Abstract
Description
Die Erfindung betrifft eine Generatorvorrichtung, welche einen Generatorregler, einen Generator, eine Gleichrichter-Brückenschaltung und einen Temperatursensor aufweist.The The invention relates to a generator apparatus comprising a generator controller, a generator, a rectifier bridge circuit and having a temperature sensor.
Stand der TechnikState of the art
Es ist bereits bekannt, die Komponenten einer in einem Kraftfahrzeug vorgesehenen Generatorvorrichtung vor einer Überhitzung zu schützen. Zu diesem Zweck ist ein Temperatur-Schwellenwert vorgegeben, der in einem Speicher hinterlegt ist. Dieser Temperatur-Schwellenwert wird mit einem von einem Temperatursensor abgeleiteten Temperatur-Istwert verglichen. Überschreitet der Temperatur-Istwert den Temperatur-Schwellenwert, dann werden geeignete Maßnahmen ergriffen, um eine Überhitzung der Komponenten der Generatorvorrichtung zu verhindern. Beispielsweise wird die Leistungsabgabe des Generators reduziert, indem die vom Generator bereitgestellte Gleichspannung reduziert wird.It is already known, the components of a in a motor vehicle provided generator device against overheating to protect. For this purpose is a temperature threshold specified, which is stored in a memory. This temperature threshold is compared with a derived from a temperature sensor temperature feedback. exceeds the actual temperature value will be the temperature threshold, then appropriate measures taken to overheat prevent the components of the generator device. For example the output of the generator is reduced by the output from the Generator supplied DC voltage is reduced.
Da der genannte Temperatur-Schwellenwert fest eingestellt ist und da bei der bekannten Vorrichtung die Isttemperatur nur an einer vorgegebenen Stelle der Vorrichtung erfasst wird, beispielsweise im Generatorregler, wird bei bestimmten Fahrzeugapplikationen die Leistungsabgabe des Generators bereits begrenzt, bevor es dazu kommt, dass gefährdete Komponenten, beispielsweise die Dioden der Gleichrichterbrücke, ihre Grenztemperatur überschreiten. Weiterhin kann es dazu kommen, dass bei anderen Fahrzeugapplikationen noch keine Begrenzung der Leistungsabgabe des Generators vorgenommen wird, obwohl gefährdete Komponenten bereits ihre Grenztemperatur überschritten haben.There said temperature threshold is fixed and there in the known device, the actual temperature only at a predetermined location the device is detected, for example in the generator controller, For certain vehicle applications, the power output of the Generators already limited before it comes to that endangered Components, such as the rectifier bridge diodes, exceed their limit temperature. Furthermore, it can do so come that with other vehicle applications still no limitation The power output of the generator is made, although at risk Components already exceeded their limit temperature to have.
Folglich führt eine feste Einstellung der Abregelschwelle dazu, dass bei bestimmten Fahrzeugapplikationen die Leistung schon in unkritischen Temperaturbereichen begrenzt wird, während bei anderen Fahrzeugapplikationen kein ausreichender Schutz der Komponenten der Generatorvorrichtung vor einer Überhitzung gegeben ist.consequently introduces a fixed setting of the regulation threshold, that in certain vehicle applications, the power already in uncritical temperature ranges is limited while in other vehicle applications insufficient protection of Components of the generator device from overheating given is.

der
Vorteile der ErfindungAdvantages of the invention
Eine Generatorvorrichtung gemäß der Erfindung weist demgegenüber den Vorteil auf, dass durch die Einstellbarkeit der Abregelschwelle von außen ein Schwellenwert vorgege ben werden kann, bei welchem der jeweiligen Applikation entsprechend die Komponenten der Generatorvorrichtung geschützt werden ohne sie in unkritischen Temperaturbereichen in ihrer Leistung einzuschränken.A Generator device according to the invention has In contrast, the advantage that by the adjustability the Abregelschwelle from outside a threshold PRE- ben can be in which of the respective application accordingly the components of the generator device are protected without restricting their performance in uncritical temperature ranges.
Beispielsweise können in einem Steuergerät die Daten eines Modelles hinterlegt sein, anhand welcher Temperaturzusammenhänge zwischen den einzelnen Komponenten der jeweils vorliegenden Generatorvorrichtung ermittelt und in einen jeweils zugehörigen Temperatur-Schwellenwert umgerechnet werden. Dieser wird dann dem Generatorregler über eine geeignete Schnittstelle zugeführt und vom Generatorregler im weiteren Betrieb der Generatorvorrichtung verwendet.For example can in a control unit the data of a model be deposited based on which temperature relationships between the individual components of the present generator device determined and in a respective associated temperature threshold be converted. This is then the generator controller via a suitable interface supplied and from the generator controller used in the further operation of the generator device.
Auf diese Weise kann für jede Applikation individuell ein optimaler Temperatur-Schwellenwert vorgegeben werden derart, dass einerseits ein rechtzeitiges Einleiten von Schutzmaßnahmen sichergestellt ist, aber auch eine maximale Leistungsabgabe des Generators so lange gewährleistet ist, bis der erfasste Temperatur-Istwert den individuellen Temperatur-Schwellenwert überschreitet.On this way can be optimally customized for each application Temperature threshold can be specified such that on the one hand ensuring the timely introduction of protective measures is, but also a maximum power output of the generator so long is guaranteed until the detected actual temperature value exceeds the individual temperature threshold.
Weitere vorteilhafte Eigenschaften der Erfindung ergeben sich aus deren beispielhafter Erläuterung anhand der Figur.Further advantageous properties of the invention will become apparent from the exemplary explanation with reference to the figure.

Diese Einstellbarkeit des Temperatur-Schwellenwertes bzw. der Abregelschwelle durch eine aus Sicht des Generatorreglers externe Vorgabe bietet im Vergleich zu bekannten Generatorvorrichtungen eine Qualitäts- und Leistungsverbesserung, da das Schutzverhalten applikationsspezifisch angepasst werden kann und die maximal mögliche Generatorausgangsleistung bis zum Erreichen des genannten Temperatur-Schwellenwertes zur Verfügung gestellt werden kann. Zusätzlich ergibt sich durch den Einsatz von Gleichteilen in verschiedenen Applikationen eine Kostenreduzierung.

In addition, results from the use of Similar parts in different applications reduce costs. Under the same parts are understood parts that without specific adjustments in different generator devices and / or in different ones Vehicle applications can be used, for example Generator regulators, rectifier diodes or the complete rectifier, End shields, ball bearings, rotor with excitation winding, etc ..
