Study on mechanism of energy saving for double motor configuration hybrid electric vehicle

Compared with single-motor hybrid electric vehicle, the double-motor configuration has higher electric drive capability and driving efficiency, more powerful regulation and more energy-saving potential. Commencing from the structure, the energy-saving ideas and the advantage on energy-saving of the double-motor hybrid electric vehicles ,this paper studies the energy-saving efficiency of the double-motor hybrid electric vehicle and its advantage on energy-saving and builds the forward Co simulation model of HEV Theoretical study and simulation results show that the double-motor hybrid electric vehicle optimizes the engine´s operating points, improves the proportion of the time in the effective area for the engine and achieves excellent fuel economy.
