Abstract
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges (1), wobei in einer Umgebung des Fahrzeuges (1) befindliche Objekte erfasst werden. Erfindungsgemäß werden eine Trajektorie des Fahrzeuges (1) und eine Trajektorie zumindest eines Objektes ermittelt, wobei anhand der ermittelten Trajektorien die Wahrscheinlichkeit einer Kollision zwischen dem Fahrzeug (1) und dem Objekt ermittelt wird und bei Überschreitung eines vorgegebenen Wahrscheinlichkeitsgrenzwertes eine Beschleunigung des Fahrzeuges (1) automatisch begrenzt wird.The invention relates to a method for operating a driver assistance system of a vehicle (1), wherein objects located in an environment of the vehicle (1) are detected. According to the invention, a trajectory of the vehicle (1) and a trajectory of at least one object are determined, the probability of a collision between the vehicle (1) and the object being determined on the basis of the determined trajectories, and an acceleration of the vehicle (1) when exceeding a predetermined probability limit value. is automatically limited.
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges, wobei in einer Umgebung des Fahrzeuges befindliche Objekte erfasst werden.The invention relates to a method for operating a driver assistance system of a vehicle, wherein objects located in an environment of the vehicle are detected.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges anzugeben.The invention has for its object to provide a comparison with the prior art improved method for operating a driver assistance system of a vehicle.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Verfahren zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges sieht vor, dass in einer Umgebung des Fahrzeuges befindliche Objekte erfasst werden. Erfindungsgemäß werden eine Trajektorie des Fahrzeuges und eine Trajektorie zumindest eines Objektes ermittelt, wobei anhand der ermittelten Trajektorien die Wahrscheinlichkeit einer Kollision zwischen dem Fahrzeug und dem Objekt ermittelt wird und bei Überschreitung eines vorgegebenen Wahrscheinlichkeitsgrenzwerts eine Beschleunigung des Fahrzeuges automatisch begrenzt wird.A method for operating a driver assistance system of a vehicle provides that objects located in an environment of the vehicle are detected. According to the invention, a trajectory of the vehicle and a trajectory of at least one object are determined, the probability of a collision between the vehicle and the object being determined on the basis of the determined trajectories, and an acceleration of the vehicle being automatically limited if a predetermined probability limit value is exceeded.
Durch Anwendung des Verfahrens wird ein solcher Fahrzeugnutzer unterstützt, welcher eine Situation, beispielsweise beim Linksabbiegen auf einer Kreuzung mit querendem Verkehr, falsch einschätzt oder die vorliegende Situation übersieht.By applying the method, such a vehicle user is supported, who misjudges a situation, for example, when turning left on a crossroads crossing, or overlooks the present situation.
Ein Fahrzeugnutzer, der die Situation richtig einschätzt, wird durch die Vorgabe einer maximal möglichen Beschleunigung nicht beeinflusst, da er das Fahrzeug selbst nicht höher beschleunigen würde.A vehicle user who correctly assesses the situation is not affected by the specification of a maximum possible acceleration, since he would not accelerate the vehicle itself higher.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert.Embodiments of the invention are explained in more detail below with reference to drawings.

Das Fahrzeug
Hierbei besteht die Gefahr, dass der Fahrzeugnutzer des Fahrzeuges
Darüber hinaus besteht ein Risiko bei einem solchen automatischen Eingriff in die Bremsvorrichtung darin, dass dieser zu früh eingeleitet wird und eigentlich keine kritische Situation vorliegt, wofür der Fahrzeugnutzer wenig Verständnis aufbringt, oder dass der Eingriff zu spät eingeleitet wird und die Kollision nicht mehr verhindert werden kann.In addition, there is a risk in such an automatic intervention in the braking device that it is initiated too early and actually no critical situation, for which the vehicle user does not understand, or that the intervention is initiated too late and the collision is no longer prevented can.
Um den Fahrzeugnutzer des Fahrzeuges
Da die Sensoren der Umgebungssensorik eine vergleichsweise hohe Reichweite, also einen vergleichsweise großen Erfassungsbereich, aufweisen, ist vorgesehen, dass eine solche oben erwähnte Situation erfasst wird und automatisch eingegriffen wird, bevor eine Kollision des Fahrzeuges
Hierzu ist vorgesehen, dass mittels der Umgebungssensorik das weitere Fahrzeug
Wird eine vergleichsweise hohe Wahrscheinlichkeit ermittelt, d. h. wird ein vorgegebener Wahrscheinlichkeitswert überschritten, wird mittels eines Fahrerassistenzsystems eine Beschleunigung des Fahrzeuges
In
Zusätzlich zur Begrenzung der Beschleunigung des Fahrzeuges
Die gleiche Verkehrssituation ist in
Dabei wird die Beschleunigung derart begrenzt, dass für die beiden Fahrzeuge
Bei einer entsprechend erfassten Verkehrssituation wird die Beschleunigung des Fahrzeuges
Ein Fahrzeugnutzer des Fahrzeuges
Übersieht der Fahrzeugnutzer die vorliegenden Verkehrssituation, wird der Fahrzeugnutzer ohne einen oftmals erschreckend wirkenden Bremseingriff im unfallfreien Fahrbetrieb unterstützt.If the vehicle user overlooks the present traffic situation, the vehicle user is supported without an often frightening braking intervention in accident-free driving operation.
