摘要
车辆转弯制动是一种常见的危险工况。首先基于ADAMS建立了整车动力学模型,并在不施加任何控制时针对转弯制动工况进行仿真分析,结果出现侧滑、甩尾现象,车辆极不稳定。因此在MATLAB/Simlink中设计了基于滑移率的ABS模糊控制系统,结合ADAMS中的整车动力学模型,建立了ADAMS和MATLAB/Simlink联合仿真模型,并进行了转弯制动工况下的仿真。结果表明,ABS控制能极大地改善车辆在转弯制动下的稳定性。
Vehicle turning braking is a dangerous working condition. Vehicle dynamics model was established in ADAMS first, and simulation under turning braking without control was done, The resuits show that the vehicle obvious instability and swerve phenomenon was occurred. So a fuzzy ABS control system based on the slip rate was established under fuzzy control method in MATLAB/Sim link, combined with established vehicle dynamics model in ADAMS, co--simulation model was estab- lished in ADAMS and MATLAB/Simlink for turning braking. The results show that vehicle stability is greatly enhanced with fuzzy ABS control system.
