Series Hybrid Electric Vehicle (SHEV) is a promising solution to reducing fuel consumption and emissions. It equipped with large battery packs that allow the SHEV first operates in full electrical mode, once the on-board batteries are depleted, the engine generator set turns on to sustain the power demand. Therefore, the efficiency and emissions of a SHEV depend heavily on the operation of the engine generator set. For the simultaneous power and emission control, the model based engine generator set control was developed. Then, emission estimation and Exhaust Gas Recirculation (EGR) model were implemented. The amount of EGR was determined based on the trade-off between NOx and soot emissions. Finally, Model Predictive Control (MPC) was designed and applied to control the power of the engine generator set at its operation point to achieve the best fuel economy as well as to satisfy the power demand.
