Abstract

An electronic control device for a motor vehicle is proposed, which control device has a central means for connection to the electrical system of the vehicle, can be connected to at least one sensor and/or instruction transmitter and at least one actuator and/or one warning device and contains a resident memory. According to the invention, the control device contains all the operational functions and control characteristics for a multiplicity of different vehicles and/or vehicles which can be equipped differently in the aforesaid memory. The control device comprises means which permit it to detect the type and/or level of equipment of the respective vehicle via the central connection means and to activate the operational functions and control characteristics currently required for this from its memory. In this arrangement, the central connection means can be designed, inter alia, in such a way that it is capable of detecting encoding from a counterconnection means on the vehicle side. The control device can also itself learn its current peripheral connections in the vehicle as determined by a corresponding initialisation encoding via the central connection means.

Description

Die Erfindung betrifft ein elektronisches Steuergerät für ein Kraftfahrzeug nach der Gattung des Anspruchs 1.The invention relates to an electronic control unit for a motor vehicle according to the preamble of claim 1.

In Kraftfahrzeugen werden für verschiedenste Funktionen immer mehr elektronische Steuergeräte eingesetzt. Steuer­ geräte für gleiche oder vergleichbare Funktionen weisen je nach Fahrzeugtyp unterschiedliche Charakteristika auf. Infolgedessen müssen viele unterschiedliche Steuergeräte produziert und ersatzteilhalber vorgehalten werden.In motor vehicles are used for various functions more and more electronic control units are used. Tax have devices for the same or comparable functions different characteristics depending on the vehicle type. As a result, there are many different control units produced and kept on hand for spare parts.

Aufgabe der Erfindung ist es, ein elektronisches Steuergerät vorzuschlagen, durch welches die vorgenannte Lagerhaltungs­ problematik beseitigt wird.The object of the invention is an electronic control unit propose by which the aforementioned warehousing problem is eliminated.

Diese Aufgabe wird bei einem gattungsgemäßen elektroni­ schen Steuergerät mit den kennzeichnenden Merkmalen des unabhängigen Anspruchs 1 gelöst.This task is carried out in a generic electronics control unit with the characteristic features of the independent claim 1 solved.

Erfindungsgemäß vorteilhafte Weiterbildungen sind nach Lehre der abhängigen Ansprüche 2 bis 5 möglich.Advantageous further developments according to the invention are according to Teaching of dependent claims 2 to 5 possible.

Das erfindungsgemäße Steuergerät weist den Vorteil auf, daß es in größeren Stückzahlen als herkömmliche, ver­ schiedenartige Steuergeräte produziert werden kann, woraus sich erhebliche Kostenvorteile ergeben.The control device according to the invention has the advantage that it is in larger numbers than conventional, ver different types of control units can be produced, which results in considerable cost advantages.

Ein Ausführungsbeispiel des erfindungsgemäßen elektroni­ schen Steuergeräts ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the electronics according to the invention control unit is shown in the drawing and is described below.

Das Steuergerät 10 weist zwecks Anschluß an das Fahrzeug­ stromversorgungs- und Datenübertragungsnetz 12 ein Steck­ verbinderteil 11 auf, welches an ein fahrzeugseitiges Gegensteckverbinderteil 11.1 paßt. Des weiteren weist das Steuergerät 10 einen nichtflüchtigen Speicher 20 und verschiedene Eingänge 14a und 14b zur Zuführung von Sensor- oder Rückmeldesignalen und beispielsweise mehrere Ausgänge 15a, 15b zur Ansteuerung von Aktuato­ ren 16 und 17 oder Warneinrichtungen 18 auf. 13 bezeich­ net Sensoren, Abtastschalter zur Erfassung einer bei­ spielsweise durch Aktuatoren 16 und/oder 17 zu beein­ flussenden Stellung eines Gliedes, oder dergleichen.The control unit 10 has a connector part 11 for connection to the vehicle power supply and data transmission network 12 , which fits on a vehicle-side mating connector part 11.1 . Furthermore, the control device 10 has a non-volatile memory 20 and various inputs 14 a and 14 b for supplying sensor or feedback signals and, for example, a plurality of outputs 15 a, 15 b for controlling actuators 16 and 17 or warning devices 18 . 13 designates net sensors, scanning switches for detecting a position of a member, which is influenced by actuators 16 and / or 17 , or the like.

Es ist der Fall dargestellt, daß sich das Steuergerät 10 in einem Fahrzeug befindet, in welchem ausstattungs­ bedingt gar nicht alle möglichen Aktuatoren bzw. Sen­ soren vorhanden bzw. angeschlossen sind, weshalb die entsprechenden Leitungen 14b und 15b beispielsweise ohne Abschluß offen enden.It is the case that the control unit 10 is in a vehicle in which, due to equipment, not all possible actuators or sensors are present or connected, which is why the corresponding lines 14 b and 15 b, for example, end openly without conclusion.

Das Steuergerät 10 enthält in dem bereits erwähnten nicht­ flüchtigen Speicher 20 alle für verschiedene Fahrzeuge und deren verschiedene Ausstattungen in Frage kommenden Wir­ kungsfunktionen und/oder Steuercharakteristika abgelegt. Erst nach dem Verbinden des Steck- und Gegensteckverbin­ ders 11 und 11.1 und ggf. seiner Erstinbetriebnahme wird/werden davon die für das relevante Fahrzeug erforderli­ che/n Wirkungsfunktion/en und/oder Steuercharakteristika aktiviert. Dies wird dadurch erreicht, daß das Steuer­ gerät über seine Steckverbindung 11 die zu der entspre­ chenden Selektion erforderlichen Informationen vom Fahr­ zeug kodiert einliest. Dazu ist beispielsweise der Gegen­ steckverbinder 11.1 fahrzeug- und/oder ausstattungsspezi­ fisch codiert und der Steckverbinder 11 mit entsprechen­ den Erfassungsmitteln ausgestattet, etwa mit Abfragekon­ takten zur elektrischen Abtastung einer entsprechend ko­ dierten Verschaltung von Programmiergegenkontakten im Ge­ gensteckverbinder 11.1. oder das Steuergerät aktiviert aufgrund einer einfacheren Kodierung ein Programm, mit­ tels dessen es über seine Eingangsleitungen 14a, 14b und Ausgangsleitungen 15a, 15b spezifische Charakteristika der daran angeschlossenen Sensoren bzw. Aktuatoren bzw. Warneinrichtungen einliest, also z. B. deren Innenwider­ stand, um dann aus einem Vergleich der eingelesenen spe­ zifischen Kennwerte mit einer entsprechenden, im Steuer­ gerät 10 resident abgespeicherten Parametertabelle seine externe Beschaltung zu lernen.The control unit 10 contains in the non-volatile memory 20 already mentioned, all function functions and / or control characteristics that are suitable for different vehicles and their various equipment. It is only after connecting the plug-in and mating plug-in connectors 11 and 11.1 and, if necessary, starting it up for the first time that the effect function (s) and / or control characteristics required for the relevant vehicle are / are activated. This is achieved in that the control device reads in via its plug connection 11 the information required for the corresponding selection from the vehicle. For this purpose, for example, the mating connector 11.1 is coded in a vehicle and / or equipment-specific manner and the connector 11 is equipped with corresponding detection means, for example with interrogation contacts for electrical scanning of a correspondingly coded connection of programming mating contacts in the Ge connector 11.1 . or the control unit activates a program on the basis of a simpler coding, by means of which it reads in specific characteristics of the sensors or actuators or warning devices connected thereto via its input lines 14 a, 14 b and output lines 15 a, 15 b, B. whose internal resistance was then to learn its external circuitry from a comparison of the read-in specific parameters with a corresponding parameter table resident in the control device 10 .
