摘　　要：针对汽车多工况行驶对操纵稳定性和平顺性的综合要求,提出了一种基于混合模糊控制的半主动悬架整车控制策略。在Simulink-Stateflow中设计了混合控制器,以某车多体动力学模型为例进行了随机路面和蛇形道路上不同车速下的SIMPACK/Matlab联合仿真,最后基于dSPACE和试验车辆的硬件仿真平台,进行悬架系统实车测试。结果表明,所提出的混合模糊控制是可行的,能较好地改善车辆行驶平顺性和操纵稳定性。According to the requirements on both handling stability and ride comfort performance of vehicle in multi-condition driving,a semi-active suspension control strategy based on hybrid fuzzy control is proposed. A hybrid controller is designed with Simulink /Stateflow,and with the multi-body dynamics model for a car as example,a SIMPACK /Matlab co-simulation on both random input running test and pylon course slalom test at different speeds is conducted. Finally based on dSPACE and the hardware simulation platform of tested vehicle,a real vehicle suspension system test is performed. The results indicate that the hybrid fuzzy control strategy proposed is feasible and can well improve the ride comfort and handling stability of vehicle.
