摘　　要：以飞思卡尔MC9S08GT32A单片机为控制核心,设计了一种通过检测车身高度对空气弹簧进行充排气,进而改变弹簧刚度的客车电控空气悬架系统(ECAS)。重点阐述了控制悬架系统的硬件设计,并对软件设计进行了总体介绍。最后通过进行实车道路试验,并与钢板弹簧的车辆所测出的数据进行比较,得出电控悬架系统的主要性能改善程度。We designed the electric air suspension system（ECAS）,using Freescale MC9S08GT32A microcomputer as the controlling core.This ECAS can fill and exhaust the air springs by detecting the height of body,and then the spring stiffness of the passenger car is changed.This paper emphasized the hardware design of ECAS,meanwhile,conducted a general overview of the software design.At last,through the real vehicle test,we obtained the improving level of ECAS in main performances,comparing with the data measured from the passenger car with leaf springs.
