The invention relates to a vehicle line pressing early warning method and system based on V2X, a medium and a vehicle-mounted terminal. The method comprises the following steps: receiving a lane marking message sent by an RSU; wherein the lane marking information at least comprises position information and type information of a plurality of discrete points of at least one lane marking; acquiring the position information of the vehicle; according to the lane marking information and the position information of the vehicle, determining whether the vehicle illegally presses the line or does not illegally press the line; when it is determined that the vehicle does not illegally press the line, first-level early warning prompt information is output or line pressing early warning prompt information is not output; and when it is determined that the vehicle illegally presses the line, outputting second-level early warning prompt information. According to the invention, the technical problems of low accuracy and high misjudgment rate of current vehicle line pressing early warning can be solved.
本发明涉及基于V2X实现的车辆压线预警方法与系统、介质、车载终端,包括:接收RSU发送的车道标线消息;其中,所述车道标线消息至少包括至少一条车道标线的多个离散点位置信息和种类信息;获取本车位置信息;根据所述车道标线消息和所述本车位置信息确定本车是否违规压线或非违规压线;当确定本车非违规压线时,输出第一级预警提示信息或不输出压线预警提示信息;当确定本车违规压线时,输出第二级预警提示信息。通过本发明,能够解决目前车辆压线预警的准确性低和误判率高的技术问题。
