The vehicle control delay prediction method based on the hypergraph model is suitable for the automatic driving technology in the field of intelligent traffic. Firstly, different from a traditional graph model, a hyperedge defined by a hypergraph can be connected with two or more track points so as to encode a high-order relationship between the track points; secondly, a hyperedge is constructed through dense neighborhood search based on multi-core trajectory similarity, and the connection strength between trajectory points is described more accurately; and by adding road network constraints, the prediction trajectory is constrained in a road feasible region range, so that the accuracy of the prediction result is further improved. The technical problems mainly solved by the invention are as follows: (a) the accuracy of a trajectory prediction result is improved; (b) the parameter training cost is reduced; and (c) the accuracy and the calculation efficiency of a control delay prediction result are improved.
基于超图模型的车辆控制延误预测方法适用于智能交通领域中的自动驾驶技术。首先,与传统的图模型不同,超图所定义的超边可以连接两个及以上轨迹点,以此来编码轨迹点之间的高阶关系;其次,通过基于多核轨迹相似性的密集邻域搜索来构建超边,更准确地刻画轨迹点之间的连接强度;通过添加路网约束,将预测轨迹约束在道路可行域范围内,进一步提高预测结果的准确性。本发明主要解决的技术问题包括:(a)提高了轨迹预测结果的准确性;(b)降低了参数训练成本;(c)提高了控制延误预测结果的准确性和计算效率。
