Vehicle lane changing early warning method and device based on V2V

Abstract

The invention discloses a vehicle lane changing early warning method based on Vehicle to Vehicle (V2V). The vehicle lane changing early warning method comprises the steps that firstly, confirming an automobile located in front of a vehicle on an adjacent lane of the automobile; calculating danger coefficients of adjacent lanes; and finally, judging whether the vehicle in front of the vehicle on the adjacent lane of the vehicle changes the lane with high probability or not; and if yes, sending an early warning of large-probability lane changing of the vehicle on the adjacent lane to the driver of the vehicle. The invention further discloses a lane changing early warning device which is used for implementing the lane changing early warning method and comprises a V2V communication unit, a central processing unit and an indicator light unit. An OBD module, a GPS module and a V2V information interaction module are arranged in the V2V communication unit; and a vehicle position generation module, an adjacent lane danger coefficient calculation module and a lane change judgment module are arranged in the central processing unit. According to the invention, the probability of traffic accidents caused by collision between the vehicle on the adjacent lane and the own vehicle in the process of changing the lane to the current lane of the own vehicle can be remarkably reduced.

Description

technical field [0001] The present invention relates to the technical field of active early warning for vehicle driving, in particular to a vehicle lane change early warning method and device based on Vehicle to Vehicle (V2V). Background technique [0002] Lane-changing behavior is very common in the process of road driving. Lane-changing can be decomposed into lateral motion and longitudinal motion, so lane-changing behavior is a relatively complicated driving behavior; not only that, drivers often It is because of the complexity of the surrounding environment that the idea of ​​changing lanes arises, that is, there is an intention to change lanes; at the same time, changing lanes will also cause the surrounding environment to become complicated. Therefore, in road traffic accidents, lane changing behavior is also one of the important reasons. And there is a common lane-changing accident manifestation as: the driving vehicle collides with the vehicle at the rear in the lan...

Problems solved by technology

[0003] At present, researchers at home and abroad have carried out relevant research on the danger judgment in the process of changing lanes and the warning system for changing lanes. Most of the research is to analyze the feasibility of changing lanes for self-vehicles, starting from the perspective of changing lanes. Only the influence of the surrounding vehicles on the lane change of the own vehicle is considered, and only the safety of the lane change of the own vehicle is guaranteed. However, for the vehicles driving on the road, this consideration is one-sided, ignoring the fact that when the own vehicle is driving on the road, The influence of surrounding vehicles changing lanes on their own normal and safe driving, this influence will also lead to the way of lane changing traffic accidents
