Identifying extreme situations of operating scenarios

One aspect of the present disclosure relates to a computer-implemented method for identifying extreme situations of a vehicle operating scenario, comprising: receiving one or more features for characterizing an operating state of a vehicle, extracting at least one trajectory map from a graphical database for the one or more features; modifying the at least one trajectory map, wherein a modified trajectory map is generated; reconstructing a first operation scene by the trajectory diagram; reconstructing a second operation scene by the modified trajectory diagram; and if the second operating scenario is evaluated as new and/or unknown based on predetermined criteria in comparison with the first operating scenario, identifying the second operating scenario as an extreme situation. 本公开的一个方面涉及一种用于标识运输工具运行场景的极端情况的以计算机实现的方法，包括：接收用于表征运输工具的运行状态的一个或多个特征，对于所述一个或多个特征从图形数据库中提取至少一个轨迹图；修改所述至少一个轨迹图，其中产生经过修改的轨迹图；由所述轨迹图重构第一运行场景；由所述经过修改的轨迹图重构第二运行场景；并且如果在与所述第一运行场景比较而言基于预定标准将所述第二运行场景评价为新的和/或未知的，则将所述第二运行场景标识为极端情况。
