Abstract

Electric vehicles (EVs) have developed rapidly in the past decade, with a heightened focus on the development of high-performance EVs in recent years. However, the contradiction between drive performance and efficiency of electric drive systems has not been adequately resolved. To provide a potential solution to this issue, a novel dual-motor coupling torque vectoring drive system (DCTVD) is proposed in this paper through exploring potentially optimal power coupling configurations of dual-motor drive units. Correspondingly, based on the multi-mode operation capability of the DCTVD, a parameter optimization method, a drive mode switching control strategy, and a torque vectoring control strategy are proposed and discussed in detail. After applying these methods and strategies, the energy-saving potential of the DCTVD is verified by simulation. Results under typical driving cycle tests indicate that the DCTVD, with the parameter optimization and drive mode switching control strategy, shows a significant energy-saving improvements compared to a traditional single-motor single-speed drive system. Additionally, results under turning conditions indicate that the DCTVD has an observable energy-saving effect under certain conditions with the torque vectoring control strategy.

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
