The invention relates to the technical field of intelligent driving, and discloses an expressway small-radius ramp vehicle-road cooperative driving early warning and afflux method, which comprises the following steps: step 1, setting information acquisition hardware facilities at ramps and a main road, obtaining identity information, weather information and ramp data of vehicles, and setting information acquisition hardware facilities at the ramps and the main road; the vehicle movement condition and position information on the main road and the ramp are collected in real time; 2, a dynamic speed limit reminding device is arranged on the ramp, the dynamic safe driving speed of the current ramp is calculated according to the ramp data and the weather information, and speed early warning is issued on the dynamic speed limit reminding device. 3, ramp vehicle convergence information is predicted, real-time collaborative marshalling is carried out on network connection vehicle segments, and ramp vehicles of each marshalling are intelligently and collaboratively converged into a main highway of the expressway; and if the vehicle is not the network connection vehicle, predicting the driving track of the vehicle through the motion condition and the position information of the vehicle on the ramp. The invention provides a method for carrying out early warning on driving at a small-radius ramp.
本发明涉及智能行车技术领域,公开了高速公路小半径匝道车路协同行车预警与汇入方法,包括以下步骤:步骤1:在匝道及主路处设置信息采集硬件设施,获取车辆的身份信息、天气信息和匝道数据,并对主路及匝道上车辆运动情况及位置信息进行实时采集;步骤2:在匝道上设置动态限速提醒装置,根据匝道数据和天气信息计算当前匝道的动态安全行驶速度,在动态限速提醒装置上发布速度预警。步骤3:预测匝道车辆汇入信息,对网联车辆分段进行实时协同编组,每一编组的匝道车辆智能协同汇入高速公路主路;如果是非网联车,通过匝道上车辆运动情况及位置信息对车辆的行驶轨迹进行预测。以提供一种在小半径匝道处对行车进行预警的方法。
