Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Erhöhung einer Reflexionscharakteristik und einer Reichweite eines an einem Fahrzeug angeordneten Eckreflektors anzugeben.The invention is based on the object of specifying a method for increasing a reflection characteristic and a range of a corner reflector arranged on 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
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.
Ein Verfahren zur Erhöhung einer Reflexionscharakteristik und einer Reichweite eines an einem Fahrzeug angeordneten Radarreflektors sieht erfindungsgemäß vor, dass der Radarreflektor zumindest in Abhängigkeit einer anhand von Navigationsdaten ermittelten Trajektorie eines dem Fahrzeug nachfolgenden Fahrzeuges und/oder in Abhängigkeit erfasster Signale einer Umgebungssensorik des Fahrzeuges ausgerichtet wird.According to the invention, a method for increasing a reflection characteristic and a range of a radar reflector arranged on a vehicle provides that the radar reflector is aligned at least as a function of a trajectory of a vehicle following the vehicle that is determined on the basis of navigation data and / or as a function of detected signals from an environmental sensor system of the vehicle.
Durch Anwendung des Verfahrens können Rückstrahleigenschaften des Radarreflektors eines Verkehrsteilnehmers, z. B. eines Fahrzeuges, Fahrrades und/oder auch einer Person, erhöht werden. Somit kann ermöglicht werden, dass ein Fahrerassistenzsystem des Fahrzeuges den Verkehrsteilnehmer mit einem solchen Radarreflektor gegebenenfalls zeitlich früher wahrnimmt und so eine Kollision mit dem Verkehrsteilnehmer verhindert werden kann oder zumindest eine Kollisionsschwere verringert werden kann, da das Fahrzeug entsprechend reagieren kann und beispielsweise eine Notbremsung einleitet.By using the method, the reflective properties of the radar reflector of a road user, e.g. B. a vehicle, bicycle and / or a person. This makes it possible for a driver assistance system of the vehicle to perceive the road user with such a radar reflector earlier if necessary and thus prevent a collision with the road user or at least reduce the severity of the collision, since the vehicle can react accordingly and, for example, initiate emergency braking.
