The invention relates to a self-adaptive cruise control method. The self-adaptive cruise control method comprises the following steps: acquiring the vehicle speeds of at least two front vehicles located on the same lane as the vehicle and the vehicle speed of the vehicle; the time for keeping the vehicle speed of the two front vehicles in a stable state is calculated, whether the time for keeping the vehicle speed of the two front vehicles in the stable state is larger than or equal to first set time or not is judged, and the vehicle speed keeping in the stable state means that the vehicle speed is basically kept at a certain vehicle speed, and the vehicle speed deviation value is smaller than a first threshold value; and a correction step of correcting a vehicle distance preset by an adaptive cruise system of the vehicle at a certain time interval into a corrected vehicle distance under the condition that the time for keeping the vehicle speeds of the two preceding vehicles in a stable state is greater than or equal to a first set time, so that the vehicle distance between the vehicle and the adjacent preceding vehicle can be controlled into the corrected vehicle distance. The invention further relates to an adaptive cruise control system.

    本发明涉及一种自适应巡航控制方法,包括:采集与车辆位于同车道的至少两辆前车的车速以及车辆的车速的采集步骤;计算两辆前车的车速保持稳定状态的时间,并判断两辆前车的车速保持稳定状态的时间是否大于等于第一设定时间的判断步骤,其中,车速保持稳定状态是指车速基本维持于某一车速,车速偏差值小于第一阈值;以及在两辆前车的车速保持稳定状态的时间大于等于第一设定时间的情况下,以一定时间间隔对车辆的自适应巡航系统预设的车距进行修正,将其修正为修正车距,从而能将车辆与相邻前车的车距控制为修正车距的修正步骤。本发明还涉及一种自适应巡航控制系统。
