The present invention relates to a method of classifying driving behavior of a traffic participant in the surroundings of a host vehicle, comprising receiving trajectory data of a driving trajectory of a traffic participant in the surroundings of the host vehicle, comprising position information of the driving trajectory; calculating the hidden space representation of the driving track in the hidden space, wherein the hidden space representation of the driving track is given by the dimension reduction representation of the track data; calculating the distance between the hidden space representation of the driving track and the hidden space representation of the normal track in the hidden space, wherein the normal track is classified as the driving track based on the normal driving behavior; and classifying the driving behavior as a normal driving behavior if the distance between the hidden space representation of the driving trajectory and the hidden space representation of the normal trajectory in the hidden space is lower than a boundary value; if the distance between the hidden space representation of the driving track and the hidden space representation of the normal track in the hidden space exceeds a boundary value, classifying the driving behavior as an abnormal driving behavior; and outputting the classification information. The invention also relates to a method of controlling a vehicle.
本发明涉及对本车辆周围环境中的交通参与者的行驶行为分类的方法,包括接收本车辆周围环境中的交通参与者的行驶轨迹的轨迹数据,其包括行驶轨迹的位置信息;求取行驶轨迹在隐空间中的隐空间表示,行驶轨迹的隐空间表示由轨迹数据的降维表示给出;求取行驶轨迹的隐空间表示与正常轨迹在隐空间中的隐空间表示的距离,正常轨迹被分类为基于正常行驶行为的行驶轨迹;和如果行驶轨迹的隐空间表示与正常轨迹在隐空间中的隐空间表示的距离低于边界值,则将行驶行为分类为正常行驶行为;如果行驶轨迹的隐空间表示与正常轨迹在隐空间中的隐空间表示的距离超过边界值,则将行驶行为分类为异常行驶行为;和输出分类信息。本发明还涉及控制车辆的方法。
