Abstract
Description
Bisher werden bei Verkehrsmitteln, insbesondere Kraftfahrzeugen, Abblendlicht und Fernlicht vom Benutzer über entsprechende Schalter am Armaturenbrett je nach Umgebungssituation an- oder ausgestellt.So far, low beam and high beam have been used in means of transport, in particular motor vehicles by the user using appropriate switches on the dashboard depending on the surrounding situation turned on or off.
Es ist ein jedem bekanntes Problem, daß bei Dämmerung oder zum Beispiel bei starken Niederschlägen oft das Abblendlicht nicht rechtzeitig eingeschaltet wird. Dies führt dazu, daß andere Verkehrsteilnehmer das Kraftfahrzeug nicht rechtzeitig sehen und somit Unfallsituationen herbeiprovoziert werden. Auf der anderen Seite wird zum Beispiel oft nach Tunnels vergessen, das Abblendlicht wieder auszuschalten. Weiterhin wird häufig vergessen, das Fernlicht beispielsweise in Ortschaften auszuschalten. Dies führt ebenfalls zu teilweise erheblichen Gefahrensituationen, da andere Verkehrsteilnehmer geblendet werden. Ziel der Erfindung ist es, den prozentualen Anteil der Fälle, in denen beim Benutzer des Verkehrsmittels das Abblend- bzw. Fernlicht manuell ein- oder auszuschalten ist, auf ein absolutes Minimum zu reduzieren.It is a problem known to everyone that at dusk or during heavy rainfall, for example often the low beam is not switched on in time. This leads to others Road users do not see the motor vehicle in time and thus accident situations be provoked. On the other hand, after tunnels, for example, people often forget turn off the low beam again. It is also often forgotten, for example the high beam to turn off in towns. This also leads to sometimes considerable dangerous situations, because other road users are blinded. The aim of the invention is the Percentage of cases in which the dimming or High beam must be switched on or off manually to an absolute minimum.
Dieses Gesamtproblem wird durch die Patentansprüche 1 bis 8 gelöst; als Ausführungsbeispiel dient im folgenden die Anwendung an einem Personenkraftwagen. Wie aus den Fig.1 und 2 zu erkennen ist, wird durch diese der Teil der Erfindung, der durch Patentanspruch 1 charakterisiert ist, verdeutlicht. Die Lösung des Problems, daß der Verkehrsteilnehmer das Abblendlicht nicht rechtzeitig ein- oder ausschaltet, geschieht dadurch, daß man mindestens einen Lichtsensor, bestehend aus einem Photowiderstand, die augenblickliche Umgebungshelligkeit messen läßt, und erst wenn die Umgebung an allen Stellen am Verkehrsmittel, wo sich Lichtsensoren befinden, einen Helligkeitsgrad x unter- oder überschreitet, schaltet sich das Abblendlicht automatisch über ein Relais ein oder aus. Hierzu siehe auch Fig. 2.This overall problem is solved by claims 1 to 8; as an example, the application in the following is used on a passenger car. As can be seen from FIGS. 1 and 2, this clarifies the part of the invention which is characterized by claim 1. The solution to the problem that the road user does not switch the dipped headlights on or off in good time is achieved by having at least one light sensor, consisting of a photoresistor, measure the instantaneous ambient brightness, and only when the surroundings at all points on the means of transport, where If there are light sensors, a brightness level x below or exceeds, the low beam switches on or off automatically via a relay. See also Fig. 2.
Das Problem kurzzeitiger Umgebungshelligkeitsschwankungen zum Beispiel durch Hochhaus- oder Brückenschatten, bei denen das Abblendlicht nach Patentanspruch 1 reagieren würde, wird durch zwei Komponenten in Patentanspruch 2 gelöst. Es wird erstens gelöst durch die Verteilung mehrerer, möglichst weit voneinander liegender Lichtsensoren längs des Verkehrsmittels und zudem durch Tantal-Elektrolytkondensatoren, die parallel zu den Photowiderständen geschaltet sind, weil somit der Effekt kleiner Schatten kompensiert wird, und zweitens wird es auch gelöst durch den in Fig. 2 ersichtlichen Kondensator C1, der bewirkt, daß bei kurzzeitigen Helligkeitserhöhungen das Abblendlicht nicht direkt ausgeschaltet wird.The problem of brief ambient brightness fluctuations, for example due to high-rise or bridge shadows, in which the low beam would react according to claim 1, is solved by two components in claim 2. It is firstly solved by distributing several light sensors as far apart as possible along the means of transport and also by tantalum electrolytic capacitors, which are connected in parallel to the photoresistors, because this compensates for the effect of small shadows, and secondly, it is also solved by the in Fig. 2 visible capacitor C1, which causes the low beam is not turned off directly at brief increases in brightness.
Das Problem, daß bei Niederschlägen oft vergessen wird, das Licht einzuschalten, wird, wie in Patentanspruch 3 beschrieben, gelöst. Auf diese Weise wird das Abblendlicht automatisch angestellt, sobald der Scheibenwischer auf irgendeine Form von Dauerbetrieb geschaltet ist. Praktisch wird dies durch einen Scheibenwischerschalter realisiert, der zwei voneinander unabhängige Stromkreise auf mechanische Weise gleichzeitig schließen oder unterbrechen kann.The problem that it is often forgotten to switch on the light during rainfall, as in Described claim 3, solved. In this way, the low beam is switched on automatically, as soon as the wiper is switched to some form of continuous operation. Practically this is realized by a windshield wiper switch, which is independent of two Can mechanically close or interrupt circuits simultaneously.
Das Problem, das Fernlicht nicht rechtzeitig ein- oder auszuschalten, wird durch Patentanspruch 4 gelöst: ist das Abblendlicht eingeschaltet, wird eine integrierte, halbautomatische Fernlichtsteuerung aktiv. Diese Steuerung ist dadurch charakterisiert, daß das Ein- und Ausschalten des Fernlichts mittels mehrerer, parallel geschalteter Lichtsensoren, analog zu Patentanspruch 1, allerdings mit deutlich lichtempfindlicheren Photowiderständen als den in Patentanspruch 1 erwähnten, geregelt wird. Die zugehörige Schaltung geht aus Fig. 3 hervor. Die Lichtsensoren sollen sich bei einem Kraftfahrzeug vorne und in der Mitte auf dem Fahrzeugdach, aber unter keinen Umständen am Heck befinden, um den Einfluß von hinten eintreffenden Lichts anderer Fahrzeuge zu minimieren.The problem of not switching the high beam on or off in good time is solved by claim 4: If the low beam is switched on, an integrated, semi-automatic high beam control is activated. This control is characterized in that the switching on and off of the high beam is regulated by means of a plurality of light sensors connected in parallel, analogously to patent claim 1, but with significantly more light-sensitive photoresistors than those mentioned in patent claim 1. The associated circuit is shown in Fig. 3. In a motor vehicle, the light sensors should be located in the front and in the middle on the vehicle roof, but under no circumstances at the rear, in order to minimize the influence of light from other vehicles arriving from behind.
Um den Einfluß störender Lichtquellen zu vermeiden, sind alle Lichtsensoren von einem semitransparenten Schutzkörper, wie in Patentanspruch 6 beschrieben, umgeben. Hierzu siehe auch Fig. 4.In order to avoid the influence of disturbing light sources, all light sensors are surrounded by a semi-transparent protective body, as described in claim 6. See also FIG. 4.
Wie in Patentanspruch 5 erläutert, soll seriell zu dem Lichtsensor, der sich vorne am Verkehrsmittel befindet, ein Kompensationswiderstand nach Fig. 2b angebracht sein, der das Problem des Einflusses des vor dem Verkehrsmittel zurückgestreuten, eigenen Lichts, welches sonst eine Erhöhung des Stromes durch diesen Lichtsensor zur Folge hätte, löst.As explained in claim 5, a compensation resistor according to FIG. 2b should be attached in series with the light sensor located at the front of the means of transport, which solves the problem of the influence of the own light scattered back in front of the means of transport, which would otherwise increase the current through it Light sensor would result.
Wenn sich das Verkehrsmittel in einer Umgebung sehr geringer Helligkeit befindet, so daß das Fernlicht über die entsprechende Steuerung aktiviert wird, kann auf diese Weise jedes Objekt, das kein nicht vom fahreigenen Verkehrsmittel stammendes Licht aussendet oder reflektiert, sehr früh vom Benutzer registriert und identifiziert werden. Dies gilt insbesondere für auf die Straße laufendes Wild bei Kraftfahrzeugen. Da nur das menschliche Gehirn Wild als solches kostengünstig zu identifizieren vermag, muß die Fernlichtsteuerung halbautomatisch sein, so daß nach rechtzeitigem Erkennen des Wildes manuell von Fernlicht auf Abblendlicht umgeschaltet werden kann. Der Konsistenz halber wird auch bei der Abblendlichtschaltung eine manuelle Kontrollmöglichkeit integriert, so daß dem Fahrer generell Handlungspriorität unterliegt. Dies wird so realisiert, daß am Armaturenbrett ein zusätzlicher Schalter, im folgenden Automatikschalter genannt, angebracht wird. Dieser Schalter kann auf mechanische Weise gleichzeitig den Stromkreis für die automatische Abblendlichtsteuerung unterbrechen und den für die manuelle Steuerung schließen. Der Automatikschalter befindet sich direkt neben den Bedienungselementen für die manuelle Steuerung und wird auf mechanische Weise automatisch auf manuellen Betrieb geschaltet, wenn Abblend- oder Fernlicht manuell angestellt wird.If the means of transport is in an area of very low brightness, so that High beam can be activated via the corresponding control, this way every object, that does not emit or reflect light that does not come from the vehicle’s own means of transport, be registered and identified by the user very early. This applies in particular to the Road running game in motor vehicles. Because only the human brain is wild as such Can identify the low-cost, the high-beam control must be semi-automatic, so that after timely detection of the game manually switched from high beam to low beam can be. For the sake of consistency, the low beam switch is also manual Control option integrated so that the driver is generally subject to priority action. This is realized so that an additional switch on the dashboard, in the following automatic switch called, is attached. This switch can be operated mechanically at the same time interrupt the circuit for automatic low beam control and the circuit for manual Close control. The automatic switch is located right next to the controls for manual control and is automatically opened in a mechanical way Manual mode switched when dipped or main beam is switched on manually.
