The embodiment of the invention provides a vehicle driving risk early warning method and device. The early warning method comprises the steps: calculating a first driving risk value of a target vehicle according to driving parameters of the target vehicle; obtaining a first probability that a traffic accident happens to a road where the target vehicle is located due to a road surface obstacle; according to the first probability, calculating a second probability that driving of other vehicles in a predetermined range behind the target vehicle is influenced by the road surface obstacle; if the sum of the second probabilities of the other vehicles is greater than or equal to the first driving risk value, carrying out early warning on the target vehicle when the target vehicle is driven away from the area where the road surface obstacle is located. According to the technical scheme, the attention degree of a target vehicle driver to a dangerous road section can be improved, and the early warning effect is ensured.

    本申请的实施例提供了一种车辆驾驶风险的预警方法及装置。该预警方法包括:根据目标车辆的行驶参数,计算所述目标车辆的第一驾驶风险值;获取所述目标车辆所在的道路因路面障碍物发生交通事故的第一概率;根据所述第一概率,计算位于所述目标车辆之后预定范围内的其他车辆被所述路面障碍物影响行驶的第二概率;若所述其他车辆的所述第二概率之和大于或等于所述第一驾驶风险值,则在所述目标车辆驶离所述路面障碍物所在区域时,对所述目标车辆进行预警。本申请实施例的技术方案可以提高目标车辆驾驶人员对危险路段的重视程度,保证预警效果。
