Energy Management Strategies for Hybrid Electric Vehicles
Energy Management Strategies for Hybrid Electric Vehicles
The energy management strategy in a hybrid electric vehicle (HEV) plays a very important role in the improvement of fuel economy and the reduction of emissions. This chapter discusses several practical and advanced energy management strategies of an HEV. A rule‐based energy management strategy is one of the most commonly used strategies in light to mild HEVs, especially in the early development stage. The chapter introduces a fuzzy logic control method, and presents a fuzzy‐logic‐based energy management strategy. Since the working state of the internal combustion engine (ICE) directly affects the fuel economy and emissions of an HEV, it is necessary to determine the optimal operational points specifically based on the HEV's driving characteristics. The chapter also introduces a two‐step optimization method for determining the optimal operational points for an HEV based on engine‐mapping data and the power requirements of practical drive cycles.
