Abstract

Process for operating electrical components in a vehicle comprises scanning the components using a control device during an initializing phase for ratings, reading out the ratings of the components from a storage unit permanently assigned to the components, transferring the ratings to the control device, and optionally changing the control parameters of the control device. Preferred Features: The control device is connected to several components via a data bus and scans these components during the initializing phase. The start of the initializing phase is determined by reconnecting the current supply. The ratings are red out from a storage unit (EEPROM) which is mechanically connected to the components.

Description

Die Erfindung bezieht sich auf ein Verfahren zum funktionsgerechten Betrieb von elektrischen Komponenten in einem Kraftfahrzeug mittels eines zugeordneten Steuergerätes.The invention relates to a method for the functional 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 For example, sensors or modules that function properly through control units operate. Both the electrical components and also vary the control units depending on the vehicle type or vehicle equipment. This can be too 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 controllers are not working properly together.

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.In the manufacturing is due to the variety of possible combinations of Controller and components a complicated release control of ECUs and their software required. Over the model life requires the administration the relevant program parameter over the total number of ECUs a huge administrative burden, which is often unreasonable and caused 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.When replacing a component, it may happen that the new component in their performance data deviates from the previous component. Your way of working then usually no longer meets 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 weiterhin eine angenommen höhere Ausgangsspannung für einen Elektromotor, der diese höhere Drehzahl besitzt, droht die Zerstörung des verbauten Elektromotors.Another problem arises from the fact that the electrical components in the Usually defined in their performance data. An electric motor for a specific Speed is designed and this speed at a defined output voltage has the control unit, this speed can not usually increase to run without danger of destruction. If this engine is installed in one place, on actually a higher speed is required and continues to supply the control unit an assumed higher output voltage for an electric motor, this higher speed, threatens 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 known from EP 664 387 B1 and DE 41 26 373 A1 known to program the control unit from external if necessary or a saved program variant to select. 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.The invention is based on the problem, a method of the aforementioned To create a way by which the interaction of electrical components and their control units 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 to the problem consists in the method as in claim 1 is described. Further advantageous embodiments of the invention will become apparent 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 querying the respective component with regard to its relevant for the operation Characteristics by the control unit eliminates an external impact. The Motor vehicle works independently so far. Assuming that for this query relevant initialization phase is suitably chosen, and that possibly the control unit changes the control parameters that are essential for the operation of the component, 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 associated permanent memory for the characteristics of 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 in one or even several components which are operated by a control unit. In this case is it is particularly advantageous if the controller via a data bus with the components is connected and these components during the initialization phase in turn polled 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 with each replacement of a component or the control unit itself a Initialization is performed. During such a replacement of a component or the controller is namely for security reasons always the Electrical system switched off.

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, the handling of the components within one in the invention Way operated overall system facilitates when the characteristics of one with the component mechanically connected memory (EEPROM) read become.
