汽车混合动力控制策略概述VIP专享

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进展。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，故将本课题讨论内容适当缩小。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，ADVISORABSTRACTForced the two pressure of Energy crisis and environmental protection ， Hybrid electric vehicles are actively developed in the world. Hybrid electric vehicle (HEV) can be regarded as the period of change from a traditional fuel cell cars to pure electric， and it is a transitional model that combined with electric motors and internal combustion engine. Although it does not achieve zero emissions，before the energy storage components in electric cars - Battery had no fundamental breakthrough ， What power ， economy and emission targets can be achieved is one of the increasingly acute and good way through mitigation of environmental pollution and automobile demand and conflict between the oil shortage.Control strategy is the core operation of hybrid vehicles. Hybrid electric vehicle is a standards of environmental protection mode vehicles，the energy unit is usually combinde with the engine， batteries and motor. According to...
