Study on Forward-facing Model for Series Hybrid Electric Bus

Based on analyzing two basic modeling methods,this article build the forward-facing model for series hybrid electric bus(SHEB) and introduce the sub models in detail.Parameters of a certain SHEB are referred,and curves of dynamic property,economic performance and other important characters under china city drive cycle are derived.Comparing to the test data,the differences are acceptable,so this forward-facing model is correct and useful.
