摘要
针对传统的刹车控制方法在一些复杂路段进行刹车控制的时候,存在刹车距离大,控制时间长的缺陷。为此提出了一种基于模糊控制理论的汽车智能刹车控制方法。通过建立汽车整车动力模型,通过深入研究刹车控制原理,结合模糊控制理论完成刹车的智能控制。结果表明模糊控制器可以使得车辆的实时滑移率快速到达并保持在期望滑移率附近,从而使车辆获得最大的地面制动力以提高刹车性能,并在缩短制动距离同时保持方向的可操控性,相比于传统的控制器取得了更好的控制效果。
In traditional brake control methods in some complex sections for brake control,exist brake distance,control the time long defects.Therefore put forward based on fuzzy control theory of the intelligent braking control method.Through the establishment of automotive dynamic model,through the thorough research the brake control theory,combined with the fuzzy control theory to complete the brakes on intelligent control.The results show that the fuzzy controller can make the real-time vehicles the slip rate fast access to and keep expectations in the slip rate near,thus make the vehicle for maximum ground braking force in order to improve the brake performance,and shorten the braking distance and keep in the direction can be manipulative,than the traditional controller made better control effect.
