摘要：	DistributedDrive Electric Vehicles(DDEV)canachievethe best energy-savingrunning state of electric vehicle in real time.The driving efficiency characteristics of in-wheel motor have been achieved through in-wheel motor characteristics experiment,a-nalysis of the principle of vehicle energy-saving through optimal torque allocation was proposed.Combining the advantages of methods to improve the motor efficiency and motor response speed,optimized torque energy-saving allocation strategy was presented based on fuzzy weight coefficient,then optimized front axle torque allocation coefficient was obtained.Simulation and contrast analysis of vehicle energy consumption in vehicle driving cycle was carried on in ways of rear axle drive,average torque allocation and optimized torque energy-sav-ing allocation,the results show that the optimized torque energy-saving allocation strategy can decrease the energy consumption up to ap-proximately 0.058KJ and 0.117KJ per unit mileage comparing with the rear axle drive and average torque allocation.The road test also verified the energy-saving effect of the optimized torque energy-saving allocation algorithm.
