Abstract: To alleviate environment pollution and reduce energy consumption,the engine performance control of Parallel Hybrid Electric Vehicle (PHEV) was researched.Based on the testing data of engine operating efficiency,the most desirable controlling point was determined.By combining with control influence of motor,the operation curve fuzzy control strategy of engine was optimized.Simulation comparison analysis was conducted with software ADVISOR and electric assisted controlling strategy,and the results indicated that fuzzy control strategy which considered integrated control motor and engine could reduce fuel consumption and emission.Meanwhile,dynamic performance kept invariant.The research could further improve the level of energy conservation and emission reduction of HEV.

Key words: hybrid electric vehicle, engine, integration, fuzzy control, energy conservation and emission reduction
