Description
Die Erfindung betrifft eine Vorrichtung zur Bordnetzstabilisierung bei Stopp/Startbetrieb.The invention relates to a device for on-board network stabilization during stop / start operation.
Bekannt ist eine Vorrichtung zur Bordnetzstabilisierung, in der mittels eines DC/DC-Wandlers ein Teilbordnetz stabilisiert wird.A device is known for On-board network stabilization, in which by means of a DC / DC converter Part-board network is stabilized.
Problematisch bei dieser bekannten Vorrichtung zur Bordnetzstabilisierung ist, dass entsprechend der Verbraucheranzahl und daraus resultierendem Leistungsbedarf die Vorrichtung teuer wird, da sie auf die Spitzenleistung ausgelegt werden muss. Zudem ist ein großer Aufwand für eine zusätzliche Verkablung des Teilnetzes vor allem bei vernetzten Fahrzeugen mit teilweise beliebiger Verteilung von Teilfunktionen auf viele Steuergeräte erforderlich.Problematic in this known Device for on-board stabilization is that according to the Number of consumers and the resulting power requirement the Device becomes expensive as it is designed for peak performance must become. Plus, it's a big one Effort for an additional Cabling of the subnet especially for networked vehicles with partial arbitrary distribution of sub-functions required on many control devices.

Das Ultracap-Modul liefert hierbei die für den Startvorgang benötigte hohe Leistung. Beim Bremsen wird über den Starter als Generator Energie zurückgewonnen und diese Energie direkt im Ultracap-Modul gespeichert. Diese Energie wird dem Bordnetz anschließend über den DC/DC-Wandler zugeführt. Das 14V-Bordnetz ist über den DC/DC-Wandler entkoppelt. Während des Startvorgangs werden die Fahrzeugbatterie und das Ultracap-Modul parallel betrieben. Somit können am Ultracap-Modul große Spannungshübe auftreten, ohne dass das Bordnetz großen Schwanlungen unterworfen ist, da das Ultracap-Modul Stromspitzen gegenüber der Fahrzeugbatterie und dem Bordnetz abpuffert.Finally, from "Big ..., Maxi ..., Ultracap, Cyclic Storage for the 42 V electrical system "from Dr. Hartmut Michel and Bernd Staib, Electronics 2/2002, known, an ultracap module parallel to the starter and parallel via a DC / DC converter to switch to a vehicle battery. The Ultracap module delivers here the for needed the boot process high performance. When braking is about the starter as a generator Energy recovered and this energy is stored directly in the Ultracap module. This energy will then via the DC / DC converter fed. The 14V electrical system is over the DC / DC converter decoupled. While the startup procedure will be the vehicle battery and the ultracap module operated in parallel. Thus, you can great on the ultracap module voltage swings occur without the electrical system subjected to large swings is because the ultracap module has power surges over the vehicle battery and buffers the electrical system.
Auf diese Weise können mit den herkömmlichen Spannungsstabilisierungen extreme Spannungsschwankungen ausgeglichen wer den, indem eine zusätzliche Energieversorgung während des Startvorgangs zugeschaltet wird. Jedoch ist diese Spannungsstabilisierung für sensible Verbraucher, d.h. Verbraucher, die stark spannungsabhängig sind, d.h. beispielsweise Komfortverbraucher wie die Beleuchtung, nicht ausreichend.This way, with the conventional Voltage stabilization compensates extreme voltage fluctuations who by adding an extra Energy supply during the startup process is switched on. However, this voltage stabilization is for sensitive Consumers, i. Consumers who are strongly voltage dependent, i. For example, comfort consumers such as lighting, not sufficient.

In den Unteransprüchen sind vorteilhafte Weiterbildungen der Erfindung angegeben.According to the invention this object is achieved by a Device for on-board network stabilization with the features of claim 1 or 7 solved. In the dependent claims advantageous developments of the invention are given.
Dazu wird erfindungsgemäß zumindest ein zusätzlicher Energiespeicher im Bordnetz zur Stützung der Versorgungsspannung sensibler Verbraucher genutzt, und/oder der Starter entkoppelt und der durch ihn im Bordnetz verursachte Spannungseinbruch dadurch reduziert oder vermieden.At least according to the invention an additional one Energy storage in the electrical system to support the supply voltage used by sensitive consumers, and / or the starter decoupled and the voltage drop caused by it in the electrical system thereby reduced or avoided.
Besonders vorteilhaft an der erfindungsgemäßen Lösung ist es, dass diese skalierbare Lösung auch dezentral einsetzbar ist. Dadurch ergeben sich Kostenvorteile bei allen bekannten Steuergeräte-Architekturen durch Wegfall einer Zusatzverkabelung. Außerdem können vorhandene Komponenten mehrfach genutzt werden.Particularly advantageous in the inventive solution it, that scalable solution too can be used decentrally. This results in cost advantages all known ECU architectures by omitting an additional cabling. In addition, existing components be used several times.
