Self-protection method and system for vehicle rear-end avoidance early warning and vehicle

Abstract

The invention provides a self-protection method and a self-protection system for vehicle rear-end avoidance early warning and a vehicle and belongs to the field of intelligent vehicles. The method comprises the following steps: acquiring driving parameters of a sample vehicle, as well as vehicle information positioned in the front and rear driving directions of the sample vehicle; determining front-direction and rear-direction collision avoidance early warning time according to the driving parameters of the sample vehicle; generating driving mode conversion information from a result obtained by comparing the collision avoidance early warning time with a preset threshold, and displaying the driving mode conversion information on a liquid crystal screen of the sample vehicle; generating a speed change instruction for controlling the vehicle by combining the rear-direction collision avoidance early warning time with the front-direction collision avoidance early warning time. The driving parameters of the sample vehicle are acquired, the rear-direction and front-direction collision avoidance early warning time is calculated and acquired, the acceleration value is further determined according to the two pieces of collision avoidance early warning time, and different acceleration, deceleration or line change or lane change manners and other treatment manners are further selected according to the acceleration value, so that the incidence rate of rear-direction rear-end traffic accidents is reduced, driving fatigue of a driver is alleviated, and the driving safety is improved.

Description

technical field [0001] The invention belongs to the field of smart cars, and in particular relates to a self-protection method, system and vehicle for anti-rear collision warning of vehicles. Background technique [0002] In recent years, with the rapid development of the automobile industry and the reduction of car purchase costs, cars have become the means of transportation for most people. Although automobiles have greatly facilitated the production and life of human beings, they have also brought many problems to human beings, such as various road traffic accidents, road congestion, environmental pollution and a series of problems. Among them, road traffic accidents have become a serious social problem, which has brought huge losses to the society, the country, and families, and is also one of the reasons that directly cause the abnormal death of most human beings. one of the important reasons. [0003] At present, many research institutes and automobile companies have...

Problems solved by technology

[0003] At present, many research institutes and automobile companies have researched and developed the anti-rear collision warning system for automobiles, but most of the research results are aimed at the anti-rear collision early warning system in the driving direction of the vehicle. This anti-rear collision early warning system is also It only calculates the anti-collision warning parameters such as the safe driving distance between the vehicle in front and the vehicle in front, and does not consider whether there is a rear-end collision risk between the vehicle behind and the vehicle in front. Although the accident rate of rear-end collision with the vehicle in front is reduced, the driving safety behind the vehicle cannot be predicted
