混合动力控制策略I摘要迫于能源危机和环境保护两大压力,混合动力电动汽车在全世界范围内得到大力发展。混合动力电动汽车(HEV)可以视为是传统燃油汽车向纯电池电动汽车的转变时期,由电动机和内燃机结合使用的一种过渡车型。它虽然没有实现零排放,但在电动汽车的储能部件—电池没有根本性突破以前,其所能达到的动力性、经济性和排放指标是缓解汽车需求与环境污染及石油短缺矛盾日益尖锐的理想途径之一。控制策略是混合动力汽车运行的核心。混合电动汽车是一种准环保型的车辆,其能源装置通常由发动机,电池和电机组合而成。它能根据不同的行驶工况,实现单能源或多能源联合驱动方式,达到减少油耗和排放的最终目的。因此,在整车配置确定的前提下,如何实现多种动力源的协调工作,是混合电动汽车能源管理核心之一。本课题由于内容十分宽广,再加上本人本科阶段学习理论水平有限,故将本课题研究内容适当缩小。故本课题通过现今主流的控制策略分析,对同一车型在ADVISOR软件内置不同控制策略的比较仿真,寻找城市路况下比较可行的控制策略。关键词;汽车混合动力,控制策略,仿真,ADVISOR混合动力控制策略IIABSTRACTForcedthetwopressureofEnergycrisisandenvironmentalprotection,Hybridelectricvehiclesareactivelydevelopedintheworld.Hybridelectricvehicle(HEV)canberegardedastheperiodofchangefromatraditionalfuelcellcarstopureelectric,anditisatransitionalmodelthatcombinedwithelectricmotorsandinternalcombustionengine.Althoughitdoesnotachievezeroemissions,beforetheenergystoragecomponentsinelectriccars-Batteryhadnofundamentalbreakthrough,Whatpower,economyandemissiontargetscanbeachievedisoneoftheincreasinglyacuteandgoodwaythroughmitigationofenvironmentalpollutionandautomobiledemandandconflictbetweentheoilshortage.Controlstrategyisthecoreoperationofhybridvehicles.Hybridelectricvehicleisastandardsofenvironmentalprotectionmodevehicles,theenergyunitisusuallycombindewiththeengine,batteriesandmotor.Accordingtodifferentdrivingconditions,Itcanrealizesingle-energyorenergyco-drivenapproachtoreducingfuelconsumptionandemissionsoftheultimategoal.Therefore,beforedeterminingthevehicleconfigurations,Howtoachievethecoordinationofavarietyofpowersources,hybridelectricvehicleenergymanagementisoneofthecore.Asthecontentofthistopicisverybroad,togetherwithmyundergraduateleveloflearningtheoryislimited,thecontentsofthispaperoftheappropriatereduced.Therefore,thispaperbuildsthesamesimulationmodeltogetcomparisonofdifferentcontrolstrategiesbyADVISOR,basedonthecurrentpopularcontrolstrategy.Tofindcontrolstrategyintheurbanoperationcondition.Keywords:hybridcontrolstrategy,simulation,ADVISOR混合动力控制策略III目录1绪论-------------------------------------------------------------------------------------------------------------------11.1混合动力汽车研究背景-----------------------------------------------------------------------------------11.2国内外混合动力发展状况-------------------------------------------------------------------------------21.3混合动力汽车控制策略的研究现状------------------------------------------------------------------21.4本文主要研究内容------------------------------------------------------------------------------42混合动力系统分类与选择--------------------------------------------------------------------------------52.1混合动力汽车的类型及特点---------------------------------------------------------------------------52.1.1串联式混合动力结构与性能特点-----------------------------------------------------------52.1.2并联式混合动力结构与性能特点-----------------------------------------------------------52.1.3混联式混合动力结构与性能特点-----------------------------------------------------------62.2混合动力汽车混合度-----------------------------------------------------------------------------------82.3电池的能量存储及电池管理系统-------------------------------------------------------------------83混合动力汽车控制策略研究-------------------------------------------------------------------------103.1混合动力汽车控制策略的设计要求--------------------------------------------------------------103.2混合动力汽车控制策略-------------------------------------------------------------------------------103.2.1串联型混合动力汽车的控制策略---------------------------------------------------------103.2.2并联型混合动力汽车的控制策略---------------------------------------------------------113.2.3混联型混合动力汽车的控制策略---------------------------------------------------------134基于ADVISOR的仿真及分析--------------------------------------------------------------------------154.1ADVISOR仿真软件简介-------------------------------------------------------------------------------154.2混合动力汽车仿真方法-------------------------------------------------------------------------------164.2.1前向仿真法----------------------------------------------------------------------------------------164.2.2后向仿真法---------------------------------------------------------------------------------------164.3ADVISOR中混合动力汽车主要部件的建模实现---------------------------------------------174.3.1仿真模型选择-------------------------------------------------------------------------------------174.3.2仿真模型主要部件选择-----------------------------------------------------------------------174.4仿真结果对比---------------------------------------------------------------------------------------------194.4.1Prius车辆和Conventional车辆动力性对比-------------------------------------194.4.2Prius车辆和Conventional车辆排放性对比-------------------------------------214.4.3Prius车辆和Conventional车辆燃油经济性对比------------------------------225ADVISOR中控制策略对比仿真------------------------------------------------------------------------245.1并联控制策略------------------------------------------------------------------------------------------24混合动力控制策略IV5.2电辅助控制---------------------------------------------------------------------------------------------245.3模糊控制策略------------------------------------------------------------------------------------------
