本文提出了一种新型多模混合动力系统运行仿真与优化的系统模型。本文提出的混合动力结构采用了电动CVTmode的行星轮系和多种速比的铺轴齿轮，并在一个简单的结构中实现了六种工作模式。基于Simulink/Advisor平台，建立了多模混合动力变速器的详细部件级模型，并根据系统配置整合到整车模型中。建立整车控制策略，从燃油经济性和排放水平两方面对整车整体运行和各混合动力运行模式进行优化。利用所建立的模型对混合动力汽车系统在不同工况下的性能进行了研究，并以具有领先性能参数的现有市场模型为基准进行了测试。通过模型仿真，验证了所提出的混合结构是一种可行的混合设计。
This paper presents a systematic model for the operation simulation and optimization of a novel multi-mode hybrid powertrain. The hybrid configuration proposed in the paper features a planetary gear train for an electric CVTmode in addition to lay-shaft gears for multiple speed ratios and realizes six operation modes in a simple structure. Detailed component level models were established for the multi-mode hybrid transmission and integrated to the overall vehicle model according to the system configuration using the Simulink/Advisor platform. The vehicle control strategy was then established with the objective to optimize the overall vehicle operation and each hybrid operation mode in terms of fuel economy and emission levels. The performance of the proposed hybrid vehicle system was studied using the developed model under various operation conditions and benchmarked with a current market model with leading performance parameters. The proposed hybrid configuration shows substantial improvements over the benchmark and is validated as a viable hybrid design based on the model simulation.
