The invention provides a traffic signal lamp issuing method, system and device based on vehicle-road cloud integration, and the method comprises the steps: obtaining the path planning information or position information and course information of a vehicle end, and obtaining the path planning information or position information and course information according to the path planning information or position information and course information; matching information of traffic lights which are about to pass within a preset vehicle driving distance; when it is sensed that the vehicle enters the preset RSU coverage range of the intersection, dynamic data source parameters of the vehicle end are obtained, and corresponding weight parameter values are calculated according to the dynamic data source parameters; and matching a corresponding traffic signal lamp information data source according to the weight parameter value, and sending traffic signal lamp information corresponding to the intersection to the vehicle through the traffic signal lamp information data source. The optimal data source is dynamically selected, it is ensured that the vehicle can obtain accurate and timely traffic signal lamp information, and the efficiency and reliability of an intelligent traffic system are improved.

    本发明提供一种基于车路云一体化的交通信号灯下发方法、系统及设备,包括,获取车辆端的路径规划信息或位置信息以及航向信息,并根据该路径规划信息或位置信息以及航向信息,匹配预设的车辆行驶距离内且将要经过的交通信号灯信息;当感知到车辆进入路口预设的RSU覆盖范围内时,获取车辆端的动态数据源参数,根据该动态数据源参数计算对应的权重参数值;并根据该权重参数值匹配对应的交通信号灯信息数据源,通过该交通信号灯信息数据源向车辆发送该路口对应的交通信号灯信息。本发明动态选择最优的数据源,确保车辆能够获取准确及时的交通信号灯信息,提升了智能交通系统的效率和可靠性。
