The invention discloses a collision early warning method, device and equipment and a storage medium. The method comprises the following steps: acquiring the current vehicle speed of a target vehicle, determining a collision detection area according to the current vehicle speed, determining a target detection object located in the collision detection area, and calculating the collision prediction time between the target vehicle and the target detection object; determining a vehicle control state of a driver on the target vehicle and a fatigue state of the driver, and determining a collision early warning time threshold value of the target vehicle according to the vehicle control state and the fatigue state of the driver; and performing collision early warning on the target vehicle according to the collision prediction time and the collision early warning time threshold. According to the invention, collision early warning can be carried out on the target vehicle according to the determined collision prediction time, the vehicle control state of the driver on the target vehicle and the collision early warning time threshold dynamically determined by the driver, so that the effect of reducing the collision early warning false alarm rate can be achieved.

    本发明公开了一种碰撞预警方法、装置、设备及存储介质。获取目标车辆的当前车速,根据所述当前车速确定碰撞检测区域,确定位于所述碰撞检测区域内的目标检测对象,并计算所述目标车辆与所述目标检测对象之间的碰撞预测时间;确定驾驶员对所述目标车辆的车辆控制状态以及所述驾驶员的疲劳状态,根据所述车辆控制状态和所述驾驶员疲劳状态确定所述目标车辆的碰撞预警时间阈值;根据所述碰撞预测时间和所述碰撞预警时间阈值对所述目标车辆进行碰撞预警。能够根据确定的碰撞预测时间和驾驶员对所述目标车辆的车辆控制状态以及驾驶员的疲劳状态动态确定的碰撞预警时间阈值,对目标车辆进行碰撞预警,从而可以达到降低碰撞预警误报率的效果。
