Abstract
Description
Die Erfindung geht aus von einer Vorrichtung zur redundanten Spannungsversorgung nach der Gattung des Anspruchs 1 und betrifft insbesondere eine solche Vorrichtung zür redundanten Spannungsversorgung in einem Kraftfahrzeugbordnetz.The The invention is based on a device for redundant power supply according to the preamble of claim 1 and in particular relates to a Such device zür redundant power supply in a motor vehicle electrical system.
Es ist bekannt, wichtige elektrische Verbraucher mit Hilfe einer redundanten Spannungsversorgung doppelt zu versorgen, damit bei einem Ausfall einer Spannungsversorgung die zweite die Spannungsversorgung sicher stellen kann und somit einen Ausfall des Verbrauchers vermeidet.It is known, important electrical consumers using a redundant Supply power twice, so in case of failure of a Power supply the second to ensure the power supply can and thus avoids a failure of the consumer.
Eine
solche redundante Spannungsversorgung wird auch bei wichtigen Verbrauchern
in einem Fahrzeugbordnetz durchgeführt. Beispielsweise wird in
einem in der
In
derzeit im Einsatz befindlichen modernen Kraftfahrzeugen werden
zunehmend auch die Versorgungsklemmen der Steuergeräte, beispielsweise die
sogenannte Klemme Kl.15 "Zündung" elektronisch mittels
eines Controllers gesteuert. Steuergeräte mit solch einer Klemmensteuerungsfunktion
sind als sicherheitskritisch anzusehen. Aus diesem Grund werden
zur Erhöhung
der Zuverlässigkeit
bestimmte Maßnahmen
notwendig. Diese Maßnahmen
umfassen beispielsweise:
Eine Notlauflogik zum Weiterbetrieb
der Klemmensteuerung bei Controllerausfall.In modern motor vehicles currently in use, the supply terminals of the control devices, for example, the so-called terminal Kl.15 "ignition" are increasingly controlled electronically by means of a controller. Control units with such a terminal control function are to be regarded as safety-critical. For this reason, certain measures are necessary to increase the reliability. These measures include, for example:
An emergency operation logic for the continued operation of the terminal control in case of controller failure.
Eine redundante Masseversorgung, beispielsweise über zwei sogenannte Klemme Kl.31-Anschlüsse.A redundant ground supply, for example via two so-called terminal Terminal 31 ports.
Eine redundante Batteriespannungsversorgung, beispielsweise über zwei sogenannte Klemme Kl.30-Anschlüsse.A redundant battery voltage supply, for example over two so-called terminal Kl.30 connections.

diese Maßnahmen

funktionsfähig
sind, wird in derzeitigen Kraftfahrzeugen beispielsweise eine typische
Versorgungstopologie eingesetzt, die in

Kurzschluss eines Kl.30-Kabels gegen Masse löst die Sicherung des entsprechenden
Kabels aus. Das Steuergerät
Durch die redundante Versorgung können Einfachfehler in der Versorgung zwar nicht zum Steuergeräteausfall führen, der Ausfall der redundanten Versorgung muss dem Benutzer jedoch immer mitgeteilt werden, um "schlafende Fehler" zu vermeiden. Hierzu ist eine interne Spannungsmessung an beiden Klemme Kl.30 Versorgungen notwendig.By the redundant supply can be single error In the supply, although not lead to control unit failure, the failure of the redundant supply however, must always be communicated to the user to avoid "sleeping errors". For this is an internal voltage measurement on both terminal Kl.30 supplies necessary.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Vorrichtung mit den Merkmalen des Anspruchs 1 hat gegenüber der bekannten Lösung den Vorteil, dass das komplett doppelte Vorhalten von zwei identischen Versorgungspfaden für ein Steuergerät bzw. einen sicherheitskritischen Verbraucher, die auf hohe Stromtragfähigkeit ausgelegt werden müssen, nicht mehr erforderlich ist. Dadurch lassen sich in vorteilhafter Weise die Gesamtkosten für Sicherungen, Kabel, Stecker und Dioden reduzieren. Erzielt werden diese Vorteile, indem die redundante Versorgung, insbesondere Spannungsversorgung, getrennt wird in eine Hauptstromversorgung des gesamten Steuergerätes bzw. des sicherheitskritischen Verbrauchers und die zusätzliche separate Versorgung der Notlauflogik sowie der Klemmentreiber.The device according to the invention with the features of claim 1 has the advantage over the known solution that the completely double provision of two identical supply paths for a control unit or a safety-critical consumer, which must be designed for high current carrying capacity, is no longer required. This advantageously reduces the overall costs of fuses, cables, connectors and diodes. These advantages are achieved by the redundant supply, in particular power supply is separated into a main power supply of the entire control unit or the safety-critical consumer and the additional separate supply of the emergency operation logic and the terminal driver.
Weitere Vorteile der Erfindung werden durch die in den Unteransprüchen angegebenen Maßnahmen erzielt. Dabei ist von Vorteil, dass durch eine separate VCC-Spannungsversorgung der Notlauflogik eine Erhöhung der Zuverlässigkeit erhalten wird, da Kurzschlüsse, die in der Controller-Versorgung auftreten, nicht zum Ausfall der Notlauflogik führen. Über eigene Dioden lässt sich die Notlauflogik und damit die gesamte Klemmensteuerung einfach und redundant mit Spannung bzw. Strom versorgen.Further Advantages of the invention are given by the in the subclaims activities achieved. It is advantageous that by a separate VCC power supply the emergency running logic an increase the reliability obtained because short circuits, which occur in the controller supply, not to the failure of the emergency operation logic to lead. About own Diodes leaves the emergency operation logic and thus the entire terminal control is easy and provide redundant power or voltage.
Die erfindungsgemäße Vorrichtung wird in besonders vorteilhafter Weise in Verbindung mit der Versorgung von Steuergeräten mit Klemmensteuerung bei sicherheitskritischen Aufgaben eingesetzt, insbesondere in Kraftfahrzeugen, wodurch bei Ausfall einer Klemme kein Ausfall von Licht, Motor, Servolenkung u.s.w. auftritt.The inventive device is in a particularly advantageous manner in connection with the supply of control units used with terminal control in safety-critical tasks, in particular in motor vehicles, which in case of failure of a terminal no failure of light, engine, power steering and so on occurs.
Bei einem auftretenden Kurzschluss kann durch Ansprechen der Sicherungen eine nachfolgende Gefährdung bzw. Zerstörung der eingesetzten Bauelemente vermieden werden und über eine Diagnoseschnittstelle eine Anzeige des aufgetretenen Fehlers durchgeführt werden.at An occurring short circuit can be triggered by the fuses a subsequent hazard or destruction the components used are avoided and over a Diagnostic interface an indication of the error occurred.

Der Versorgungspfad über die Notlaufklemme Kl.30N muss nur den Strom für die Notlauflogik und die Klemmentreiber tragen können. Über die Dioden D22 und D23 ist die Notlauflogik und damit die gesamte Klemmensteuerung redundant versorgt. Durch die separate Versorgung mit der geregelten Spannung VCC der Notlauflogik erhöht sich die Zuverlässigkeit, da Kurzschlüsse in der Controllerversorgung nicht zum Ausfall der Notlauflogik führen.Of the Supply path over The emergency terminal Kl.30N only has to supply the current for the emergency operation logic and the Can carry terminal drivers. About the Diodes D22 and D23 is the emergency logic and thus the entire terminal control supplied redundantly. Due to the separate supply with the regulated voltage VCC of the emergency running logic increases the reliability, because shorts in the controller supply does not lead to the failure of the emergency operation logic.
