Abstract

Effective control strategy (EMS) is very important for high fuel economy, low emission and good driving performance of hybrid electric vehicles. First, the operation mode of parallel hybrid electric vehicles was analyzed and the rule-based EMS was introduced. Then the equivalent fuel consumption minimization strategy (ECMS) was modified by the variation of battery state of charge (SOC) and introduced to optimize the EMS. Finally, this EMS was implemented in JA1015 drive cycle and analyzed by advanced vehicle simulation software CRUISE. The simulation results indicate that the improved EMS reduces fuel consumption effectively by distributing the torque between engine and motor properly, and it also sustains the battery SOC in a proper range
