Abstract
Description
Die Erfindung betrifft eine Steuervorrichtung für Fahrzeuge, insbesondere zur selbsttätigen Leuchtweiterregelung bei last- und fahrbedingten Karosserieneignungen.The invention relates to a control device for vehicles, especially for automatic headlamp leveling under load and driving-related body suitability.
Es sind Einstellvorrichtungen für die Leuchtweite bei Fahrzeugen bekannt, die eine mechanische Verstellung des Schein werfers an seinem Montagerahmen ermöglichen. Je nach Last kann zwischen zwei festgelegten Positionen umgeschaltet werden. Diese Art der Nachstellung ist umständlich und berücksichtigt die erforderliche Anpassung nur unzureichend. Weiterhin ist noch ein anderes System bekannt, bei dem die Nachstellung über einen manuell bedienbaren elektrischen Schalter im Fahrzeuginneren vorgesehen ist, welcher in drei Stufen auf einen elektrischen Nachstellantrieb des Scheinwerfers wirkt. Diese Korrektur der Leuchtweite bezieht sich ausschließlich auf lastabhängigen Blendschutz. Karosseriebewegungen bei Anfahrphasen und Bremsvorgängen oder Schaukeln bei schlechter Fahrbahndecke können mit diesem System nicht erfaßt werden. Die fahrbedingten Situationen werfen jedoch neben der Blendwirkung auch das Problem der eigenen Sicht verschlechterung auf, das mit dieser Vorrichtung nicht behebbar ist. Ein weiterer Nachteil liegt in der manuellen Bedienungen durch den Fahrzeugführer, da hierbei eine zweckbestimmte Handhabung nicht gesichert ist.There are adjustment devices for the headlight range in vehicles known that a mechanical adjustment of the bill allow thrower on its mounting frame. Depending on the load can be switched between two fixed positions. This type of adjustment is cumbersome and taken into account the necessary adjustment is insufficient. Another system is also known in which the Adjustment via a manually operated electrical Switch is provided inside the vehicle, which in three Steps on an electrical adjustment drive of the headlamp works. This correction of the lighting range relates exclusively on load-dependent glare protection. Body movements during starting phases and braking operations or swings with poor road surface can not with this system be recorded. However, the driving-related situations throw in addition to the glare, the problem of your own view deterioration on that cannot be remedied with this device is. Another disadvantage is the manual controls by the driver, as this is a dedicated one Handling is not secured.
Es war daher Aufgabe der Erfindung, eine Steuervorrichtung der eingangs genannten Art zu konstruieren, welche mit einfachen Mitteln eine zuverlässige Einrichtung darstellt, die alle Erfordernisse berücksichtigt.It was therefore an object of the invention to provide a control device to construct of the type mentioned, which with simple Means a reliable facility that all requirements taken into account.
Zur Lösung dieser Aufgabe ist die Steuervorrichtung der eingangs genannten Art erfindungsgemäß gekennzeichnet durch die Merkmale des Patentanspruches 1.To solve this problem, the control device is the beginning mentioned type characterized according to the invention by the Features of claim 1.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Further advantageous configurations are in the subclaims described.
Im folgenden wird eine bevorzugte Ausführungsform der Steuervorrichtung an Hand der Zeichnung erläutert. The following is a preferred embodiment of the control device explained using the drawing.

Die in den Figuren und dem Schaltbild dargestellte Steuer vorrichtung besteht und aus einem Schieberegister (10), im folgenden als Regler (10) bezeichnet, der fest in einem Gehäuse (1) installiert ist. Das Gehäuse (1) sowie der herausstehende in zwei Richtungen bewegliche Schieber (2) sind mit nicht dargestellten verschwenkbaren Montagewinkeln versehen, die an geeigneter Stelle mit der Karosserie (9) und der Achse (8) verbunden sind, so daß die durch Achsbewegung entstehenden Druck- und Zugkräfte auf den Schieber (2) wirken und der Regler (10) betätigt wird. Die dem Regler (10) über ein Zündschloß zugeführte und zur Vermeidung von Fehlfunktionen mittels Widerstand (6) und Zenerdiode (7) stabilisierte Betriebsspannung ermöglicht nunmehr die Abnahme einer Steuerspannung, die in ihrer Höhe abhängig von der Achsstellung ist. Um Ausregelungen durch Vibrationen des Fahrgestells oder zu kurzzeitige Impulse zu vermeiden, wird die Steuerspannung über einen Kondensator (3) eine bemessenen Trägheit unterworfen. Die weitere Zwischenschaltung eines Potentiometers (11) ermöglicht die Verschiebung der Steuerspannung und somit die Justierung der Grundeinstellung. Im folgenden Verlauf gelangt die Steuerspannung an den Servoantrieb der nicht im Detail dargestellten Auslenkvorrichtung, welche mechanisch mit dem Scheinwerfer gekoppelt ist.The control device shown in the figures and the circuit diagram consists of a shift register ( 10 ), hereinafter referred to as controller ( 10 ), which is permanently installed in a housing ( 1 ). The housing ( 1 ) and the projecting slide ( 2 ), which is movable in two directions, are provided with pivoting mounting brackets (not shown) which are connected at a suitable point to the body ( 9 ) and the axle ( 8 ), so that the pressure resulting from the axle movement - And tensile forces act on the slide ( 2 ) and the controller ( 10 ) is actuated. The operating voltage supplied to the controller ( 10 ) via an ignition lock and stabilized to avoid malfunctions by means of a resistor ( 6 ) and Zener diode ( 7 ) now enables a control voltage to be decreased, the amount of which depends on the axis position. In order to avoid adjustments caused by vibrations of the chassis or impulses that are too short, the control voltage is subjected to a measured inertia via a capacitor ( 3 ). The further interposition of a potentiometer ( 11 ) enables the control voltage to be shifted and thus the basic setting to be adjusted. In the following course, the control voltage reaches the servo drive of the deflection device (not shown in detail), which is mechanically coupled to the headlight.
Zur besseren Übersicht beschränkt sich die schematische Darstellung des Reglers (10) auf die Anordnung der Bauteile, die zur Vereinfachung der Montage im Reglergehäuse zu einer Funk tionseinheit zusammgefaßt sind. Mit Fig. 2 und Schaltbild (1) ist die technische Konzeption und Wirkungsweise ergänzend verdeutlicht.For a better overview, the schematic representation of the controller ( 10 ) is limited to the arrangement of the components, which are combined to simplify assembly in the controller housing to form a function unit. The technical concept and mode of operation are additionally illustrated with FIG. 2 and circuit diagram ( 1 ).
Fig. 2 zeigt in einfacher und übersichtlicher Darstellung die Befestigung des Reglers (10) mit einem Gehäuse (1) und dem Schieber (2) an Achse (8) und des im Schnitt veranschaulichten Karosserieblechs (9). Zusätzlich sind als Orientierungshilfe Rad und Federbein angedeutet. Fig. 2 shows a simple and clear representation of the attachment of the controller ( 10 ) with a housing ( 1 ) and the slide ( 2 ) on the axis ( 8 ) and the body panel ( 9 ) illustrated in section. The wheel and shock absorber are also indicated as a guide.
Schaltbild (1) vermittelt die funktionelle Konzeption der elektrischen Wirkungsweise.Circuit diagram ( 1 ) conveys the functional concept of the electrical mode of operation.
In der praktischen Ausführung der beschriebenen Steuervorrichtung ist die Kontrolle von zwei Achsen mit zwei elektrisch gegenläufig arbeitenden Reglern der einachsigen Regelung vorzuziehen.In the practical implementation of the control device described is the control of two axes with two electrically working in opposite directions Controllers over the uniaxial control.
