摘　　要：为避免汽车在对开路面制动时出现跑偏或侧滑等危险工况,提出了一种利用横摆力矩方法控制汽车制动稳定性的控制模式,设计了模糊控制器,按照所确定的控制策略进行了仿真。仿真与试验结果对比表明,利用所提出的汽车制动稳定性横摆力矩模糊控制方法,能减少汽车在路面附着系数相差较大的对开路面制动时的侧滑和激转,并使汽车在制动偏驶后能快速恢复到预期行驶车道,避免了汽车制动力不平衡引起的危险工况。In order to avoid the dangerous situations of wandering or skidding when automobile braking on bisectional roads, a control mode by yaw moment to control automobile braking stability was proposed, and the fuzzy controller was designed. The simulation results by this control strategy were compared with experiment ones. The results show that this method of yaw moment fuzzy control can reduce the risks of skidding and wandering when automobile braking on bisectional roads with large difference between inside and outside road adhesion coefficients, restore automobile to expected lane after wandering, avoid the dangerous working condition. 2 tabs, 8 figs, 6 refs.
