The invention discloses a rear vehicle reminding method and system based on V2X. The method comprises the steps that positioning information of a vehicle and surrounding vehicles is monitored through open road moving high-precision data acquisition positioning equipment of each vehicle; if the distance between the front vehicle and the rear vehicle is smaller than the preset safety distance, the front vehicle intelligent driving area controller and the rear vehicle intelligent driving area controller enter a vehicle following mode; the front vehicle intelligent driving domain controller judges whether a dangerous scene occurs or not according to the vehicle driving environment information returned by the front vehicle environment sensing module; if yes, the front vehicle intelligent driving area controller sends dangerous scene information to the rear vehicle intelligent driving area controller; and the rear vehicle intelligent driving domain controller at least executes the operation of controlling and prompting the dangerous scene information. According to the rear vehicle reminding method and system based on V2X, the vehicle driving environment information sensed by the front vehicle is transmitted to the rear vehicle in time, so that the rear vehicle is reminded to carry out related operation in advance, and traffic accidents are prevented to the maximum extent.

    本发明公开了一种基于V2X的后车提醒方法及系统,所述方法包括:通过各车辆的开放道路移动高精度数采定位设备监测自身车辆与周围车辆的定位信息;若前后车的距离小于预设安全距离,则前车智能驾驶域控制器和后车智能驾驶域控制器进入跟车模式;前车智能驾驶域控制器根据前车环境感知模块所返回的车辆行驶环境信息,判断是否有危险场景发生;若是,则前车智能驾驶域控制器将危险场景信息发送到后车智能驾驶域控制器;后车智能驾驶域控制器至少执行控制提示危险场景信息的操作。本发明的基于V2X的后车提醒方法及系统,将前车所感知的车辆行驶环境信息及时传输给后车,从而提醒后车提前做出相关操作,最大限度地防止交通事故的发生。
