The invention discloses a vehicle left turn 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; based on the vehicle end sensing data and the roadside sensing data, whether left-turning vehicles exist around the road when the main vehicle runs is judged, and the left-turning vehicles comprise non-network-connected vehicles and network-connected vehicles; if the left-turn vehicle exists, respectively predicting a motion track of the main vehicle and a motion track of the left-turn vehicle according to the vehicle end sensing data and the road side sensing data; according to the motion trail of the main vehicle and the motion trail of the left-turning vehicle, whether the main vehicle and the left-turning vehicle have a collision risk or not is judged; and if the collision risk exists, collision early warning information is sent to the main vehicle. According to the invention, the transmission time delay of data can be reduced, the real-time performance of collision early warning with the left-turning vehicle is ensured, and the communication cost can be reduced at the same time.

    本发明公开了一种车辆左转预警方法及装置,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;基于所述车端感知数据和所述路侧感知数据,判定在主车行驶时道路周围是否存在左转车辆,其中,所述左转车辆包括非网联车和网联车;若存在左转车辆,则根据所述车端感知数据和所述路侧感知数据,分别预测所述主车的运动轨迹和所述左转车辆的运动轨迹;根据所述主车的运动轨迹和所述左转车辆的运动轨迹,判定所述主车与所述左转车辆是否存在碰撞风险;若存在碰撞风险,则向所述主车发送碰撞预警信息。本发明能够降低数据的传输时延,保证与左转车辆碰撞预警的实时性,同时能够降低通信成本。
