Together, they executed a to look at multiple attributesproject in which they virtually tested, simultaneously to find the optimalvalidated and calibrated an HEV main balance, says Bang Jae-Sung, seniorcontroller using a real-time, closed-engineer at Hyundai. Jae-Sung is one ofloop, model-based system simulation. the specialists at Hyundais R&D centerThough hardware in-the-loop (HiL) test who focuses on developing the HEVplatforms are industry-standard, this control logic for optimal vehicletest case was rather unique in that it performance. On top of that, with soaccurately captured both fuel economy many parameters involved and so manyand drivability simultaneously.different drive cycles to evaluate, it would become a very time-consumingHiL simulation can be a difficult and costly affair if too much of thebalancing task, says Jae-Sung. On one process still relied on trial and error. hand, you have to limit the number of The project we did with the Simcenter Engineering specialists showed us that we can realize a good correlation between results from HiL simulation and the real vehicle behavior for multiple attributes simultaneously.Bang Jae-Sung, Ph.D. Senior engineer R&D Center Hyundai Motor Company51'
