Abstract
Description
Die Erfindung betrifft ein Sicherungssystem für einen Laststromkreis, insbesondere für ein Kraftfahrzeug, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a fuse system for a load circuit, in particular for a Motor vehicle, according to the preamble of claim 1.

Will man eine Vielzahl von individuell steuerbaren Verbrauchern, wie in Kraftfahrzeugen absichern, wird der Aufwand für derartige Sicherungssysteme jedoch recht hoch.Want you have a variety of individually controllable consumers, like Secure in motor vehicles, the cost of such security systems but quite high.
Zwar könnte man auch eine zentrale Absicherung für eine Mehrzahl von Verbrauchern in Betracht ziehen, was jedoch aufgrund der unterschiedlichen Ansteuerzustände der einzelnen Verbraucher nur eine recht grobe Vorgabe summarischer Schwellwerte ermöglicht.Though could also a central protection for a majority of consumers However, due to the different driving conditions of the individual consumers only a very rough prescription summary Thresholds possible.
Aufgabe der Erfindung ist daher, ein Sicherungssystem vorzustellen, welches insbesondere für eine Mehrzahl von einzeln ansteuerbaren Verbrauchern geeignet ist.task The invention is therefore to provide a security system which especially for one Plural of individually controllable consumers is suitable.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Further developments can be found in the dependent claims.
So ist eine Sicherungssteuerung vorgesehen, welche in Abhängigkeit vom Ansteuerzustand der Verbraucher den Schwellwert automatisch anpasst. Als Ansteuerzustand ist natürlich zumindest das Zu- oder Abschalten der einzelnen Verbraucher zu berücksichtigen. Jedoch kann eine noch feinere Anpassung für Verbraucher mit Teillastbetrieb, wie elektrische Motoren, Klimaanlagen, Beleuchtungsanlagen oder dergleichen entsprechend dem jeweils vorgegebenen Teillast-Ansteuerzustand berücksichtigt werden.So a backup control is provided which depends on from the control state of the consumer, the threshold automatically adapts. As a driving state, of course, at least the supply or Shutdown of each consumer to consider. However, one can even finer adjustment for Consumers with partial load operation, such as electric motors, air conditioners, Lighting equipment or the like according to the respective predetermined Partial load driving condition taken into account become.
So kann die Information über den Ansteuerzustand selbst oder eine daraus abgeleitete Größe, beispielsweise ein entsprechender Stromsollwert an die Sicherungssteuerung übermittelt werden. Dadurch kann der Schwellwert viel genauer an die aus den aktuellen Ansteuerzuständen der Verbraucher resultierende Gesamt-Soll-Stromstärke angenähert werden und im Teillastbetrieb in einen Bereich gelegt werden, welcher unter der möglichen Maximallast liegt.So can the information about the driving state itself or a derived quantity, for example transmits a corresponding current setpoint to the backup control become. This makes the threshold much more accurate to those of the current activation states the consumer resulting total target current can be approximated and be placed in partial load operation in an area which under the possible Maximum load is.
Werden die Verbraucher von zumindest einem Steuergerät aus angesteuert, so übermittelt beispielsweise das Steuergerät den Ansteuerzustand der Verbraucher an die Sicherungssteuerung, beispielsweise über entsprechende Datenleitungen.Become the consumer controlled by at least one control unit, so transmitted for example, the controller the activation state of the consumers to the safety control, for example about corresponding data lines.
Alternativ bietet sich die Möglichkeit, daß die Sicherungssteuerung die Ansteuersignale an die Verbraucher erfasst und daraus den Ansteuerzustand dieser ableitet. So könnten beispielsweise die Ansteuersignale auf einem Datenbus durch die Sicherungssteuerung mitgehört werden.alternative offers the possibility that the backup control detects the control signals to the consumer and from this the drive state this derives. So could For example, the drive signals on a data bus through the Security control also heard become.
Vorzugsweise wird ein Stromfenster mit einem unteren Schwellwert und einem oberen Schwellwert für den Strom im Laststromkreis vorgegeben und das Trennelement aktiviert, wenn der Strom im Laststromkreis nicht zwischen diesen Schwellwerten liegt.Preferably is a stream window with a lower threshold and an upper one Threshold for set the current in the load circuit and activate the separator, if the current in the load circuit is not between these thresholds.
Durch dieses Stromfenster können weitere Störungsfälle im Laststromkreis erkannt werden, bspw. auch Lichtbogenbildung seriell in oder parallel zwischen Leitungen. Dies ist insbesondere für Kraftfahrzeuge mit höheren Bordnetzspannungen erforderlich.By this stream window can further faults in the load circuit be recognized, for example, arcing serially in or parallel between Cables. This is especially for motor vehicles with higher vehicle electrical system voltages required.
Zudem können engere Vorwarnschwellwerte vorgesehen werden.moreover can tighter pre-warning thresholds are provided.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen und einer Figur noch näher beschrieben.The Invention will be described below with reference to embodiments and a Figure described in more detail.

Entscheidend ist einzig die jeweils an den aktuellen Ansteuerzustand angepasste Bereitstellung entsprechender Schwellwerte und deren Nachführungcritical is only the respectively adapted to the current driving condition Provision of appropriate thresholds and their tracking
Die Strommeßanordnung misst dann den aktuellen Strom und kann durch die Dateninformation entscheiden, ob ein Kurzschluss, oder eine Überlast, oder ein paralleler oder auch serieller Lichtbogen vorliegt.The current measuring then measures the current current and can decide by the data information whether a short circuit, or an overload, or a parallel or serial arc is present.
Dies geschieht über ein Stromfenster, dass auf die aktuelle Last des Steuergerät angepasst wird. Es wird somit ein Minimalstrom und ein Maximalstrom festgelegt, in dem der aktuelle Strom des Sicherungselement liegen muss.This happens over a power window that matches the current load of the control unit becomes. It is thus set a minimum current and a maximum current, in which the current of the fuse element must be.
So erhöht sich bei einem parallelen Lichtbogen der Strom, muss aber nicht den Stromwert erreichen, welcher ein Auslösen eines konventionellen Sicherungselement, dass für den maximalen Strom des Steuergerät ausgelegt ist, zu folge hat. Dies gilt besonders, wenn nicht alle Lasten aktiv sind.So elevated in a parallel arc the current, but does not have to reach the current value which triggers a conventional fuse element, that for the maximum current of the control unit is designed to follow. This is especially true if not all loads are active.
Bei einem seriellen Lichtbogen verringert sich der Strom der aktuell fließen sollte. Ein herkömmliches Sicherungselement würde einen seriellen Kurzschluss nicht erkennen.at A serial arc reduces the current current flow should. A conventional one Fuse element would not recognize a serial short circuit.
Zudem können Warnsignale erzeugt werden, bspw. vorab bei Erreichen von Vorwarnschwellwerten, die ebenfalls in Abhängigkeit von den Ansteuerzuständen angepasst werden.moreover can Warning signals are generated, for example, in advance when reaching Vorwarnschwellwerten, which are also dependent from the drive states be adjusted.
