Abstract
In order to obtain synthetically advantages from the independent multiple-motors-driven system and the centralized single-motor-driven system, a novel centralized dual-motor-coupling powertrain (DMCP) system with a single row double pinions gear train for electric vehicle (EV) is proposed. By means of changing the drive modes, the proposed powertrain can satisfy the demands of different running conditions with high energy utilization efficiency. In this paper, the analyses on the mechanism structure and operating principles of the proposed powertrain are carried out firstly. Then, for further improving the operating efficiency and providing the effective ways for optimal matching design of the novel DMCP, the parameters sensitivity analysis is studied under the certain tested driving cycle based on a systematic simulation model. The simulation result shows that the energy consumption is increased by 3% as compared to the result of automobile test with the single motor powertrain.
