In
Die
Einrichtung zur automatischen Schaltung der Beleuchtungseinrichtungen
weist eine Sensoreinrichtung
Durch
die Steuereinrichtung
Die
Einrichtung zur automatischen Schaltung der Beleuchtungseinrichtungen
weist außerdem
eine Sensoreinrichtung zur Ermittlung der Sichtweite in der Umgebung
des Fahrzeugs auf. Durch die Sensoreinrichtung wird vorzugsweise
die Sichtweite in Fahrtrichtung vor dem Fahrzeug ermittelt. Vorzugsweise
wird für die
Ermittlung der Sichtweite dieselbe Sensoreinrichtung
Bei
optimalen Sichtbedingungen, das heißt bei großer Sichtweite, sind die Ergebnisse
der Kontrastmessungen zu den Zeitpunkten t1 und t2 zumindest annähernd gleich.
Bei schlechter Sicht, das heißt
geringer Sichtweite beispielsweise bei Nebel, Regen, Rauch oder
dergleichen ist der Kontrast zum Zeitpunkt t2 größer als zum Zeitpunkt t1. Auch
bei geringer Umgebungshelligkeit ist davon auszugehen, daß der Kontrast
zum Zeitpunkt t2 größer ist
als zum Zeitpunkt t1.
Der
erhaltene Meßwert
der Sichtweite δ ist
also völlig
unabhängig
vom realen Kontrast c0. Für
eine korrekte Auswertung der gemessenen Kontrastwerte ist folglich

die Messung ausgewählten
Objekts

der Bildverarbeitungseinrichtung
Der
vorstehend erläuterte
Ablauf zur Ermittlung der Sichtweite kann modifiziert werden, um
die Sichtweite δ mit
noch höherer
Genauigkeit ermitteln zu können.
Beispielsweise kann vorgesehen sein, daß nicht nur zwei Kontrastwerte

ausgewählte
Objekt

geeignete Objekte für
eine Messung zu finden, muß die

Wenn die Beleuchtungseinrichtungen ausgeschaltet sind, so werden diese durch die Einrichtung eingeschaltet, wenn entweder die Umgebungshelligkeit den Schwellwert S1 unterschreitet oder wenn die Sichtweite δ den Schwellwert S3 unterschreitet. Wenn die Beleuchtungseinrichtungen eingeschaltet sind, so werden diese nur ausgeschaltet, wenn sowohl die Umgebungshelligkeit den Schwellwert S2 überschreitet als auch die Sichtweite δ den Schwellwert S4 überschreitet.If the lighting devices are turned off, so will these turned on by the device when either the ambient brightness falls below the threshold value S1 or if the visibility δ the threshold value S3 falls below. When the lighting equipment is turned on are, they are only turned off when both the ambient brightness exceeds the threshold S2 as well as the visibility δ the Threshold S4 exceeds.
Zusätzlich kann auch vorgesehen sein, daß abhängig von der ermittelten Sichtweite δ die mögliche Höchstgeschwindigkeit des Fahrzeugs begrenzt wird. Wenn das Fahrzeug mit einer Geschwindigkeitsregelanlage ausgerüstet ist, so kann auch vorgesehen sein, daß durch diese automatisch der Geschwindigkeit des Fahrzeugs abhängig von der Sichtweite angepasst wird, das heißt mit abnehmender Sichtweite verringert wird.In addition, can also be provided that depends on the determined visibility δ the possible maximum speed of the vehicle is limited. If the vehicle is using a cruise control system equipped is, it can also be provided that automatically by this Speed of the vehicle adjusted depending on the visibility will, that is is reduced with decreasing visibility.
