The embodiment of the invention provides a self-adaptive cruise control method and system and a vehicle, and the method comprises the steps: determining a workshop time interval value and a collision risk degree value of two workshops according to a driving state; according to the two values, determining a target fuzzy subset corresponding to the workshop time interval value in the workshop time interval fuzzy set and a target fuzzy subset corresponding to the risk degree value in the risk degree fuzzy set; according to a fuzzy rule, determining a first fuzzy subset corresponding to the target fuzzy subset in a first fuzzy set of a first correction variable, the first correction variable being a correction variable corresponding to the first index weight; performing defuzzification on the first fuzzy subset to obtain a corresponding target value; correcting the first index weight through the target value to obtain a first corrected index weight; and performing adaptive cruise control based on the first correction index weight. The adaptive cruise control method aims at improving the adaptability of adaptive cruise control so as to improve the comfort and reliability of driving.
本申请实施例提供一种自适应巡航控制方法、系统及车辆,方法包括:根据行驶状态,确定两车间的车间时距取值和碰撞的风险程度取值;根据该两个取值,确定车间时距模糊集中对应车间时距取值的目标模糊子集和风险程度模糊集中对应风险程度取值的目标模糊子集;根据模糊规则,确定第一修正变量的第一模糊集中对应目标模糊子集的第一模糊子集,第一修正变量为与第一指标权重对应的修正变量;通过对第一模糊子集进行解模糊化,获得对应的目标取值;通过目标取值对第一指标权重进行修正,获得第一修正指标权重;基于第一修正指标权重进行自适应巡航控制。旨在提升自适应巡航控制的适应性,以提升驾驶的舒适性和可靠性。
