Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Sensoranordnung für ein Fahrzeug und ein verbessertes Fahrzeug anzugeben.The invention is based on the object of specifying a comparison with the prior art improved sensor arrangement for a vehicle and an improved vehicle.
Hinsichtlich der Sensoranordnung wird die Aufgabe durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich des Fahrzeugs durch die im Anspruch 4 angegebenen Merkmale gelöst.With regard to the 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 Sensoranordnung für ein Fahrzeug umfasst mehrere Radarsensoren.The sensor arrangement for a vehicle comprises a plurality of radar sensors.
Erfindungsgemäß ist zumindest eine zentrale Recheneinheit zur Auswertung mittels der Radarsensoren erfasster Daten vorgesehen, die Radarsensoren weisen unterschiedliche Entfernungsauflösungen auf und zumindest einer der Radarsensoren weist einen schwenkbaren Erfassungsbereich auf.According to the invention, at least one central arithmetic unit is provided for evaluation by means of the data acquired by the radar sensors, the radar sensors have different distance resolutions and at least one of the radar sensors has a pivotable detection area.
Mittels der Sensoranordnung ist eine lückenlose Umgebungserfassung für das Fahrzeug, insbesondere eine so genannte 360°-Umgebungserfassung, realisierbar, wobei ein Erfassungsbereich der Sensoranordnung nicht auf einen Nahbereich beschränkt ist, sondern beispielsweise auch einen Mittel- und Fernbereich abdeckt. Der schwenkbare Erfassungsbereich des zumindest einen Radarsensors, auch als strahlschwenkender Radarsensor bezeichnet, ermöglicht dabei, dass die lückenlose Erfassung der Umgebung des Fahrzeugs dabei auch an nicht rechtwinklig verlaufenden Straßenkreuzungen möglich ist.By means of the sensor arrangement, a complete environmental detection for the vehicle, in particular a so-called 360 ° environmental detection, realized, wherein a detection range of the sensor array is not limited to a near area, but for example, also covers a middle and long range. The pivotable detection range of the at least one radar sensor, also referred to as a beam-swiveling radar sensor, makes it possible that the complete detection of the surroundings of the vehicle is also possible at non-right-angled road intersections.
Aufgrund der zentralisierten Anordnung der zumindest einen Recheneinheit wird eine Reduzierung einer Leistungsaufnahme der Radarsensoren erzielt, woraus eine verringerte Wärmeabgabe derselben resultiert. Weiterhin sind Abmessungen der Radarsensoren verringert, wodurch ein erforderlicher Bauraum der Radarsensoren verringert ist. Weiterhin wird eine Adressierung der Sensoranordnung, beispielsweise in einem Datenbussystem, signifikant vereinfacht und eine Datenlast ist reduziert. Hieraus ergibt sich eine vereinfachte Integration der Radarsensoren, insbesondere eine vereinfachte Fahrzeugintegration. Weiterhin kann eine Umgebungserfassung mittels der Sensoranordnung verbessert werden, da eine geringere Limitierung von Rechenressourcen vorliegt.Due to the centralized arrangement of the at least one arithmetic unit, a reduction in power consumption of the radar sensors is achieved, resulting in a reduced heat output thereof. Furthermore, dimensions of the radar sensors are reduced, whereby a required space of the radar sensors is reduced. Furthermore, an addressing of the sensor arrangement, for example in a data bus system, is significantly simplified and a data load is reduced. This results in a simplified integration of the radar sensors, in particular a simplified vehicle integration. Furthermore, an environmental detection can be improved by means of the sensor arrangement, since there is a lower limitation of computing resources.
Ferner wird durch die zentralisierte Anordnung eine vereinfachte Verbesserung und Anpassung einer Signal- und Datenverarbeitung ermöglicht, da lediglich eine Anpassung der zumindest einen zentralen Recheneinheit und nicht Anpassungen mehrerer, jeweils einem Radarsensor zugeordneter und in die Radarsensoren integrierter Recheneinheiten erforderlich ist.Furthermore, a simplified improvement and adaptation of a signal and data processing is made possible by the centralized arrangement, since only an adaptation of the at least one central processing unit and not adjustments of several, each a radar sensor associated and integrated into the radar sensors arithmetic units is required.
Weiterhin zeichnet sich die Sensoranordnung durch eine erhöhte Robustheit und eine erhöhte Verfügbarkeit einer Sensorinformation und einer Darstellung der Umgebung aus. Ferner sind moderne Signalauswerteverfahren, welche beispielsweise auf einem Maschinenlernen und/oder Musterverstehen basieren, einsetzbar.Furthermore, the sensor arrangement is characterized by an increased robustness and an increased availability of sensor information and a representation of the environment. Furthermore, modern signal evaluation methods based on, for example, machine learning and / or pattern understanding can be used.
