The invention discloses an urban traffic passenger car blind area early warning method and device based on vehicle-infrastructure cooperation, and belongs to the technical field of intelligent traffic. First position information of a vehicle is acquired, a vehicle coordinate system is established, and an area representative function of each sub-blind area of a vehicle fixed vision blind area under the vehicle coordinate system is acquired; a roadside sensing sensor of the position where the vehicle is located is determined through the first position information, then state information of other traffic participants in the road traffic environment of the position where the vehicle is located is obtained through the sensing sensor on the vehicle and the corresponding roadside sensing sensor, and the state information comprises second position information of the other traffic participants; the second position information of other traffic participants in the road traffic environment where the vehicle is located is converted into position information in the vehicle coordinate system; and the position information of the second position information in the vehicle coordinate system is substituted into the area representative function of the corresponding blind area according to the driving behavior of the vehicle so as to determine early warning information. According to the invention, the blind area early warning performance can be improved.
本发明公开了一种基于车路协同的城市交通客车盲区预警方法及装置,属于智能交通技术领域,获取本车的第一位置信息,建立本车坐标系,获取车辆固定视觉盲区各子盲区在本车坐标系下的区域代表函数;通过第一位置信息确定本车所处位置的路侧感知传感器,进而通过本车上的感知传感器和对应的路侧感知传感器获取本车所处位置道路交通环境中其他交通参与者的状态信息,其中,状态信息包括其他交通参与者的第二位置信息;将本车所处位置道路交通环境中其他交通参与者的第二位置信息转为本车坐标系中的位置信息;根据本车的驾驶行为将第二位置信息在本车坐标系中的位置信息代入相应盲区的区域代表函数,以确定预警信息。通过本发明可以提高盲区预警性能。
