Abstract
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrzeuges (1), wobei eine momentane Fahrgeschwindigkeit des Fahrzeuges (1) erfasst wird. Erfindungsgemäß wird eine maximal mögliche Fahrgeschwindigkeit zur Durchfahrt einer dem Fahrzeug (1) vorausliegenden Kurve (K) ermittelt, wobei im Fall einer erfassten Annäherung der momentanen Fahrgeschwindigkeit des Fahrzeuges (1) an die maximal mögliche Fahrgeschwindigkeit zur Durchfahrt der Kurve (K) ein Warnhinweis an einen Fahrzeugnutzer des Fahrzeuges (1) ausgegeben wird und bei erfasster Nichtverringerung der momentanen Fahrgeschwindigkeit ein Bremseingriff des Fahrzeuges (1) automatisch eingeleitet wird.The invention relates to a method for operating a vehicle (1), wherein a current driving speed of the vehicle (1) is recorded. According to the invention, a maximum possible driving speed for driving through a curve (K) ahead of the vehicle (1) is determined, wherein in the event of a detected approximation of the current driving speed of the vehicle (1) to the maximum possible driving speed for driving through the curve (K), a warning is given a vehicle user of the vehicle (1) is output and a braking intervention of the vehicle (1) is automatically initiated when the current driving speed is not reduced.
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrzeuges, wobei eine momentane Fahrgeschwindigkeit des Fahrzeuges erfasst wird.The invention relates to a method for operating a vehicle, a current driving speed of the vehicle being recorded.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betrieb eines Fahrzeuges anzugeben.The invention has for its object to provide a method for operating a vehicle.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, welches die in Anspruch 1 angegebenen Merkmale aufweist.The object is achieved according to the invention by a method which has the features specified in claim 1.
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 Fahrzeuges, wobei eine momentane Fahrgeschwindigkeit des Fahrzeuges erfasst wird, sieht erfindungsgemäß vor, dass eine maximal mögliche Fahrgeschwindigkeit zur Durchfahrt einer dem Fahrzeug vorausliegenden Kurve ermittelt wird, wobei im Fall einer erfassten Annäherung der momentanen Fahrgeschwindigkeit des Fahrzeuges an die maximal mögliche Fahrgeschwindigkeit zur Durchfahrt der Kurve ein Warnhinweis an einen Fahrzeugnutzer des Fahrzeuges ausgegeben wird und bei erfasster Nichtverringerung der momentanen Fahrgeschwindigkeit ein Bremseingriff des Fahrzeuges automatisch eingeleitet wird. According to the invention, a method for operating a vehicle, wherein a current driving speed of the vehicle is recorded, provides that a maximum possible driving speed for driving through a curve ahead of the vehicle is determined, wherein in the case of a detected approximation of the current driving speed of the vehicle to the maximum possible Driving speed for driving through the curve, a warning is issued to a vehicle user of the vehicle and, if the current driving speed is not reduced, a braking intervention of the vehicle is automatically initiated.
Durch Anwendung des Verfahrens wird das Risiko, dass das Fahrzeug wegen seiner überhöhten momentanen Fahrgeschwindigkeit und dadurch bedingter Fliehkräfte aus der Kurve herausgetragen wird, wesentlich verringert. Somit kann weitestgehend ausgeschlossen werden, dass das Fahrzeug verunglückt, wodurch gegebenenfalls Leben gerettet werden kann.By using the method, the risk of the vehicle being carried out of the curve due to its excessive current driving speed and the resulting centrifugal forces is substantially reduced. It can therefore be largely excluded that the vehicle has an accident, which may save lives.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to a drawing.
Dabei zeigt:
-
1 schematisch ein Fahrzeug vor einer Einfahrt in eine Kurve.
-
1 schematically a vehicle before entering a curve.
Die einzige Figur zeigt einen Fahrbahnabschnitt
Im Allgemeinen ist bekannt, dass Fahrzeugnutzer aufgrund von Fehleinschätzungen, insbesondere in Bezug auf eine Fahrgeschwindigkeit, zu schnell in eine Kurve
Um das Risiko zu verringern, dass das Fahrzeug
Bei Anwendung des Verfahrens wird anhand verschiedenster Parameter eine maximal mögliche Fahrgeschwindigkeit ermittelt, mit welcher die Kurve
Beispielsweise wird die maximal mögliche Fahrgeschwindigkeit zur Durchfahrt der vorausliegenden Kurve
Insbesondere kann anhand der Parameter eine Haftreibungskraft ermittelt werden, die von der Fahrbahnbeschaffenheit abhängig ist.For example, the maximum possible driving speed for passing the curve ahead
In particular, a static friction force can be determined on the basis of the parameters, which is dependent on the nature of the road.
