摘要日益严重的环境和经济问题促使城市交通向着清洁、高效和可持续的方向发展。混合动力汽车在不降低动力性的前提下可大幅提高燃油经济性及减少汽车排放,混合动力汽车也越来越被消费者们所看重,因此研究这类车具有重要意义。本文依托依维柯 4x2 柴电混合动力客车项目,对宝迪柴电混合动力客车进行整车建模与仿真分析。 在相关文献基础上,先简要介绍了混合动力车的发展现状,接着介绍了混合动力车的构造,课题来源和本文的主要研究内容,其次根据设计要求确定混合动力电动汽车动力系统的结构为并联式,然后对车内的部件如电机,电池等进行参数化计算和选型,提出整车的控制方案。在 matlab平台下advisor 上进行建模,进行仿真时,需要确定发动机、电池、电机等特征参数并设置仿真时的参数。为了确定实际运行状况,提出了整车控制策略。 从仿真结果得到的整车燃油经济性,动力性等都达到了设计目标,并且能够完成相应的控制策略,可以实现发动机、电机的起停,制动能量回收,并保证电池soc保持在合理范围内。实验表明,本文的建模仿真方法合理有效。 59705 毕业论文关键词 混合动力汽车 建模仿真 advisor 电辅助控制策略
Title Power Daily Diesel-Electric Hybrid Buses Simulation Analysis
Abstract Increasingly serious environmental and economic problems have prompted urban traffic to be clean, efficient and sustainable. Hybrid vehicles without reducing the power can significantly improve fuel economy and reduce emissions from vehicles. Hybrid vehicles have been identified as the most current electric vehicles prospects for industrialization and marketization. Therefore,it is very important to study these cars.This paper relies on the Iveco 4x2 diesel-electric hybrid bus project, Power Daily diesel-electric hybrid bus vehicle modeling and simulation analysis. The analysis of the structure of hybrid vehicles, development, control strategy, and the subject of sources on the basis of the literature.This article describes significance and main contents of articles. Then we determine the structure for parallel according to the design requirements, selection and calculation, and the important parameters of the main components of the power system as a whole matching program.The Advisor platform is for modeling and simulation.In the simulation process,it is necessary to determine the characteristic parameters of the engine, motor, battery and simulation settings. In order to determine the actual operating conditions, the vehicle control strategy is proposed. Vehicle fuel economy, power and so on obtained from the results of the simulation meet the design goals, and it is able to complete the corresponding control strategy, you can achieve the engine, the motor starts and stops, brake energy recovery, and to ensure that the battery is kept within reasonable limits. Experimental results show that the modeling and simulation method is reasonable and effective.
