由于环境和效率原因，混合动力电动汽车（HEV）引起了广泛关注。通常，混合动力汽车结合了两个动力传动系、一个传统动力源（例如汽油发动机、柴油发动机或燃料电池堆）和一个电力驱动系统（包括电动机和发电机），以产生比传统车辆具有更高燃油经济性的驱动力。此外，此类车辆不需要外部充电，因此可以在现有的加油基础设施内工作。 HEV的功率分流动力传动系配置具有串联型和并联型HEV动力系配置的各自优点。然而，需要复杂的控制系统来管理功率分流 HEV 动力传动系。设计这样的控制系统需要相当准确的 HEV 系统对象模型。为了开发串联和并联类型的动态设备模型，已经进行了大量研究，但功率分流 HEV 动力传动系的完整且经过验证的动态模型仍处于起步阶段。本文提出了一种功率分流动力传动系 HEV 动态模型，能够真实地复制不同驾驶条件下出现的所有主要稳态和瞬态现象。首先显示了该工厂模型及其组件的数学推导和建模表示。接下来，通过计算机模拟并与福特汽车公司测试跑道上的测试车辆实际测量的数据进行比较来进行分析、验证和验证。模型与实验结果之间的良好一致性证明了所导出的植物模型的保真度和有效性。由于该工厂模型是通过使用面向系统的方法和分层方法集成子系统模型来构建的，因此很容易更改子系统功能。开发的对象模型有助于分析和理解动力传动系统的主要动态、子系统和组件之间的相互作用以及由于运行状态变化和干扰影响而导致的系统瞬态。该工厂模型还可用于车辆系统控制器的开发、能源管理策略的评估、问题解决和编码算法的验证以及许多其他目的
Hybrid electric vehicles (HEVs) have attracted a lot of attention due to environmental and efficiency reasons. Typically, an HEV combines two power trains, a conventional power source such as a gasoline engine, a diesel engine, or a fuel cell stack, and an electric drive system (involving a motor and a generator) to produce driving power with a potential of higher fuel economy than conventional vehicles. Furthermore, such vehicles do not require external charging and thus work within the existing fueling infrastructures. The power-split power train configuration of an HEV has the individual advantages of the series and parallel types of HEV power train configurations. A sophisticated control system, however, is required to manage the power-split HEV power trains. Designing such a control system requires a reasonably accurate HEV system plant model. Much research has been done for developing dynamic plant models for the series and parallel types, but a complete and validated dynamic model for the power-split HEV power train is still in its infancy. This paper presents a power-split power train HEV dynamic model capable of realistically replicating all the major steady-state and transient phenomena appearing under different driving conditions. A mathematical derivation and modeling representation of this plant model and its components is shown first. Next, the analysis, verification, and validation through computer simulation and comparison with the data actually measured in the test vehicle at the Ford Motor Company's test track is performed. The excellent agreements between the model and the experimental results demonstrate the fidelity and validity of the derived plant model. Since this plant model was built by integrating the subsystem models using a system-oriented approach with a hierarchical methodology, it is easy to change subsystem functionalities. The developed plant model is useful for analyzing and understanding the dominant dynamics of the power train system, the interaction between subsystems and components, and system transients due to the change of operational state and the influence of disturbances. This plant model can also be employed for the development of vehicle system controllers, evaluation of energy management strategies, issue resolution, and verification of coded algorithms, among many other purposes
