The invention relates to a blind area monitoring and early warning method and system, and belongs to the technical field of intelligent traffic technology and traffic safety guarantee. The method comprises the following steps that: a vehicle-mounted monitoring host acquires a running track of an obstacle in front of a vehicle and a running track of the vehicle according to information of the obstacle in front of the vehicle in a blind area and running data of the vehicle, and an intersection point exists between the running track of the obstacle in front of the vehicle and the running track of the vehicle; estimating the distance between the obstacle and the intersection when the vehicle arrives at the intersection and the relative position relation between the obstacle and the running track of the vehicle, and executing corresponding blind area collision treatment measures according to the distance and the relative position relation. The system comprises a roadside sensing unit, a roadside communication unit, a vehicle-mounted communication unit and a vehicle-mounted monitoring host for implementing the method. The roadside sensing unit is used for detecting obstacle information in a blind area, and the roadside communication unit and the vehicle-mounted communication unit are used for transmitting the obstacle information. Whether a collision risk exists between the vehicle and the obstacle or not can be accurately judged, and the vehicle safety is improved.

    本发明涉及一种盲区监测及预警方法及系统,属于智能交通技术及行车安全保障技术领域。该方法为:车载监控主机根据盲区内车辆前方的障碍物信息和自车运行数据,获取前方障碍物的运行轨迹与自车运行轨迹,当前方障碍物的运行轨迹与自车运行轨迹存在交叉点,预估车辆到达交叉点时障碍物与交叉点的距离以及障碍物与自车运行轨迹的相对位置关系,根据距离和相对位置关系执行相应的盲区碰撞处理措施。该系统包括路侧感知单元、路侧通信单元、车载通信单元和用于实现上述方法的车载监控主机;路侧感知单元用于检测盲区内的障碍物信息,路侧通信单元和车载通信单元用于传输障碍物信息。本发明能够准确判断车辆与障碍物是否存在碰撞风险,提高车辆安全性。
