Abstract

The invention relates to a road accident prompting method based on vehicle-road collaboration. The road accident prompting method based on vehicle-road collaboration comprises the following steps that S1, vehicles upload vehicle information to a roadside unit system periodically, the roadside unit system processes the vehicle information, and if an accident occurs, a broadcasting message of a fixed format is generated, and the message is broadcasted to travelling vehicles close to the area of the accident; S2, drivers of the travelling vehicles receiving the broadcasting message check the broadcast message list of the vehicles, and if the broadcasting message does not exist, the drivers judge the movement directions, the position relationship and the distance information of the vehicles and the vehicles in the area of the accident according to the broadcasting message, and then the drivers decide to selectively forward the message or abandon the message. Compared with the prior art, prompts can be effectively provided for following vehicles in real time by the adoption of the road accident prompting method based on vehicle-road collaboration, the spreading range is wide, the efficiency is high, the practicability is good, and popularization is easy.

Description

technical field [0001] The invention relates to an intelligent transportation technology in the Internet of Vehicles, in particular to a method for prompting sudden road accidents based on vehicle-road coordination. Background technique [0002] In terms of road traffic safety and intelligent transportation, based on vehicle-to-vehicle wireless communication, vehicle-to-roadside unit and vehicle-to-network wireless communication, the state information of all vehicles (including attribute information and static and dynamic information, etc.) Information sharing with road traffic environment information (including road infrastructure information, traffic conditions, service information, etc.), timely and credible data exchange to achieve safe and comfortable driving functions. Using the vehicle ad hoc network, combined with the vehicle's GPS and CAN bus, the safety system can notify the driver of possible dangerous situations in advance and reduce the accident rate. [0003] ...
