Vehicle Systems Integration Laboratory


The Vehicle Systems Integration (VSI) Laboratory offers unique capabilities to test, simulate, and evaluate engines, electric motors, and transmissions in conventional and hybrid powertrain configurations for vehicles ranging from light-duty cars to Class 8 trucks. The VSI Lab is changing the pace of powertrain development by performing prototype research and characterization of advanced systems on a component level.

The lab comprises a powertrain test cell with twin AVL 500 kW AC transient dynamometers and a component test cell – both share energy storage system emulation and dSPACE hardware-in-the-loop (HIL) real-time platform capabilities. The VSI Lab also features “X”-in-the-loop hardware evaluation of powertrain components and/or subsystems in virtual vehicle environments, where “X” represents any experimental component or subsystem.

Through the VSI Lab’s first industry CRADA partner, Meritor Inc., the lab is able to bridge modeling/simulation/analysis and controls development of prototype hardware in transient operation of the Meritor Class 8 tractor drivetrain. Other significant collaborations with the VSI Lab include DOE, EPA, the International Council on Clean Transportation, Eaton Corporation, California Air Resources Board, National Renewable Energy Laboratory, Argonne National Laboratory, and SAE International.
