The invention discloses an automatic driving speed planning method and device based on an empirical road section, a medium and equipment, and belongs to the technical field of automatic driving. The method mainly comprises the following steps: positioning and identifying a current road section to obtain current road section positioning and identifying information; querying a record of the historical driving speed of the current road section corresponding to the positioning identification information of the previous road section from a historical driving speed record library pre-established by the automatic driving vehicle; if the record of the historical driving speed of the current road section exists in the historical road section driving speed record library, a current planning strategy is obtained according to the record of the historical driving speed of the current road section, and then speed planning is conducted on the automatic driving vehicle according to the current planning strategy; and iteratively updating the historical driving speed record library according to the current driving speed of the automatic driving vehicle driving on the current road section and the current road section positioning identification information. According to the invention, operation resources during speed planning can be saved, the system response is improved, and the speed planning efficiency is improved.

    本申请公开了一种基于经验路段的自动驾驶速度规划方法、装置、介质及设备,属于自动驾驶技术领域。主要包括,对的当前路段进行定位识别得到当前路段定位识别信息;从自动驾驶车辆预先建立的历史行驶速度记录库中,查询与前路段定位识别信息对应的当前路段历史行驶速度的记录;若历史路段行驶速度记录库中存在当前路段历史行驶速度的记录,则根据当前路段历史行驶速度的记录得到当前规划策略,进而根据当前规划策略对自动驾驶车辆进行速度规划;以及根据自动驾驶车辆在当前路段行驶的当前行驶速度,以及当前路段定位识别信息对历史行驶速度记录库进行迭代更新。本申请能够节约速度规划时的运算资源,提高系统反应相应,提高速度规划效率。
