/ 87 SYSTEM INTEGRATION System integration is defined as the process of bringing together component subsystems into one system and ensuring the subsystems function together. System Integration without having prototype vehicles means frontloading by introducing tools and methods which reduce costs of in-vehicle testing by running them in a virtual environment. System integration in the virtual environment must consider typical functional aspects of road tests, e.g. how a driver interacts with the vehicle (powertrain) how the vehicle reacts to changes in environmental conditions. These interactions can be evaluated during virtual driving maneuvers. A high dynamic Powertrain in the Loop (PiL) testbed with a virtual vehicle-driver-road-infrastructure-traffic environment system generates real-world testing loads on the powertrain. The inertia of the dynamometers is key to achieving comparable loads. BENEFITS AT A GLANCE • Unmanned operation, 24/7 • Evaluation of specified strain limits and lifetime of the transmission case, gear teeth, bearings and clutch packs • Evaluation and optimization of component dimensioning • Maneuver Based Testing on a virtual proving ground with vehicle-like loads • Advanced Calibration for Driveability in an early development stage • Driveability Assessment without the need for a prototype vehicle • Emission Calibration without the need for a prototype vehicle
