摘要: 针对纯电动汽车换挡策略对不同驾驶风格的适应性较差,并且在复杂工况下容易出现 频繁换挡的问题,文章采用模糊控制的方法构建了一种综合换挡策略。首先,设计了传统的 动力性和经济性换挡策略,而后基于模糊控制理论构建了驾驶风格和驾驶意图识别模型。在 此基础上,提出了一种结合驾驶风格切换和驾驶意图修正的综合换挡策略。最后,通过搭建 AVL Cruise 和 Simulink 的联合仿真模型,在城市工况和新欧洲行驶循环(NEDC)工况下对 该换挡策略进行验证。仿真结果表明,所提出的综合换挡策略能够减少无效换挡次数,改善 驾驶体验,同时在保证经济性的前提下具备较好的动力性,提升了整车性能,满足多样化的 驾驶需求。

Abstract: Aiming at the problems that the gear shifting strategy of battery electric vehicles has poor adaptability to different driving styles and is prone to frequent gear shifting under complex working conditions, this article constructs a comprehensive gear shifting strategy by using the method of fuzzy control. Firstly, the traditional dynamic and economic shifting strategies are designed. Then, based on the fuzzy control theory, the driving style and driving intention recognition model is constructed. On this basis, a comprehensive gear shifting strategy combining driving style switching and driving intention correction is proposed. Finally, by building a joint simulation model of AVL Cruise and Simulink, the gear shifting strategy is verified under urban conditions and the new European driving cycle (NEDC) conditions. The simulation results show that the proposed comprehensive gear shifting strategy can reduce the number of invalid gear shifts, improve the driving experience, and at the same time, it has good power performance on the premise of ensuring economy, enhancing the overall vehicle performance and meeting diverse driving needs.
