Description
Die Erfindung betrifft eine Radarsensoranordnung zur Umgebungsüberwachung für ein Fahrzeug mit zumindest einem Radarsensor, der eine Sendeeinheit zur Ausstrahlung von Radarsignalen in zwei Ausstrahlungsbereiche und eine Empfangseinheit zum Empfang von an wenigstens einem Gegenstand innerhalb der Ausstrahlungsbereiche reflektierten Radarsignalen umfasst, wobei eine erste Sendereichweite innerhalb eines ersten Ausstrahlungsbereichs kleiner als eine zweite Sendereichweite innerhalb eines zweiten Ausstrahlungsbereichs ist und Mittelachsen der Ausstrahlungsbereiche um einen vorgegebenen Winkel zueinander verschoben sind.The invention relates to a radar sensor arrangement for environmental monitoring for a vehicle having at least one radar sensor, which comprises a transmitting unit for emitting radar signals in two emission areas and a receiving unit for receiving radar signals reflected at at least one object within the emission areas, wherein a first transmission range within a first emission area is smaller than a second transmission range within a second transmission range and center axes of the transmission ranges are shifted from each other by a predetermined angle.
Die Erfindung betrifft weiterhin ein Fahrzeug mit einer solchen Radarsensoranordnung.The invention further relates to a vehicle having such a radar sensor arrangement.
Die
Der Erfindung liegt die Aufgabe zugrunde, einen gegenüber dem Stand der Technik verbesserte Radarsensoranordnung zur Umgebungsüberwachung für ein Fahrzeug und ein verbessertes Fahrzeug mit einer solchen Radarsensoranordnung anzugeben.The invention has for its object to provide a comparison with the prior art improved radar sensor array for environmental monitoring for a vehicle and an improved vehicle with such a radar sensor array.
Hinsichtlich der Radarsensoranordnung wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich des Fahrzeugs durch die im Anspruch 8 angegebenen Merkmale gelöst.With regard to the radar sensor arrangement, 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.
Die Radarsensoranordnung zur Umgebungsüberwachung für ein Fahrzeug umfasst zumindest einen Radarsensor, der eine Sendeeinheit zur Ausstrahlung von Radarsignalen in zwei Ausstrahlungsbereiche und eine Empfangseinheit zum Empfang von an wenigstens einem Gegenstand innerhalb der Ausstrahlungsbereiche reflektierten Radarsignalen umfasst. Eine erste Sendereichweite innerhalb eines ersten Ausstrahlungsbereichs ist kleiner als eine zweite Sendereichweite innerhalb eines zweiten Ausstrahlungsbereichs und Mittelachsen der Ausstrahlungsbereiche sind um einen vorgegebenen Winkel zueinander verschoben.The radar sensor arrangement for environmental monitoring for a vehicle comprises at least one radar sensor comprising a transmitting unit for emitting radar signals in two emission areas and a receiving unit for receiving radar signals reflected at at least one object within the emission areas. A first transmission range within a first transmission range is smaller than a second transmission range within a second transmission range, and central axes of the transmission ranges are shifted from each other by a predetermined angle.
Erfindungsgemäß ist der Radarsensor mit einer Schaltung gekoppelt, die ein Beamforming-Netzwerk zur Gestaltung einer geometrischen Kontur der Ausstrahlungsbereiche bildet.According to the invention, the radar sensor is coupled to a circuit which forms a beam-forming network for shaping a geometric contour of the emission areas.
Unter einem Beamforming-Netzwerk (im Englischen: beamforming network, kurz: BFN) wird dabei vorliegend eine Schaltung verstanden, welche ein Strahlungsprofil einer Antenne einer beliebig gestalteten geometrischen Kontur anpasst. Das heißt im Sinne der Erfindung, dass mittels der Schaltung die Ausstrahlungsbereiche des Radarsensors an eine vorgegebene geometrische Kontur angepasst werden.A beamforming network (in short: BFN) is understood here to mean a circuit which adapts a radiation profile of an antenna to an arbitrarily designed geometric contour. That is to say in the sense of the invention, that the emission areas of the radar sensor are adapted to a given geometric contour by means of the circuit.
Somit ermöglicht die erfindungsgemäße Radarsensoranordnung in einfacher Weise die Erzeugung von verschiedenen Ausstrahlungsbereichen mit unterschiedlichen Sendereichweiten der Radarsignale. Aufgrund der Verschiebung der Mittelachsen der Ausstrahlungsbereiche um den vorgegebenen Winkel, welche vorzugsweise mit einem konstanten Phasenwinkel mittels einer Speiseleitung erfolgt, ist eine Ausrichtung der Ausstrahlungsbereiche in der Art möglich, dass an einem Fahrzeugheck lediglich zwei der erfindungsgemäßen Radarsensoranordnung zur vollständigen Überwachung eines rückwärtigen Fahrzeugumfeldes erforderlich sind, wobei diese vorzugsweise in einem linken äußeren Bereich am Fahrzeugheck und einem rechten äußeren Bereich am Fahrzeugheck angeordnet sind. Ein Ausstrahlungsbereich eines dritten im mittleren Bereich des Fahrzeughecks angeordneten Radarsensors wird durch die Erweiterung der Ausstrahlungsbereiche der beiden äußeren Radarsensoren erzeugt. Gegenüber aus dem Stand der Technik bekannten Lösungen, welche eine Anordnung von mindestens drei Radarsensoranordnungen erfordern, werden dadurch Material- und Kosteneinsparungen erzielt. Da zur Überwachung des rückwärtigen Fahrzeugumfeldes eine im mittleren Bereich eines Fahrzeughecks angeordnete Radarsensoranordnung nicht erforderlich ist, wird weiterhin in besonders vorteilhafter Weise ein negativer Einfluss einer Anhängekupplung auf die Überwachung mittels der Radarsensoranordnungen vermieden.Thus, the radar sensor arrangement according to the invention enables in a simple manner the generation of different emission ranges with different transmission ranges of the radar signals. Due to the displacement of the central axes of the emission regions by the predetermined angle, which preferably takes place with a constant phase angle by means of a feed line, an alignment of the emission regions is possible in such a way that only two of the radar sensor arrangement according to the invention for complete monitoring of a rear vehicle environment are required at a vehicle rear These are preferably arranged in a left outer region at the rear of the vehicle and a right outer region at the rear of the vehicle. A radiation area of a third radar sensor arranged in the middle region of the vehicle rear is generated by the extension of the radiation areas of the two outer radar sensors. Compared to known from the prior art solutions which require an array of at least three radar sensor arrays, this material and cost savings are achieved. Since a radar sensor arrangement arranged in the middle region of a vehicle rear is not required for monitoring the rear vehicle environment, a negative influence of a trailer coupling on the monitoring by means of the radar sensor arrangements is furthermore avoided in a particularly advantageous manner.
Weiterhin ermöglichen die mittels des Beamforming-Netzwerks erzeugten Ausstrahlungsbereiche mit den unterschiedlichen Sendereichweiten eine zuverlässige Winkelauswertung mit hoher Winkelauflösung und Winkelgenauigkeit, wobei keine mechanische Verschiebung bei den Sensorkomponenten erforderlich ist. Das heißt, neben einer Entfernung ist zusätzlich auch eine exakte Ermittlung eines Winkel des erfassten Gegenstands zu dem Radarsensor ermittelbar, was mittels aus dem Stand der Technik bekannten Radarsensoranordnungen, welche lediglich einen keulenförmigen Haupt-Ausstrahlungsbereich und keulenförmigen Neben-Ausstrahlungsbereich erzeugen, nicht möglich ist. Furthermore, the radiation ranges generated by means of the beam-forming network with the different transmission ranges allow a reliable angle evaluation with high angular resolution and angular accuracy, with no mechanical displacement in the sensor components is required. That is, in addition to a distance, an exact determination of an angle of the detected object to the radar sensor can additionally be determined, which is not possible by means of radar sensor arrangements known from the prior art, which only generate a club-shaped main radiation area and club-shaped secondary radiation area.
Dies ermöglicht bei der Anwendung der Radarsensoranordnung zur Überwachung der rückwärtigen Fahrzeugumgebung, dass mittels des Radarsensors Fahrzeuge erfasst werden können, die sich dem Fahrzeugheck nähern, wobei neben deren Entfernung auch der Winkel zum eigenen Fahrzeug sehr genau erfassbar ist. Somit ist ein Betrieb einer Fahrerassistenzvorrichtung in Abhängigkeit des erfassten Winkels möglich. Ist die Fahrerassistenzvorrichtung beispielsweise als Spurwechselassistent ausgebildet, sind nicht nur Warnungen erzeugbar, sondern aufgrund der Kenntnis des Winkels anhand eines feinfühligen Lenkeingriffs auch ein Schutz des Fahrzeugs vor einer Kollision mit einem schnelleren, auffahrenden Fahrzeug möglich.This allows in the application of the radar sensor arrangement for monitoring the rear vehicle environment that can be detected by means of the radar sensor vehicles approaching the rear of the vehicle, in addition to the distance and the angle to the own vehicle is very accurately detected. Thus, an operation of a driver assistance device in dependence on the detected angle is possible. If the driver assistance device is designed, for example, as a lane change assistant, not only warnings can be generated but, based on the knowledge of the angle based on a sensitive steering intervention, it is also possible to protect the vehicle from a collision with a faster, approaching vehicle.

Alternativ oder zusätzlich bilden die ersten Ausstrahlungsbereiche A11, A12 ein Mittelbereichsradar und die zweiten Ausstrahlungsbereiche A21, A22 ein Fernbereichsradar. Das Fernbereichsradar weist dabei eine Sendereichweite von mehr als 100 m auf.Alternatively or additionally, the first emission regions A1 1 , A1 2 form a mid-range radar and the second emission regions A2 1 , A2 2 form a long-range radar. The long-range radar has a transmission range of more than 100 m.
Die Mittelachsen M11, M21, M12, M22 der Ausstrahlungsbereiche A11, A21, A12, A22 sind um einen vorgegebenen Winkel α1, α2 zueinander verschoben, wobei der Betrag des Winkels α1, α2, weniger als 90° beträgt. Im dargestellten Ausführungsbeispiel betragen die Winkel α1 α2 45°.The center axes M1 1 , M2 1 , M1 2 , M2 2 of the emission areas A1 1 , A2 1 , A1 2 , A2 2 are shifted relative to each other by a predetermined angle α 1 , α 2 , the amount of the angle α 1 , α 2 , less than 90 °. In the illustrated embodiment, the angles α 1 α 2 are 45 °.
Hierzu sind die Radarsensoren
Dadurch, dass die Verschiebung zwischen den ersten Ausstrahlungsbereichen A11, A12 und den jeweils zugehörigen zweiten Ausstrahlungsbereichen A21, A22 um die Winkel α1 α2 der als Beamforming-Netzwerk ausgebildeten Schaltungen
Dabei sind die Ausstrahlungsbereiche A11, A21, A12, A22 jeweils kreiskegelförmig ausgebildet, wobei sich die ersten Ausstrahlungsbereiche A11, A12 durch eine größere Breite auszeichnen. Zu diesem Zweck ist der jeweilige Winkel β zwischen der Mittelachse M11, M12 und einer Mantelfläche der ersten Ausstrahlungsbereiche A11, A12 größer als der jeweilige Winkel γ zwischen der Mittelachse M21, M22 und einer Mantelfläche der zweiten Ausstrahlungsbereiche A21, A22 ist.In this case, the emission regions A1 1 , A2 1 , A1 2 , A2 2 are each formed in a circular cone shape, wherein the first emission regions A1 1 , A1 2 are characterized by a greater width. For this purpose, the respective angle β between the central axis M1 1 , M1 2 and a lateral surface of the first emission regions A1 1 , A1 2 is greater than the respective angle γ between the central axis M2 1 , M2 2 and a lateral surface of the second emission regions A2 1 , A2 is 2 .
Der Winkel β beträgt im dargestellten Ausführungsbeispiel 70° und der Winkel γ 25°.The angle β in the illustrated embodiment is 70 ° and the angle γ 25 °.
Weiterhin überlappen sich die jeweiligen ersten Ausstrahlungsbereiche A11, A12 mit den zugehörigen zweiten Ausstrahlungsbereiche A21, A22. Auch überlappen sich die ersten Ausstrahlungsbereiche A11, A12 untereinander und die zweiten Ausstrahlungsbereiche A21, A22 untereinander, so dass eine Überwachung der vollständigen rückwärtigen Fahrzeugumgebung realisierbar ist.Furthermore, the respective first emission regions A1 1 , A1 2 overlap with the associated second emission regions A2 1 , A2 2 . The first emission regions A1 1 , A1 2 also overlap one another and the second emission regions A2 1 , A2 2 overlap one another, so that it is possible to monitor the complete rear vehicle environment.
