摘要
混合动力汽车采用内燃机和电动机作为动力源，其燃油消耗和排放都比传统汽车低，并能满足日益严格的汽车尾气排放标准。从整车效率、动力性能、续驶里程和城市运行工况等多方面综合考虑，混联式混合动力电动汽车为首选方案。混合动力汽车动力总成参数匹配技术是混合动力汽车的核心技术之一，而一个良好的控制策略则是保证低油耗、低排放的关键。本文在如下几方面做了详细的研究工作：
1、详细地论述混合动力系统的基本结构、工作原理及优缺点；对混合动力电动汽车的动力系统的设计进行分析，并选择混合动力系统的类型；
2、在确定功率需求的基础上确定混和动力电动汽车动力总成的初步匹配方案，满足排放标准同时具有较好动力性和燃油经济性，并初步验证研究参数匹配的合理性；
3、对混联混合动力汽车动力及传动系统各主要部件的性能进行选择动力装置类型和参数设计；参考混联式混合动力汽车典型例子——丰田pruis的驱动系统，针对伊兰特1.6进行了混合动力系统设计。
4、在完成混合动力系统的基础上，通过对行车工作模式的分析和参考串联混合动力系统与并联混合动力系统的控制策略，设计其控制系统；

Abstract
The hybrid electric vehicle satisfied the increasingly strict criterion of vehicle exhaust emission with its better performance on high fuel economy and low emission than the Conventional Vehicle,which is strongly depend on the cooperation of internal.combustion and electromotor.According to the car efficiency power performance,sail mileage and city routine etc,parallel-series HEV is finally adopted.The HEV parameter design is one of the core technologies and a nice control strategy is the key to guarantee the low emission and fuel consumption.This thesis introduces the developments as follows:
1.Discusses in detail the hybrid electric system for basic structure,and its advantages and disadvantages; the hybrid electric vehicle design of the dynamical system for analysis, and select the type of hybrid electric system;
2.In determining the need to determine on the basis of a mixture containing electric vehicle powertrain of match, at the same time meet the emission standards for determining glutamateis power performance and fuel economy, and preliminary validation of parameters match parameters reasonability;
3.On hybrid HEV and transmission system performance across all the major parts of the choices power unit type and parameter design; refer to the parallel hybrid electric vehicle: a typical example of Toyota pruis drive system, carried out for elantra 1.6 hybrid electric system design;
4.Upon completion of the hybrid system, through the operation mode of analysis, and reference series hybrid system and a parallel hybrid system control strategy, design its control system.
Key Word: hybrid cars;PSHEV;parameter matching；control strategy
