Abstract
Description
Die Erfindung betrifft einen Schalter und eine Schaltungsanordnung, die insbesondere zum Betreiben eines Starters eines Verbrennungsmotors vorgesehen ist und die einen solchen Schalter aufweist. The invention relates to a switch and a circuit arrangement, which is provided in particular for operating a starter of an internal combustion engine and having such a switch.
Stand der TechnikState of the art
Unter einem Schalter ist eine Baugruppe zu verstehen, die mittels elektrisch leitender Materialien eine elektrisch leitende Verbindung herstellt oder trennt. Typischerweise führt eine Betätigung des Schalters zu einem eindeutigen Schaltzustand, nämlich „offen“ oder „geschlossen“. Der durch die Verbindung fließende Strom wird durch den elektrischen Widerstand dieser Verbindung festgelegt. Schalter sind in elektrischen und elektronischen Schaltungen weit verbreitet. So werden Schalter bspw. in Schaltungsanordnungen zum Betreiben eines Starters eines Verbrennungsmotors eingesetzt. A switch is to be understood as meaning an assembly which produces or separates an electrically conductive connection by means of electrically conductive materials. Typically, an actuation of the switch leads to a clear switching state, namely "open" or "closed". The current flowing through the connection is determined by the electrical resistance of this connection. Switches are widely used in electrical and electronic circuits. For example, switches are used in circuit arrangements for operating a starter of an internal combustion engine.
Starter bzw. Anlasser werden zum Starten von Verbrennungsmotoren, bspw. in Kraftfahrzeugen, verwendet, wobei die Starter mit einer von der Kraftstoffversorgung getrennten Energieversorgung gespeist werden. Dabei kommen bspw. Elektromotoren zur Anwendung, die über eine Batterie, bspw. die Fahrzeugbatterie, betrieben werden. In vielen Fällen kommen Gleichstrommotoren zum Einsatz, deren Antriebsritzel zunächst in den Zahnkranz des Verbrennungsmotors einrückt, um danach den Verbrennungsmotor anzutreiben. Dies erfolgt z. B. mittels des Schub-Schraubtriebprinzips. Starters are used to start internal combustion engines, for example in motor vehicles, wherein the starters are fed with a separate from the fuel supply power supply. For example, electric motors are used which are operated via a battery, for example the vehicle battery. In many cases, DC motors are used, the drive pinion engages first in the ring gear of the engine to then drive the engine. This is done z. B. by means of the thrust Schraubtriebprinzips.
Nach dem Ende des Startvorgangs rückt das Ritzel typischerweise wieder aus dem Verbrennungsmotor aus. Dabei wird üblicherweise ein gemeinsames Relais für den Einspurvorgang und gleichzeitig für die Durchschaltung des Hauptstroms zum Antrieb des elektrischen Motors verwendet. Es ist zu beachten, dass bei einem Start/Stopp-System erhöhte Anforderungen gelten, da bei diesen der Starter häufiger genutzt wird. Ein Anliegen besteht darin, den Spannungseinbruch während des Startvorgangs zu minimieren, da dies dazu führt, dass weitere, von der Batterie versorgte Verbraucher, wie bspw. Steuergeräte im Kraftfahrzeug, nicht betriebsfähig sind. Dies ist insbesondere bei Fahrzeugen mit Start/Stopp-Funktion zu berücksichtigen, da durch den Ausfall von Steuergeräten ein sicherer Fahrbetrieb nicht gewährleistet werden kann.After the end of the starting process, the pinion typically moves back out of the engine. In this case, a common relay is usually used for the Einspurvorgang and at the same time for the switching of the main current to drive the electric motor. It should be noted that there are increased requirements for a start / stop system, as it uses the starter more frequently. One concern is to minimize the voltage dip during start-up, as this results in further, powered by the battery consumers, such as. Control units in the motor vehicle, are not operational. This is to be considered in particular for vehicles with start / stop function, since the failure of control units safe driving can not be guaranteed.
Aus diesem Grunde sollen Schalter entwickelt werden, die einen Startvorgang ohne übermäßigen Spannungseinbruch ermöglichen.For this reason, switches are to be developed, which allow a starting process without excessive voltage dip.
Offenbarung der ErfindungDisclosure of the invention
Vor diesem Hintergrund werden ein Schalter gemäß Anspruch 1 und eine Schaltungsanordnung mit den Merkmalen des Anspruchs 8 vorgestellt. Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen und der Beschreibung.Against this background, a switch according to claim 1 and a circuit arrangement with the features of claim 8 are presented. Embodiments result from the dependent claims and the description.
Der vorgestellte Schalter kann immer dann eingesetzt werden, wenn zumindest zwei verschiedene Widerstände in einem Schaltkreis bzw. in einer Schaltungsanordnung eingesetzt werden sollen.The presented switch can always be used if at least two different resistors are to be used in a circuit or in a circuit arrangement.
In Ausgestaltung kann eine Steuerung eingesetzt werden, die das Timing des Schalters steuert.In an embodiment, a controller can be used which controls the timing of the switch.
Mit der vorgestellten Schaltungsanordnung ist es nunmehr möglich, bei Betätigen des Schalters zu Beginn der Startphase eine Strombegrenzung und damit eine Begrenzung des Abfalls der Spannung an der versorgenden Batterie zu erreichen. Auf diese Weise ist sichergestellt, dass weitere, von der Batterie versorgte Verbraucher funktionsfähig bleiben. Dies ist insbesondere bei Fahrzeugen mit Start/Stopp-Funktion von Vorteil.With the presented circuit arrangement, it is now possible, upon actuation of the switch at the beginning of the start phase to achieve a current limit and thus a limitation of the drop in the voltage at the supplying battery. This ensures that other consumers powered by the battery remain functional. This is particularly advantageous for vehicles with start / stop function.
Dies wird bspw. dadurch erreicht, dass der elektrische Widerstand des Vorabwiderstands so gewählt ist, dass der über den geschlossenen Kontakt fließende Strom kleiner ist als der Strom, der zu einem späteren Zeitpunkt durch den elektrischen Widerstand des Hauptkontaktgebers ermöglicht wird. Zu dem genannten späteren Zeitpunkt können auch beide Kontaktgeber, die parallel oder in Reihe geschaltet sein können, den Strom bestimmen.This is achieved, for example, in that the electrical resistance of the preliminary resistance is chosen such that the current flowing through the closed contact is smaller than the current which is made possible at a later time by the electrical resistance of the main contactor. At the later time mentioned, both contactors, which can be connected in parallel or in series, can also determine the current.
Grundsätzlich ist es auch möglich, die Widerstände der Kontaktgeber so zu wählen, dass zunächst ein größerer Strom fließt. Es können auch mehr als zwei Kontaktgeber vorgesehen sein, die unabhängig voneinander zu bewegen sind. Auf diese Weise kann die Stromstärke mehrfach geändert werden.In principle, it is also possible to choose the resistors of the contactor so that initially a larger current flows. It can also be provided more than two contactors, which are to be moved independently. In this way, the current can be changed several times.
Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und den beiliegenden Zeichnungen.Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.
Es versteht sich, dass die voranstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.
