Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Fahrzeug mit mehreren Kameras zur Erfassung eines seitlich neben und seitlich hinter dem Fahrzeug befindlichen Bereichs anzugeben. The invention has for its object to provide a comparison with the prior art improved vehicle with multiple cameras for detecting a laterally adjacent to the side and behind the vehicle area.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Advantageous embodiments of the invention are the subject of the dependent claims.
Das Fahrzeug weist mehrere Bilderfassungseinheiten zur Erfassung eines seitlich neben und seitlich hinter dem Fahrzeug befindlichen Bereichs auf, wobei jeder The vehicle has a plurality of image capture units for detecting a laterally adjacent and laterally behind the vehicle area, each
Bilderfassungseinheit zumindest eine Anzeigeeinheit zugeordnet ist, anhand welcher mittels der zugehörigen Bilderfassungseinheit erfasste Bilder anzeigbar sind. Image acquisition unit is associated with at least one display unit, based on which by means of the associated image detection unit detected images can be displayed.
Erfindungsgemäß umfassen die Bilderfassungseinheiten jeweils zumindest eine According to the invention, the image capture units each comprise at least one
Infrarotkamera, wobei die Infrarotkameras zur Erfassung von naher Infrarotstrahlung und/oder ferner Infrarotstrahlung ausgebildet sind. Infrared camera, wherein the infrared cameras are designed to detect near infrared radiation and / or further infrared radiation.
Dadurch ist es in besonders vorteilhafter Weise möglich, den seitlich neben und seitlich hinter dem Fahrzeug befindlichen Bereich auch bei schlechter Sicht, insbesondere bei Dunkelheit, Nebel und Niederschlägen, bildlich zu erfassen und dem Fahrer des This makes it possible in a particularly advantageous manner, the laterally adjacent to the side and behind the vehicle area even in poor visibility, especially in the dark, fog and rain, to capture and the driver of the image
Fahrzeugs über die Anzeigeeinheiten auszugeben. Somit wird für den Fahrer des Fahrzeugs insbesondere bei Dunkelheit und schlechten Sichtverhältnissen eine verbesserte Sicht gegenüber herkömmlichen Außenspiegeln oder mittels herkömmlicher Kameras ersetzten Außenspiegel erreicht. Auch ist ein Erfassungsbereich der Issue vehicle via the display units. Thus, the driver of the vehicle, especially in the dark and poor visibility improved visibility compared to conventional exterior mirrors or replaced by conventional cameras exterior mirrors is achieved. Also is a coverage of the
Bilderfassungseinheiten in besonders vorteilhafter Weise größer als der eines herkömmlichen Außenspiegels, was zu einer weiteren Verbesserung der Sicht des Fahrers führt. Image capture units in a particularly advantageous manner greater than that of a conventional exterior mirror, resulting in a further improvement of the driver's view.
Aus der Ausbildung der Infrarotkameras zur Erfassung von naher Infrarotstrahlung und/oder ferner Infrarotstrahlung, d. h. als so genannte NIR- und/oder FIR-Kameras, ist insbesondere bei Dunkelheit und eingeschränkten Sichtverhältnissen eine optimierte Sicht für den Fahrer des Fahrzeugs realisierbar, da eine Erfassung von Objekten ohne Wärmeabgabe im näheren Umfeld des Fahrzeugs mittels der NIR-Kameras und/oder eine Erfassung mit hoher Reichweite von Wärme abgebenden Objekten mittels der FIR- Kameras möglich ist. From the training of infrared cameras for detecting near infrared radiation and / or further infrared radiation, ie as so-called NIR and / or FIR cameras, is an optimized view for the driver of the vehicle can be realized, in particular in the dark and in restricted visibility conditions, since detection of objects without heat emission in the immediate surroundings of the vehicle by means of the NIR cameras and / or detection with high range of heat-emitting objects by means of the FIR cameras is possible.
Aufgrund des Ersatzes der herkömmlichen Außenspiegel durch die erfindungsgemäße Kombination aus Bilderfassungseinheiten und Anzeigeeinheiten ist ein verringerter Luftwiderstand bzw. Cw-Wert des Fahrzeugs verringert, woraus eine Verringerung eines Kraftstoffverbrauchs des Fahrzeugs und somit eines Schadstoffausstoßes folgt. Auch die Verringerung des Fahrzeuggewichts infolge des Wegfalls von Außenspiegeln trägt zu einer Verringerung des Kraftstoffverbrauchs und somit zu einer Verringerung des Due to the replacement of the conventional exterior mirrors by the inventive combination of image sensing units and display units, a reduced air resistance or Cw value of the vehicle is reduced, resulting in a reduction in fuel consumption of the vehicle and thus a pollutant emissions follows. Also, the reduction in vehicle weight due to the elimination of exterior mirrors contributes to a reduction in fuel consumption and thus to a reduction of the
Schadstoffausstoßes bei. Zusätzlich zeichnet sich das Fahrzeug aufgrund der Pollutant emissions at. In addition, the vehicle is characterized by the
verbesserten Aerodynamik durch eine verbesserte Aeroakustik aus. Als besonderer Vorteil ergibt sich aus den geringen Abmessungen der Bilderfassungseinheiten gegenüber herkömmlichen Außenspiegeln die Möglichkeit der Verringerung der improved aerodynamics through improved aeroacoustics. As a particular advantage results from the small dimensions of the image acquisition units over conventional exterior mirrors the possibility of reducing the
