Fatigue driving detection method and anti-fatigue driving auxiliary device

Abstract

The invention provides a fatigue driving detection method and an anti-fatigue driving auxiliary device. The method comprises the following steps: collecting road video information during the driving of a vehicle to calculate line pressing frequency information of wheels; and comparing the line pressing frequency information, road type information, steering wheel operating data, throttle control data, current driving duration and season information with a pre-stored anti-fatigue driving model to judge whether a driver is in a fatigue driving state or not. The device comprises a data collecting component for collecting road video information and vehicle state, a program logic component for processing data collected by the data collecting component, and a fatigue driving judging component for comparing and judging; and a pre-warning respond component is used for voice alarming and deceleration and brake stop operation when the driver is in the fatigue driving state. The invention has the advantages of instantaneity, accuracy and wide adaptability.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a fatigue driving detection method and an anti-fatigue driving auxiliary device. Background technique [0002] With the increasing number of vehicles, driving accidents are increasing year by year, and fatigue driving is an important factor causing road safety accidents. How to quickly and accurately detect the driver's fatigue status, give reminders, and take compulsory measures to reduce the speed of the vehicle when it is serious, has great significance for reducing accidents caused by fatigue driving. [0003] Most of the existing fatigue driving detections are aimed at the detection of driver’s facial and eye features and abnormal behaviors, combined with machine learning methods to make judgments, because such methods of fatigue driving detection need to collect a large amount of data, and different drivers have different There is a large deviation in this driving ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a fatigue driving detection method that uses the vehicle-mounted camera to detect the frequency information of the wheel pressure line and combines it with the vehicle position estimation, so as to solve the real-time performance of the existing fatigue driving detection method due to the individual differences of drivers.
