主 题：Dual motor transmission Operating mode Mode shift map Mode shift control Torque distribution Coordinated control
摘 要：As a vital vehicle part,the powertrain system is undergoing a fast transition towards *** new integrated electric drive system has been widely used,especially for passenger *** this work,a novel electric dual motor transmission is proposed for heavy commercial *** transmission scheme is firstly introduced,which can achieve 9 different operating modes including 5 single motor modes and 4 dual motor ***,the mode shift map with minimum energy consumption is designed based on the motor efficiency map and the proposed energy management *** driving power is appropriately distributed between the two motors in dual motor modes under the condition of minimum power *** addition,a coordinated control strategy is developed for mode shift control without power *** results show that the electric dual motor transmission has advantages in power consumption and power shift ability compared with the conventional single motor automated manual transmission.
