Fatigue driving detection method based on driving behavior

Abstract

The invention discloses a fatigue driving detecting method based on driving behaviors. The problem that in the prior art, a road curvature factor can affect accuracy of a fatigue driving detecting method based on the driving behaviors is solved. A road alignment classifier and corresponding fatigue mode classifiers are established, road videos of a vehicle and driving behavior information in the process of vehicle travelling are collected in real time, driving behavior characteristic parameters of a driver under different road curvatures (a straight road and a curve road) are respectively extracted, current road alignment is determined according to a result output by the road alignment classifier, the corresponding fatigue mode classifiers are called, and therefore the fatigue state of the driver can be identified. The method achieves accurate detection of fatigue driving in real time.

Description

technical field [0001] The invention relates to a detection method in the technical field of automobile safety, in particular, the invention relates to a fatigue driving detection method based on driving behavior. Background technique [0002] Fatigue driving is one of the main factors causing road traffic accidents. Every year, traffic accidents caused by fatigue driving account for about 20% of the total number of accidents and more than 40% of serious traffic accidents. Therefore, it is necessary to detect the driving state of the driver in real time, and when fatigue occurs, an effective early warning is given to avoid road traffic accidents. [0003] At present, fatigue driving detection methods are mainly divided into detection methods based on subjective evaluation, detection methods based on driver's physiological signal, detection method based on driver's physiological response, detection method based on driving behavior and detection method based on information fus...
