摘要
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(AFS)和滑移率门限控制的防抱死制动系统(ABS)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 （AFS）and anti-lock braking system （ABS）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.
