The invention discloses a mileage prediction method and device and a medium. The method comprises the following steps: acquiring a target historical path from a database; wherein the database comprises different historical driving paths composed of historical driving mileages and historical longitudes and latitudes; and taking the historical driving mileage corresponding to the target historical path as the target predicted mileage. In the vehicle driving process, whether the target historical path is consistent with the actual driving path or not is judged, and when the target historical path is not consistent with the actual driving path, deviation correction is conducted on the target predicted mileage according to the historical driving mileage and the historical longitude and latitude. Therefore, real-time prediction and deviation correction are carried out on the driving mileage through the historical driving mileage and the historical longitude and latitude without depending on navigation, and normal prediction can still be carried out even under the condition of no signal or weak signal. In addition, the method only depends on prediction of historical mileage and historical longitude and latitude, so that computing resources are greatly saved, an algorithm is easy to deploy on resource-limited equipment, and user experience is improved.

    本申请公开了一种行驶里程的预测方法、装置及介质,该方法包括:从数据库中获取目标历史路径;其中,数据库包括由历史行驶里程和历史经纬度构成的不同历史行驶路径;并将目标历史路径对应的历史行驶里程作为目标预测里程。在车辆行驶过程中,判断目标历史路径与实际行驶路径是否一致,当目标历史路径与实际行驶路径不一致时,根据历史行驶里程和历史经纬度,对目标预测里程进行纠偏。由此,通过历史行驶里程和历史经纬度对行驶里程进行实时预测和纠偏,无需依赖导航,即使在无信号或信号弱的情况下,依旧可以正常预测。此外,仅依赖于历史行驶里程和历史经纬度的预测,大幅度节约了计算资源,使算法易于在资源受限的设备上部署,提升用户体验。
