The invention discloses a vehicle lane changing early warning method based on Vehicle to Vehicle (V2V). The vehicle lane changing early warning method comprises the steps that firstly, confirming an automobile located in front of a vehicle on an adjacent lane of the automobile; calculating danger coefficients of adjacent lanes; and finally, judging whether the vehicle in front of the vehicle on the adjacent lane of the vehicle changes the lane with high probability or not; and if yes, sending an early warning of large-probability lane changing of the vehicle on the adjacent lane to the driver of the vehicle. The invention further discloses a lane changing early warning device which is used for implementing the lane changing early warning method and comprises a V2V communication unit, a central processing unit and an indicator light unit. An OBD module, a GPS module and a V2V information interaction module are arranged in the V2V communication unit; and a vehicle position generation module, an adjacent lane danger coefficient calculation module and a lane change judgment module are arranged in the central processing unit. According to the invention, the probability of traffic accidents caused by collision between the vehicle on the adjacent lane and the own vehicle in the process of changing the lane to the current lane of the own vehicle can be remarkably reduced.

    本发明公开了一种基于Vehicle to Vehicle(V2V)的汽车换道预警方法:首先确认自车相邻车道上位于自车前方的车辆;然后计算相邻车道的危险系数;最后判断自车相邻车道上位于自车前方的车辆是否会大概率换道;若是,对自车驾驶人发出相邻车道上车辆大概率换道的预警。还公开一种道预警装置,用于实施上述换道预警方法,包括:V2V通信单元、中央处理单元和指示灯单元;V2V通信单元内设置有OBD模块、GPS模块和V2V信息交互模块;中央处理单元内设置有车辆位置生成模块、相邻车道危险系数计算模块和换道判断模块。本发明可显著降低相邻车道上的车辆换道至自车当前车道的过程中与自车发生碰撞交通事故的概率。
