The invention relates to a method and a warning device for issuing a warning relating to an obstacle (36) to a following vehicle (42) on a defined road section (10), a plurality of host vehicle trajectories (14) of a host vehicle (12) moving on the road segment (10) are captured within a first timestamp (t1, t2) and thereby a first group of trajectories (30) is formed and stored together with a first timestamp (T1). Similarly, in a second time interval [t3; t4) forming a second population of trajectories (38) for the host vehicle (12) moving on the road segment (10) within a second time interval [t3; t4) relative to the first time interval [t1; t1, t2) is offset in time. The second population of trajectories (38) is also stored together with a second timestamp (T2), and then a difference between the first population of trajectories (30) and the second population of trajectories (38) and an associated difference amplitude (| [Delta] x |) are formed. If the difference amplitude (| [delta] x |) is greater than a predetermined threshold value (xs), the presence of an obstacle (36) on the road segment (10) is identified, and then a warning signal (40) is output to the following vehicle (42). The invention also relates to a corresponding warning device designed to carry out the method.
本发明涉及一种用于向定义的道路段(10)上的跟随车辆(42)发出有关障碍物(36)的警告的方法和警告设备,其中,在第一时间区间[t1;t2]内捕获在该道路段(10)上移动的本车辆(12)的多个本车轨迹(14),并且由此形成第一群体轨迹(30),并将该第一群体轨迹与第一时间戳(T1)一起存储。类似地,根据在第二时间区间[t3;t4]内在该道路段(10)上移动的本车辆(12)的本车轨迹(14)形成第二群体轨迹(38),该第二时间区间[t3;t4]相对于该第一时间区间[t1;t2]在时间上有所偏移。也将该第二群体轨迹(38)与第二时间戳(T2)一起存储,然后,形成第一群体轨迹(30)与第二群体轨迹(38)之间的差值和相关联的差值幅度(│Δx│)。如果该差值幅度(│Δx│)大于预定阈值(xs),则识别出障碍物(36)存在于该道路段(10)上,然后向跟随车辆(42)输出警告信号(40)。本发明还涉及一种被设计成执行该方法的对应警告设备。
