Abstract
Description
Die vorliegende Erfindung betrifft ein System zum Ansteuern von Aggregaten bei Kraftfahrzeugen, insbesondere von Aggregaten („Sekundäraggregaten"), deren Funktion mit der Schaltung anderer Aggregate („Primäraggregate") verknüpft ist, wobei das Sekundäraggregat unabhängig von dem Schaltsignal für das Primäraggregat aufgrund einer Erkennung des Schaltzustandes des Primäraggregates geschaltet wird.The The present invention relates to a system for driving aggregates in motor vehicles, in particular of aggregates ("secondary units"), whose function associated with the circuit of other aggregates ("primary units"), the secondary aggregate independently from the switching signal for the primary unit due to a detection of the switching state of the primary unit is switched.
Zur Verringerung des Bedarfs an elektrischen Leitungen in Kraftfahrzeugen werden diese heute zunehmend mit Bus-Systemen ausgestattet, die neben einem „Power-Bus", der die Batteriespannung für die unterschiedlichen Aggregate bereitstellt, einen Steuersignalbus („Databus") aufweisen, über den mittels entsprechenden Signalcodierungseinheiten und Signalerkennungseinheiten über ein einziges Leitungspaar eine Vielzahl unterschiedlicher Steuersignale zu den unterschiedlichen Signalerkennungseinheiten gesendet werden. Die Steuersignale werden in den Signalerkennungseinheiten in Schaltsignale umgesetzt, die Aggregate mit aus der Batteriespannung gespeisten Arbeitssignalen verknüpfen. Als Steuerbus hat sich insbesondere der eingeführte CAN-Bus („Controller Area Network") neben anderen Bus- Systemen wie LAN-Bus, etc., durchgesetzt. Wesentlich für die Funktionsfähigkeit und Zuverlässigkeit von Data-Bus-Systemen ist, dass die von den Signalverarbeitungseinheiten erzeugten Data-Signale eindeutig von der jeweils durch sie adressierten Signalverarbeitungseinheit erkannt werden können. Neben einer vollständigen galvanischen Trennung des Bus von elektromagnetischen Einflüssen ist die Konstanz der Buskonfiguration Voraussetzung für eine sichere Signalübertragung und Signalerkennung.to Reduction of the need for electrical wiring in motor vehicles These are increasingly being equipped with bus systems today in addition to a "power bus", which is the battery voltage for the provides different aggregates, a control signal bus ("Databus") over which by means of corresponding signal coding units and signal recognition units via single line pair a variety of different control signals be sent to the different signal detection units. The control signals are in the signal detection units in switching signals implemented, the aggregates with fed from the battery voltage Link working signals. When Control bus has in particular the introduced CAN bus ("Controller Area Network ") next to other bus systems like LAN bus, etc., enforced. Essential for the functionality and reliability of data bus systems is that of the signal processing units generated data signals clearly from each addressed by them Signal processing unit can be detected. In addition to a complete galvanic Separation of the bus from electromagnetic influences is the constancy of the bus configuration requirement for a secure signal transmission and signal detection.
Problematisch ist es daher, Schaltfunktionen in das Bus-System zu integrieren, die nur temporär vorhanden sind, wie zum Beispiel Funktionen eines Anhängers an einem Kraftfahrzeug, insbesondere Funktionen, die simultan mit Funktionen des Kraftfahrzeuges stattfinden sollen, wie Blinker- und Beleuchtungsfunktionen, Einparkhilfen, oder auch elektrische Bremsfunktionen, ABS oder ESP, die der Anhängerstabilisierung dienen.Problematic It is therefore to integrate switching functions in the bus system, the only temporary available are, such as functions of a trailer on a motor vehicle, in particular functions that simultaneously with functions of the motor vehicle such as turn signal and lighting functions, parking aids, or also electric brake functions, ABS or ESP, the trailer stabilization serve.
