The embodiment of the invention provides a driving speed judgment method and device, equipment and a storage medium, and relates to the technical field of driving safety. The method for judging the running speed comprises the following steps of: S1, acquiring the distance between a vehicle and a front vehicle, and the running speed of the vehicle; S2, acquiring the friction force between the vehicle and the road surface; S3, according to the distance and the friction force, calculating the safety speed of the vehicle based on energy conservation; S4, judging whether the driving speed is greater than the safe vehicle speed; and S5, when it is judged that the driving speed is larger than the safe vehicle speed, generating and outputting alarm information. The safe vehicle speed is judged through the friction force and the vehicle following distance, and vehicle following conditions under various road conditions can be adapted. And traffic accidents caused by overspeed are effectively avoided.

    本发明实施例提供一种行车速度的判断方法、装置、设备和存储介质,涉及行车安全技术领域。其中,这种行车速度的判断方法,其包含S1、获取自车和前车之间的距离,以及自车的行驶速度。S2、获取自车和路面之间的摩擦力。S3、根据距离和摩擦力,基于能量守恒,计算自车的安全车速。S4、判断行驶速度是否大于安全车速。S5、当判断到行驶速度大于安全车速时,生成并输出警报信息。通过摩擦力和跟车距离来判断安全车速,能够适应各种路况下的跟车情况。有效的避免了,应超速而引起的交通事故。
