Abstract: In order to accurately estimate the comprehensive range of pure electric vehicles during the design and development process, especially in the early stages of design and development, and guide the research and design of comprehensive range of pure electric vehicles. This article proposes a vehicle environment simulation model based on Simulink using real vehicle parameters to estimate the comprehensive range of pure electric vehicles under China light vehicle test cycle (CLTC) conditions. The results indicate that the simulation model operates within a complete driving cycle. The actual vehicle speed height follows the target vehicle speed, which can meet the real-time simulation of the vehicle following the CLTC driving conditions. The comprehensive range calculated by the simulation model has a smaller error compared to the actual range of the vehicle. Can accurately reflect the actual comprehensive range of pure electric vehicles. Compared with the traditional method that requires actual vehicle testing for comprehensive endurance mileage. It can provide reliable data basis for the design and development of pure electric vehicles, and guide the research and development of comprehensive range of pure electric vehicles in reverse, greatly reducing research and development costs.

摘要： 为了能够在纯电汽车设计研发过程中准确估算纯电汽车综合续航里程，尤其是设计研 发初期指导纯电汽车综合续航里程。文章提出一种根据实车参数基于 Simulink 搭建的整车环 境仿真模型，在中国轻型汽车行驶工况（CLTC）循环工况下估算纯电汽车综合续航里程。结 果表明，仿真模型在一个完整的驾驶循环工况内，实际车速高度跟随目标车速，可以满足仿 真车辆实时跟随 CLTC 循环工况行驶；仿真模型计算的综合续航里程与车辆真实续航里程相 比误差小，能够准确地反映纯电汽车实际综合续航里程；与传统需要实车测试综合续航里程 方法相比，能够为纯电车辆的设计研发提供可靠的数据依据，反向指导纯电汽车综合续航里 程的研发设计，大幅降低研发成本。
