The invention discloses a vehicle collision early warning method and device, and relates to the technical field of intelligent networking, and the method comprises the steps: obtaining vehicle end sensing data and road side sensing data; fusing the vehicle end sensing data and the road side sensing data to respectively obtain a first feature data set of the vehicle at the current moment and a second feature data set of the target object at the current moment; based on the first feature data set and the second feature data set, respectively predicting a motion track of the vehicle and a motion track of the target object; according to the motion trail of the vehicle and the motion trail of the target object, whether the vehicle and the target object have a collision risk at the next moment of the current moment or not is judged; and if the collision risk exists, collision early warning information is sent to the vehicle. According to the invention, the transmission delay of data can be reduced, the real-time performance of collision early warning is ensured, and the communication cost can be reduced at the same time.
本发明公开了一种车辆碰撞预警方法及装置,本发明涉及智能网联技术领域,其中包括:获取车端感知数据和路侧感知数据;对所述车端感知数据和所述路侧感知数据进行融合,分别得到车辆在当前时刻的第一特征数据集和目标对象在当前时刻的第二特征数据集;基于所述第一特征数据集和所述第二特征数据集,分别预测所述车辆的运动轨迹和所述目标对象的运动轨迹;根据所述车辆的运动轨迹和所述目标对象的运动轨迹,判定所述车辆与所述目标对象在所述当前时刻的下一时刻是否存在碰撞风险;若存在碰撞风险,则向所述车辆发送碰撞预警信息。本发明能够降低数据的传输时延,保证碰撞预警的实时性,同时能够降低通信成本。
