Abstract

Die Erfindung betrifft ein Hybridmodell zur Modellierung eines Gesamtprozeßes in einem Fahrzeug bestehend aus zumindest einem physikalischen und einem neuronalen Teilmodell.The invention relates to a hybrid model for modeling an overall process in a vehicle consisting of at least one physical and one neural Partial model.

Um physikalisch schwierig zu beschreibende Prozeße zu modellieren, werden neuronale Netze in der Form eingesetzt, daß ein Prozeßanteil aus dem Gesamtprozeß ausschließlich mit dem physikalischen Modell simuliert wird, ein weiterer Prozeßanteil aus dem Gesamtprozeß ausschließlich mit dem neuronalen Modell simuliert wird und der Gesamtprozeß durch eine Zusammenführung der jeweils separat simulierten Prozesse beschrieben wird.In order to model processes that are physically difficult to describe, neuronal processes are used Networks used in the form that a process share from the overall process another part of the process is simulated only with the physical model simulated from the overall process exclusively with the neural model and the overall process by merging the separately simulated Processes is described.
