由于环保和效率等原因混合电动车辆(HEVS)已经具有很大的吸引力。一个典型的HEV由两个动力系统:一个是普通的动力源如一台汽油机、一台柴油机或一组燃料电池和一个电动系统(包含一台电动机和一台发电机)组成,它可能产生比普通车辆高的燃油经济性。而且,这样的车辆不需要外部充电,而在其内部存在燃料基本设施。HEV的功率分流动力系统构造的独特的HEV动力系统结构串联和并联型式的优点。但是操纵功率分流HEV动力系统要求一个完善的控制系统。设计这样的控制系统要有适当精确的HEV装置的平面模型。对于串联和并联型式的大量研究已经开发了许多动力平面模型。但一个完整的和有效的功率分流HEV动力系统的动力模型尚处于初期阶段。本文提出了在不同传动条件下可实际地和重复所有静态和瞬态现象的功率分流动力系统HEV的动力模型。首次表明了数学推导和这种平面模型和构件的表达,其次是通过计算机仿真分析、验证及性能鉴定和试验车辆在Ford公司性能道路试验实测进行比较。该模拟和实验结果的极好的吻合证实所引导的平面模型的精确性和正确性。因为该平面模型是综合用型谱方法论的系统定向子系统建立的,它很容易改变子系统的功率。开发该平面模型是用来分析和了解动力系的控制动力学,子系统和构件间的干扰以及由于工况和波动的影响的变化的系统瞬变。该平面模型也可用于车辆系统控制器的开发,能量管理战略的估价,结果的解析,编码算法的证明,及其中其他许多目的。
Hybrid electric vehicles (HEVs) have become very attractive due to environmental and efficiency reasons. A typical HEV consists of two powertrain systems: a common power source such as a gasoline engine, a diesel engine or a group of fuel cells and an electric system (including an electric motor and a generator) Vehicle high fuel economy. Moreover, such vehicles do not require external charging, and there are fuel infrastructures in their interior. HEV’s Power Split Power System Constructs the Unique Advantage of HEV Power System Structures in Series and Parallel Versions. But manipulating the power split HEV powertrain requires a complete control system. Designing such a control system requires a well-defined planar model of the HEV unit. A large number of studies on series and parallel versions have developed many power plane models. However, a complete and efficient power split HEV powertrain dynamic model is still in its infancy. This paper presents a dynamic model of a power split HEV that can actually and repeats all static and transient phenomena under different driving conditions. For the first time, mathematical derivation and expression of such planar models and components were demonstrated, followed by computer simulations, validation, and performance verification and comparison of test vehicle performance on Ford road tests. The good agreement between the simulation and experimental results confirms the accuracy and correctness of the guided planar model. Because the planar model is built using a system-oriented subsystem that integrates type-based spectral methods, it is easy to change the subsystem’s power. The plane model was developed to analyze and understand the powertrain’s control dynamics, subsystem and component interference, and system transients due to changes in conditions and fluctuations. This planar model can also be used in the development of vehicle system controllers, valuation of energy management strategies, interpretation of results, proof of coding algorithms, and many others among others.
