Analysis of the control mode and economical running for HEV

Expensive cost of manufacture and exploiture almost conceal the advantage of saving fuel and low pollution for HEV.We have tested the HEV for each driving cycle by testing experiment on the road,researched the working process of engine,electromotor,storage battery on each driving cycle,at the same time predominated economical area of vehicle running for different driving cycle with energy monitor,keeping the essence and going the dregs are studied.
