摘　　要：在建立的包含电动助力转向系统的转向运动模型、俯仰运动模型和侧倾运动模型汽车整车模型基础上,选用车身横摆角速度、横向运动速度等参数评价车辆操纵稳定性。运用95百分位四次幂和力作为动载荷道路破坏的评价指标,设计了自适应模糊控制的汽车主动悬架与电动助力转向系统集成控制器,并分析了不同路面和速度对理论道路破坏系数的影响。计算结果表明,该自适应模糊集成控制策略,与被动悬架与转向系统比较,既保证了车辆操纵轻便性,又明显提高了整车稳定性,同时集成控制的车辆具有良好的道路友好性,延长了道路的使用寿命。The full-car model contains the electric power steering model, bounce and pitch model, bounce and roll model were established, yaw rate and lateral speed were fourth power aggregate force is used as the criterion for road utilized to evaluate vehicle stability, and 95 percentage damage. The integrated controller of automotive active suspension system and electrical power steering system based self-adaptive fuzzy logic were designed. The calculated results showe that the handiness could be improved by presented control scheme, and the performance of vehicle stability is enhanced. And at the same time the vehicle has excellent road friendliness, the life of the road is extended.
