Abstract

Abstract Translated from German Die Scheinwerferanlage hat einen nach dem Prinzip der Abbildungsoptik wirkenden Abblendlicht-Scheinwerfer (11), dessen Lichtverteilung durch ein steuerbares Stellglied (23) veränderbar ist. Ein Sensor (16) leitet die registrierte Verkehrssituation (17) als Signal (20) einem elektronischen Rechner (21) zu, in welchem durch Vergleich mit gespeicherten Parametern (9) ein das Stellglied (23) steuerndes Ausgangssignal (22) erzeugt wird. Durch die Anpassung der Lichtverteilung an die unterschiedlichen Verkehrssituationen (17) wird ein optimales Fahrverhalten erreicht (Figur 1). The headlamp system has a low-beam headlamp (11) which operates on the principle of imaging optics and whose light distribution can be changed by a controllable actuator (23). A sensor (16) forwards the registered traffic situation (17) as a signal (20) to an electronic computer (21), in which an output signal (22) controlling the actuator (23) is generated by comparison with stored parameters (9). By adapting the light distribution to the different traffic situations (17), optimal driving behavior is achieved (FIG. 1).
