The invention relates to a road danger early warning and vehicle speed control system under vehicle-road cooperation. The road danger early warning and vehicle speed control system comprises a road side unit RSU, a vehicle-mounted unit OBU, a safe distance control module, a danger early warning module and a vehicle speed control module. The road danger early warning and vehicle speed control method under vehicle-road cooperation is developed in combination with the control system, data interaction between vehicles and roads and data interaction between the vehicles are achieved through the vehicle-road cooperation technology so as to obtain more comprehensive information, and on the premise that safe driving of the vehicles is guaranteed, speed limiting and braking factors of the front vehicle and the rear vehicle are combined, so that the driving safety of the vehicles is guaranteed. And the calculation of the safe distance is adjusted, and the control of the speed of the rear vehicle is determined, so that relatively high traffic safety and traffic passing efficiency are ensured.
本发明涉及一种车路协同下道路危险预警与车速控制系统,包括路侧单元RSU,车载单元OBU,安全距离控制模块,危险预警模块,以及车速控制模块;并结合上述控制系统研制了一种车路协同下道路危险预警与车速控制方法,通过车路协同技术实现车路间的数据交互与车辆间的数据交互,以获取更全面的信息,在保证车辆安全行驶的前提下,结合限速与前车、后车制动因素,对安全距离的计算进行调整,确定后车车速的控制,以保证较高的交通安全性和交通通行效率。
