The invention provides an active anti-collision early warning method and device, equipment and a storage medium, and the method comprises the steps: obtaining the current driving state of a front vehicle, the current driving speed of the front vehicle, the current driving speed of a first vehicle and a current attachment coefficient, and enabling the current attachment coefficient to be the current attachment coefficient of the first vehicle and a current road surface; determining a corresponding safety distance model according to the current driving state, and inputting at least one of the current driving speed of the front vehicle, the current driving speed of the first vehicle and the current attachment coefficient into the corresponding safety distance model to obtain a current critical safety distance between the first vehicle and the front vehicle; and according to the current critical safety distance and the current distance, executing corresponding levels of early warning, wherein the current distance is the current actual distance between the first vehicle and the preceding vehicle. According to the invention, early warning can be carried out by combining the current driving state of the front vehicle, the current driving speeds of the two vehicles and the adhesion coefficient, the early warning accuracy is high, and the safety of the system and the traffic efficiency of the road are further improved.

    本发明提供一种主动防碰撞预警方法、装置、设备和存储介质,通过获得前车的当前行驶状态、前车的当前行驶速度、第一车辆的当前行驶速度和当前附着系数,当前附着系数是第一车辆与当前路面的当前附着系数;根据当前行驶状态确定相应的安全距离模型,并将前车的当前行驶速度、第一车辆的当前行驶速度和当前附着系数中的至少一个输入至相应的安全距离模型,得到第一车辆与所述前车的当前临界安全距离;根据当前临界安全距离和当前距离,执行相应等级的预警,其中,当前距离是第一车辆与前车的当前实际距离。本发明可以结合前车的当前行驶状态、两辆车的当前行驶速度和附着系数进行预警,预警的准确率较高,进一步提高系统的安全性和道路的通行效率。
