汽车主动前轮转向与防抱死制动系统集成控制研究-汽车主动前轮转向与防抱死制动系统集成控制研究.rar 以车辆动力学软件Carsim 和Matlab /Simulink 为平台, 分别建立了基于滑模变结构控制的主动前轮转向 和滑移率门限控制的防抱死制动系统 控制器模型, 并将2 种控制系统进行了集成, 建立了联合仿真模型。仿真结果表明, 在分离路面紧急制动工况下, 通过将AFS 与ABS 进行集成控制, 能够进一步提高ABS 的制动效能, 在保持车辆制动稳定性的同时缩短了制动距离。 A simulation model of the integrated dynamic control system of active front steering and anti- lock braking system is set up using carsim and matlab /simulink.Simulation has been done in regard to the AFS with the sliding- model control and the ABS with the slip rate threshold control.The simulation results indicate that the integrated control scheme can improve ABS performance when the vehicle is urgently braking on μ- split road,the integrated control system can keep the vehicle stable and shorten the braking distance simultaneously.
