The invention provides a vehicle collision avoidance early warning method, device and system, and relates to the technical field of vehicle collision avoidance alarm. The vehicle collision avoidance early warning method comprises the steps of: obtaining the vehicle speed of a vehicle, the vehicle speed of a front vehicle and the vehicle distance between the vehicle and the front vehicle; determining a current working condition according to the vehicle speed of the vehicle and the vehicle speed of the front vehicle, and determining vehicle driving data under the current working condition; and determining a corresponding collision avoidance distance according to the current working condition, the vehicle driving data and preset calibration data. According to the technical scheme, whether the collision risk exists or not is judged according to the corresponding collision avoidance distance and the vehicle distance, and then the collision avoidance early warning prompt is generated to improve the vehicle driving safety.

    本发明提供了一种车辆避撞预警方法、装置及系统,涉及车辆避撞报警技术领域。本发明所述的车辆避撞预警方法,包括:获取自车车速、前车车速以及自车与前车的车距;根据所述自车车速和所述前车车速确定当前工况,并确定所述当前工况下的车辆行驶数据;根据所述当前工况、所述车辆行驶数据以及预设的标定数据确定对应的避撞距离。本发明所述的技术方案,通过根据对应的避撞距离与车距的大小判断是否存在撞车风险,进而生成避撞预警提示以提高车辆行驶安全性。
