There are numerous vehicle configurations in hybrid electricvehicles (HEV). What ’s more, the vehicle controls are verycomplicated. The premise of HEV to play the role of energysaving and environmental protection is to develop the optimalmatching method of Power-train Parameters. At present, onlythe power of each power-train demand are considered by thehybrid vehicle power system parameter matching method.Theworking point of the motor is not combined with the actualoperating condition of the vehicle, Therefore, the powerparameters of each power component determined by theconventional matching method are inefficient in the actualwork process, which affects the economic performance of thewhole vehicle[1,2,3].
