The invention discloses a non-signalized intersection early warning system and early warning method based on vehicle cloud collaboration, and the method comprises the steps: enabling a to-be-early-warned vehicle to be driven into a non-signalized intersection range, and uploading the parameters of the vehicle to a cloud database through a vehicle main control chip; other vehicles upload navigation routes to the cloud database through the vehicle machine main control chip; the central processing unit compares the collected navigation routes of other vehicles with the advancing direction of the vehicle to be pre-warned, distinguishes threatening vehicles and irrelevant vehicles according to whether route nodes intersect or not, and then performs threat priority level division on the screened threatening vehicle data set according to a preset rule base; and finally, according to the threat priority level, carrying out corresponding early warning prompt through a vehicle meeting early warning prompt module. The judgment method is simple and effective, the real-time effectiveness of feedback is improved while the cost is reduced, and vehicle accidents frequently occurring at the non-signalized intersection due to the reasons such as the limited view field and the complex environment are effectively prevented.

    本发明公开了一种基于车云协同的无信号交叉口预警系统及预警方法,包括待预警车辆用于驶入无信号交叉口范围内,并通过车机主控芯片将自身参数上传至云端数据库;其他车辆通过车机主控芯片用于将导航路线上传到云端数据库;中央处理单元将收集的其他车辆的导航路线与待预警车辆自身行进方向作比较,根据路线节点是否有交汇来区分威胁车辆及不相关车辆,再将筛选出来的威胁车辆数据集根据预设规则库进行威胁优先等级划分,最后根据威胁优先等级的高低通过会车预警提示模块进行相应的预警提示。本发明判定方法简单有效,减少成本的同时提高了反馈的实时有效性,有效预防由于视野受限,环境复杂等原因在无信号交叉口频发的车辆事故。
