摘要

为了提高车辆的加速性能和爬坡性能，本文提出了一种新型的全电动汽车布局，由两个动力传动系统组成，每个动力传动系统都包括一个双速变速器。采用双速变速器允许八种不同的齿轮状态组合，增加了为每种操作条件选择高效率状态的可能性。设计了一种扭矩填充控制器，通过对另一轴的扭矩变化来补偿换挡时的扭矩间隙。最后，对该车辆布局的加速度、爬坡性和换挡性能进行了仿真分析，并与其他纯电动汽车配置进行了比较。

A Four-Wheel-Drive Fully Electric Vehicle Layout with Two-Speed Transmissions

This paper presents a novel fully electric vehicle layout, consisting of two drivetrains, each of them including a two-speed transmission, for improving vehicle acceleration and gradeability performance. The adoption of two-speed transmissions allows eight different gear state combinations, increasing the possibility of selecting a high-efficiency state for each operating condition. A torque-fill controller is developed for the compensation of the torque gap during gearshift through the variation of the torque on the other axle. Finally, a simulation-based analysis of the acceleration, gradeability and gearshift performance of this vehicle layout is discussed, in comparison with alternative fully electric vehicle configurations.
