【摘要】 在十五期间国家科技部通过“863”计划重大专项,加强对混合动力及纯电动等清洁、节能技术的研究,国内的主要汽车制造企业、大专院校及电机电池制造商都参与其中。在十一五期间,重大专项开始对混合动力产业化技术进行支持,同时2008年北京奥运清洁能源汽车示范运行及国家“十城千辆”示范计划有力的推进了混合动力及新能源汽车的产业化,但是国内厂家对混合动力技术的产品化还存在不同的理解。在高油价时代,如何有效利用混合动力技术的优势,开发适合市场的混合动力客车产品是国内客车生产企业面对的一个重要问题。在这样的背景下,本文结合国家“十二五”“863”课题——解放牌深度混合动力汽车产业化技术攻关对混合动力整车产品开发所涉及到的构型如何选择和关键总成参数如何进行设计的问题进行了比较全面的深入研究。论文的创新之处在于提出了面向产品工程化的混合动力客车设计方法,针对整车生产商的技术及工程能力制定了如何选择混合动力构型和如何匹配总成参数的方法,总结提出了基于系统效率的混合动力总成设计方法,在不同的城市循环工况下研究了基于系统效率对整车控制参数进行了优化,依据优化结果,改进了控制策略。论文全文包括以下四方面的内容:1、基于产品的混合动力构型选择方法;2、基于工况功率需求的关键总成功率匹配方法;3、基于正向仿真平台的整车关键控制策略开发及整车经济性验证;4、针对特定工况提出总成的高效区设计方法。基于上述的研究内容,本篇论文主要取得如下进展:论文首先通过对目前混合动力客车构型的分析验证了混合动力构型选择方法的有效性,并结合一汽深度混合动力客车开发,完成整车构型的选择及关键总成的参数确定。其次,应用正向仿真平台进行深度混合动力整车关键控制策略的开发,提出深混“插电化”进一步提升节油潜力的想法。并在混合动力技术进一步应对高油价提供有效方法。最后,论文通过对现有混合动力客车关键总成的改进设计,实现了基于特定工况的总成高效区的参数设计思想。试验结果显示,总成高效区的设计可以有效指导总成开发的方向,同时可以较大幅度地提高整车燃油经济性,深化整车控制技术。论文的研究是混合动力汽车等新能源汽车继续深入发展和大规模市场化的关键基础性工作。可以在工程约束条件下对不同类型、不同性能需求的混合动力汽车的构型选择设计,提供参数匹配原则和控制技术的指导,使得混合动力技术节油潜力得到进一步的深化。更多还原

【Abstract】 During the 10^th five years, The National Technical department of china had past Through the high Tech“863”plan, aiming at Enhancing The Research Investment on Hybrid Electric vehicle（HEV） and Pure Electric vehicle（PEV）, Major Automobile Manufacturing Factory and school all had Participated in it just like the Motor and Battery Suppliers. During the 11th five years, The plan had carried on the Industrial production of HEV. At the same time, The Demonstration movement of Olympic games Clean energy automobile and The demonstration plans of“ten city thousand cars”had accelerated the speed of Industrial production of HEV. But there had Different understanding of Industrial production of HEV in Domestic. In high oil price time, It is a big problem of how to utilize the Superiority of HEV when we Develop the products which suit the market.Under such background, The paper did quite comprehensive research on how to carry on the configuration and the design parameters of full hybrid electric vehicle named of liberation under the topic of 12^th five years“863”plan. The innovation of this paper is it elaborates the design methods on this HEV under product engineering restrain. In view of producer’s technology and project ability, this paper elaborates the methods on how to choose the configuration and how to match the design parameters. And it also summarizes the design method on how to match the power unit of this vehicle based on the system’s efficiency. Under different city cycles, it has carried out the optimization of control parameters based on the system’s efficiency. Based on the results of optimization, it improved the control strategy. The paper has the following four aspect content, which is1st, The method of how to choose the hybrid power unit based on production.2nd, The match method of how to design power system using power demand under the operating mode.3rd, The development of control strategy based on forward simulation platform and the confirmation of the vehicle’s fuel efficiency.4th, In view of the specific operating mode, the paper proposed the design method based on effective area.Based on the above research content, this paper mainly makes following progress, which isFirstly, the paper has confirmed the validity of the configuration choice method using the results of analysis. And with the development of the FAW full HEV, it completes the configuration choice and the parameter determination of the essential unit.Secondly, applies the forward simulation platform, it carries on the control strategy of the HEV. Furthermore, this paper proposed the idea of how to save gas and oil, which is using“insert and electrify”. And it also proposes the effective method on how to deal with the high oil price.Finally, under the improvement on power unit of HEV, this paper has realized the parameter concept using effective area based on the specific operating mode. The test results have demonstrated that the effective area’s design method may instruct the direction on unit development. At the same time, it can enhance the fuel efficiency and deepen the system’s control technology.The research of this paper is a foundational work which can push the HEV to a large-scale market. And it proposes the method on how to choose the configuration under the project constrains and different performance demand. And it also provides the parameter match principle and control strategy instruction, which can deepen the technology on how to save oil further.更多还原
