摘　　要：提出了车辆防抱制动系统与主动悬架联合控制的策略 :当车辆制动时 ,主动悬架控制系统不再以乘坐舒适性为主要控制目标 ,而是作为调节轮胎法向反力变化的工具 ,使得轮胎法向反力在车轮滑移率达到最优时也达到最大值 ,从而获得最大地面制动力。结合 7自由度非线性车辆模型 ,考虑轮胎动态特性的影响 ,利用基于滑模变结构控制理论联合控制策略进行了车辆制动模拟试验。试验结果表明 ,车辆采用防抱制动系统与主动悬架联合控制 ,在保证车辆制动稳定性的同时充分利用路面提供的最大附着系数 ,获取最大地面制动力 。This paper made an investigation on the integrated control scheme of vehicle anti lock braking system (ABS) and active suspension. The objective of this investigation is to obtain the maximum braking force on the road and to minimize the stopping distance and meanwhile maintain vehicle directional stability. The controller was designed by using the sliding model control theory and was implemented under the Matlab/Simulink software environment. A 7DOFvehicle model was used to consider the influences of the non linearity of tire and suspension. The simulation tests were carried out in various conditions. The action of the ABS combined with active suspension and the effects of applied suspension force on braking performances were examined. The simulation results showed that for a particular vehicle there existed an optimal application of the suspension force. Compared with an ABS system without combining active suspension, the proposed control scheme can improve braking performance significantly.
