Adaptive Power Management Strategy Based on Equivalent Fuel Consumption Minimization Strategy for a Mild Hybrid Electric Vehicle

An adaptive power management strategy (APMS) is developed for a mild hybrid electric vehicle (HEV) with belt-driven starter generator (BSG). The proposed APMS design is based on the equivalent fuel consumption minimization strategy (ECMS). According to the state of charge (SOC) of the battery, an adaptive fuzzy sliding mode control (AFSMC) is used to adaptively adjust the equivalence factor which is used to convert the electric power usage to the equivalent fuel consumption. Simulation results show that the proposed APMS can effectively improve the fuel economy for different driving cycles.
