Forward anti-collision method, system and device based on vehicle-to-vehicle communication and storage medium

Abstract

The invention provides a forward anti-collision method and system based on vehicle-to-vehicle communication. The method comprises the steps of determining the vehicle speed v of a vehicle and the yaw velocity omega in the three-dimensional angular velocity of the vehicle, determining a road curvature k of a driving road of the vehicle based on the vehicle speed v and the yaw velocity omega, determining a curvature radius r based on the road curvature k, and determining a driving path of the vehicle based on the curvature radius r, the driving path including straight road driving or curve driving, determining a course angle h2 from the vehicle to the far vehicle and a course angle h3 of the far vehicle relative to the front of the vehicle based on the longitude and latitude information of the vehicle and the far vehicle and the course angle h1 of the vehicle, so as to further judge the position relationship between the vehicle and the far vehicle, based on the driving path, determining a front vehicle which is in the same lane as the vehicle in the far vehicles, and based on the driving path, determining the collision risk and conducting early warning by comparing whether the distance between the front vehicle and the vehicle is smaller than or equal to the minimum safety distance s or not.

Description

technical field [0001] The invention relates to the application field based on the Internet of Things, in particular to a forward collision avoidance method and system based on vehicle-vehicle communication. Background technique [0002] Every year 1.24 million people die in traffic accidents around the world, 91% of which occur in low-income and middle-income countries. my country is also one of the countries most seriously injured by road traffic safety in the world. With the rapid development of my country's transportation industry, the penetration rate of automobiles has increased year by year. While the widespread use of automobiles has brought convenience to people's lives, the frequency of traffic accidents has also increased year by year. Our country attaches great importance to traffic safety issues. Over the years, our government has invested a lot of manpower, material and financial resources in traffic safety legislation, road safety infrastructure construction, ...
