摘　　要：半主动悬架作为底盘的减震保稳部件对车辆的乘坐舒适性极为重要,电动助力转向提供转向助力与车辆的操纵稳定性密切相关,为提高车辆的操纵稳定性和行驶平顺性,笔者对半主动悬架和电动助力转向进行了集成控制研究。运用模糊和PID策略分别对悬架和转向进行控制,利用机械液压仿真软件AMESim联合MATLAB/Simulink进行了集成控制仿真,研制出基于嵌入式系统的半主动悬架和电动助力转向集成控制器并进行了实车路试。仿真和试验结果表明:半主动悬架和电动助力转向集成控制提高了车辆的操纵稳定性和行驶平顺性。As the damping part of a chassis, a semi-active suspension （SAS） is very/mportant to vehicle riding comfort. An electric power steering （EPS） system is closely related to the handling stability by providing powerassisted steering. In order to improve the vehicle handling stability and riding comfort, integrated control based on SAS and EPS is studied in this paper. Fuzzy method and PID arithmetic are adopted to control SAS and EPS respectively. Co-simulation of AMESim and MATLAB/Simulink is applied to the integrated control model. An integrated controller based on embedded system is developed, and road test is conducted. Results of simulation and road test indicate that the vehicle＇s handling stability and ride safety and comfort are remarkably improved.
