The invention discloses an EMB vehicle ABS fuzzy control method based on the optimal slip rate. The EMB vehicle ABS fuzzy control method comprises the following steps that 1, signals are collected; step 2, fuzzy quantization; step 3, fuzzy reasoning; and 4, performing fuzzy judgment. The slip rate, the slip rate error and the change rate of the slip rate error in the automobile braking process are obtained in real time by collecting signals, and the slip rate error and the change rate of the slip rate error serve as input quantities of fuzzy control; performing fuzzy quantization, fuzzy reasoning and fuzzy judgment on the input quantity to obtain an output quantity of fuzzy control; and finally, the control system adjusts the brake pressure according to the output quantity of the fuzzy control, so that the slip rate acquired in real time is at the position of the optimal slip rate. The braking distance of the vehicle can be shortened, and the braking stability is improved.
本发明公开了一种基于最佳滑移率的EMB车辆ABS模糊控制方法,包括以下步骤:步骤1,采集信号;步骤2,模糊量化;步骤3,模糊推理;步骤4,模糊判决。通过采集信号实时获取汽车制动过程中的滑移率、滑移率误差、滑移率误差的变化率,将滑移率误差及滑移率误差的变化率作为模糊控制的输入量;然后对输入量进行模糊量化、模糊推理、模糊判决进而获得模糊控制的输出量;最后控制系统以该模糊控制的输出量调节制动压力使实时采集的滑移率处于最佳滑移率的位置。本发明能够缩短车辆的制动距离、提高制动的稳定性。
