Description

Die Erfindung bezieht sich auf ein Verfahren zum funktionsgerechten Betrieb von elektrischen Komponenten in einem Kraftfahrzeug mittels eines zugeordneten Steuergerätes.The The invention relates to a method of functionally correct Operation of electrical components in a motor vehicle by means of an associated control unit.

Moderne Kraftfahrzeuge umfassen eine Vielzahl von elektrischen Komponenten wie beispielsweise, Sensoren oder Module, die durch Steuergeräte funktionsgerecht betrieben werden. Dabei variieren sowohl die elektrischen Komponenten als auch die Steuergeräte je nach Fahrzeugtyp bzw. Fahrzeugausstattung. Dies kann zu Problemen sowohl bei der Fertigung als auch im Feld, beispielsweise bei einem Austausch einer Komponente oder eines Steuergeräts führen. Es besteht die Gefahr, dass Komponenten und Steuergeräte nicht richtig zusammenarbeiten.modern Motor vehicles include a variety of electrical components such as, sensors or modules that function properly through control units operate. Both the electrical components vary as well as the controllers depending on vehicle type or vehicle equipment. This can cause problems both in production and in the field, for example in a Replace a component or a control unit. There is a danger that components and control devices not work together properly.

Bei der Fertigung ist, bedingt durch die Vielzahl von möglichen Kombinationen aus Steuergerät und Komponenten eine komplizierte Freigabesteuerung von Steuergeräten und deren Software erforderlich. Über die Modelllebenszeit erfordert die Verwaltung der maßgeblichen Programmparameter über die Gesamtzahl der Steuergeräte hinweg einen enormen Verwaltungsaufwand, der oft nicht vertretbar ist und enorme Kosten verursacht.at The production is due to the large number of possible Combinations of control unit and Components a complex release control of ECUs and their software required. about the model lifetime requires the management of the relevant Program parameters via the Total number of ECUs a huge administrative burden, which is often unreasonable is and causes enormous costs.

Beim Austausch einer Komponente kann es vorkommen, dass die neue Komponente in ihren Leistungsdaten von der vorhergehenden Komponente abweicht. Ihre Arbeitsweise entspricht dann in aller Regel nicht mehr den Erwartungen.At the Replacing a component can happen that the new component in their performance data deviates from the previous component. Your way of working then usually no longer corresponds to the Expectations.

Ein weiteres Problem ergibt sich dadurch, dass die elektrischen Komponenten in der Regel in ihren Leistungsdaten festgelegt sind. Ein Elektromotor, der für eine bestimmte Drehzahl ausgelegt ist und diese Drehzahl bei einer definierten Ausgangsspannung des Steuergeräts besitzt, kann diese Drehzahl in der Regel nicht steigern ohne Gefahr der Zerstörung zu laufen. Wird dieser Motor an einer Stelle verbaut, an der eigentlich eine höhere Drehzahl gefordert ist und liefert das Steuergerät weiter hin eine angenommen höhere Ausgangsspannung für einen Elektromotor, der diese höhere Drehzahl besitzt, droht die Zerstörung des verbauten Elektromotors.One Another problem arises from the fact that the electrical components usually defined in their performance data. An electric motor, the for a certain speed is designed and this speed at a has defined output voltage of the control unit, this speed can in usually not increase without risk of destruction to run. Will this Motor installed in one place, at the actually a higher speed is required and delivers the control unit continues to accept one higher Output voltage for an electric motor, this higher Speed possesses the destruction of the installed electric motor.

In diesem Zusammenhang ist es aus der EP 664 387 B1 und der DE 41 26 373 A1 bekannt, das Steuergerät im Bedarfsfall von extern zu programmieren bzw. eine gespeicherte Programmvariante auszuwählen. Dies setzt die Notwendigkeit voraus, eine derartige Programmänderung zu erkennen. Zudem ist der Aufwand erheblich.In this context, it is from the EP 664 387 B1 and the DE 41 26 373 A1 it is known to program the control unit externally if necessary or to select a stored program variant. This requires the need to recognize such a program change. In addition, the effort is significant.

Der Erfindung liegt das Problem zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, mittels derer das Zusammenwirken von elektrischen Komponenten und deren Steuergeräten optimiert wird.Of the Invention is based on the problem, a method of the initially to create said type, by means of which the interaction of electrical components and their control devices is optimized.

Die Lösung des Problems besteht in dem Verfahren, wie es im Patentanspruch 1 beschrieben ist. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution the problem consists in the method as defined in the claim 1 is described. Further advantageous embodiments of the invention emerge from the dependent claims.

Durch die Abfrage der jeweiligen Komponente hinsichtlich ihrer für den Betrieb relevanten Kenndaten durch das Steuergerät entfällt eine Einwirkung von außen. Das Kraftfahrzeug arbeitet insoweit autark. Unter der Annahme, dass die für diese Abfrage relevante Initialisierungsphase geeignet gewählt ist, und dass ggf. das Steuergerät die für den Betrieb der Komponente wesentlichen Steuerparameter ändert, kann ein fehlerhafter Betrieb der Komponente sicher vermieden werden.By the query of each component in terms of their for operation relevant characteristics by the control unit eliminates an external impact. The Motor vehicle works independently so far. Assuming that the for this query relevant initialization phase is suitably chosen, and that possibly the control unit the for can change the operation of the component essential control parameters a faulty operation of the component can be safely avoided.

Die Verwendung eines zugeordneten permanenten Speichers für die Kenndaten der Komponente machen das Fahrzeug unempfindlich gegenüber Bordnetzschwankungen oder -zusammenbrüchen.The Use of an assigned permanent memory for the characteristic data the component make the vehicle insensitive to electrical system fluctuations or breakdowns.

Das erfindungsgemäße Verfahren lässt sich bei einer oder auch bei mehreren Komponenten anwenden, die durch ein Steuergerät betrieben werden. In diesem Fall ist es besonders vorteilhaft, wenn das Steuergerät über einen Datenbus mit den Komponenten verbunden ist und diese Komponenten während der Initialisierungsphase der Reihe nach entsprechend abfragt.The inventive method can be included one or even several components, by a control unit operate. In this case, it is particularly advantageous if the control unit via a Data bus is connected to the components and these components while the initialization phase sequentially queried accordingly.

Wesentlich für die Erfindung ist auch der Beginn der Initialisierungsphase. Wird dieser durch das Wiedereinschalten der Stromversorgung bestimmt, ist sichergestellt, dass bei jedem Austausch einer Komponente oder des Steuergeräts selbst eine Initialisierung durchgeführt wird. Während eines derartigen Austauschs einer Komponente oder des Steuergeräts wird nämlich aus Sicherheitsgründen stets das Bordnetz abgeschaltet.Essential for the Invention is also the beginning of the initialization phase. Will this determined by the reconnection of the power supply, it is ensured that whenever you replace a component or the controller itself an initialization performed becomes. While such replacement of a component or the controller is namely for safety reasons always switched off the electrical system.

Schließlich wird das Handling der Komponenten innerhalb eines in der erfindungsgemäßen Weise betriebenen Gesamtsystems erleichtert, wenn die Kenndaten aus einem mit der Komponente mechanisch verbundenen Speicher (EEPROM) ausgelesen werden.Finally will the handling of the components within a manner according to the invention operated overall system facilitates when the characteristics of a with the component mechanically connected memory (EEPROM) read become.
