Abstract
Description
Es gibt verschiedene Verfahren und Vorrichtungen, die mit Hilfe eines Signals melden, daß ein Element, z. B. des Fahrzeugs, in einem anormalen Zustand sich befindet: DP 24 13 780; 26 27 119; 38 28 634 u.a.There are various methods and devices that report with the help of a signal that an element, e.g. B. of the vehicle, in an abnormal condition located: DP 24 13 780; 26 27 119; 38 28 634 and others
Aber es gibt Elemente, wie die Beleuchtung des Fahrzeugs, wo das Signal nur sehr kurz wirkt (nur beim Aussteigen) und das Übersehen des Signals dazu führen kann, daß das nächste Anlassen des Motors fast unmöglich sein wird, weil der Akkumulator leer ist und eine mögliche Hilfe zu weit sein kann. Dabei ist eine zu vollständige Entladung des Akkumulators einfach schädlich.But there are elements like the lighting of the Vehicle where the signal is very short (only when getting out) and overlooking the signal can cause the next engine start almost will be impossible because the accumulator is empty and a possible help may be too far. It is the battery is too discharged simply harmful.
Die Beleuchtung des Fahrzeugs ist aber so ein Element, der ein Warnsignal nicht unbedingt braucht, weil die Beleuchtung einfach automatisch abgeschaltet werden kann. Das Signal, das das automatische Abschalten bewirkt, kann das Abstellen des Motors sein. Weil aber die Beleuchtung auch vor dem Anlassen des Motors oft vorhanden sein muß, muß die Möglichkeit bestehen, die Beleuchtung einzuschalten, auch wenn der Motor nicht läuft. Dies war das Ziel der Erfindung.The lighting of the vehicle is one Element that does not necessarily need a warning signal because the lights just turn off automatically can be. The signal that the automatic Shutdown causes the engine to stop be. But because the lighting also before starting of the engine must be present often, the possibility exist to turn on the lights, even if the Engine is not running. This was the aim of the invention.
Das Ziel ist mit Hilfe von Merkmalen des Anspruches 1 erreicht worden.The goal is with the help of features of the claim 1 has been achieved.
In diesem Falle braucht man bei dem Verlassen des Autos nicht nachprüfen, ob alles ausgeschaltet ist. Auch wenn man sehr vergeßlich ist, mit dem Akku passiert nichts, er bleibt aufgeladen.In this case you need to leave the Cars don't check that everything is turned off. Even if you are very forgetful, with the battery nothing happens, he remains charged.
Die Wirkungsweise und eine Variante der Vorrichtung sind schematisch auf der Fig. 1 dargestellt.The mode of operation and a variant of the device are shown schematically in FIG. 1.
Die Vorrichtung besteht aus einem Relais (Fig. 1), einem RC-Element, einem Gleichrichter GR und einem Knopf K. Der Kondensator C des RC-Elements ist durch den Gleichrichter GR mit dem Generator G verbunden (der zum Aufladen des Akkumulators dient). Der Widerstand R1 begrenzt den Strom, der durch den Gleichrichter GR fließen kann. Das Relais bekommt den nötigen Strom vom RC-Element, das während des Drückens des Knopfes K vom Akkumulator aufgeladen wird.The device consists of a relay ( Fig. 1), an RC element, a rectifier GR and a button K. The capacitor C of the RC element is connected by the rectifier GR to the generator G (which is used to charge the battery) . Resistor R1 limits the current that can flow through rectifier GR. The relay receives the necessary current from the RC element, which is charged by the accumulator when button K is pressed.
Wenn der Kondensator C aufgeladen ist (z. B. während des Drückens des Knopfes K), wird das Relais betätigt und die unterbrochene Leitung(en) sind damit wiederhergestellt. (Die unterbrochenen Leitungen und die Kontakte, die das Relais schließt, sind auf der Fig. 1 nicht gezeigt). Solange die Ladung des Kondensators C noch ausreichend ist, kann man das Licht jederzeit einschalten. Wie lange man dieses tun kann, definieren die Elemente R und C. Nach dieser Zeitlang (das können 2-10 Minuten sein oder auch mehr) werden die Kontakte wieder unterbrochen. Um die Leitungen wiederherzustellen, muß man den Knopf K von neuem drücken oder man muß den Motor anlassen. Während des Laufens des Motors bleibt das Relais immer betätigt, weil der Kondensator C ständig vom Generator G aufgeladen wird und damit kann auch die Beleuchtung jeden Moment eingeschaltet werden. Nach dem Einstellen des Motors bleibt das Relais noch eine Zeitlang betätigt (2-10 Minuten) und danach werden die Leitungen unterbrochen und die Entladung des Akkumulators A wird unmöglich.When the capacitor C is charged (e.g. while pressing the K button), the relay is actuated and the broken line (s) are thus restored. (The broken lines and the contacts that the relay closes are not shown in FIG. 1). The light can be switched on at any time as long as the capacitor C is sufficiently charged. How long you can do this is defined by the elements R and C. After this time (which can be 2-10 minutes or more) the contacts are interrupted again. To restore the lines, press button K again or start the engine. While the engine is running, the relay always remains activated because the capacitor C is constantly charged by the generator G and the lighting can thus be switched on at any moment. After the motor has been set, the relay remains activated for a while (2-10 minutes) and then the lines are interrupted and the discharge of the accumulator A becomes impossible.
Die Vorrichtung kann noch einen Schalter haben (auf Fig. 1 nicht gezeigt), mit dem die unterbrochenen Leitungen wiederhergestellt werden können (z. B., wenn es eine Forderung des TÜV sein wird).The device may also have a switch (not shown in Fig. 1) with which the broken lines can be restored (e.g. if it will be a requirement of the TÜV).
Die Vorrichtung kann auf verschiedene Weise ausgeführt werden. Wichtig ist nur, daß ein Zeitrelais vorhanden ist, und daß das Relais wenigstens solange betätigt bleibt, solange der Antriebsmotor läuft.The device can be implemented in various ways will. It is only important that there is a time relay and that the relay operates at least as long remains as long as the drive motor is running.
