混合动力电动汽车动力系统选型策略分析

Tactics Study on Selecting Power Train Type of Hybrid Electric Vehicle

目前，混合动力电动汽车（ＨＥＶ）在世界范围内成为新型车辆开发的热点。在ＨＥＶ的开发中，动力系统选型处于重要的地位。ＨＥＶ的动力系统基本可分为串联式、并联式和混联式３种。在选型中，需要考虑使用条件、性能要求、技术条件、开放性和成本、使用维护费用等因素。针对我国国情，我国对ＨＥＶ开发，应优先选择结构简单、适用于普通城市交通的串联式结构和城市间交通的并联式结构，以公共汽车作为重点开发对象。

The hybrid electric vehicle(HEV) is now becoming a careful attention point in new vehicle developing in the world wide. In HEV developing, selecting power train type is in an important position. The power train system in HEV is basically devided into three types: serial, parallel and combined type. For type selection, some facrors such as usage conditions, performance vequirements, technical specifications, open ability, cost, service and maintenance expenses, etc must be considered. In view of our country's situations, a simple structure and a serial power train system which is suitable to popular and public city traffic and a parallel power train ayatem which is suitable to intercity traffic are given priority of consideration, and take the public buses as a major developing project.
