디젤 플러그인 하이브리드 자동차 연비평가 시뮬레이터 개발

Diesel engines have some advantages over gasoline engines. Diesel engines can produce more torque in low speed and have higher fuel efficiency and make less carbon dioxide. There have been many studies that improve fuel efficiency of diesel engines, and diesel hybrid system emerges as most practical method out of the studies. Plug-in Hybrid Electric Vehicles (PHEV) can recharge batteries from urban electric grid system. PHEV can drive with only motor for some distance, which increases fuel efficiency. To evaluate fuel efficiency of different types of diesel PHEV systems, important components of PHEV power split system have been modeled by MATLAB Simulink. Torque and efficiency characteristics of diesel engine and Motor/Generator uses resized actual experimental data. Batteries, Clutches, Transmissions have been modeled as equations. Finally a DCT TMED system has been composed by adding controller of each module to verify system modeling.
