摘要
纯电动汽车整车系统的开发研究涉及机械、电子、控制等多个学科,其多领域建模的过程不仅要求模型贴近系统实际,而且对子模型的集成能力提出了更高的要求。为提高模型的集成能力与仿真结果的可信性,采用一种适用于复杂系统的多领域建模语言Modelica,建立包括电池、永磁交流同步电机、悬架等纯电动汽车核心部件的整车仿真模型,并在多领域建模与仿真平台MWorks上对模型的车辆加速性能、爬坡能力、续驶里程、跟随性等进行了仿真,结果显示模型仿真数据与实车实测数据误差较小,表明所建整车模型的结构和参数是合理的。
Development of pure electric vehicle （PEV） system involves multiple disciplines, such as machinery, electronics, control etc. Its multi - domain modeling process not only requires model to be close to the practice of the system but also puts forward higher requirements to the integration ability of the model. To improve the integrated a- bility of the model and the credibility of simulation results, this paper adopts a more suitable language for complex system modeling - Modelica, and builds a simulation model of PEV which is composed of battery, AC permanent magnet synchronous motor, and suspension. Simulation analysis is conducted on the vehicle model about acceleration performance, grade ability, driving range and following features on the multi - domain modeling and simulation plat- form -MWorks. The results show that the error between the model simulation data and the real vehicle test data is quite small, which indicates that the structure and parameters of the vehicle model is reasonable.
