The invention discloses a vehicle speed prediction method. The method can be applied to the technical field of intelligent driving, and specifically comprises the following steps: processing historical vehicle speed information of a target vehicle at each historical moment in a historical time period according to global vehicle speed characteristics of the target vehicle in the historical time period to obtain vehicle speed aggregation characteristics of the target vehicle at each historical moment; processing the historical acceleration information of the target vehicle at each historical moment according to the global acceleration characteristics of the target vehicle at the historical time periods to obtain acceleration aggregation characteristics of the target vehicle at each historical moment; and predicting the future vehicle speed of the target vehicle at the future moment according to the first similarity between the vehicle speed aggregation features, the vehicle speed aggregation features, the second similarity between the acceleration aggregation features and the acceleration aggregation features. Based on the method and the device, the finally predicted future vehicle speed is more accurate, and the predicted future vehicle speed is higher in reference value.
本申请公开了一种车速预测方法。该方法可应用于智能驾驶技术领域,具体可以包括:根据目标车辆在历史时段的全局车速特征,对目标车辆在历史时段内各历史时刻的历史车速信息进行处理,得到目标车辆在各历史时刻的车速聚合特征;根据目标车辆在历史时段的全局加速度特征,对目标车辆在各历史时刻的历史加速度信息进行处理,得到目标车辆在各历史时刻的加速度聚合特征;根据各车速聚合特征之间的第一相似度和各车速聚合特征,以及各加速度聚合特征之间的第二相似度和各加速度聚合特征,预测目标车辆在未来时刻的未来车速。基于本申请,使得最终预测得到的未来车速更加准确,也使的预测得到的未来车速更具参考价值。
