Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betrieb eines FahrerassistenzsystemsThe The invention relates to a method and an apparatus for operation a driver assistance system
Im Allgemeinen ist bekannt, dass bei einem Fahrerassistenzsystem zur Unterstützung eines Fahrzeugführers bei einem Einparkvorgang ein Abstand zu einem sich vor und/oder hinter dem Fahrzeug befindenden Objekt mittels auf Ultraschall basierenden Abstandssensoren ermittelt wird. Eine Temperatur sowie eine Luftbewegung beeinflussen eine Schallgeschwindigkeit eines ausgesendeten Signals, wodurch ein Abstand falsch erfasst werden kann.in the It is generally known that in a driver assistance system for support a driver during a parking a distance to a before and / or behind the vehicle object by means of ultrasound-based Distance sensors is determined. A temperature and an air movement influence a speed of sound of a transmitted signal, whereby a distance can be detected incorrectly.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges anzugeben, bei dem ein Abstand des Fahrzeuges zu einem sich vor und/oder hinter diesem befindenden Objekt genau ermittelt wird.Of the Invention is based on the object, a method and an apparatus to indicate the operation of a driver assistance system of a vehicle, in which a distance of the vehicle to a front and / or behind This object is accurately determined.
Die Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die im Anspruch 1 und hinsichtlich der Vorrichtung durch die im Anspruch 2 angegebenen Merkmale gelöst.The The object is achieved according to the invention the method by the in claim 1 and in terms of the device solved by the features specified in claim 2.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Further developments of the invention are the subject of the dependent claims.
Ein erfindungsgemäßes Verfahren zum Betrieb eines Fahrerassistenzsystems eines Fahrzeuges sieht vor, dass zumindest ein Abstand zu einem vor dem Fahrzeug befindlichen Objekt erfasst wird, und der erfasste Abstand optisch und/oder akustisch an einen Fahrzeugführer des Fahrzeuges ausgegeben wird. Erfindungsgemäß wird der erfasste Abstand in einem Nahbereich des Fahrzeuges zu dem Objekt anhand einer erfassten Drehbewegung mindestens eines Fahrzeugrades präzisiert.One inventive method sees to the operation of a driver assistance system of a vehicle that at least a distance to a vehicle in front of the vehicle Object is detected, and the detected distance optically and / or acoustically a driver of the vehicle is issued. According to the invention, the detected distance in a vicinity of the vehicle to the object based on a detected Rotational movement of at least one vehicle wheel specified.
