Driving safety behavior analysis method, driving safety early-warning method, driving safety behavior analysis device and driving safety early-warning device

Abstract

An embodiment of the invention relates to a driving safety early-warning method which is used for analyzing driving behavior of a driven vehicle. The driving safety early-warning method comprises the steps of acquiring driving information of the driven vehicle, driving road identification information and driving environment information at the periphery of the driven vehicle; performing analysis according to the driving information of the driven vehicle, the driving road identification information and the driving environment information at the periphery of the driven vehicle, thereby obtaining the driving condition result of the driven vehicle and the driving environment condition result at the periphery of the driven vehicle, analyzing a lane changing driving behavior according to the driving condition result of the driven vehicle and / or the driving environment condition result at the periphery of the driven vehicle, and outputting the analyzed result. According to the driving safety early-warning method, the driving information of the driven vehicle, the driving road identification information and the driving environment information at the periphery of the driven vehicle are comprehensively considered in early warning in the lane changing process, so that a more accurate lane changing analysis result can be obtained, and early-warning information can be accurately transmitted according to the lane changing analysis result. The invention further provides a driving safety behavior analysis method, a driving safety behavior analysis device and a driving safety early-warning device.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a driving safety behavior analysis method, an early warning method and a device thereof. Background technique [0002] With the development of economy and the improvement of people's living standards, the number of cars is increasing, and the complexity of roads is becoming more and more serious. Driving safety has become an important issue. For example, changing lanes is a very common driving operation in the driving process, but it is also a major factor causing traffic accidents. How to change lanes effectively and safely has become a problem that needs to be solved urgently. Therefore, in the prior art, there is a method of prompting whether to change lanes safely by analyzing whether there is a turning signal when changing lanes. It is obvious that it is too simple to judge whether it is safe to change lanes only by analyzing whether the turning lights are turned on, and it ...

AI Technical Summary

Problems solved by technology

[0003] see figure 1 , figure 1 In order to simulate the realistic road conditions, it is relatively safe for car A to change lanes to the right, but it cannot change lanes to the left because there are double yellow lines 11 on the left, and it is unsafe for car C to change lanes to the right. When turning on the turn signal, you need to keep a safe distance from car D before changing lanes to the right. In addition, car C cannot change lanes to the left, and the left side is the solid line 12

Obviously, the existing method of judging whether the driving behavior of changing lanes is a safe behavior only by analyzing whether the turn signal is turned on or not, basically does not work in the face of such real road conditions
