摘要
将多体系统动力学与模糊控制理论相结合对汽车稳定性控制(VDC)系统进行了研究。基于ADAMS/CAR建立整车多体动力学模型;研究汽车在不同行驶工况下,行驶稳定性参数的变化;利用Matlab/Simulink模糊控制工具箱建立稳定性模糊控制策略;通过ADAMS与Matlab间的数据接口将控制系统与整车动力学模型结合,对带有VDC系统的汽车进行典型行驶工况仿真试验。仿真结果表明:VDC系统通过差动制动模糊控制能够提高汽车的操纵稳定性。
The research of vehicle dynamic control（VDC） system based on multi-body system dynamics and fuzzy control theory was presented.A multi-body dynamics vehicle model was built by ADAMS/CAR,the change of vehicle kinematic parameters was researched under different conditions.A fuzzy controller was designed for the VDC system under Matlab environment.The contro1 system was combined with the vehicle dynamic model by data exchange interfaces between two kinds of software,the responses of vehicle with VDC system under various operating conditions were simulated.The result shows the VDC with the differential braking fuzzy control can improve vehicle handling stability.
