Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The The object is solved by the features of claim 1.
Die erfindungsgemäße Klassifikationseinrichtung für Fahrzeuge vermag die Länge eines Fahrzeugs, die Zahl der Räder des Fahrzeugs und damit der Achsen und deren Verteilung über die Länge des Fahrzeugs zu ermitteln. Sie ist mit einer neben einer Fahrbahn angeordneten Geschwindigkeitsmesseinrichtung für ein rotierendes auf der Fahrbahn rollendes Rad ausgerüstet, welche einen Radarsender, einen Radarempfänger, eine Radar-Sende- und -Empfangsantenne und eine Auswerteeinrichtung für empfangene reflektierte Radarsignale umfasst, bei der die Strahlungskeule der Radar-Sende- und Empfangsantenne im Wesentlichen auf die Nabe des Rades und unter einem Winkel zwischen 0° und 180° zur Bewegungsrichtung des rollenden Rades ausgerichtet ist.The Classification device according to the invention for vehicles can the length of a vehicle, the number of wheels of the vehicle and thus the axes and their distribution over the Length of the vehicle to investigate. It is arranged with one next to a roadway Speed measuring device for a rotating on the road equipped with rolling wheel, which a radar transmitter, a radar receiver, a radar transmitting and Receiving antenna and an evaluation device for received reflected radar signals comprising, at the radiation lobe of the radar transmitting and receiving antenna essentially on the hub of the wheel and at an angle between 0 ° and 180 ° to the direction of movement is aligned with the rolling wheel.
Die Geschwindigkeitsmesseinrichtung vermag mit einer Radar-Geschwindigkeitsmessung die Länge eines Fahrzeugs, die Zahl der Räder und damit der Achsen des Fahrzeugs und deren räumliche Verteilung über die Länge des Fahrzeugs zu ermitteln, wobei diese auch den Zeitpunkt des Beginns der Messung bestimmt. Die Fahrzeugklasse wird vorteilhafterweise nur an Hand der Auswertung des Radarechosignalprofils erkannt.The Speed measuring device can with a radar speed measurement the length of a vehicle, the number of wheels and thus the axes of the vehicle and their spatial distribution over the Length of the Vehicle to determine, this also the time of the beginning determined the measurement. The vehicle class is advantageously only recognized by the evaluation of the radar echo signal profile.
Bei einer bevorzugten Ausführungsform der Klassifikationseinrichtung ist die Strahlungskeule der Radar-Sendeantenne unter einem Winkel von 30° bis 60°, insbesondere aber von 45° zur Bewegungsrichtung des rollenden Rades ausgerichtet. Die Schrägstellung der Strahlungskeule erlaubt eine feine Auflösung des Messergebnisses, da sich das Rad länger in der Strahlungskeule befindet.at a preferred embodiment the classification device is the radiation lobe of the radar transmission antenna at an angle of 30 ° to 60 °, in particular but from 45 ° to Direction of movement of the rolling wheel aligned. The inclination the radiation lobe allows a fine resolution of the measurement result, since the bike is longer in the radiation lobe is located.
Bei der erfindungsgemäßen Klassifikationseinrichtung erfolgt eine Erkennung des auf einer Fahrbahn rollenden Rades mittels einer Radar-Geschwindigkeitsmessung, wobei die Fortbewegungsgeschwindigkeit des Fahrzeugs – verkörpert durch die Nabe des Rades – auf der Fahrbahn und die Umfangsgeschwindigkeit einzelner Umfangsabschnitte des Rades erfasst und zueinander in Beziehung gesetzt werden.at the classification device according to the invention a detection of rolling on a road wheel by means of a radar speed measurement, the speed of travel of the vehicle - embodied by the Hub of the wheel - on the roadway and the peripheral speed of individual peripheral sections of the Rades recorded and related to each other.
Vorzugsweise wird dabei die Fortbewegungsgeschwindigkeit des Fahrzeugs, die Fortbewegungsgeschwindigkeit des Umfangsabschnitts, der dem Berührungspunkt des Rades mit der Fahrbahn gegenüber liegt und die Fortbewegungsgeschwindigkeit des Umfangsabschnitts am Berührungspunkt mit einander verglichen.Preferably is the speed of movement of the vehicle, the speed of movement the peripheral portion of the contact point of the wheel with the Roadway opposite is and the travel speed of the peripheral portion at the point of contact compared with each other.
Die
Erfindung geht dabei von der Überlegung aus,
dass der Umfangsabschnitt des Rades, der dem Berührungspunkt des Rades mit der
Fahrbahn gegenüber
liegt, gegenüber
dem bewegten System schneller ist als das bewegte System. Der Umfangsabschnitt
am Berührungspunkt
des Rades mit der Fahrbahn ist hingegen am Berührungspunkt langsamer als das
bewegte System. Die Radar-Geschwindigkeitsmesseinrichtung erzeugt
dann ein in
Die Zahl der Achsen des vorbeifahrenden Fahrzeugs wird aus der Zahl unmittelbar aufeinander folgender Geschwindigkeitsmaxima und -Minima ermittelt.The Number of axles of the passing vehicle will be out of the number immediately successive maximum velocities and minima determined.
In einer bevorzugten Weiterbildung der Erfindung erkennt die Klassifikationseinrichtung aus dem Vorhandensein eines Radarsignalminimums ein Fahrzeuggespann.In A preferred embodiment of the invention recognizes the classification device from the presence of a radar signal minimum, a vehicle combination.

Durch die gemeinsame Auswertung der Fahrzeuglänge und der Verteilung der Signalmaxima über die Länge des jeweiligen Fahrzeugs ist bei der Straßenverkehrsordnung entsprechenden Fahrzeugen eine Klassifizierung durch die vorliegende Erfindung leicht möglich. Nicht einmal ein Defekt an einem Fahrzeug wie etwa eine defekte Auspuffanlage kann zu einer Fehlinterpretation des Signalprofils führen. Ein weiterer Vorteil ist die schnelle Durchführbarkeit der Klassifizierung.By the joint evaluation of the vehicle length and the distribution of the Signal maxima over the length of the respective vehicle is corresponding to the road traffic regulations Vehicles a classification by the present invention easily possible. Not even a defect on a vehicle such as a broken one Exhaust system can lead to a misinterpretation of the signal profile to lead. One Another advantage is the rapid implementation of the classification.
