The invention relates to a V2X-based early warning method for avoiding vulnerable traffic participants. The method comprises the steps of obtaining motion state information of the vulnerable traffic participants, and calculating position information of the vulnerable traffic participants after preset time; obtaining motion state information of the vehicle, and calculating position information of the vehicle after preset time; comparing to obtain the relative distance between the vehicle and the vulnerable traffic participant after the preset time; judging whether the relative distance is smaller than a minimum safety threshold value or not; if yes, the collision danger exists; if not, the collision danger does not exist; the information of the vulnerable traffic participants is sent to surrounding vehicles through the RSU; whether a potential collision risk exists or not is judged according to the RSU messages received by the surrounding vehicles through the movement information and the movement tracks of the surrounding vehicles and the movement tracks of the vulnerable traffic participants so that collision early warning is conducted on vehicle drivers, traffic accidents and secondary injuries are reduced, and the driving safety or the passing efficiency is improved.
本发明涉及一种基于V2X的避让弱势交通参与者的预警方法包括获取弱势交通参与者的运动状态信息,推算弱势交通参与者在预设时间后的位置信息;获取本车的运动状态信息,推算本车在预设时间后的位置信息;比对得出在预设时间后本车与弱势交通参与者的相对距离;判断相对距离是否小于最小安全阈值,若是,则存在碰撞危险,若否,则不存在碰撞危险,通过RSU将弱势交通参与者信息发送给周围车辆,周围车辆接收到的RSU消息,通过自身运动信息、轨迹和弱势交通参与者的运动轨迹,判断是否有潜在的碰撞风险,从而对车辆驾驶员进行碰撞预警,减少交通事故和二次伤害,提高行车安全或通行效率。
