Description
Die Erfindung betrifft eine Schaltungsanordnung für ein Kraftfahrzeug mit einer aufladbaren Batterie.The invention relates to a circuit arrangement for a Motor vehicle with a rechargeable battery.
Die Lebensdauer der aufladbaren Batterie ist begrenzt, insbesondere bei kalten Außentemperaturen reicht die Kapazität bei einer alten Batterie nicht mehr aus, um den Startvorgang durchzuführen. Der von der Batterie gelieferte Strom reicht nicht mehr aus, um den Anlasser motor des Kraftfahrzeuges zu bewegen. Das Fahrzeug kann nicht mehr angelassen werden, sondern ist liegengeblie ben.The life of the rechargeable battery is limited this is sufficient, especially in cold outside temperatures Capacity on an old battery is no longer around to carry out the starting process. The one from the battery delivered electricity is no longer sufficient to the starter motor of the motor vehicle to move. The vehicle can no longer be left on, but is left lying ben.
Aufgabe der Erfindung ist es, derartige Liegenbleiber zu verhindern.The object of the invention is to provide such beds prevent.
Die Aufgabe wird gelöst durch den Anspruch 1.The object is achieved by claim 1.
Erfindungsgemäß ist vorgesehen, daß der Batterie ein Kondensator parallel geschaltet ist. Dieser Kondensator ist in der Regel außer Betrieb. Stellt sich nun die oben genannte Situation ein, nämlich daß beim Anlassen der Anlassermotor nicht mehr durchdreht, da die Kapazität der Batterie nicht mehr ausreicht, den notwendigen Strom für den Anlassermotor zu liefern, wird über eine Logik schaltung der Kondensator parallel zur Batterie gelegt. Zugleich wird ein erneuter Anlaßvorgang für einen gewis sen Zeitraum unterbunden. According to the invention it is provided that the battery Capacitor is connected in parallel. This capacitor is usually out of order. Now faces the above mentioned situation, namely that when starting the Starter motor no longer spins because of the capacity the battery no longer has enough power Delivering for the starter motor is done through logic circuit the capacitor placed parallel to the battery. At the same time, a new starting process is certain prevented this period.
Damit kann die Restkapazität der Batterie in den Konden sator abfließen, mit dem schwachen Reststrom wird der Kondensator aufgeladen.This allows the remaining capacity of the battery in the condensers drain off, with the weak residual current the Capacitor charged.
Wird nach Freigabe des Anlassers, vorzugsweise etwa nach 15 bis 30 Sekunden, der Anlasser erneut betätigt, steht für den Anlassermotor der Strom zur Verfügung, der vom Kondensator geliefert wird, und zusätzlich der Strom, der von der Batterie geliefert wird. Da ein Kondensator in der Lage ist, seine in ihm gespeicherte Ladung sehr schnell abfließen zu lassen, ist somit für einen kurzen Zeitraum noch eine genügende Kapazität vorhanden, den Anlasser für einen ausreichenden Zeitraum, abhängig von der Kondensatorgröße, vorzugsweise mindestens ein oder zwei Sekunden, zu betätigen. Bei intaktem Verbrennungs motor reicht das aus, um das Fahrzeug zu starten, das Liegenbleiben aufgrund erschöpfter Batterie ist verhin dert. Zugleich jedoch hat der Fahrer damit ein deutli ches Warnsignal erhalten, daß er - schon im eigenen In teresse - umgehend die Werkstatt aufsuchen muß, um die alte und für einen Kaltstart nicht mehr ausreichende Batterie zu ersetzen.Will be after approval of the starter, preferably about 15 to 30 seconds, the starter is operated again for the starter motor the current available from Capacitor is supplied, and in addition the current, supplied by the battery. Because a capacitor is able to store its charge very much Letting it drain quickly is therefore for a short There is still sufficient capacity for the period Starter for a sufficient period of time, depending on the capacitor size, preferably at least one or two seconds to press. With combustion intact motor is enough to start the vehicle that Lying down due to exhausted battery is prevented different. At the same time, however, the driver has a clear ch Warning signal that he - already in his own In interest - must immediately go to the workshop to find out old and no longer sufficient for a cold start To replace battery.
Auch bei einer versehentlich entladenen Batterie, falls Verbraucher bei stillstehendem Fahrzeug unbeabsichtigt eingeschaltet geblieben sind, kann über den der Batterie parallel geschalteten Kondensator das Starten des Fahr zeugs nochmals möglich sein, solange keine Tiefentladung der Batterie stattgefunden hat, sondern eine Restspan nung erhalten geblieben ist, die zur Aufladung des Kon densators hinreichend ist.Even if the battery is accidentally discharged, if Unintentional consumers when the vehicle is stationary can be left on via the battery capacitor connected in parallel starting driving Stuff be possible again, as long as no deep discharge the battery has taken place, but a residual chip has been preserved, which is used to charge the Kon is sufficient.
In bevorzugter Weise erfaßt die Logikschaltung die Not wendigkeit, den Kondensator zuzuschalten, dadurch, daß sie die Spannung der Batterie mißt und feststellt, wenn diese Spannung unter einen vordefinierbaren Wert ab sinkt. Dieser vordefinierte Wert ist derart- daß er in der Regel nicht ausreicht, den Anlasser noch zu betäti gen.The logic circuit preferably detects the emergency maneuverability to connect the capacitor, in that it measures and determines the voltage of the battery when this voltage drops below a predefinable value sinks. This predefined value is such that it is in is usually not sufficient to actuate the starter gene.
Im folgenden wird die Erfindung anhand der Zeichnung be schrieben. Es zeigen:In the following the invention with reference to the drawing be wrote. Show it:
Fig. 1 das Schaltbild der erfindungsgemäßen Anord nung; und Fig. 1 voltage the circuit diagram of Anord invention; and
Fig. 2 ein Flußdiagramm, das die Funktion der Schal tung erläutert. Fig. 2 is a flow chart that explains the function of the scarf device.
Mit dem Bezugszeichen 10 ist eine übliche Fahrzeugbatte rie bezeichnet, die mit ihrem einen Anschluß 12 auf Mas se gelegt ist und mit dem positiven Anschluß 14 an Ver braucher geführt wird. Einer der Verbraucher ist die Lo gikschaltung 16, andere Verbraucher sind, da für die Er findung nicht erheblich, nicht dargestellt. Die Logik schaltung 16 steuert einen Kondensator 18 an, der mit seiner anderen Seiten ebenfalls auf Masse gelegt ist.With reference numeral 10 is a conventional Fahrzeugbatte rie referred that is set with its one terminal 12 on Mas se and is led to the positive terminal 14 on Ver consumer. One of the consumers is the logic circuit 16 , other consumers are not shown because it is not significant for the invention. The logic circuit 16 controls a capacitor 18 , which is also connected to ground with its other sides.
Dabei ist vorgesehen, daß die Logikschaltung 16 nur bei eingeschalteter Zündung mit Spannung versorgt wird, ist auch die Logikschaltung aktiviert. Somit wird eine stän dige Belastung der Batterie bei stillstehendem Fahrzeug verhindert.It is provided that the logic circuit 16 is supplied with voltage only when the ignition is switched on, the logic circuit is also activated. This prevents a constant load on the battery when the vehicle is stationary.
Von der Logikschaltung 16 führt ein Schalter 20 zum An lasser 22, der hier schematisch als Kasten dargestellt ist.From the logic circuit 16 , a switch 20 leads to the starter 22 , which is shown schematically here as a box.
Die Funktionsweise dieser Schaltung ist folgende: This circuit works as follows:
Mit der Betätigung des Anlassers 20 wird in der Logik schaltung 16 die Spannung gemessen, die am Pluspol 14 der Batterie 10 anliegt. Solange diese Spannung über einen definierten Grenzwert U₀ liegt, ist die Schal tungsanordnung im Normalbetrieb, in diesem Fall ist der Kondensator 18 mit seinem Pluspol nicht mit der positi ven Batteriespannung verbunden.With the actuation of the starter 20 , the voltage is measured in the logic circuit 16 , which is present at the positive pole 14 of the battery 10 . As long as this voltage is above a defined limit value U₀, the circuit arrangement is in normal operation, in this case the capacitor 18 is not connected with its positive pole to the positive battery voltage.
Liegt jedoch die in der Logikschaltung 16 gemessene Spannung beim Schließen des Schalters 20 unterhalb des Wertes U₀, wird der Anlasser 22 durch die Logikschaltung 16 gesperrt. Die Spannung unterhalb des Wertes U₀ reicht nicht mehr aus, um den Anlassermotor durchzudrehen, die Restkapazität der Batterie 10 würde dann über den ste henden Anlassermotor abfließen.However, if the voltage measured in the logic circuit 16 when the switch 20 is closed is below the value U₀, the starter 22 is blocked by the logic circuit 16 . The voltage below the value U₀ is no longer sufficient to crank the starter motor, the remaining capacity of the battery 10 would then flow away via the standing starter motor.
Statt dessen wird der Kondensator 18 der Batterie 10 pa rallel geschaltet, indem der Pluspol des Kondensators 18 an den positiven Pol 14 der Batterie gelegt wird. Damit kann die Batterie 10 den Kondensator 18 aufladen, ein Ladevorgang, der einige Zeit in Anspruch nimmt, da die Batterie "schwach" ist, sie also keine großen Kapazi tätsreserven hat. Jedoch wird ein Zeitraum von etwa t = 15 bis etwa t = 30 Sekunden ausreichen, um den Konden sator vollständig aufzuladen. Dieser Zeitraum t hängt natürlich auch von der Kapazität des Kondensators ab.Instead, the capacitor 18 of the battery 10 is connected in parallel by placing the positive pole of the capacitor 18 on the positive pole 14 of the battery. Thus, the battery 10 can charge the capacitor 18 , a charging process that takes some time because the battery is "weak", so it does not have large capacity reserves. However, a time period from about t = 15 to about t = 30 seconds will be enough to fully charge the capacitor. This time period t naturally also depends on the capacitance of the capacitor.
Danach wird der Anlasser wieder freigegeben, es ist also möglich, durch Schließen des Schalters 20 erneut den Anlassermotor 22 mit Strom zu versorgen. Dieser Strom wird nun wiederum genommen aus der Batterie 10, zudem steht aber die Kapazität des Kondensators 18 zur Verfü gung, und die darin gespeicherte Energiemenge kann ver hältnismäßig schnell abfließen, so daß kurzzeitig noch mal ein Stromstoß zur Verfügung steht, der ausreicht, um den Anlassermotor zu betätigen und das Motormanagement zu versorgen. Bei einer intakten Brennkraftmaschine reicht dieser Zeitraum von etwa ein bis zwei Sekunden der Anlasserbetätigung aus, um den Motor nochmals zu starten.After that, the starter is released again, so it is possible to supply the starter motor 22 with current again by closing the switch 20 . This current is now again taken from the battery 10 , but there is also the capacitance of the capacitor 18 available, and the amount of energy stored therein can flow away relatively quickly, so that there is again a brief current surge that is sufficient for the Operate starter motor and supply the engine management. With an intact internal combustion engine, this period of time of about one to two seconds of starter actuation is sufficient to restart the engine.
Es ist selbstverständlich, daß der Fahrer jedoch durch die Zwangswartepause einen deutlichen Hinweis erhalten hat, daß segne Batterie nicht mehr im Normalbetrieb ar beitet, sondern daß er vielmehr gut daran tut, umgehend eine Werkstatt aufzusuchen und die Batterie wechseln zu lassen, wenn er nicht endgültig liegenbleiben möchte.It goes without saying that the driver does, however the compulsory waiting break receive a clear indication has that bless battery ar no longer in normal operation works, but rather that he does it well, immediately go to a workshop and change the battery if he doesn’t want to stay put.
In einer weiteren Ausgestaltung der Erfindung wird der Kondensator 18 in gewissen zeitlichen Abständen kurzzei tig über die Logikschaltung 16 bei fahrendem Fahrzeug an Spannung gelegt. Diese Abstände können nach festen zeit lichen Vorgaben erfolgen, alternativ ist es auch mög lich, den zeitlichen Abstand dadurch zu steuern, daß je weils die Verbindung des Kondensators 18 mit dem Pluspol 14 dann stattfindet, wenn die Spannung über dem Konden sator 18 auf einen definierbaren Wert abgesunken ist. Damit wird erreicht, daß bei Abstellen des Fahrzeuges der Kondensator 18 bereits aufgeladen ist. Natürlich findet eine gewissen Selbstentladung des Kondensators 18 statt, wenn das Fahrzeug steht, da diese Selbstentla dungsrate jedoch verhältnismäßig langsam ist, ist, so fern das Fahrzeug nicht über einen sehr langen Zeitraum abgestellt ist, der Kondensator noch mit einer gewissen Grundaufladung versehen, wenn das Fahrzeug wieder ge startet wird, und für den Fall einer schwachen Batterie muß diese den Kondensator nicht mehr vom völlig entlade nen Zustand aufladen, sondern lediglich zusätzliche Ladung liefern, um den Kondensator auf seinen jetzt noch maximal möglichen Ladezustand zu bringen.In a further embodiment of the invention, the capacitor 18 is briefly applied to the logic circuit 16 with the vehicle in motion at certain time intervals. These distances can take place according to fixed time specifications, alternatively it is also possible to control the time interval in that the connection of the capacitor 18 to the positive pole 14 takes place when the voltage across the capacitor 18 is at a definable level Value has dropped. This ensures that the capacitor 18 is already charged when the vehicle is parked. Of course, there is some self-discharge of the capacitor 18 when the vehicle is stationary, but since this rate of self-discharge is relatively slow, so long as the vehicle is not parked for a very long period of time, the capacitor is still provided with some basic charge if that Vehicle is started again ge, and in the case of a weak battery, this no longer has to charge the capacitor from the completely discharged state, but merely has to supply additional charge in order to bring the capacitor to its maximum possible state of charge.
