摘　　要：针对双速双离合变速器的电动汽车换挡控制,提出了一种基于规则的分区换挡策略,将经济性换挡策略与动态换挡策略相结合,以保证低能耗和强动力。利用模糊逻辑在线自适应调整分区换挡策略,引入模糊逻辑对换挡策略进行在线调整,减少无效换挡,提高变速器使用寿命,并验证了在线调整的效果。通过比较配置双速双离合变速器和单速主减速器的纯电动汽车经济性能和动态性能,表明配置双速双离合变速器的车辆具有更好的经济性能和动力性能,最后通过实验测试验证了其最大爬坡能力。A rule-based zoning shifting strategy is proposed for the shifting control of electric vehicles with dual speed dual clutch transmissions,which combines economic shifting strategy with dynamic shifting strategy to ensure low energy consumption and strong power.Using fuzzy logic to adaptively modify the partition shifting strategy online,introducing fuzzy logic to adjust the shifting strategy online,reducing ineffective shifting,improving the service life of the transmission,and verifying the effect of on⁃line adjustment.By comparing the economic and dynamic performance of pure electric vehicles equipped with a dual speed dual clutch transmission and a single speed main reducer,it is shown that vehicles equipped with a dual speed dual clutch transmission have better economic and power performance.Finally,their maximum climbing ability was verified through experimental testing.
