V2X system-based collision pre-warning method and device and storage medium

Abstract

The invention discloses a V2X system-based collision pre-warning method. The method comprises the steps of establishing a rectangular plane coordinate system by taking the centroid of a main vehicle as an original point, taking the driving direction of the main vehicle as an X axis and taking the left-side direction of the main vehicle as a Y axis after the main vehicle is started; enabling the main vehicle to obtain the driving state of a far vehicle and adding the far vehicle into the rectangular plane coordinate system so as to establish a collision model for the main vehicle and the far vehicle; carrying out calculation to determine whether the main vehicle and the far vehicle satisfy a collision pre-warning condition or not; if both the vehicles satisfy the collision pre-warning condition, giving collision pre-warning; and otherwise, not carrying out reminding. The invention further discloses a device for realizing the method and a storage medium, in which a program for realizingthe method is stored. According to the method, the device and the storage medium, the effects of enlarging the vehicle collision pre-warning range, pre-warning the vehicles which ignore the obstaclesand prompting the collision threaten sources are achieved.

Description

technical field [0001] The present invention relates to the field of automobile driving assistance methods and devices, in particular to a collision warning method, device and computer-readable storage medium based on a V2X system. Background technique [0002] The Internet of Vehicles (V2X system in a broad sense) is the use of a new generation of information and communication technology to realize all-round network connections in the car, between cars and people, between cars and cars, between cars and roads, and between cars and service platforms, and to improve the level of car intelligence and build a car life. The new business ecology improves traffic efficiency and provides users with intelligent, comfortable, safe, energy-saving and efficient comprehensive services. The short-distance communication technology of the V2X system can realize multi-vehicle cooperative mutual perception. Through the V2X system, the sensing range of the car can be extended to the range tha...

AI Technical Summary

Problems solved by technology

[0003] The current driving assistance collision warning mainly uses the sensor of the car to perceive the surrounding environment of the car; the use of the car sensor for collision warning has the following defects: 1. The sensing distance is short, and the distance of the general car sensor is only tens of meters away Realize the emergency anti-collision warning of short-distance vehicles, and the warning effect is greatly reduced; 2. It is impossible to pass through obstacles. If there are obstacles such as buildings and cliffs next to the road, the car sensor will fail, and the collision warning function cannot be used; 3. It cannot be given Collision direction, if encountering a collision threat, the car can only provide an alarm sound, but cannot provide the direction of the collision threat, which is not practical enough
