Matching and Optimization Algorithm of the Powertrain of HEV

Hybrid electronic vehicle （HEV） act as one of the most efficient solutions to the shortage of energy and environment pollution. Making full use of the power optimization of the two power sources, HEV can enhance the efficiency of the hybrid power system in an all round way. This paper introduces the parameter optimization and optimized algorithm of the hybrid powertrain, and comes to the conclusion that the power, economy and emission performances of the whole vehicle could be greatly polished by adopting rational optimized algorithms, pointing out that the matching and optimization of hybrid power system function as the highlight of the research and development of HEV and the optimization of hybrid power system is worth studying further.
