The invention relates to a vehicle door opening anti-collision early warning method based on V2X. The method comprises the steps of obtaining driving parameters periodically broadcasted by surrounding vehicles and non-motor vehicles/pedestrians, and the driving parameters at least comprising position information, speed, acceleration and driving tracks; acquiring driving parameters of the current vehicle; screening out surrounding vehicles and non-motor vehicles/pedestrians which have a crossing and overlapping area with the current vehicle driving track; judging whether the crossing and overlapping area covers the position information of the current vehicle or not, and if yes, taking surrounding vehicles and non-motor vehicles/pedestrians corresponding to the crossing and overlapping area covering the position information of the current vehicle as dangerous targets; judging whether the current vehicle is in a static state or not, and if yes, sending an early warning signal to the current vehicle; or else, not giving an early warning prompt. According to the method, non-motor vehicles/pedestrians and traffic participants without V2X equipment can be considered in scene calculation, the defects existing in an existing vehicle door collision prediction method are overcome, and potential accidents can be eliminated.

    本发明涉及一种基于V2X的车辆开门防碰撞预警方法,该方法包括:获取周边车辆及非机动车/行人周期性广播的行驶参数,行驶参数至少包括位置信息、速度、加速度以及行驶轨迹;获取当前车辆的行驶参数;筛选出与当前车辆行驶轨迹存在交叉重叠区域的周边车辆、非机动车/行人;判断交叉重叠区域是否覆盖当前车辆的位置信息,若是,将覆盖当前车辆位置信息的交叉重叠区域所对应的周边车辆、非机动车/行人作为危险目标;判断当前车辆是否处于静止状态,若是,向当前车辆发出预警信号;否则,不做预警提示。该方法能将非机动车/行人以及未安装V2X设备的交通参与者均考虑在场景计算中,弥补现有车门碰撞预测方法存在的缺陷,利于消除事故隐患。
