This paper presents a proper model of a HMMWV's four-speed automatic transmission powertrain. The model is simultaneously accurate enough to capture important powertrain transients and fast enough to run in real time. The model's parameters are scaled to match a powerful new diesel engine proposed for HMMWV propulsion. This enables real time hardware-in-the-loop engine testing and emissions measurement under realistic drive cycles. The algorithm used for proper powertrain modeling is easy to automate, which decreases the time needed to create simulation models for hardware-in-the-loop environments. Furthermore, the paper highlights the importance of scalability and validity in the context of proper modeling.
