The invention discloses a road speed limit information determination method, a vehicle-mounted control system, a vehicle and a medium. The method comprises the following steps: acquiring track data of all vehicles in a plurality of road sections in a preset time period; the traffic jam speed and the speeds of other vehicles on a non-target road section are removed from the trajectory data, and effective speed information on the target road section is obtained; and determining target road speed limit information corresponding to the target road section by using the effective speed information. In this way, the reasonability and accuracy of the road speed limit information can be improved.

    本申请公开了道路限速信息的确定方法、车载控制系统、车辆、介质。该方法包括:获取若干路段在预设时间段内所有车辆的轨迹数据;从轨迹数据中剔除堵车速度以及非目标路段的其他车辆速度,得到目标路段上的有效速度信息;利用有效速度信息确定出目标路段对应的目标道路限速信息。通过上述方式,能够提高道路限速信息的合理性以及准确性。
