摘　　要：针对某纯电动汽车在传统换挡策略下产生的频繁换挡问题,在AMT传统换挡控制策略研究的基础上,使用模糊控制以加速踏板开度和加速踏板开度变化率对驾驶员意图进行识别,然后结合驾驶员意图以及车速制定换挡策略。建立传统换挡策略和模糊控制驾驶员意图识别换挡策略的AMT换挡仿真模型。通过仿真结果的对比,验证模糊控制驾驶员意图识别的换挡策略的有效性。结果表明:对比传统换挡策略,模糊控制驾驶意图识别的换挡策略减少了换挡次数,经济性略有提升。Aiming at the frequent shifting problem of a pure electric vehicle under the traditional shifting strategy,based on the research of AMT traditional shift control strategy,fuzzy control is used to identify the driver's intention with the accelerator pedal opening and the rate of change of the accelerator pedal opening,and then the gear shift strategy is formulated based on the driver's intention and vehicle speed.The shift simulation model of AMT based on traditional shift strategy and fuzzy control driver intention recognition is established.Through the comparison of simulation results,the effectiveness of the shift strategy based on fuzzy control driver intention recognition is verified.The result shows that:compared with the traditional shift strategy,the shift strategy with fuzzy driving intention identification reduces the shift times and improves the economy slightly.
