The invention discloses a vehicle collision early warning method, device and equipment and a storage medium. The method comprises the following steps: acquiring vehicle association information, and determining a second vehicle driving to the same intersection as a first vehicle by using the vehicle association information; if the first vehicle turns at the intersection and has the right-of-way conflict with the second vehicle, determining predicted driving tracks of the first vehicle and the second vehicle by using a lane end point position of an associated lane of the intersection; and determining whether the first vehicle and the second vehicle have a collision risk or not according to the predicted driving track, and if yes, determining a collision early warning opportunity according to the early warning delay multiplying power and the distance between the first vehicle and the second vehicle and the collision risk point. According to the technical scheme provided by the embodiment of the invention, the two vehicles driving to the same intersection are accurately determined by using the vehicle association information, the driving tracks of the vehicles are predicted by using the lane end points of the intersection, and accurate collision early warning of the vehicles driving to the intersection can be realized according to the tracks.

    本发明公开了一种车辆碰撞预警方法、装置、设备及存储介质。该方法包括:获取车辆关联信息,并利用车辆关联信息确定与第一车辆驶向同一交叉路口的第二车辆;若第一车辆在交叉路口转向且与第二车辆存在路权冲突,则利用交叉路口关联车道的车道终点位置确定第一车辆和第二辆车的预测行驶轨迹;根据预测行驶轨迹确定第一车辆与第二车辆是否存在碰撞风险,若存在,则根据预警延后倍率以及第一车辆和第二车辆距碰撞风险点的距离确定进行碰撞预警的时机。本发明实施例的技术方案,利用车辆关联信息准确的确定了驶向同一交叉路口的两车,并利用交叉路口的车道终点预测了车辆的行驶轨迹,根据该轨迹即可实现准确的对驶向交叉路口的车辆的碰撞预警。
