The invention provides a driving behavior evaluation method and device for an automatic driving vehicle, and belongs to the technical field of automatic driving vehicle evaluation. The method comprises the steps of obtaining driving behavior information of an automatic driving vehicle on a to-be-evaluated line, calculating driving behavior characteristic parameters of the automatic driving vehicle according to the driving behavior information of the automatic driving vehicle, taking the driving behavior characteristic parameters of the automatic driving vehicle as sample points, and calculating the distance from the sample points to a reference point; according to the distance from the sample point to the reference point, the reference distance and the score corresponding to the reference distance, calculating to obtain a driving behavior score of the autonomous vehicle; wherein the smaller the distance from the sample point to the reference point is, the higher the driving behavior score of the autonomous vehicle is; the reference point is a clustering center point of a reference class, and the reference distance is a certain value in distances from clustering center points of other driving behavior classes to the reference point. According to the invention, quantitative evaluation of the driving behavior of the autonomous vehicle can be realized.
本发明提供了一种自动驾驶车辆的驾驶行为评价方法及装置，属于自动驾驶车辆评价技术领域。该方法包括：获取待评价线路上自动驾驶车辆的驾驶行为信息，根据所述自动驾驶车辆的驾驶行为信息计算得到自动驾驶车辆的驾驶行为特征参数，将自动驾驶车辆的驾驶行为特征参数作为样本点，计算样本点到参考点的距离；根据样本点到参考点的距离、基准距离和基准距离对应的分数，计算得到自动驾驶车辆的驾驶行为得分；其中，样本点到参考点的距离越小，自动驾驶车辆的驾驶行为得分越高；参考点为参考类的聚类中心点，基准距离为其他驾驶行为类别的聚类中心点到参考点的距离中的某个值。本发明能够实现对自动驾驶车辆驾驶行为的定量评价。
