Abstract

Device for detecting other vehicles in the rear vision field of a vehicle with at least one rearview mirror (14, 15), a contactless distance measuring device (18) with a range of action limited to a few meters being further provided. The measuring beam thereof is laterally directed towards the overtaking lane so as to have an effective action in the dead rearview field of the rearview mirror or mirrors. If one vehicle is thus detected by the beam, an optical and/or acoustic control device (23), preferably a light diode in the rearview mirror (24) is switched on inside the vehicle.

Description

Vorrichtung zur Erfassung von anderen Fahrzeugen im rückwärtigen Sichtfeld eines FahrzeugsDevice for detecting other vehicles in the rear field of vision of a vehicle
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung nach der Gattung des Hauptanspruchs. Zur Erfassung solcher Fahrzeuge bedient sich der Fahrzeuglenker gewöhnlich eines Außen- und Innenspiegels. Es existiert jedoch seitlich ein toter Sichtbereich, der durch die Spiegel nicht einsehbar ist, so daß der Fahrzeuglenker bei einem Fahrspurwechsel noch zusätzlich seitlich zurückblicken muß, um in diesen kritischen Bereich einsehen zu können. Unterbliebt das Zurückblicken, so besteht beim Fahrspurwechsel Unfallgefahr. Jedoch entsteht ebenfalls eine kritische Situation während der Zeit, in der sich der Fahrzeuglenker umdreht. Eine bekannte Lösung dieses Problems ist sin geteilter Außenspiegel mit unterschiedlichen Winkelsteffungen, wobei eine Winkelstellung dem toten, rückwärtigen Sichtbereich zugeordnet ist. Dabei muß der Fahrzeuglenker jedoch drei Sichtfelder (Innenspiegel sowie zwei Bereiche des Außenspiegels) verarbeiten, was leicht zu Irritierungen führt.The invention relates to a device according to the preamble of the main claim. The driver usually uses an exterior and interior mirror to detect such vehicles. However, there is a dead viewing area on the side, which cannot be seen through the mirrors, so that the vehicle driver must also look back sideways when changing lanes in order to be able to see into this critical area. If you do not look back, there is a risk of accident when changing lanes. However, a critical situation also arises during the time the driver turns around. A known solution to this problem is a divided exterior mirror with different angular effects, an angular position being associated with the dead, rear viewing area. However, the driver must process three fields of vision (inside mirror and two areas of the outside mirror), which easily leads to irritation.
Zur Erleichterung des Einparkens eines Kraftfahrzeuges sind aus der DE-OS 2 312 2U8 , der DE-OS 2 531 665, der AT-PS 248 894 sowie der DE-OS 32 07 950 berührungslose Abstandsmeßvorrichtungen bekannt, die insbesondere nach dem Ultraschall- oder Infrarot-Prinzip arbeiten. Diese eignen sich jedoch nicht zur Kontrolle überholender Fahrzeuge.To facilitate the parking of a motor vehicle non-contact distance measuring devices are known from DE-OS 2 312 2U8, DE-OS 2 531 665, AT-PS 248 894 and DE-OS 32 07 950, in particular according to ultrasound or infrared -Principle work. However, these are not suitable for checking overtaking vehicles.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, daß der Fahrer auf eindringliche Art bei einem geplanten Fahrspurwechsel auf ein Fahrzeug im rückwärtigen toten Sichtbereich aufmerksam gemacht wird, ohne daß er sich umdrehen muß und ohne daß seine Aufmerksamkeit durch zu viele Spiegel abgelenkt wird.The device according to the invention with the characterizing features of the main claim has the advantage that the driver is urgently made aware of a vehicle in the rear blind field of view when he is planning to change lanes without having to turn around and without his attention being distracted by too many mirrors becomes.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich. Besonders vorteilhaft ist die Ausgestaltung der Kontrolleinrichtung als Kontrolleuchte, insbesondere Leuchtdiode an einem Rückspiegel. Weiterhin ist es besonders günstig, die Erfassung eines anderen Fahrzeugs nur dann anzuzeigen, wenn gleichzeitig ein Fahrtrichtungsanzeiger betätigt ist, also wenn der Fahrer einen Fahrspurwechsel beabsichtigt.Advantageous further developments and improvements of the device specified in the main claim are possible through the measures listed in the subclaims. The configuration of the control device as a control lamp, in particular a light-emitting diode on a rearview mirror, is particularly advantageous. Furthermore, it is particularly expedient to display the detection of another vehicle only if a direction indicator is simultaneously present is actuated, i.e. when the driver intends to change lanes.
Zeichnungdrawing
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 eine schematische Darstellung der verschiedenen Beobachtungssysteme für von hinten kommende andere Fahrzeuge und Figur 2 eine schaltungsmäßige Ausgestaltung des Ausführungsbeispiels.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a schematic illustration of the various observation systems for other vehicles coming from behind, and FIG. 2 shows a circuit-like embodiment of the exemplary embodiment.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Ein Fahrzeug 10 bewegt sich auf der rechten Fahrspur 11 einer Straße 12, die noch zusätzlich eine linke Fahrspur 13 aufweist. Das Fahrzeug 10 besitzt einen Innenspiegel 14. sowie einen Außenspiegel 15. Die durch diese Spiegel 14 , 15 gegebenen rückwärtigen Sichtbereiche 16, 17 sind verschieden schraffiert dargestellt. Am hinteren Ende des Fahrzeugs ist seitlich eine berührungslose Abstandsmeßvorrichtung 18 angebracht, die seitlich einen leicht nach hinten gerichteten Meßstrahl 19 erzeugt. Der Kegel dieses Meßstrahls 19 kann ein überholendes Fahrzeug 20 auf der linken Fahrspur 13 auch außerhalb der Sichtbereiche 16, 17 erfassen und dem Fahrer anzeigen, wie dies in Figur 2 näher erläutert ist. Die Abstandsmeßvorrichtung 18 kann vorzugsweise an der hinteren Stoßstange angebracht sein.A vehicle 10 moves in the right lane 11 of a road 12 which also has a left lane 13. The vehicle 10 has an inside mirror 14 and an outside mirror 15. The rear viewing areas 16, 17 given by these mirrors 14, 15 are shown differently hatched. At the rear end of the vehicle, a non-contact distance measuring device 18 is attached to the side, which generates a measuring beam 19 directed slightly to the rear. The cone of this measuring beam 19 can also detect an overtaking vehicle 20 in the left lane 13 outside the viewing areas 16, 17 and display it to the driver, as is explained in more detail in FIG. 2. The distance measuring device 18 can preferably be attached to the rear bumper.
In der in Figur 2 dargestellten Schaltungsanordnung ist der Abstandsmeßvorrichtung 18 eine Auswerteschaltung 21 nachgeschaltet, deren Ausgangssignal über ein UND-Verknüpfungsglied 22 eine vorzugsweise als Leuchtdiode ausgebildete optische Kontrolleinrichtung 23 steuert. Diese Kontrolleinrichtung 23 ist am Rückspiegel 24 des Fahrzeugs angebracht. Durch einen Fahrtrichtungsschalter 25 ist ein linker und rechter Fahrtrichtungsanzeiger 26, 27 einschaltbar. Das Steuersignal für den linken Fahrtrichtungsanzeiger 26 ist zusätzlich einem weiteren Eingang des UND-Verknüpfungsglieds 22 zugeführt. Die Ansteuerung der Kontrolleinrichtung 23 kann natürlich unter Umständen eine zur Vereinfachung nicht näher dargestellte Treiberstufe erfordern.In the circuit arrangement shown in FIG. 2, the distance measuring device 18 is followed by an evaluation circuit 21, the output signal of which controls an optical control device 23, which is preferably designed as a light-emitting diode, via an AND gate 22. This control device 23 is on the rear-view mirror 24 attached to the vehicle. A left and right direction indicator 26, 27 can be switched on by a direction switch 25. The control signal for the left direction indicator 26 is additionally fed to a further input of the AND gate 22. The control of the control device 23 can of course, under certain circumstances, require a driver stage, which is not shown for the sake of simplicity.
Die Wirkungsweise der dargestellten Anordnung besteht darin, daß durch die Abstandsmeßvorrichtung 18 Gegenstände innerhalb des vorgesehenen Meßbereichs von einigen Metern registriert werden können. Diese Begrenzung der Reichweite ist deshalb erforderlich , um die Erfas sung von Gegenständen am linken Straßenrand auszuschließen. Solche berührungslose Abstandsmeßvorrichtungen sind im eingangs angegebenen Stand der Technik näher dargestellt und beruhen generell auf dem Prinzip der Absendung eines Meßstrahls (Welle) von der Abstandsmeßvorrichtung aus in die gewünschte Richtung und der Wiedererfassung des gegebenenfalls reflektierten Meßstrahls. Zur Messung können dazu prinzipiell Ultraschall-, Infrarot-, Radar- oder sonstige elektromagnetische Wellen verwendet werden. Die Abstandsmeßvorrichtung 18 besteht somit aus einem Sender und einem Empfänger. Die elektronische Auswerteschaltung 21 wandelt das reflektierte und wiederempfangene Signal gemäß dem eingangs angegebenen Stand der Technik in ein Steuersignal um, das ein Fahrzeug im rückwärtigen toten Sichtbereich signalisiert. Über das UND-Ver¬knüpfungsglied 22 wird dann die Kontrolleinrichtung 23 eingeschaltet, sofern am zweiten Eingang des UND-Verknüpfungsglieds 22. ebenfalls ein Steuersignal anliegt. Dies ist dann der Fall, wenn gleichzeitig der linke Fahrtrichtungsanzeiger 26 eingeschaltet ist. In einer einfacheren Version kann unter Weglassung des Einflusses der Fahrtrichtungsanzeiger 26, 27 der Ausgang der Auswerteschaltung 21 auch direkt mit der Kontrolleinrichtung 23 verbunden sein. Diese Kontrolleinrichtung kann alternativ oder zusätzlich auch als akustische Kontrolleinrichtung, insbesondere als Summer oder Lautsprecher ausgebildet sein.The mode of operation of the arrangement shown is that objects can be registered by the distance measuring device 18 within the intended measuring range of a few meters. This limitation of the range is therefore necessary to prevent objects from being detected on the left side of the road. Such non-contact distance measuring devices are shown in more detail in the prior art specified at the outset and are generally based on the principle of sending a measuring beam (wave) from the distance measuring device in the desired direction and the detection of the possibly reflected measuring beam. In principle, ultrasound, infrared, radar or other electromagnetic waves can be used for the measurement. The distance measuring device 18 thus consists of a transmitter and a receiver. The electronic evaluation circuit 21 converts the reflected and received signal in accordance with the prior art specified at the outset into a control signal which signals a vehicle in the rear blind area. The control device 23 is then switched on via the AND link 22, provided that a control signal is also present at the second input of the AND link 22. This is the case when the left direction indicator 26 is switched on at the same time. In a simpler version, the output of the evaluation circuit 21 can also be connected directly to the control device 23, without the influence of the direction indicators 26, 27. As an alternative or in addition, this control device can also be designed as an acoustic control device, in particular as a buzzer or loudspeaker.
Die beschriebene Anordnung kann vorzugsweise mit weiteren berührungslosen Abstandsmeßvorrichtungen am Fahrzeug kombiniert werden, insbesondere Abstandsmeßvorrichtungen am hinteren Ende des Fahrzeugs zur Erleichterung des Einparkens. The arrangement described can preferably be combined with other non-contact distance measuring devices on the vehicle, in particular distance measuring devices at the rear end of the vehicle to facilitate parking.
