摘要/Abstract

摘要： 选择了配备电控机械式自动变速箱（AMT）的双电机混合动力汽车（HEV）作为研究平台，该平台可以部分甚至完全解决AMT不连续传输造成的换挡过程中动力中断问题。建立了HEV系统的简化动力学模型；分析了AMT降挡的过程和优点，提出了基于规则的降挡策略；最后在MATLAB/Simulink环境中进行了仿真测试。结果表明，换挡策略比不换挡策略油耗率降低16.8%。

Abstract: A dual-motor HEV equipped with an automatic manual transmission(AMT) was selected as the research platform. This platform might partially or even completely eliminate the power interruption problems caused by discontinuous transmission of AMT. A simplified dynamics model of the HEV system was established. The processes and advantages of AMT downshift were analyzed, and a rule-based downshift strategy was proposed. Finally, simulation tests were performed in the Simulink/MATLAB. The results show that the fuel consumption rate of the shift strategy is as 16.8% lower than that of the non-shift strategy.

Key words: regenerative braking, dual-motor, hybrid electric vehicles(HEV), shifting
