Abstract
Description
In Kraftfahrzeugen werden optische Sensoren zur Erfassung der Fahrzeugumgebung und des Fahrzeuginnenraums eingesetzt. Die Informationen über relevante Objekte im und außerhalb des Fahrzeugs werden in Fahrerassistenzsystemen in Fahrhilfen umgesetzt, so dass Unfälle vermieden werden, oder wenn das nicht möglich ist, die Schwere des Unfalls und die Unfallfolgen gemildert werden. Zu den Fahrerassistenzsystemen zählen u.a. ACC (Adaptive Cruise Control), Stop & Go – System, Pre-Crash – System, Sitzbelegungserkennung, Fußgängerkollisionsschutz und die Einparkhilfe. Durch die wiederholte Bestimmung des Abstands eines erfassten Objekts zum Fahrzeug kann die Geschwindigkeit des Fahrzeugs den aktuellen Verkehrsbedingungen angepasst werden. Bevorstehende unausweichliche Kollisionen werden erkannt und schadensmindernde Maßnahmen eingeleitet. Zusätzlich ist es von Vorteil die Objekte in der Fahrzeugumgebung zu identifizieren und zu klassifizieren. Die zu ergreifenden Maßnahmen bei einer bevorstehenden Kollision hängen davon ab, ob sich der Zusammenstoß mit einem Fußgänger, einer Leitplanke oder einem Lastkraftwagen ereignet; z.B. wird bei einer Kollision eines Fußgängers mit dem Fahrzeug die Motorhaube etwas geöffnet, um bei einem Aufprall des Fußgängers die Knautschzone zu vergrößern.In Motor vehicles are optical sensors for detecting the vehicle environment and the vehicle interior used. The information about relevant Objects inside and outside of the vehicle are implemented in driving assistance systems in driver assistance systems, so that accidents avoided, or if that is not possible, the severity of the problem Accident and the consequences of accidents are mitigated. To the driver assistance systems counting et al ACC (Adaptive Cruise Control), Stop & Go System, Pre-Crash System, Seat occupancy detection, pedestrian collision protection and the parking aid. By repeatedly determining the distance a detected object to the vehicle may be the speed of the vehicle adapted to the current traffic conditions. Upcoming Inescapable collisions are detected and damage-reducing measures initiated. additionally it is advantageous to identify the objects in the vehicle environment and to classify. The action to be taken in the case of an impending Collision depend on it whether the clash with a pedestrian, one Guardrail or a truck occurs; e.g. is at a Collision of a pedestrian with The bonnet of the vehicle is slightly opened in an impact pedestrian's crumple zone to enlarge.
Es
gibt bereits Ansätze
zur dreidimensionalen Objekterkennung, die auch die Abstandsinformation
vom Fahrzeug zum Objekt beinhaltet, z.B. wurde von der Firma Siemens
eine Stereokamera entwickelt und die Firma IBEO entwickelte in Kooperation mit
der Firma Hella einen Laserscanner, der separate Winkelbereiche
von 0,25° bis
1 ° in der
Fahrzeugumgebung nacheinander abtastet und die Laufzeit eines Lichtpulses
aufnimmt. Die beschriebenen hochauflösenden 3D-Systeme sind technisch
aufwändig
und kostenintensiv. Auf der anderen Seite gibt es Konzepte, die
mehrere Empfangskanäle
(2-3) vorsehen. Durch die Kanaltrennung kann zusätzlich zur Laufzeitmessung
eine Angabe zur Objektposition gemacht werden, eine Beschreibung
findet sich u.a. in
Es ist daher eine Aufgabe der hier vorliegenden Erfindung, Objekte in der Umgebung und im Innenraum eines Kraftfahrzeugs zu erfassen.It is therefore an object of the present invention, objects to capture in the environment and in the interior of a motor vehicle.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Vorrichtung mit den in Anspruch 1 beschriebenen Merkmalen. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.These The object is achieved by a device having the features described in claim 1. Advantageous developments can be found in the dependent claims.
Erfindungsgemäß wurde erkannt, dass eine kostengünstige Vorrichtung zur Erfassung von Objekten durch Strahlungsdetektoren realisiert werden kann, wobei die Strahlungsdetektoren in mindestens zwei parallelen, beabstandeten Streifen auf einem Träger angeordnet sind. Dies bietet den Vorteil, dass der Winkelerfassungsbereich der Vorrichtung vergrößert werden kann, ohne die strahlungsaktive Fläche und Anzahl der Bildpixel in gleichem Maß zu erhöhen. Da Strahlungsdetektoren und Auswerteelektronik durch die reduzierte Anzahl von Bildpixeln eingespart werden, trägt dieser Ansatz zur Kosteneffizienz bei. Ist ein Linsensystem zur Bündelung des einfallenden Lichts auf die Strahlungsdetektoren vorgesehen, so ist durch die beabstandet angeordneten Streifen eine weniger starke Fokussierung der Lichtstrahlen notwendig als bei einer direkt benachbarten Anordnung der Streifen, und es kann eine lichtstärkere Optik eingesetzt werden.According to the invention was recognized that a cost-effective Device for detecting objects by radiation detectors can be realized, wherein the radiation detectors in at least two parallel, spaced strips are arranged on a support. This offers the advantage that the angle detection range of the device can be increased can, without the radiative area and number of image pixels to the same extent increase. Because radiation detectors and transmitter through the reduced Number of image pixels can be saved, this approach contributes to cost efficiency. Is a lens system for bundling the incident light is provided on the radiation detectors, so is by the spaced-apart strips one less strong focus of the light beams necessary than in a direct adjacent arrangement of the strips, and it can be a brighter look be used.
Vorzugsweise sind die Strahlungsdetektor-Streifen horizontal und/oder vertikal angeordnet, in Abhängigkeit von den Erfordernissen der zu erfassenden Umgebung. Eine erhöhte vertikale Bildauflösung wird benötigt, wenn z.B. ein Bordstein eines Fußwegs von einer Mauer unterschieden werden soll. Für die Aufnahme einer stark inhomogen Umgebung, z.B. des Fahrzeuginnenraums, ist die Anordnung von horizontalen und vertikalen Streifen vorteilhaft.Preferably The radiation detector strips are horizontal and / or vertical arranged, depending from the requirements of the environment to be detected. An elevated vertical resolution is required, if e.g. a curb of a footpath distinguished from a wall shall be. For the inclusion of a highly inhomogeneous environment, e.g. of the vehicle interior, the arrangement of horizontal and vertical strips is advantageous.
Als vorteilhafte Strahlungsdetektoren sind PIN-Photodioden vorgesehen, die schnell, kompakt und kostengünstig sind. Vorzugsweise wird die Vorrichtung zur Erfassung von Objekten kombiniert mit einer gepulsten Strahlungsquelle betrieben, durch Pulslaufzeitmessung werden die Objekte dreidimensional abgebildet. Diese Ausführung ist besonders für die Erkennung einer bevorstehenden Kollision geeignet.When advantageous radiation detectors are provided PIN photodiodes, the fast, compact and cost-effective are. Preferably, the device is for detecting objects operated in combination with a pulsed radiation source, by pulse transit time measurement the objects are displayed in three dimensions. This design is especially for the detection of an impending collision suitable.
Vorzugsweise ist pro Bildpixel ein Strahlungsdetektor und eine zugehörige Einheit zur Signalverarbeitung vorgesehen, wobei die Einheit das analoge Signal verstärkt und digitalisiert. Vorzugsweise sind der Strahlungsdetektor und die zugehörige Signalverarbeitungseinheit benachbart auf dem Träger angeordnet, um eine optimale Pixeltrennung zu erreichen.Preferably is a radiation detector and an associated unit per image pixel provided for signal processing, wherein the unit of the analog Signal amplified and digitized. Preferably, the radiation detector and the associated signal processing unit adjacent to the carrier arranged to achieve optimal pixel separation.
In einer vorteilhaften Ausführungsform wird die zentrale Signalauswertung für alle Pixel in einer separaten Einheit ausgeführt. Aus Gründen der Kompaktheit Kosteneffizienz ist es vorteilhaft die Strahlungsdetektoren, sowie die Signalverarbeitungs- und Signalauswertungseinheiten auf einem Halbleitersubstrat anzuordnen. Vorzugsweise sind Kraftfahrzeuge mit der beschriebenen Vorrichtung zur Erfassung von Objekten ausgestattet, wobei die Bildinformationen im Kraftfahrzeug durch ein Fahrerassistenzsystem in Fahrhilfen umgesetzt wird.In an advantageous embodiment, the central signal evaluation is carried out for all pixels in a separate unit. For reasons of compactness cost-efficiency, it is advantageous to arrange the radiation detectors, as well as the signal processing and signal processing units on a semiconductor substrate.
