The invention provides a threat assessment method for automatic lane changing assistance, which comprises the following steps: when lane changing is needed, judging whether the longitudinal distance between a vehicle and a target vehicle in front of or/and behind the vehicle on a target lane meets the requirement or not in the lane changing process; whether the safety distance limiting time between the vehicle and a target vehicle in front of or/and behind the vehicle on the target lane meets the requirement or not in the lane changing process is judged; if the judgment result of any item is no, threatening exists in the lane changing process, and if all the judgment results are yes, threatening does not exist in the lane changing process. Therefore, the problems that existing lane changing threat judgment and consideration conditions are incomplete, and lane changing safety and experience are affected are solved.

    本发明提供一种用于自动变道辅助的威胁评估方法,其包括:在需要变道时,需要判断本车与目标车道上的本车前方或/和后方的目标车之间的纵向距离在变道过程中是否满足要求,以及判断本车与目标车道上的本车前方或/和后方的目标车之间的安全限距时间在变道过程中是否满足要求;在任意一项的判断结果为否时,则认为变道过程中存在威胁,在所有的判断结果均为是,则认为变道过程中不存在威胁。这样解决了现有变道威胁判断考虑情况不全,影响换道安全与体验等问题。
