The invention provides a brake intensity fuzzy recognition method considering a brake intention. The method comprises the following steps: firstly, acquiring brake pedal data by an experiment, classifying the brake pedal data by taking brake strength as a standard according to brake intentions, and performing parameter offline identification on an HMM model by using a method of identifying while verifying to obtain HMM model parameters of each brake intention at each output moment; secondly, according to a brake pedal displacement time sequence obtained in real time, recognizing the brake intention online through a time-sharing output, reasonable prediction and comprehensive judgment method, and furthering using brake pedal displacement and brake pedal force as input of a first-layer fuzzycontroller to output a brake intention coefficient; and finally, using the brake intention coefficient and the brake pedal displacement change rate as input and output brake intensity of a second-layer fuzzy controller, and obtaining estimated brake intensity. The method can accurately reflect the braking intention of a driver in real time and adapt to the changeable braking intention of the driver.
本发明提供了一种考虑制动意图的制动强度模糊识别方法,首先由实验获取制动踏板数据并以制动强度为标准按制动意图进行分类,使用“边识别,边验证”的方法对HMM模型进行参数离线识别,获得各输出时刻下各制动意图的HMM模型参数;然后根据实时获取的制动踏板位移时间序列,采用“分时输出,合理预测,综合判断”的方法对制动意图在线识别,进一步以制动踏板位移和制动踏板力作为第一层模糊控制器的输入,输出制动意图系数;最后以制动意图系数和制动踏板位移变化速率作为第二层模糊控制器的输入,输出制动强度,获得估测的制动强度。本发明能准确、实时地反映驾驶员的制动意图并适应驾驶员多变的制动意图。
