The invention discloses a vehicle collision early warning method, a vehicle collision early warning device, vehicle collision early warning equipment and a medium. Based on detection data of a vehicle-mounted sensor, an optimal estimation value of first motion data of the first vehicle at the current moment and an optimal estimation value of second motion data of the second vehicle at the current moment are determined through a PID adaptive Kalman filtering algorithm, wherein the detection data of the vehicle-mounted sensor are obtained through a V2X technology; based on the optimal estimation value of the first motion data and the optimal estimation value of the second motion data, whether the first vehicle and the second vehicle will collide at the future moment or not is determined, and collision early warning information is sent to the first vehicle and the second vehicle respectively. The accuracy of vehicle collision early warning is improved, the potential collision risk can be predicted more accurately, and the situations of false early warning and missed early warning are reduced.

    本发明公开一种车辆碰撞预警方法、装置、设备和介质,方法包括:当监测到第一车辆与第二车辆之间的距离为预警距离时,基于车载传感器的检测数据通过PID自适应卡尔曼滤波算法分别确定第一车辆在当前时刻的第一运动数据的最优估计值以及第二车辆在当前时刻的第二运动数据的最优估计值,所述车载传感器的检测数据是通过V2X技术获取的;基于所述第一运动数据的最优估计值以及所述第二运动数据的最优估计值确定所述第一车辆与所述第二车辆在未来时刻是否会发生碰撞,并向所述第一车辆和所述第二车辆分别发送碰撞预警信息。提高了车辆碰撞预警的准确性,能够更准确地预测潜在的碰撞风险,减少误预警和漏预警的情况。
