Power Split Strategy of Plug-in Series Hybrid Electric Bus Based on Fuzzy Control

Article Preview

Abstract:

Plug-in hybrid electric vehicle has become a new global research and development hotspot with dual characteristics as electric and hybrid. Power split strategy influences fuel economy and emission performance. Selecting the plug-in series hybrid system used for bus as the research object, the power split and engine speed control strategy based on fuzzy control has been developed. The simulation results show that the strategy can improve the fuel economy and emission performance effectively.
