Abstract
Next-generation vehicles which include Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) are researched and expected to reduce CO₂ emissions in the future. High accuracy certification test method for next-generation HEVs is necessary in order to evaluate exhaust gas and fuel economy. In this research, new test bench system which responded to a complicated HEV powertrain system was produced. The bench system is able to reconstruct almost all of parallel HEV powertrain system in test room. The bench system is able to operate real internal combustion engine and real electric motor individually, and apply virtual drivetrain and vehicle. Therefore, the production of real vehicle is not needed for evaluation. The result of real-time simulation of HEV powertrain system in test bench is reported.
