The invention relates to a vehicle lane changing intention interaction method and system based on visible light communication, and the method comprises the steps: enabling a steering lamp to flicker after a driver has a lane changing intention and dials the steering lamp of a vehicle to be subjected to lane changing, and judging whether the vehicle to be subjected to lane changing meets a lane changing condition or not through vehicle collision early warning and lane line recognition; if the to-be-lane-changed vehicle meets the lane changing condition, basic information of the to-be-lane-changed vehicle is collected in real time; the basic information of the vehicle waiting for lane changing is processed for the first time, and the basic information, processed for the first time, of the vehicle waiting for lane changing is transmitted outwards through a visible light signal; receiving a visible light signal captured by the vehicle, and processing the visible light signal for the second time to obtain basic information of the vehicle to be lane-changed; and the receiving vehicle judges whether collision risks exist between the receiving vehicle and the to-be-lane-changed vehicle or not according to the obtained basic information of the to-be-lane-changed vehicle, and the driving speed is controlled according to the collision risks. The vehicle lane changing intention interaction is realized by using the visible light communication technology, and the method can be widely popularized and used.
本发明涉及一种基于可见光通信的车辆换道意图交互方法和系统,方法包括:当驾驶员具有换道意图并拨动待换道车辆的转向灯后,转向灯闪烁,通过车辆碰撞预警和车道线识别来判断待换道车辆是否满足换道条件;若待换道车辆满足换道条件,则实时采集待换道车辆基本信息;对所述待换道车辆基本信息进行第一次处理,并将第一次处理后的待换道车辆基本信息通过可见光信号向外传输;接收车辆捕获到可见光信号,并将可见光信号进行第二次处理得到待换道车辆基本信息;接收车辆根据得到的待换道车辆基本信息判断自身和待换道车辆是否存在碰撞风险,并根据碰撞风险控制行驶速度。本发明使用可见光通信技术实现车辆换道意图交互,能够广泛推广使用。
