The invention discloses a lane changing risk early warning method and device, and belongs to the technical field of vehicles. A specific embodiment of the method comprises the following steps: acquiring airflow pressure detection data in a preset range of the outer side of a first vehicle; determining a pressure change path according to the pressure detection data; determining a lane changing intention of a second vehicle corresponding to the first vehicle according to the pressure change path; and according to the lane changing intention, a lane changing risk early warning prompt is sent out, so that collision between the first vehicle and the second vehicle is avoided. According to the embodiment, the lane changing intention of the surrounding vehicles is determined according to the airflow pressure data of the outer side of the vehicle, early warning prompt is given to the driver, and therefore the driver is assisted to control the vehicle, the occurrence rate of collision accidents caused by lane changing is reduced, and the driving safety is improved.

    本发明公开了一种变道风险预警方法及装置,属于车辆技术领域。该方法的一具体实施方式包括:获取第一车辆外侧预设范围内的气流压力检测数据;根据所述压力检测数据,确定压力变化路径;根据所述压力变化路径,确定所述第一车辆对应的第二车辆的变道意图;根据所述变道意图,发出变道风险预警提示,以避免所述第一车辆与所述第二车辆发生碰撞。该实施方式通过车辆外侧的气流压力数据确定周围车辆的变道意图,并对驾驶员进行预警提示,从而辅助驾驶员进行车辆控制,降低了变道导致的碰撞事故发生率,提高了行车安全性。
