Opaque screen elements have a degree of darkening of 100% (degree of transmission 0%). In addition, the size of the blend element is fixed and cannot be adapted to the apparent size of the dazzling object. As a result, either the glare object is not completely darkened, ie a residual glare remains, or the glare element covers the glare object by far and thereby impairs the driver's field of vision, which is also undesirable and is perceived as disturbing. In general, mechanical devices react with certain time delays, so that a quick reaction to sudden light reflections is also not possible.

BLENDSCHUTZEINRICHTUNG FÜR EIN KRAFTFAHRZEUG GLARE PROTECTION DEVICE FOR A MOTOR VEHICLE
UND VERFAHREN ZUR STEUERUNG EINER BLENDSCHUTZEINRICHTUNG FÜR EIN KRAFTFAHRZEUGAND METHOD FOR CONTROLLING AN IRIS PROTECTION DEVICE FOR A MOTOR VEHICLE
Die Erfindung betrifft eine Blendschutzeinrichtung für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Steuerung einer Blendschutzeinrichtung für ein Kraftfahrzeug.The invention relates to a glare protection device for a motor vehicle according to the preamble of claim 1 and a method for controlling a glare protection device for a motor vehicle.
Es ist allgemein bekannt, daß bei Nachtfahrten Blendwirkungen von entgegenkommenden Kraftfahrzeugen eine erhebliche Verkehrsgefährdung darstellen. Durch diese Blendwirkungen ist der Fahrer eines Kraftfahrzeuges nicht mehr in der Lage, die Verkehrssituation richtig zu erfassen. Insbesondere schlecht beleuchtete bzw. unbeleuchtete Hindernisse werden entweder gar nicht oder viel zu spät erkannt.It is generally known that glare effects from oncoming motor vehicles pose a considerable risk to traffic when driving at night. As a result of these glare effects, the driver of a motor vehicle is no longer able to correctly record the traffic situation. In particular, poorly lit or unlit obstacles are either not recognized at all or are recognized too late.
Aber auch bei Tageslicht kann es durch direkte Sonneneinstrahlung oder durch Sonnεnlichtreflexe an Glasflächen zu gefährlichenBut even in daylight it can be dangerous due to direct sunlight or sunlight reflections on glass surfaces
Blendungwirkungen kommen, die mit herkömmlichen Sonnenblenden nicht zu vermeiden sind.Glare effects that cannot be avoided with conventional sun visors.
Aus der DE 34 43 488 ist eine ansteuerbare Filterscheibe inbesondere für Kraftfahrzeuge bekannt, die mehrere fest vorgegebene Flüssigkeitskristallbereiche aufweist, mit deren Hilfe größere Ausschnitte der Filterscheibe abgedunkelt werden können. Dadurch wird zwar die Blendwirkung verringert, gleichzeitig jedoch das Sichtfeld des Fahrers erheblich eingeschränkt.From DE 34 43 488 a drivable filter disk, especially for motor vehicles, is known, which has a plurality of predetermined liquid crystal regions, with the help of which larger sections of the filter disk can be darkened. This reduces glare, but at the same time considerably limits the driver's field of vision.
Aus der DE 39 36 120 ist ein Blendelement bekannt, das im Bereich der Windschutzscheibe des Kraftfahrzeuges angeordnet ist und einen gewissen Bereich des Sichtfeldes des Fahrers abdeckt. Das Blendelement wird mechanisch bewegt.From DE 39 36 120 a screen element is known which is arranged in the area of the windshield of the motor vehicle and covers a certain area of the driver's field of vision. The screen element is moved mechanically.
Solche mechanische Vorrichtungen haben verschiedene Nachteile. Zum einem ist deren mechanische Ans euerung sehr aufwendig. Zum anderem läßt sich der Grad der Abdunkelung bzw. der Transmissionsgrad eines derartigen Blendelementes nicht variieren. Undurchsichtige Blendelemente weisen einen Abdunkelungsgrad von 100% (Traπsmissionsgrad 0%) auf. Außerdem ist die Größe des Blendelementes fest vorgegeben und nicht an die scheinbare Größe des blendenden Objekts anpassbar. Dadurch wird entweder das Blendobjekt nicht vollständig abgedunkelt, d.h. es verbleibt eine Restblendwirkung oder aber das Blendelement überdeckt das Blendobjekt bei weitem und beeinträchtigt dadurch das Sichtfeld des Fahrers, was ebenfalls unerwünscht ist und als störend empfunden wird. Allgemein reagieren mechanische Einrichtungen mit gewissen zeitlichen Verzögerungen, so daß eine schnelle Reaktion auf plötzlich auftretende Lichtreflexe ebenfalls nicht möglich ist.Such mechanical devices have several disadvantages. On the one hand, their mechanical control is very complex. On the other hand the degree of darkening or the degree of transmission of such a screen element cannot be varied. Opaque screen elements have a degree of darkening of 100% (degree of transmission 0%). In addition, the size of the blend element is fixed and cannot be adapted to the apparent size of the dazzling object. As a result, either the glare object is not completely darkened, ie a residual glare remains, or the glare element covers the glare object by far and thereby impairs the driver's field of vision, which is also undesirable and is perceived as disturbing. In general, mechanical devices react with certain time delays, so that a quick reaction to sudden light reflections is also not possible.
Aufgabe der Erfindung ist es, eine Blendschutzeinrichtung für ein Kraftfahrzeug und ein Verfahren zur Steuerung einer Blendschutzeinrichtung für ein Kraftfahrzeug anzugeben, die die oben angegebenen Nachteile vermeiden, die insbesondere eine verzögeruπgsfreie Ausblendung des Blendobjektes erlauben, die eine Anpassung an das blendenden Objektes ermöglichen und die einfach und kostengünstig herstellbar bzw. durchführbar sind.The object of the invention is to provide an anti-glare device for a motor vehicle and a method for controlling an anti-glare device for a motor vehicle, which avoid the disadvantages specified above, which in particular allow delay-free masking of the glare object, which enable adaptation to the glare object and which are simple and can be produced and carried out inexpensively.
Gelöst wird diese Aufgabe durch die im Anspruch 1 angegebenen Mittel bzw. im Anspruch 2 angegebenen Verfahrensschritte.This object is achieved by the means specified in claim 1 or method steps specified in claim 2.
Die wesentliche Idee der Erfindung besteht darin, eine abduπkelbare Filterscheibe matrixartig auszubilden, wobei einzelne Matrixelemente der Filterscheibe abduπkelbar sind. Angesteuert wird die Filterscheibe über eine Steuereinheit, die mit Sensoren zum Erfassen eines Blendobjektes und mit einer Kamera zum Erfassen der momentanen Augenpositioπ eines Kraftfahrzeuginsassen verbunden ist. In der Steuereinheit wird der Schnittpunkt (Durchtrittspuπkt) des Lichtweges „Blendobjekt" „Augenposition Fahrzeugiπsasse" mit der Filterscheibe bestimmt und durch entsprechende Ansteuerung der Filterscheibe dieser Bereich der Filterscheibe abgedunkelt.The essential idea of the invention is to design a filter plate that can be uncoupled, in which case individual matrix elements of the filter disc can be uncoupled. The filter disk is controlled via a control unit, which is connected to sensors for detecting a glare object and to a camera for detecting the current eye position of a motor vehicle occupant. The point of intersection (passage point) of the light path “glare object” “eye position vehicle occupant” with the filter disk is determined in the control unit, and this area of the filter disk is darkened by appropriate activation of the filter disk.

In Figur 1 ist eine erfmdungsgemaße Blendschutzeinrichtung 1 anhand einer Aufsicht auf den Frontscheibenbereich eines Kraftfahrzeuges von oben schematisch dargestellt Die Blendschutzeinπchtuπg 1 besteht im wesentlichen aus einer abdunkelbaren Filterscheibe 10, die mit einer Steuereinheit 20 über eine Steuerleitung 25b verbunden ist Der genauere Aufbau der Filterscheibe 10 ist in Fig 2 dargestelltFIG. 1 schematically shows an anti-glare device 1 according to the invention based on a view of the front window area of a motor vehicle. The anti-glare device 1 essentially consists of a darkened filter disk 10, which is connected to a control unit 20 via a control line 25b. The filter disk 10 is more precisely constructed shown in Fig. 2
Bei der Filterscheibe 10 handelt es sich um die Frontscheibe eines nicht naher dargestellten Kraftfahrzeuges 50 Sie begrenzt den Innenraum 52 des Kraftfahrzeuges 50 Im Iπnenraum 52 sind auf den Vordersitzen je zwei Kraftfahrzeuginsasseπ, ein Fahrer und ein Beifahrer, durch deren entsprechende Augenpositionen 40 bzw 42 schematisch angedeutet Die Augenposition 40 bzw 42 wird mit einer Kamera 24 erfaßt, die ebenfalls im Iπnenraum 52 angeordnet ist Die Kamera 24 ist über eine Verbindungsleitung 25c an die Steuereinheit 20 angeschlossen Vor der Filterscheibe 10 ist ein Blendobjekt 30 angedeutet, bei dem es sich z B um ein entgegenkommendes Fahrzeug, um direktes Sonnenlicht oder um einen Sonnenlichtreflex handeln kann Zum Erfassen des Blendobjektes dienen je zwei Sensoren 22a, 22b, die im dargestellten Fall jeweils im Raπdbereich der Filterscheibe 10 angeordnet sind und über Verbindungsleitungen 25a bzw 25d mit der Steuereinheit 20 verbunden sind Die beiden Sensoren 22a, 22b können aber auch an einer beliebigen anderen Stelle im vorderen Bereich des Kraftfahrzeugs 50 angeordnet sein Wichtig hierbei ist nur, daß die beiden Sensoren 22a, 22b jeweils eine freie Sicht in Richtung Blendobjekt 30 ermöglichen Mit Ziffer 32 ist der Lichtweg vom Blendobjekt 30 zur Augenposition 40 bezeichnet Der Lichtweg 32 schneidet die Filterscheibe 10 im Druchtπttspunkt 34The filter pane 10 is the front pane of a motor vehicle 50 (not shown in more detail). It delimits the interior 52 of the motor vehicle 50. In the interior 52, two motor vehicle occupants, a driver and a passenger, are indicated schematically on the front seats by their corresponding eye positions 40 and 42, respectively The eye position 40 or 42 is recorded by a camera 24, which is also arranged in the interior 52. The camera 24 is connected to the control unit 20 via a connecting line 25c. A dazzling object 30 is indicated in front of the filter disk 10, which is, for example, a Oncoming vehicle, direct sunlight or a sunlight reflex can be used to detect the dazzling object, two sensors 22a, 22b each, which in the case shown are each arranged in the rim area of the filter disk 10 and are connected to the control unit 20 via connecting lines 25a and 25d, respectively Sensors 22a, 22b can a Be arranged at any other point in the front area of the motor vehicle 50. The important thing here is that the two sensors 22a, 22b each provide a clear view in the direction of the glare object 30. Numeral 32 denotes the light path from the glare object 30 to the eye position 40 The light path 32 intersects the filter disk 10 at the Druchtπttspunkt 34th
In Figur 2 ist der Aufoau der Filterscheibe 10 naher dargestellt Die Filterscheibe 10 ist matrixartig aufgebaut d h sie besteht aus einer Vielzahl von Matrixelementen 38, die über eine über entsprechende Ansteueruπg der Filterscheibe 10 durch die Steuereinheit 20 einzeln abdunkelbar sind Bei den Matrixelementen 38 kann es sich z B Flussigkπstallelemente (LCD) handeln. Denkbar sind auch separat aπsteuerbare elektrochrome Elemente oder laseraktive Elemente, die über Laserbestrahlung ihren Transmissioπsgrad ändern.The structure of the filter disk 10 is shown in more detail in FIG. 2. The filter disk 10 is constructed in a matrix-like manner, ie it consists of a multiplicity of matrix elements 38 which can be individually darkened by the control unit 20 via a corresponding control of the filter disk 10 eg liquid stall elements (LCD) act. Separately controllable electrochromic elements or laser-active elements that change their degree of transmission via laser radiation are also conceivable.
Durch eine entsprechende Ansteueruπg über die Steuereinheit 20 läßt sich nicht nur der Abdunkeluπgsgrad jedes einzelnen Matrixelementes 38 sondern natürlich auch die Größe des abgedunkelten Bereiches 36 verändern und so der scheinbaren Größe des Blendobjektes 30 anpassen.By means of a corresponding control via the control unit 20, not only the degree of darkening of each individual matrix element 38 but of course also the size of the darkened area 36 can be changed and thus adapted to the apparent size of the glare object 30.
Nachfolgend ist die Funktionsweise der Bleπdschutzeinrichtung und das erfiπdungsgemäße Verfahren näher erläutert.The mode of operation of the lead protection device and the method according to the invention are explained in more detail below.
Nähert sich dem Fahrzeug 50 ein entgegenkommendes Fahrzeug mitAn oncoming vehicle approaches the vehicle 50
Scheinwerfereiπstellungen, die eine Blendung des Fahrers 40 darstellen bzw. darstellen könnten, so wird im Verfahrensschritt a) mit Hilfe der beidenHeadlight settings, which represent or could represent glare to the driver 40, are carried out in method step a) with the help of the two
Sensoren 22a, 22b das Blendobjekt 30 erfaßt und in der Steuereinheit 20 seine Richtung bzw. seine Position relativ zum Fahrzeug bestimmt. ImSensors 22a, 22b detect the glare object 30 and determine its direction or position relative to the vehicle in the control unit 20. in the
Verfahrensschritt b) wird mit Hilfe der Kamera 24 die momentaneMethod step b) uses the camera 24 to determine the current one
Augenposition 40 des Fahrers erfaßt. Anschließend wird imEye position 40 of the driver detected. Then in
Verfahreπsschritt c) der Lichtweg 50 vom Blendobjekt 30 zur AugeπpositionMethod step c) the light path 50 from the glare object 30 to the eye position
40 des Fahrers in der Steuereinheit 20 berechnet und der Durchtrittspunkt40 of the driver calculated in the control unit 20 and the point of passage
34 des Lichtweges 50 durch die Filterscheibe 10 festgelegt.34 of the light path 50 through the filter disk 10.
Im weiteren Verfahrensschritt d) steuert die Steuereinheit 20 dieIn the further method step d), the control unit 20 controls the
Filterscheibe 10 derart an, daß der Bereich 36 des Durchtrittspunkts 34 abgedunkelt wird.Filter disk 10 so that the area 36 of the passage point 34 is darkened.
Die Ansteuerung der Filterscheibe 10 erfolgt so, daß der abgedunkelteThe control of the filter disc 10 is carried out so that the darkened
Bereich 36 entsprechend der Bewegung des Blendobjektes 30 nachgeführt wird und somit z.B. ein entgegenkommendes Fahrzeug bis zur Vorüberfahrt abgedunkelt bleibt.Area 36 is tracked according to the movement of the dazzling object 30 and thus e.g. an oncoming vehicle remains darkened until it passes.
Durch diese Maßnahme erfolgt keine bzw. nur eine geringe Blendwirkung des Fahrers, was erheblich zur Verkehrssicherheit beiträgt. Der Fahrer kann nunmehr auch unbeleuchtete bzw. schlecht beleuchtete Hindernisse rechtzeitig erkennen und entsprechend reagieren.This measure results in little or no glare for the driver, which contributes significantly to traffic safety. The driver can now recognize unlit or poorly lit obstacles in good time and react accordingly.
In einer vorteilhafte Weiterentwicklung des erfindungsgemäßen Verfahrens wird im Verfahrenschritt a1 ) mit Hilfe der Sensoren 22a, 22b auch die scheinbare Größe des Blendobjektes 30 auf der Filterscheibe 10 bestimmt und die Größe des Bereichs 36 entsprechend festgelegt.In an advantageous further development of the method according to the invention, the apparent size of the glare object 30 on the filter disk 10 is also determined in method step a1) with the aid of the sensors 22a, 22b and the size of the area 36 is determined accordingly.
Die Größe des abgedunkelten Bereichs 36 wird damit gerade so groß, daß der Schattenwurf die Augenpositioπ 40 des Fahrers überdeckt. Aufgrund der angepaßten geringen Größe des abgedunkelten Bereichs 36 ist das Gesichtsfeld des Fahrers nur punktuell eingeschränkt und zwar genau in dem Bereich, der zu einer Blendwirkuπg fuhren würdeThe size of the darkened area 36 thus becomes just so large that the shadow cast covers the driver's eye position 40. Because of the adapted small size of the darkened area 36, the driver's field of vision is only limited in certain areas, specifically in the area that would lead to glare
In einer Weiterentwicklung des Verfahrens wird im Verfahrenschritt a2) mit Hilfe der Sensoren 22a, 22b auch die Lichtintensitat des Blendobjektes 30 bestimmt. Die Steuereinheit 20 steuert daraufhin die Filterscheibe 10 derart an, daß der abgedunkelte Bereich 36 in seinem Transmissionsverhalten der Lichtintensitat des Blendobjektes 30 angepaßt ist Blendobjekte 30 geringerer Intensität werden deshalb für den Fahrer weniger stark abgedunkelt. Dadurch wird aber auch sein Sichtfeld weniger beeinflußt, was wiederum die Verkehrssicherheit erhöht.In a further development of the method, the light intensity of the glare object 30 is also determined in method step a2) with the aid of the sensors 22a, 22b. The control unit 20 then controls the filter disc 10 in such a way that the transmission behavior of the darkened area 36 is adapted to the light intensity of the glare object 30. Glare objects 30 of lower intensity are therefore darkened to a lesser extent for the driver. However, this also affects his field of vision less, which in turn increases traffic safety.
Selbstverständlich können mehrere Blendobjekte z.B mehrere entgegenkommende Fahrzeuge gleichzeitig ausgeblendet werdenOf course, several blind objects, e.g. several oncoming vehicles, can be hidden at the same time
Da die Blendwirkung auch für den Beifahrer störend sein kann, ist vorgesehen zusätzlich die Augeπposition des Beifahrers zu erfassen und einen entsprechenden Bereich für ihn abzudunkelnSince the glare effect can also be disruptive for the front passenger, provision is also made to detect the front passenger's eye position and darken a corresponding area for him
Da die Wirkung der Blendschutzeinrichtung ohne Verzögerung erfolgt, können auch Lichtblitze, die aufgrund von Spiegelungen an Glasflächen auftreten, rasch geschwächt werden.Since the anti-glare device works without delay, flashes of light that occur due to reflections on glass surfaces can be weakened quickly.
Mit Hilfe der erfiπdungsgemäßen Blendschutzeinrichtung ist in einfacher Weise ein abgedunkelter Bereich 36 verzögerungsfrei auf einer Filterscheibe 10 erzeugbar. Der Bereich 36 folgt der Bewegung des Blendobjektes 30 und paßt sich dem Blendobjekt 30 in seiner Größe und in seinem Abdunkelungsverhalten an Dadurch werden Bleπdwirkungen für den Fahrer erheblich vermindert und die Verkehrssicherheit so erhöht. With the help of the anti-glare device according to the invention, a darkened area 36 can be easily generated on a filter disk 10 without delay. The area 36 follows the movement of the glare object 30 and adapts to the glare object 30 in terms of its size and its darkening behavior. As a result, the effects on the driver are considerably reduced and the traffic safety is thus increased.
