The invention discloses a vehicle early warning method, device and equipment and a medium. The method comprises the steps that when a vehicle to be pre-warned enters a designated area, vehicle position information of the vehicle to be pre-warned, vehicle state information of surrounding vehicles and preset area grade information of the designated area are acquired; according to the preset area grade information, the vehicle position information and the vehicle state information, determining a target vehicle meeting an early warning condition and corresponding early warning event intensity information; and issuing the early warning event intensity information to the to-be-early-warned vehicle. According to the invention, region grade division is carried out on a vehicle to be pre-warned and surrounding vehicles meeting pre-warning conditions through preset region grade information, then pre-warning event intensity information is determined through divided region grades, and pre-warning is carried out on the vehicle to be pre-warned with different pre-warning intensities. Real-time sensing and prediction of abnormal driving behaviors are realized, and differentiated information prompting and early warning are realized. The safety risk near the exit ramp of the expressway is reduced, and the passing efficiency is improved.

    本发明公开了一种车辆预警方法、装置、设备及介质。该方法包括:当待预警车辆进入指定区域时,获取待预警车辆的车辆位置信息、周边车辆的车辆状态信息,以及指定区域的预设区域等级信息;根据预设区域等级信息、车辆位置信息及车辆状态信息,确定满足预警条件的目标车辆及对应的预警事件强度信息;将预警事件强度信息下发至待预警车辆。通过预设区域等级信息对待预警车辆及满足预警条件的周边车辆进行区域等级划分,进而通过划分处的区域等级确定预警事件强度信息,以不同的预警强度向待预警车辆进行预警。实现了对异常驾驶行为的实时感知与预测,实现了差异化的信息提示和预警。降低了高速公路出口匝道附近的安全风险,并提升通行效率。
