Abstract

The headlight system of a road vehicle is operated in a continuously variable mode such that the output lighting intensity is a function of ambient condition. The vehicle has ambient lighting sensors together with detection of the type of road terrain, e.g. inner city, country roads, motorway. The signals are removed by a controller that can be of a fuzzy logic type that implements knowledge based rules to determine power levels.

Description

An Kraftfahrzeugen sind Scheinwerfer angebracht, um einer­ seits die Umgebung besser zu sehen und um andererseits von anderen Verkehrsteilnehmern besser gesehen zu werden. Im Ver­ kehrsalltag tritt dabei nicht nur ein schleichender Übergang von Helligkeit zu Dunkelheit und umgekehrt auf, sondern der Helligkeitszustand ändert sich oft plötzlich, z. B. beim Durchfahren von Tunneln, beim Einbiegen von einer hell er­ leuchteten Straße in eine dunkle Nebenstraße, beim Fahren in und aus Parkhäusern oder beim Entgegenkommen anderer Fahr­ zeuge.Headlights are attached to motor vehicles to one on the one hand to see the surroundings better and on the other hand from to be seen better by other road users. In Ver Everyday sweeping is not just a gradual transition from light to dark and vice versa, but the Brightness often changes suddenly, e.g. B. at Driving through tunnels when turning into a bright he illuminated street in a dark side street when driving in and from parking garages or when accommodating other drivers witness.

Herkömmliche bekannte Scheinwerferanlagen an Kraftfahrzeugen reagieren nicht automatisch auf solche Umgebungsänderungen. Dies hat eine Energieverschwendung und eine erhöhte Unfallge­ fahr zur Folge, da die Scheinwerfer z. B. nach dem Verlassen einer häuslichen Tiefgarage nicht ausgeschaltet werden oder weil beispielsweise beim Abbiegen in eine schlecht beleuch­ tete Nebenstraße die dort herrschende Dunkelheit und die da­ durch bedingt erhöhte Unfallgefahr und potentielle Unfallop­ fer zu spät erkannt werden. Ein weiteres Problem mit erhöhter Unfallgefahr ist zu spät es oder ausbleibendes Abblenden beim Entgegenkommen von Fahrzeugen.Conventional known headlight systems on motor vehicles do not automatically react to such environmental changes. This wastes energy and increases the risk of accidents drive as the headlights z. B. after leaving a domestic underground car park cannot be switched off or because, for example, when turning into a bad light the side street the darkness prevailing there and the one there due to increased risk of accidents and potential accident victims be recognized too late. Another problem with increased The risk of an accident is too late or there is no dimming Accomodation from vehicles.

Schmidt-Clausen, ATZ 81 (1979), S. 439-450 sind zwar umgebungsadaptive Ansteuerungen für Scheinwerfer bekannt, die neben Mitteln zur Messung der Umgebungshellig­ keit z. T. auch weitere Sensoren aufweisen. Keiner dieser Schriften kann jedoch die zusätzliche Verwendung von Mitteln zur Detektion des Straßentyps entnommen werden, um die Be­ leuchtungsstärke auch in Abhängigkeit vom befahrenen Straßen­ typ zu steuern.From the published documents GB 21 56 515 A, DE 36 24 616 A1, DE 42 30 999 A1, DE 42 15 940 A1 and DE 40 40 175 A1 as also from H.-J. Schmidt-Clausen, ATZ 81 (1979), pp. 439-450 are environment-adaptive controls for headlights known, in addition to means for measuring the ambient brightness speed z. T. also have other sensors. None of these  Fonts, however, can use additional resources to be detected for the detection of the road type to the Be luminosity also depending on the traffic type to control.

Der Erfindung liegt daher die Aufgabe zugrunde, eine automa­ tische, umgebungsadaptive Ansteuerung für Scheinwerfer von Kraftfahrzeugen anzugeben, welche in der Lage ist, auf sich ändernde Beleuchtungsverhältnisse in der momentanen Umgebung automatisch zu reagieren und die jeweils optimale Beleuch­ tungsstärke und Beleuchtungscharakteristik der Scheinwerfer durch eine entsprechende Ansteuerung zu gewährleisten und dabei die Beleuchtungsstärke auch in Abhängigkeit vom befah­ renen Straßentyp zu steuern. The invention is therefore based on the object of an automa tables, environment-adaptive control for headlights from Motor vehicles indicate which is capable of on itself changing lighting conditions in the current environment automatically react and the optimal lighting intensity and lighting characteristics of the headlights to ensure by appropriate control and the illuminance also depends on the command control your street type.  

Diese Aufgabe wird durch eine umgebungsadaptive Ansteuerung für Scheinwerfer von Kraftfahrzeugen mit Merkmalen nach An­ spruch 1 gelöst. Bei dieser umgebungsadaptiven Steuerung für Scheinwerfer von Kraftfahrzeugen sind Mittel zur Messung der momentanen Umgebungshelligkeit sowie Mittel zur Detektion des momentan befahrenen Straßentyps (innerstädtische Straße, Landstraße, Autobahn, etc.) vorgesehen. Ferner sind Mittel zur optimalen Einstellung der Beleuchtungsstärke und/oder der Beleuchtungscharakteristik (z. B. Abblendlicht, Fernlicht) in Abhängigkeit von der gemessenen Umgebungshelligkeit und vom detektierten Straßentyp vorgesehen.This task is carried out by an environment-adaptive control for headlights of motor vehicles with features according to An spell 1 solved. With this environment-adaptive control for Headlights of motor vehicles are a means of measuring the current ambient brightness and means for detecting the currently used road type (inner-city road, Country road, highway, etc.). Furthermore, means for optimal adjustment of illuminance and / or Lighting characteristics (e.g. low beam, high beam) in Dependence on the measured ambient brightness and on detected street type provided.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.

Im folgenden wird die Erfindung anhand bevorzugter Ausfüh­ rungsbeispiele ausführlich beschrieben.In the following the invention is based on a preferred embodiment Example described in detail.

Die Notwendigkeit, Scheinwerfer an- oder auszuschalten bzw. auf- oder abzublenden kann nicht allein von der momentanen Umgebungshelligkeit abhängig gemacht werden, sondern muß sich auch am Straßentyp (Stadt, Überland, Autobahn) orientieren. Durch die Integration von Lichtsensoren mit einem geeigneten Straßenerkennungssystem kann eine intelligente Scheinwerfer­ steuerung erstellt werden. Bei einem bevorzugten Ausführungs­ beispiel der erfindungsgemäßen Steuerung ist daher eine per­ manente Ermittelung des aktuellen Straßentyps, wie sie z. B. in der Europäischen Patentanmeldung 93108427.1 vom 25.5.93, die diesen Anmeldungsunterlagen beigefügt wurde, beschrieben ist, vorgesehen und zur Ermittelung der optimalen Beleuch­ tungsstärke und Beleuchtungscharakteristik kann vorteilhaft ein mehrstufiges Fuzzy-System der folgenden Form eingesetzt werden:The need to turn headlights on or off or fading in or out cannot be done by the moment Ambient brightness must be made dependent, but must also orientate on the type of road (city, overland, highway). By integrating light sensors with a suitable one Road detection system can be a smart headlight control can be created. In a preferred embodiment example of the control according to the invention is therefore a per manente determination of the current road type, such as z. B. in European patent application 93108427.1 of May 25, 1993, which was attached to these application documents is provided and to determine the optimal lighting intensity and lighting characteristics can be advantageous a multi-stage fuzzy system of the following form is used become:

Ein System S0 ermittelt permanent den aktuellen Straßentyp (AST). A S0 system continuously determines the current road type (AST).  

In einem ersten Schritt ermittelt ein System S1 folgende Informationen:In a first step, a system S1 determines the following Information:

  • - ein Maß für die momentane durchschnittliche Umgebungshel­ ligkeit (DUH)- a measure of the current average ambient hel maturity (DUH)
  • - eine unscharfe Aussage darüber, ob sich das Fahrzeug momen­ tan in einer künstlich oder einer natürlich beleuchteten Umgebung befindet, d. h. ein Tupel (Beleuchtung, Sicher­ heit), wobei Beleuchtung einen Wert aus (Künstlich, Natür­ lich) und Sicherheit einen Wert aus [0 . . 1] annehmen kann. Sicherheit beschreibt die Sicherheit der Aussage (Wahrheitswert zwischen Null und Eins). Diese Informationen können aus dem Helligkeitsprofil (periodische Helligkeits­ schwankungen, Varianz der Helligkeit, Absolutwert der durchschnittlichen Helligkeit, . . . ) gewonnen werden.- a fuzzy statement about whether the vehicle is currently in motion tan in an artificially or naturally lit one Environment, d. H. a tuple (lighting, sure unit), whereby lighting has a value (artificial, natural Lich) and security a value from [0. . 1] can assume. Security describes the security of the statement (Truth value between zero and one). This information can from the brightness profile (periodic brightness fluctuations, variance in brightness, absolute value of the average brightness,. . . ) be won.

In einem zweiten Schritt wertet ein System S2 die Informatio­ nen AST, DUH (Beleuchtung, Sicherheit) sowie eigene intern aufgebaute, aus der Historie abgeleitete Größen wie z. B. mittlere Helligkeitsschwankung in der Weise aus, daß das System den Sollzustand der Scheinwerfer ausgibt (Sollzustand kann sein (AUS; ABBLEND; AUFBLEND)).In a second step, a S2 system evaluates the information AST, DUH (lighting, security) and internal built-up variables derived from history such as B. average fluctuation in brightness in such a way that the System outputs the target state of the headlights (target state can be (OFF; FADOW; FADOW)).

S2 kann als Fuzzy-System implementiert werden und damit leicht die unscharfe Information aus S1 verwerten. Beispiel­ haft werden einige Regeln (keineswegs vollständig) aus der Scheinwerfersollzustandsermittlungslogik angegeben:
wenn Beleuchtung = Künstlich und Sicherheit = hinreichend groß dann Licht = ABBLEND | AUFBLEND
wenn Beleuchtung = Natürlich und Sicherheit = hinreichend groß und DUH < Schwelle 1 dann Licht = AUS
wenn AST = Stadt dann Licht = AUS | ABBLEND
wenn AST = Autobahn oder AST = Überland und DUH < Schwelle 2 dann Licht = ABBLEND | AUFBLEND
wenn Beleuchtung = Künstlich und Sicherheit = hinreichend groß dann Licht = ABBLEND | AUFBLENDS2 can be implemented as a fuzzy system and thus easily utilize the unsharp information from S1. As an example, some rules (by no means complete) from the headlight target state determination logic are specified:
if lighting = artificial and security = sufficiently large then light = DIMMING | FASTENING
if lighting = natural and security = sufficiently large and DUH <threshold 1 then light = OFF
if AST = city then light = OFF | Dimming
if AST = motorway or AST = overland and DUH <threshold 2 then light = DIMMING | FASTENING
if lighting = artificial and security = sufficiently large then light = DIMMING | FASTENING

Der von S2 ermittelte Schweinwerfersollzustand kann in zwei Weisen verwendet werden:The target headlight condition determined by S2 can be split into two Ways to be used:

Die intelligente Scheinwerferansteuerung sollte so implemen­ tiert werden, daß der Kraftfahrer zwischen zwei Modi - im folgenden als AUTO bzw. PROP bezeichnet - wählen kann. Dabei bezeichnet der Modus AUTO ein völlig automatisches Ansteuern der Scheinwerfer und der Modus PROP einen Betriebszustand mit einer Anzeige des vorgeschlagenen Scheinwerferzustands im Cockpit. Ein manuelles Eingreifen seitens des Kraftfahrers ist dabei jeder Zeit möglich und führt das System automatisch vom Zustand AUTO in den Zustand PROP. Dadurch ist sichergestellt, daß eine bewußt vom Kraftfahrer gewünschte Scheinwerfereinstellung nicht von der intelligenten Schein­ werferansteuerung "korrigiert" wird.The intelligent headlight control should implement this be tiert that the driver between two modes - in hereinafter referred to as AUTO or PROP - can choose. Here AUTO mode denotes a fully automatic control the headlamp and the PROP mode with an operating status a display of the proposed headlight condition in Cockpit. Manual intervention by the driver is possible at any time and the system runs automatically from the AUTO state to the PROP state. This is ensures that one deliberately desired by the driver Headlight adjustment is not from the intelligent glow thrower control is "corrected".

Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist die automatische umgebungsadaptive Steuerung deshalb mit ei­ ner konventionellen Steuerung für die Scheinwerfer kombiniert und kann vom Bediener wahlweise zu- bzw. abgeschaltet werden.In a preferred embodiment of the invention the automatic environment-adaptive control therefore with egg a conventional control for the headlights combined and can be switched on or off by the operator.
