instrumentation and test systems ‹F›: What areas of the development platform does consistency refer to? ‹Conrad›: It refers to several core areas: these are simulation, test methods and data consistency. Where simulation models are concerned, it is very important to choose a modular structure, so that the models are scalable and able to be employed in differing environments. The second area involves the test methods themselves: here, there is a growing tendency to select real world usage scenarios, which are kept consistent across the entire testing process. The third level is data consistency, i.e. data once captured has to be usable throughout the entire process. ‹Voigt›: In this respect, models with real-time capability, where information can be transferred from the virtual to the real world, are of particular significance. The challenge here is to have exactly the right model 1 8 F o c u s Common Dataware, Modelware, Testware available at the right time and in the required quality. This requires the consideration of several approaches: On the one hand, there are models based on a modular structure where sub-models are simply replaced with actually existing components on the test beds. On the other hand, approaches are taken which involve deriving simplified, real-time capable models from more complex ones. Sometimes, semi-physical models are used too, i.e. physical models which are combined with data-driven models. Crucial to this is the consistency of model descriptions and parameterization data. ‹F›: Is it possible to assume that there is an increased blurring of boundaries between simulation and testing environment? ‹Conrad›: The combination of simulation and physical testing environment is the key to being able to validate concepts as early as possible. Today it is barely possible to specify a component without considering the overall system context, i.e. the load profile of an individual component can no longer be predicted without the system context. And in this respect, the interaction between simulation and testing is a very important factor. > Simulation modells, test methods and data are kept consistent across the entire development process. > Kai Uwe Voigt, Executive Vice President Instrumentation & Test Systems Models Test Cases Virtual World Real World Office Simulation MiL/SIL Testing HIL Testing Battery TestBed Testing Inverter TestBed Testing E-Motor TestBed Testing Engine TestBed Testing AWD TestBed Testing Chassis Dyno TestBed Testing Road Testing Common Processes
