Abstract

The dipped headlights of motor vehicles are still switched on today manually which involves a certain hazard for traffic and inconvenience for the driver of the motor vehicle. The invention presents an automatic system which assumes the function of switching the travel lights on and off as a function of the external light, in particular sunlight. For this purpose, the external light is tested by means of a photodetector for the presence of a specific wavelength which hardly occurs in artificial light. If the intensity of this light drops below a specific value, a switch-on delay is actuated which itself switches on the dipped headlights after approximately 5 seconds by means of a relay. If the intensity rises again above a value, the light is switched off with a delay of approximately 28 seconds. The delay is necessary to avoid the electronic system switching erratically on and off. The invention is intended as a new item of basic equipment for series production in the car industry.

Description

Die Erfindung betrifft eine Automatik, die in der Lage ist, das Abblendlicht eines KFZs selbsttätig ein- bzw. auszuschalten.The invention relates to an automatic system in the Is able to automatically switch the low beam of a car on or off.

Die Automatik soll einerseits den Fahrkomfort er­ heblich steigern, zum anderen einen wichtigen Bei­ trag zur Verkehrssicherheit liefern.On the one hand, the automatic should improve driving comfort significantly increase, on the other hand an important contribution deliver traffic safety.

Der bisherige Stand der Technik ist die manuelle Bedienung des KFZ-Lichts durch Schalter oder Hebel.The current state of the art is manual Operation of the car light by switch or lever.

Oftmals jedoch wird, gerade in Grenzsituationen (Dämmerung, häufige Tunnelein- und -ausfahrten), das Licht einfach vergessen. Die Gefahr für den flie­ ßenden Verkehr ist unverkennbar.Often, however, especially in borderline situations (Dusk, frequent tunnel entries and exits), just forget the light. The danger to the flie eating traffic is unmistakable.

Eine Automatik kann auch dadurch mehr Sicherheit bringen, daß noch weniger Aufmerksamkeit als bisher für die Bedienung des KFZ aufgewendet werden muß. Der Fahrzeugführer kann sich mehr auf das Führen des Fahrzeugs und auf den Verkehr konzentrieren.An automatic system can also be more secure bring that even less attention than before must be used to operate the vehicle. The Drivers can focus more on that Drive the vehicle and focus on traffic.

Der Erfindung liegt nun der Gedanke zugrunde, die Aufgabe des Ein-/Ausschaltens einer Automatik zu übertragen.The invention is based on the idea that Task of switching an automatic on / off transfer.

Die Lösung des geschilderten Problems ist eine Automatik, die das Abblendlicht je nach den äußeren Gegebenheiten ein- bzw. ausschaltet. Die Elektronik muß jedoch notwendiger­ weise unterscheiden können, ob es sich um Sonnen- (Tages-) licht handelt, oder ob das die Straße ausleuchtende Licht künstlicher Herkunft (Straßenbeleuchtung) ist. Auch darf es nicht durch kurzzeitige Beleuchtungsunterschiede zu einem hektischen ein- und ausschalten des Lichtes kommen.The solution to the problem described is an automatic one, the low beam depending on the external conditions switches on or off. However, the electronics must be more necessary can wisely distinguish whether it is solar (day) light, or whether the light illuminating the street of artificial origin (street lighting). Also allowed it is not due to brief lighting differences to one hectic light coming on and off.

Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. An embodiment is shown in the drawings and is described in more detail below.  

Bild 1 zeigt das Blockschaltbild der Erfindung. Figure 1 shows the block diagram of the invention.

Auf die Fotodiode fällt durch die Windschutzscheibe des Fahrzeugs von außen Licht ein. Vor die Fotodiode ist ein Filter plaziert, der nur Licht der Wellenlänge 470 nm (±10 nm) durchläßt. Die Wellenlänge 470 nm ist in allen üblichen, künstlichen Lichtquellen (Glüh­ lampen, Quecksilberhochdrucklampen, Natriumdampflampen) nur zu höchstens 40% relativer Stromdichte vorhanden. Im Tageslicht hingegen liegt der Anteil bei über 95%. Der nachgeschaltete Schwellwertschalter (Trigger) sorgt für die Empfindlichkeitseinstellung der Elektronik. Bei einem gewissen Strom, den die Fotodiode durch die Be­ strahlung freigibt, schaltet er durch, und gibt so der ihm folgenden Verzögerungsschaltung ein eindeutiges 1-Signal. Die Einschaltverzögerung verzögert bis zum Ansteuern des Relais um ca. 10 sec. (Bestimmbar durch die RC-Glieder in Bild 2.) Das Relais schließlich schaltet das Fahrzeuglicht in der durch die STVO gere­ gelten Art und Weise (Standlichter und Abblendlichter vorn, Rückleuchten hinten) ein.Light falls on the photodiode from the outside through the windshield of the vehicle. A filter is placed in front of the photodiode, which only allows light with a wavelength of 470 nm (± 10 nm) to pass through. The wavelength 470 nm is only available in all conventional artificial light sources (incandescent lamps, high-pressure mercury lamps, sodium vapor lamps) at a maximum of 40% relative current density. In contrast, in daylight the proportion is over 95%. The downstream threshold switch (trigger) ensures the sensitivity setting of the electronics. With a certain current, which the photodiode releases through the radiation, it switches on, giving the delay circuit following it a clear 1 signal. The switch-on delay is delayed by approx. 10 seconds until the relay is activated (can be determined by the RC elements in Figure 2.) The relay finally switches the vehicle light in the way that is stipulated by the road traffic regulations (parking lights and dipped lights at the front, rear lights at the rear ) a.

Wird die Fotodiode nun wieder durch Tageslicht beschie­ nen, (Ausfahrt aus dem Tunnel), so wird mit einer Ver­ zögerung von ca. 30 sec. der Relaishaltestrom unterbro­ chen, das Licht damit ausgeschaltet.If the photodiode is now bombarded with daylight again nen, (exit from the tunnel), so with a ver delay of approx. 30 sec chen, the light is switched off.

Die Option der manuellen Betätigung des Lichts soll je­ doch aus Sicherheitsgründen (Ausfall der Elektronik) er­ halten bleiben.The option of manual operation of the light should be different but for security reasons (failure of the electronics) hold on.

Bild 2 zeigt eine mögliche Schaltungsausführung der Regel- und Steuerungselektronik. Der Aufbau der Schaltung und deren Bauteile seien erläutert: Figure 2 shows a possible circuit design for the regulating and control electronics. The structure of the circuit and its components are explained:

D 1 = Fotoelement z. B. BPW 21
IC 1 = TCA 105 (Schwellenwertschalter) (Schmitt-Trigger)
IC 2 = FZK 101 (Monostabiler Multivibrator)
IC 3 = IC 2
IC 4 = FZH 101 (4 Stück NAND-Gatter)
R 1 = 10 kOhm
R 2 = 30 kOhm
C 1 = 500 µF
C 2 = 1000 µF D 1 = photo element z. B. BPW 21
IC 1 = TCA 105 (threshold switch) (Schmitt trigger)
IC 2 = FZK 101 (monostable multivibrator)
IC 3 = IC 2
IC 4 = FZH 101 (4 pieces of NAND gate)
R 1 = 10 kOhm
R 2 = 30 kOhm
C 1 = 500 µF
C 2 = 1000 µF

Das durch den Filter aus Spezialglas der Firma Schott, Mainz, (Filterwellenlänge 470 nm ± 10 nm) fallende Licht löst in dem Fotoelement (D 1) eine Spannung aus, die bei ca. 5000 1 × 400 mV beträgt. (Es kann sein, daß zum Erreichen dieses Schwell­ wertes ein einstufiger Transistorverstärker zwischen D 1 und IC 1 geschaltet werden muß, da das Filter einen nicht errechenbaren Einfluß auf die Lichtintensität nimmt. Dieser Einfluß konnte jedoch aus finanziellen Gründen nicht experimentell bestimmt werden.)The light falling through the filter made of special glass from Schott, Mainz, (filter wavelength 470 nm ± 10 nm) triggers a voltage in the photo element (D 1 ), which is approx. 5000 1 × 400 mV. (It may be that a single-stage transistor amplifier must be connected between D 1 and IC 1 to achieve this threshold, since the filter has an unpredictable influence on the light intensity. However, this influence could not be determined experimentally for financial reasons.)

Bei diesem Wert schaltet der Trigger (IC 1) durch und löst den Einschaltverzögerungsprozeß im IC 2 aus. Es handelt sich um einen monostabilen Multivibra­ tor. Das Relais zieht an und schaltet so die KFZ-Be­ leuchtung ein. Überschreitet der auf das Fotoelement fallende Lichtstrom den Level, so sperrt der Trigger, die Ausschaltverzögerung (IC 2) hält noch ca. 28 Sec. ein 1-Signal am Ausgang. Nach dieser Zeit erhält das Relais keinen Haltestrom mehr, die KFZ-Beleuchtung ver­ lischt.At this value the trigger (IC 1 ) switches through and triggers the switch-on delay process in IC 2 . It is a monostable multivibra tor. The relay picks up and switches on the vehicle lighting. If the luminous flux falling on the photo element exceeds the level, the trigger blocks and the switch-off delay (IC 2 ) lasts approx. 28 seconds. a 1 signal at the output. After this time, the relay no longer receives a holding current, the vehicle lighting goes out.

Aus Übersichtlichkeitsgründen wurden in der konkreten Schaltung 4 integrierte Schaltkreise verwendet.For reasons of clarity, the concrete Circuit 4 integrated circuits used.

Späterhin kann man jedoch hier mit einem IC auskommen, der vermutlich sogar bei entsprechender Stückzahl in der Automobil-Fertigung extra entwickelt wird.But later you can get by with an IC, probably even with a corresponding number of pieces in the Automobile manufacturing is specially developed.

Einen bereits selbst triggernden IC mit zwei monostabi­ len Multivibratoren stellt z. B. der Baustein SN74LS221 dar.An already self-triggering IC with two monostabi len multivibrators z. B. the block SN74LS221 represents.

Aber auch eine Schaltung mit diskreten Bauelementen wäre denkbar. But also a circuit with discrete components would be conceivable.  

Bild 3 zeigt schließlich die optimale Plazierung (1). Das fer­ tige Detektorelement, bestehend aus Fotodiode und Fil­ ter, (siehe Bild 4) wird in der Mitte am Unterrand der Frontscheibe von innen an die Scheibe geklebt. Die Kabel führen dann zu der hinter dem Armaturenbrett gelegenen Steuereinheit. Figure 3 shows the optimal placement ( 1 ). The finished detector element, consisting of a photodiode and filter (see Fig. 4), is glued to the inside of the pane in the middle on the lower edge of the front pane. The cables then lead to the control unit located behind the dashboard.

Der Detektor muß im Innenraum plaziert werden, um ein Verdunkeln durch Schmutz zu verhindern. Auch muß bei der Wahl der Plazierung darauf geachtet werden, daß der Detektor nicht durch Unachtsamkeit z. B. durch eine abge­ legte Zeitung verdeckt und damit das Licht eingeschaltet wird.The detector must be placed inside in order to Prevent darkening by dirt. Also must the choice of placement, care should be taken that the Detector not by carelessness z. B. by an abge put the newspaper face down and with it the light is switched on.

Bild 4 zeigt das zusammengebaute Detektorelement. In einem Kunststoffgehäuse (1) befindet sich das Fotoelement (2). Die Kabel werden nach unten herausgeführt. Mit Hilfe des Kleberandes kann ein schnelles und sauberes Plazieren an die Windschutzscheibe erfolgen. Das Filterglas (3) liegt also in einer künstlichen Vertiefung. Figure 4 shows the assembled detector element. In a plastic housing (1) is the picture element (2). The cables are led out downwards. With the help of the adhesive edge, a quick and clean placement on the windshield can be done. The filter glass ( 3 ) is therefore in an artificial recess.
