摘　　要：在ADAMS/Car下,建立了前后悬架都装有主动横向稳定杆的95自由度虚拟整车模型.采用模糊自适应PID控制策略,在Matlab/Simulink环境中对车辆抗侧倾性能进行了联合仿真,实现了PID控制过程中参数的在线整定.仿真结果表明,模糊自适应PID控制具有较强的自适应和抗干扰能力,有效地减小了车身侧倾角,在保证乘坐舒适性的同时提高了车辆的行驶稳定性.A virtual car model is built by using ADAMS/Car. The model is simplied with 95 DOFs equipped with active antiroll bars in front and rear suspension. A fuzzy running PID controller using roll angle input source is applied in the active roll control. It is co - simulated under the Matlab/ Simulink software environment and realizes the online coordination. The simulation results show that this controller has the ability of self - adjusting and decreases the chassis roll angle effectively. The vehicle riding comfort is ensured and the vehicle directional stability is improved.
