用于混合电动车的直线发动机控制系统

摘要

研制了一种用于混合电动车的直线发动机／发电机动力系统。该系统的直线发动机样机是基于一款二冲程发动机原型机，经过机械结构和电控化改造后搭建完成的。根据初期的试验目标，设计了直线发动机试验台架测控系统，包括瞬态数据采集系统以及基于LabVIEW虚拟仪器的软件控制界面。利用基于Infineon公司的XC167CI芯片开发的控制器，进行软硬件的开发，实现了直线发动机的起动控制。验证了该发动机样机的可行性，对该发动机起动过程的运动特性做了探索性试验。该样机已正常运转。%A linear engine-alternator combination power system was developed for Hybrid Electric Vehicle （HEV） application. The linear engine prototype was accomplished based on a two-stroke original engine using modification of a mechanical system and an electronical control system. According to the experimental objective at earlier stage, a measurement and control system was developed including a transient data acquisition system and the software based on LabVIEW. Starting process control of the engine was realized after the design of software and hardware based on Infineon processing chip XC167C1. The feasibility of the prototype was verified with some exploratory experiments made to study the linear engine movement characteristics. The results show that the developed prototype can operate normally.
