摘　　要：针对汽车悬架复杂大系统的特点,在车辆动力学模型的基础上,研究半主动悬架系统对车身姿态的影响关系,运用模块化并联模糊控制和矩阵逆运算策略建立汽车整车半主动悬架控制系统;对不同的车身运动姿态采用不同的控制规则,设计整车车身姿态协调控制的模糊控制器。以某车型为例进行了仿真分析,结果表明,汽车整车半主动悬架模块化并联模糊控制器结构简单,并能有效抑制车身俯仰和侧倾运动,改善轮胎的接地性能,提高车辆的平顺性能。According to the characteristics of the full vehicle suspension large system, using the strategy of modularizes parallel fuzzy control and matrix pseudo inverse, the semi-active suspension control system was established. Based on the full vehicle dynamics model, the fuzzy controller based on full vehicle body poses coordinating control was designed. According to different vehicle body motion poses, the different control ruler was selected. Taking a light-duty vehicle as an example, the control model was simulated. The simulation result shows that the full vehicle suspensions modularize parallel fuzzy control strategy can restrain pitch and roll motion, and improve the tire ground- ing performance and ride comfort effectively.
