摘要

考虑到目前纯电动汽车多速自动手动变速器(AMT)的换挡策略将稳态换挡与瞬态换挡过程分离，很难找到换挡质量、动力性能和驾驶经济性的全面提升。本文利用人工智能技术，从熟练驾驶员的经验和专家知识中获取训练数据，建立基于模糊神经网络(FNN)的T-S模型。采用双速AMT纯电动汽车模型，对模糊换挡策略的性能进行了研究。根据AMESim和SIMULINK的联合仿真结果，记录到的平均抖动值为10.006，而基于普通换挡计划的平均值为16.472。结果表明，基于fnn的调度充分反映了驾驶员追求换挡平稳性的换挡意图，同时在经济性能损失可忽略的情况下提高了车辆的动态性能。

Research on multi objective intelligent shifting schedule of electric vehicle AMT considering ride comfort and economy

Considering the current shifting strategy of multi-speed automatic manual transmission (AMT) separates the steady-state shifting from the transient shifting process in the pure electric vehicle, it is difficult to find a comprehensive improvement of shifting quality, dynamic performance, and driving economy. In this paper, taking advantage of the artificial intelligence technology, a fuzzy neural network (FNN) based T-S model is established via obtaining the training data from skilled drivers' experience and expert knowledge. A two-speed AMT pure electric vehicle model is used to investigate the fuzzy shifting strategy performance. According to the co-simulation results of AMESim and SIMULINK, the average jerk of 10.006 is recorded, compared to the value of 16.472 based on an ordinary shifting schedule. The results show that FNN-based schedule fully reflects drivers' shifting intentions in pursuing shifting smoothness, at the same time, improving vehicle dynamic performance with negligible economic performance loss.
