【摘要】 近年来,节能与环保已成为世界各国关注的重大问题,汽车是化石能源消耗和污染大气环境的大户,世界各国的汽车行业研究者都在利用各种新技术、新方法来解决汽车的节能环保问题。在此背景下,混合动力电动汽车(HEV)由于其良好的经济性能和较低的排放性能以及能更好利用传统内燃机汽车现有基础设施等原因,被认为是本世纪解决汽车面临的石油能源危机和环境污染问题的有效方案之一。在计算机技术发达的今天,建立数学模型并利用计算机对HEV实际情况进行仿真研究分析,不仅可以深入了解各因素对HEV整车性能的具体影响,灵活地调整HEV设计方案,优化动力总成系统设计参数,而且可以减少开发成本,缩短开发周期,从而适应当今世界激烈的市场竞争。以往的车辆仿真,其重心主要集中在动力总成方面。而车辆在实际运行中,辅助能量附件系统(例如,空调系统、动力转向系统、制动系统、发动机冷却系统等)所消耗的能量占整车油耗的9-15%左右,这部分的能量仿真目前被很多研究者所忽视。本文结合“十一五”期间国家高技术研究与发展计划(“863”计划)“电动汽车”重大专项的研究课题“电动汽车控制算法与基础技术研究”的研究工作,提出了考虑附件系统能耗模型的HEV综合能量流模型,并在此模型基础上本文完成了附件系统工作特性分析、HEV参数对整车性能影响、HEV参数优化设计和综合能量流模型硬件在环仿真等方面的研究工作,可以为HEV的整车设计开发提供必要的理论指导。更多还原

【Abstract】 In recent years, energy-saving and environmental protection has become a major issue of all countries in the world. Vehicles take tremendous responsibility for fossil energy consumption and pollution of atmospheric environment. New methods and technologies are studied by many automotive researchers to solve the energy-saving and environmental protection problem for vehicles. Under this background, hybrid electric vehicles (HEV) , due to its good economic performance , low emissions performance, better use of traditional ICE vehicle’s existing infrastructure, and other factors, are considered one of the eff(?)ctive solutions.In the modern development of computer technology, the measure of establishing mathematical models and using computers to simulate the actual situation in HEV research, not only can help people to study the various factors on the specific impact of vehicle performance, but also can adjust HEV subsystem design and optimize parameters. Through this method, researchers can reduce development costs and short the product development cycle, meet the current needs of the world the fierce market competition.In the previous vehicle simulation, its focus mainly concentrated in the powertrain area. But in the actual operation of vehicles, auxiliary system (for example, air-conditioning systems, power steering system, brake system, engine cooling system, etc.) consume 9-15% of vehicle fuel consumption. This part of the energy consumption is ignored by previous simulation.Supported by the major project "Research on Control Algorithm and Basis Technology for Electric Vehicles" under "High-Tech R&D Program of China", the HEV integrated energy flow model, which calculates Vehicle auxiliary system energy consumption, has been proposed. On this basis, the study of auxiliary system analysis, HEV vehicle and control strategy parameters performance and optimization and hardware in-the-loop simulation have been carried our. I think this study can provide the necessary theoretical supervise for HEV design and research.更多还原
