Model-based fault simulation: A reduction method for the diagnosis of electrical components

Today's systems, for example motor vehicles, can be characterized by a variety of subsystems and components. For the automatic investigation of all possible breakdowns and the consequences thereof, an entire system simulation is inevitable. Without taking particular measures into account a variety of individual simulations are necessary in order to copy all the electrical error conditions of the subsystems or components. The necessary computing times for this are astronomical. In the following article a method is described which makes it possible to restrict the number of times the simulation is carried out to a practical number prior to the simulation.
