Study of Optimized Determination Method of HEV Engine Based on the High Frequency Working Area of Engine

Abstract:

A statistics method of the high frequency working area of engine (HFWA) was proposed based on the power required of engine. The power required of engine in different typical driving cycles were statistical analyzed. The weighting function of engine efficiency interval was defined according to the power required, then the degree of engine working efficiency Dm in typical driving cycles was calculated on the assumption of weighting function and efficiency. The more suitable engine of HEV was found by taking Dm as index. Through the simulation analysis and testing, the most economic engine was chosen from the optional engines.
