The invention discloses an automatic driving control method based on vehicle-road cooperation traffic light information, and belongs to the technical field of automatic driving, and the method comprises the following steps: 1) a roadside system obtains traffic light information, processes the traffic light information, and sends the processed data to an OBU; 2) the OBU receives the data sent by the roadside system, matches the received data with the positioning information data acquired by the OBU, and processes the matched data; based on the V2X technology, the road side system obtains the traffic light information in front of the running vehicle in real time, the traffic light data is received by the OBU of the passing vehicle after processing, the OBU processes the data and sends the data to the automatic driving software, the optimal intersection passing scheme is decided by using the AI algorithm, the state of the traffic light does not need to be recognized through images in the process, and the traffic light passing efficiency is improved. The automatic driving vehicle can pass through the intersection stably and safely in a green wave mode, and the danger degree when the vehicle passes through the intersection is greatly reduced.

    本发明公开了一种基于车路协同红绿灯信息的自动驾驶控制方法,属于自动驾驶技术领域,包括如下步骤:1)路侧系统获取红绿灯信息,路侧系统将红绿灯信息进行处理,并将处理后的数据发送给OBU;2)OBU接收到路侧系统发送的数据,OBU将收到的数据与自身获取的定位信息数据相匹配,将匹配的数据进行处理;本发明通过基于V2X技术,路侧系统实时获取车辆运行前方红绿灯信息,经过处理后将红绿灯数据被过往车辆的OBU接收,OBU将数据进行处理后发送至自动驾驶软件,利用AI算法决策出最佳的通过路口方案,过程中,无需依赖通过图像识别出红绿灯状态,可实现自动驾驶车辆绿波、平稳、安全的通过路口,极大的减低在路口通过时的危险程度。
