The invention relates to an automatic driving vehicle speed control method and device, computer equipment and a storage medium, and relates to the technical field of vehicles. The method comprises the following steps: firstly, setting a speed limit value of a current vehicle in each road section of a driving lane as a first limited vehicle speed based on speed limit values of speed limit boards, then calculating a difference value of the speed limit values of the speed limit boards of adjacent road sections as a speed limit change value, and identifying target road sections with unreasonable speed limit, cliff type speed reduction and fluctuating speed limit according to the speed limit change value; the first limited vehicle speed of the target road section is corrected into a second limited vehicle speed, the second limited vehicle speed increases the range of the selectable vehicle speed, finally, a third limited vehicle speed of each road section is generated within the limited vehicle speed range of each road section based on the historical driving vehicle speed, and the third limited vehicle speed conforms to the driving habits of most users. And thirdly, the vehicle speed is limited to be in stable transition, the vehicle speed is stable within a reasonable speed limiting range, the driving efficiency is improved, the safety of intelligent driving and people driving is improved, and the comfort degree is improved.
本申请涉及一种自动驾驶车速控制方法、装置、计算机设备和存储介质,涉及车辆技术领域。首先基于限速牌限速值设置当前车辆在行使车道的每个道路段的限速值为第一限定车速,再通过计算相邻所述道路段的限速牌限速值的差值作为限速变化值,根据限速变化值识别出不合理限速、断崖式降速、起伏式限速的目标道路段,将所述目标道路段的第一限定车速修正为第二限定车速,第二限定车速增大了可选车速的范围,最后在每个道路段的限定车速范围内基于历史驾驶车速生成每个道路段的第三限定车速,第三限定车速符合大部分用户驾驶习惯,且第三限定车速平稳过渡,在合理限速范围内使车速平稳,提升行驶效率,提升智驾和人驾的安全性,提升舒适度。
