HIGHLIGHTS AND POSSIBILITIES Realistic Simulation of Driving Cycles with different Start conditions NEFZ Cycle with different charging status of the battery Different Possibilities to inject Faults / Errors Network: Failure of single ECUs / Components E-Motor: cut single phase Grid Supply: Phase failure, asymmetric phases, Peaks Bordnet: Voltage Drops caused from dynamic loads HV-Bordnet: Isolation fault, cable breaks Excellent Comparison between Emulation and especially in dynamic load scenarios High Performance Testing Dynamic switching between emulated and real component allows different use-cases to be tested e.g. driver selection switch for operating modes Markus Maier, RBM 06 November 2014 9
