Zur Unterstützung eines Kraftfahrers beim Führen eines Kraftfahrzeuges ist es bekannt, diesen mit gemessenen Informationen über beispielsweise einen Abstand zu anderen Fahrzeugen oder Hindernissen zu versorgen.To assist a driver in driving a motor vehicle, it is known this with measured information about, for example, a distance from others To supply vehicles or obstacles.
So ist es aus der DE 36 22 091 A1 bekannt, Sensoren in Blinkergehäusen eines Kraftfahrzeugs vorzusehen, welche bei einer Blinkerbetätigung aktiviert werden und einen rückwärtigen und ggf. einen voraus liegenden Bereich überwachen und beim Spurwechsel vor anderen Fahrzeugen in den überwachten Bereichen warnen.It is known from DE 36 22 091 A1, sensors in a turn signal housing To provide motor vehicle, which are activated when a turn signal is activated and a rear and, if necessary, monitor an area ahead and when changing lanes warn of other vehicles in the monitored areas.
Aus der DE 40 05 444 A1 ist ein Verfahren und eine Vorrichtung zur Unterstützung eines Kraftfahrers bei einem Fahrspurwechsel bekannt. Bei dem Verfahren zum Unterstützen des Kraftfahrers bei seiner Entscheidungsfindung bezüglich eines Fahrspurwechsels seines Kraftfahrzeuges ist vorgesehen, relevante Daten zum nachfolgenden Verkehr zu messen wie Abstand und Relativgeschwindigkeit. Zu diesem Zweck ist in einem Heckbereich des Kraftfahrzeugs ein nach hinten gerichtetes Entfernungsmeßgerät vorgesehen.DE 40 05 444 A1 describes a method and a device for supporting a Motorist known when changing lanes. In the process of supporting the Driver in making a decision about changing his lane Motor vehicle is intended to measure relevant data on subsequent traffic like distance and relative speed. For this purpose, the rear area of the Motor vehicle provided a rear-facing distance measuring device.
Aus dem Artikel "Projected system for volume cars", Automotive Engineer, Band 21, April/Mai 1996, Seite 39 ist ein System bekannt, bei dem eine automatische Abstandsregulierung eines Kraftfahrzeugs zu einem vorausfahrenden Kraftfahrzeug erfolgt, wobei an einem Kühlergrill ein Abstandssensor angeordnet ist. Dieser Abstandssensor detektiert den Abstand zu einem vorausfahrenden Fahrzeug und eine Steuerelektronik regelt über Drosselklappe und Bremse die Geschwindigkeit, so daß automatisch einem vorausfahrenden Fahrzeug mit dessen Geschwindigkeit gefolgt wird. From the article "Projected system for volume cars", Automotive Engineer, Volume 21, April / May 1996, page 39, a system is known in which an automatic Distance regulation of a motor vehicle to a preceding motor vehicle takes place, a distance sensor being arranged on a radiator grille. This distance sensor detects the distance to a vehicle in front and controls the control electronics via throttle and brake the speed, so that automatically one vehicle in front is followed at its speed.
Diese bekannten Anordnungen von Sensoren am Kühlergrill, im Blinkergehäuse oder im Heckbereich des Kraftfahrzeuges sind jedoch dahingehend nachteilig, daß der vom Sensor erfaßte Raumwinkel nicht demjenigen Raumwinkel entspricht, den ein Kraftfahrer mit seinen Augen erfaßt. Dies liegt vor allem daran, daß sich die Sensoren an Orten am Kraftfahrzeug befinden, welcher vom Ort der Augen des Kraftfahrers stark beabstandet ist.These known arrangements of sensors on the grille, in the turn signal housing or in Rear area of the motor vehicle are disadvantageous in that the sensor detected solid angle does not correspond to the solid angle that a driver with his Eyes grasped. This is mainly due to the fact that the sensors are located at locations on the motor vehicle are located, which is strongly spaced from the location of the driver's eyes.
Aus der EP 0 617 296 ist es bekannt, einen Sensor an einer Rückseite eines Innenrückspiegels eines Kraftfahrzeuges vorzusehen. Diese Anordnung hat jedoch den Nachteil, daß der Sensor durch eine Frontscheibe des Fahrzeugs hindurch wirken muß, so daß einerseits bei der Auswahl des Sensortypes große Einschränkungen vorhanden sind und andererseits Verschmutzungen oder Beläge, wie beispielsweise Kondenswasser oder Frost, auf der Frontscheibe die Funktionssicherheit des Sensors beeinträchtigen.From EP 0 617 296 it is known to mount a sensor on a rear side To provide interior rearview mirror of a motor vehicle. However, this arrangement has the Disadvantage that the sensor must act through a front window of the vehicle, so that, on the one hand, there are great restrictions when selecting the sensor type and on the other hand dirt or deposits, such as condensed water or Frost, on the front screen impair the functional safety of the sensor.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Kraftfahrzeug der oben genannten Art zur Verfügung zu stellen, bei dem ein vorhandenes Bauteil als Einbauort für Abstandssensoren genutzt wird, wobei die oben genannten Nachteile überwunden werden.The present invention is therefore based on the object of a motor vehicle of the above to provide the type mentioned, in which an existing component as an installation location for Distance sensors is used, whereby the disadvantages mentioned above are overcome.
Diese Aufgabe wird erfindungsgemäß durch ein Kraftfahrzeug mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a motor vehicle with marked features solved. Advantageous embodiments of the invention are in the dependent claims specified.
Dazu ist es erfindungsgemäß vorgesehen, daß an wenigstens einem Außenrückspiegel des Kraftfahrzeuges zumindest ein Abstandssensor vorgesehen ist.For this purpose, it is provided according to the invention that on at least one exterior rear view mirror Motor vehicle at least one distance sensor is provided.
Je nach Art und Einbauort des zumindestens einen Abstandssensors kann der Abstandssensor zur Überwachung des Bereichs in Fahrtrichtung des Kraftfahrzeuges, des Seitenraums, beispielsweise des "toten Winkels", des Rückraums des Kraftfahrzeuges bei Abbiege- oder Überholvorgängen, eines Fahrbahnbereichs oder auch des Innenraums des Kraftfahrzeuges genutzt werden.Depending on the type and location of the at least one distance sensor, the Distance sensor for monitoring the area in the direction of travel of the motor vehicle, the Side space, for example the "blind spot", the rear space of the motor vehicle Turning or overtaking, a lane area or the interior of the Motor vehicle are used.
Als Abstandssensor können je nach Verwendungsart bevorzugt Infrarot-, Radiowellen-, Laser- oder Radarsensoren oder Kameras eingesetzt werden. Auch Kombinationen dieser Sensoren sind denkbar. Depending on the type of use, infrared, radio wave, Laser or radar sensors or cameras are used. Combinations of these too Sensors are conceivable.
Der erfindungsgemäße Einbauort des zumindest einen Abstandssensors hat den Vorteil, daß der Abstandssensor durch seine räumliche Nähe zu den Augen eines Kraftfahrzeuges nahezu den gleichen bzw. einen größeren Raumwinkel abdeckt, wie diese. Außerdem ist ein Kraftfahrzeug mit einem solchen Abstandssensor auf einfache Weise nachrüstbar.The installation location of the at least one distance sensor according to the invention has the advantage that the distance sensor due to its spatial proximity to the eyes of a motor vehicle covers almost the same or a larger solid angle as this. In addition, is a Motor vehicle can be easily retrofitted with such a distance sensor.
Für eine Weiterverarbeitung eines Sensorsignales zum Erhalten gewünschter und für den Kraftfahrer wichtiger Informationen ist eine Zentraleinheit vorgesehen, welche mit dem Sensor verbunden ist und ein Sensorsignal auswertet.For further processing of a sensor signal to obtain the desired and for the A central unit is provided for drivers of important information Sensor is connected and evaluates a sensor signal.
Eine zusätzliche Unterstützung des Kraftfahrers und eine Verbesserung der Sicherheit wird dadurch erzielt, daß der aus dem Sensorsignal ermittelte Umgebungszustand für das Kraftfahrzeug durch eine Warneinrichtung wiedergebbar ist. Die Warneinrichtung kann dabei eine optische Anzeigeeinrichtung und/oder auch eine akustische Warneinrichtung sein.An additional support for the driver and an improvement in safety will achieved in that the ambient condition determined from the sensor signal for the Motor vehicle can be reproduced by a warning device. The warning device can an optical display device and / or an acoustic warning device.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben. Die zugehörigen Zeichnungen zeigen:The invention is described in more detail below on the basis of exemplary embodiments. The associated drawings show:
Fig. 1 eine bevorzugte Ausführungsform des erfindungsgemäßen Kraftfahrzeuges mit einem in Fahrtrichtung ausgerichteten Abstandssensor, Fig. 1 a preferred embodiment of the vehicle according to the invention with an aligned in the direction of travel distance sensor,

Fig. 3 shows a preferred embodiment of the vehicle according to the invention be monitored with a left side portion of the vehicle distance sensor.
Das in Fig. 1 dargestellte Kraftfahrzeug 10 umfaßt zwei Außenrückspiegel 12 und 14, welche an einer Karosserie 16 des Kraftfahrzeugs 10 befestigt sind. An jedem Außenrückspiegeln 12 und 14 ist ein Abstandssensor 18 und 20 angeordnet und in Fahrtrichtung 22 ausgerichtet. Die Abstandssensoren 18, 20 sind beispielsweise auf ein Gehäuse der Außenrückspiegel 12, 14 aufgesetzt oder in dieses integriert. The motor vehicle 10 shown in FIG. 1 comprises two exterior rear-view mirrors 12 and 14 which are fastened to a body 16 of the motor vehicle 10 . A distance sensor 18 and 20 is arranged on each exterior rear-view mirror 12 and 14 and aligned in the direction of travel 22 . The distance sensors 18 , 20 are, for example, placed on a housing of the exterior rear-view mirrors 12 , 14 or integrated into this.
Jeder Abstandssensor 18 und 20 deckt einen Winkelbereich 24 und 26 ab, in dem vorausfahrende Fahrzeuge detektiert und der Relativabstand zum Fahrzeug 10 gemessen wird. Der Abstandssensor 18 erfaßt so Fahrzeuge die auf derselben Fahrspur wie das Fahrzeug 10 fahren und auch Fahrzeuge die auf einer Fahrspur in Fahrtrichtung 22 links vom Fahrzeug 10 voraus fahren. Der Abstandssensor 20 erfaßt Fahrzeuge die auf derselben Fahrspur wie das Fahrzeug 10 fahren und zusätzlich auch Fahrzeuge die auf einer Fahrspur in Fahrtrichtung 22 rechts vom Fahrzeug 10 voraus fahren.Each distance sensor 18 and 20 covers an angular range 24 and 26 in which vehicles in front are detected and the relative distance to vehicle 10 is measured. The distance sensor 18 thus detects vehicles that are traveling in the same lane as the vehicle 10 and also vehicles that are driving in a lane in the direction of travel 22 to the left of the vehicle 10 . The distance sensor 20 detects vehicles which are traveling in the same lane as the vehicle 10 and additionally also vehicles which are driving in a lane in the direction of travel 22 to the right of the vehicle 10 .
Auf diese Weise werden einem Kraftfahrer Informationen über den Abstand zu vorausfahrenden Fahrzeugen zur Verfügung gestellt. Dazu ist beispielsweise, wie in Fig. 2 dargestellt, eine Zentraleinheit 28 vorgesehen, welche mit dem Abstandssensor 18 verbunden ist. Diese Darstellung ist lediglich beispielhaft und dient zu Erläuterung der Erfindung. Die Zentraleinheit ist vorzugsweise zusätzlich auch mit dem Abstandssensor 20 verbunden oder es ist eine zweite Zentraleinheit vorgesehen und mit dem Abstandssensor 20 verbunden. Die Zentraleinheit 28 empfängt ein Sensorsignal und wertet dieses aus, d. h. berechnet den Abstand zu einem detektierten und vorausfahrenden Fahrzeug.In this way, a driver is provided with information about the distance to vehicles in front. For this purpose, as shown in FIG. 2, a central unit 28 is provided, for example, which is connected to the distance sensor 18 . This illustration is only exemplary and serves to explain the invention. The central unit is preferably also additionally connected to the distance sensor 20 or a second central unit is provided and connected to the distance sensor 20 . The central unit 28 receives a sensor signal and evaluates it, ie calculates the distance to a detected and preceding vehicle.
Diese Information über den Abstand wird dann beispielsweise von der Zentraleinheit 28 dem Kraftfahrer über eine Anzeigevorrichtung 30 zur Verfügung gestellt, so daß der Fahrer diese Information beim Lenken des Kraftfahrzeuges 10 berücksichtigen und ggf. einen beispielsweise zu geringen Abstand zu einem vorausfahrenden Fahrzeug entsprechend korrigiert. Gleichzeitig macht die Zentraleinheit 10 den Kraftfahrer beispielsweise über einen Lautsprecher 32 und/oder eine Warnlampe auf einen zu geringen Abstand zu einem vorausfahrenden Fahrzeug aufmerksam.This information about the distance is then made available, for example, by the central unit 28 to the driver via a display device 30 , so that the driver takes this information into account when steering the motor vehicle 10 and, if necessary, corrects a distance that is too short, for example, from a preceding vehicle. At the same time, the central unit 10 alerts the driver, for example, via a loudspeaker 32 and / or a warning lamp to an insufficient distance from a vehicle in front.
Ferner greift die Zentraleinheit für eine vorbestimmte Abstandkorrektur direkt ein, beispielsweise durch Ansteuern einer Drosselklappe 34 einer Brennkraftmaschine 36 und/oder einer Bremse 38 des Kraftfahrzeuges 10. Hierbei kann die Zentraleinheit 28 beispielsweise eine Notbremsung automatisch einleiten und durchführen, wenn sich aus dem Sensorsignal eine drohende Kollision mit einem vorausfahrenden Fahrzeug ergibt oder das Sensorsignal ein plötzlich auftretendes Hindernis auf der Fahrbahn, wie beispielsweise ein Reh oder einen umgestürzten Baum, anzeigt. Furthermore, the central unit intervenes directly for a predetermined distance correction, for example by actuating a throttle valve 34 of an internal combustion engine 36 and / or a brake 38 of the motor vehicle 10. Here, the central unit 28 can automatically initiate and carry out emergency braking, for example, if an impending sensor signal results Collision with a vehicle in front results or the sensor signal indicates a sudden obstacle on the road, such as a deer or a fallen tree.
Mittels der gleichzeitigen Steuerung von Drosselklappe 34 und Bremse 38 kann die Zentraleinheit 28 ferner einen gewünschten vorbestimmten Abstand zu einem vorausfahrenden Fahrzeug konstant aufrechterhalten, ohne daß der Kraftfahrer dies durch ständiges Betätigen von Gaspedal und ggf. Bremse tun muß. Der Kraftfahrer ist so von der Aufgabe der Abstandsüberwachung im wesentlichen befreit und kann seine Aufmerksamkeit mehr dem Verkehrsgeschehen widmen. Dies erhöht die Sicherheit im Straßenverkehr erheblich und reduziert die Erschöpfung des Kraftfahrers nach dem Fahren einer längeren Strecke.By means of the simultaneous control of throttle valve 34 and brake 38 , the central unit 28 can also maintain a desired predetermined distance from a vehicle in front constantly, without the driver having to do this by constantly actuating the accelerator pedal and possibly the brake. The driver is essentially freed from the task of distance monitoring and can devote his attention more to the traffic situation. This significantly increases road safety and reduces driver fatigue after driving a long distance.
In Fig. 3 trägt der Außenrückspiegel 12 einen Abstandssensor 18, der so ausgerichtet ist, daß der Abstandssensor den vollständigen, linken Seitenbereich 40 des Kraftfahrzeuges überwacht. Dazu ist der Abstandssensor 18 beispielsweise als Laserscanner ausgebildet, mit dem es möglich ist, einen Überwachungsbereich bis zu 360° zu beobachten. Durch die Überwachung des Seitenbereichs 40 und damit des toten Winkels wird der Fahrzeugführer bei Abbiege- oder Überholvorgängen aktiv unterstützt. In FIG. 3, the exterior rearview mirror 12 carries a distance sensor 18 , which is oriented in such a way that the distance sensor monitors the complete, left side area 40 of the motor vehicle. For this purpose, the distance sensor 18 is designed, for example, as a laser scanner, with which it is possible to observe a monitoring area of up to 360 °. By monitoring the side area 40 and thus the blind spot, the vehicle driver is actively supported in turning or overtaking processes.
