摘　　要：为协调车辆操纵稳定性和行驶平顺性,在分析半主动悬架和电动助力转向工作原理的基础上,研制出以嵌入式系统为平台的车辆底盘系统集成控制器。硬件上对悬架可调阻尼减振器的步进电动机和转向系统的直流电动机进行控制设计;软件上运用模糊控制和PID控制算法,在CodeWarrior集成开发环境下结合超级终端对软硬件进行联调。试验结果表明,控制器运行可靠,电动机控制正确、效果明显,集成控制下车辆的操纵稳定性和平顺性得到改善。In order to harmonize the performance of vehicle handling stability and riding comfort, an integrated controller of vehicle chassis system was designed based on embedded system after analyzing the principles of semi-active suspension（SAS） and electric power steering （EPS）. Stepper motor of suspension adjustable damper and DC motor of EPS were controlled respectively by hardware. Fuzzy and PID arithmetic were applied in software. United adjustment to hardware was done with HyperTerminal under the condition of CodeWarrior integrated development. Experiment results proved the controller and motors were running reliably, handling stability and riding comfortably when integrated condition were being improved.
