The embodiment of the invention relates to the technical field of automobiles, and particularly discloses a target vehicle cut-out detection method and system for adaptive cruise. According to the embodiment of the invention, by analyzing lane data, whether a front lane line is detected or not is judged, and whether the detection quality reaches the standard or not is judged; when the front lane line is detected and the detection quality reaches the standard, performing cut-out detection of the target vehicle based on the compensation lane line; and when the front lane line is not detected or the detection quality does not reach the standard, estimating a future motion path, synthesizing the distance data, the motion parameters and the driving data to carry out lane compensation analysis, determining a compensation lane line, and carrying out switching-out detection on the target vehicle. According to the method, the accuracy and efficiency of switching-out judgment of the front target vehicle can be improved, sudden braking and scratching accidents caused by inaccurate switching-out judgment are effectively avoided, the reliability of the ACC is guaranteed, meanwhile, the good performance is achieved on a curve, and the ACC can control the vehicle more comfortably and smoothly.

    本发明实施例涉及汽车技术领域,具体公开了一种自适应巡航的目标车辆切出检测方法及系统。本发明实施例通过对车道数据进行分析,判断是否检测到前方车道线,并判断检测质量是否达标;在检测到前方车道线,且检测质量达标时,并基于补偿车道线进行目标车辆的切出检测;在未检测到前方车道线,或检测质量不达标时,预估未来运动路径,综合距离数据、运动参数和驾驶数据进行车道补偿分析,确定补偿车道线,进行目标车辆的切出检测。能够提高对前方目标车辆切出判断的准确性与效率,有效避免由于切出判断不准确导致的急刹车与剐蹭事故,保障ACC的可靠性,同时在弯道时也有比较好的表现,能让ACC对车辆的控制更加舒适、流畅。
