS system recognizes curves in cooperation with the navigation data and, if available in the navigation database, also the curve radius. If the curve radius is not determined from the navigation data is, the corner radius can be determined with the help of environment sensors become. The environment sensor system uses, for example, lane markings like delineators that have different positions when cornering. By the Positions of the delineators can be placed a curve, where the curvature this curve is equal to the inverse of the plan radius. In a video system can from the image directly the radius of curvature, for example by determination of the roadside, be determined.
Aus dem Bahnradius und der Eigengeschwindigkeit kann die in der Kurve zu erwartende Querbeschleunigung bestimmt werden. Liegt diese nahe an der Haftschlussgrenze, die bei trockener Fahrbahn ungefähr gleich der Erdbeschleunigung ist, oder sogar darüber, so kann vorausgesagt werden, dass das Fahrzeug in der Kurve die Haftung verlieren und somit der Fahrzustand instabil wird. Also ist ein Verringern der Eigengeschwindigkeit vor der Kurve notwendig. Hier kommt nun das Fahrerassistenzsystem ins Spiel. Durch Einbeziehen der Außentemperatur, der Informationen eines Regensensors oder Informationen über den Straßenzustand, kann auf eine Verringerung der Haftschlussgrenze durch Umweltbedingungen geschlossen werden, so dass eine frühere Aktivierung des Sicherheitssystems bei Regen, Schnee oder Eis ermöglicht wird. Unter Sicherheitssystem wird hier ein Eingriff in das Fahrverhalten bzw. die Aktivierung von Rückhaltemitteln verstanden.Out the orbit radius and the own speed can be in the curve expected lateral acceleration can be determined. Is this close? at the adhesion limit, which is about the same on a dry road acceleration, or even acceleration, it can be predicted that the vehicle in the curve lose liability and thus the driving condition becomes unstable. So is a reduction in airspeed necessary in front of the bend. Here comes the driver assistance system in the game. By incorporating the outside temperature, the information a rain sensor or information about road conditions, may be due to a reduction in the liability limit due to environmental conditions be closed, allowing an earlier activation of the security system in rain, snow or ice becomes. Under security system here is an intervention in the driving behavior or the activation of restraints Understood.
Mit der Umfeldsensorik kann zusätzlich im Nahbereich der Abstand zum Straßenrand ermittelt werden. Durch weitere Informationen, wie die Eigengeschwindigkeit, Straßenzustand, Außentemperatur und Regensensor kann daraus bestimmt werden, ob das Fahrzeug die Kurve gefahrlos fahren kann oder von der Kurve mit hoher Wahrscheinlichkeit abkommen wird. Ist das Abkommen von der Straße wahrscheinlich, so kann das Fahrerassistenzsystem die Sicherheitsmaßnahmen einleiten.With The environment sensor can additionally be determined in the vicinity of the distance to the roadside. By further information, such as the airspeed, road conditions, Outside temperature and Rain sensor can be determined from whether the vehicle is the curve can drive safely or from the curve with high probability will come to an agreement. If the agreement from the road is likely, then the driver assistance system initiate the safety measures.
