Abstract

The invention provides a vehicle collision early warning processing method and device, and the method comprises the steps: obtaining vehicle information and road network information of a current vehicle and a target vehicle, and carrying out the road network matching of the current vehicle and the target vehicle according to the vehicle information and the road network information; if a road network matching result is that the target vehicle is in front of the current vehicle and is located in the same road section lane, establishing a vehicle body coordinate system of the current vehicle, anddetermining a coordinate set of a predicted trajectory of the current vehicle within a predetermined time; determining that the current vehicle has a collision risk with the target vehicle accordingto a coordinate set of the predicted trajectory of the current vehicle; according to the method, the problem that the way of determining collision risk by calculating the safe vehicle distance betweenthe vehicle and the surrounding adjacent vehicles based on the positioning information of the vehicle in the prior art cannot be suitable for forward collision early warning in a curve scene can be solved, and the method can be well compatible with forward collision scenes of a straight road and a curve.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a vehicle collision early warning processing method and device. Background technique [0002] With the acceleration of urbanization, the traffic network is becoming more and more complex, and the occurrence of various traffic accidents is becoming more and more frequent. How to effectively avoid the occurrence of traffic collision accidents is also an urgent problem in the field of intelligent transportation. [0003] In recent years, with the rapid development of science and technology, vehicles and vehicles (V2V), vehicles and pedestrians (V2P), and vehicles and transportation facilities (V2I) are connected to each other, forming a car networking technology that connects cars, pedestrians and infrastructure to solve road problems. The problem of traffic safety points out the direction, that is, through the Internet of Vehicles technology, the vehicle can obtain the inf...
