The invention is suitable for the technical field of intelligent driving, and provides a road obstacle sharing early warning method and system, and the method comprises the following steps: determining the current driving environment of a vehicle, and determining a reminding mode according to the current driving environment, the current driving environment being dark or bright; judging whether an obstacle exists on the road, and if so, determining the lane position of the obstacle; when the obstacle is outside the own vehicle lane or the driving area, judging whether a vehicle or a road participant exists in the obstacle lane, and when the vehicle or the road participant exists in the obstacle lane, determining a target vehicle; calculating the overlapping rate of the target vehicle and the obstacle; the running state of the target vehicle at the current moment is calculated, the collision time of the target vehicle and the obstacle is predicted, and when the collision time is smaller than a time threshold value, early warning reminding is conducted according to the reminding mode. Therefore, when the vehicle detects that the obstacle exists on the road ahead, the target vehicle or other road participants are reminded in time, and sharing early warning is carried out.
本发明适用于智能驾驶技术领域,提供了一种道路障碍物共享预警的方法及系统,包括以下步骤:确定自车当前行驶的环境,根据当前行驶的环境确定提醒方式,所述当前行驶的环境为昏暗或者明亮;判断道路是否存在障碍物,当存在障碍物时,确认障碍物的车道位置;当障碍物在自车车道以外或行驶区域以外,判断障碍物车道是否存在车辆或道路参与者,当障碍物车道存在车辆或道路参与者,确定目标车;计算目标车与障碍物的重叠率;计算当前时刻目标车的运行状态,预测目标车与障碍物的碰撞时间,当碰撞时间小于时间阈值时,根据所述提醒方式进行预警提醒。如此,当自车检测到前方道路存在障碍物时,及时提醒目标车或其他道路参与者,进行共享预警。
