Measuring Technique of Emission and Fuel Economy for HEV, PHEV

Abstract

The next-generation vehicles which include the Electric Vehicles and Hybrid Electric Vehicles (HEV) are researched and expected to reduce CO₂ emissions in the future. To evaluate the emission and fuel economy for the next-generation HEVs, the high accuracy certification test method is necessary. Therefore, new HILS (Hardware-In- the-Loop-Simulator) test method was produced. The new HILS system, which called the extended-HILS, was consisted of the real engine and the HILS, which was modeled by the virtual drive train and vehicle. In this report, the evaluation for the next-generation HEVs (for example, Plug-in HEV, HEV with the electrically heating catalyst) was introduced.
