Abstract

The invention provides a fatigue driving detection method and apparatus. The method includes the following steps: acquiring the rotation speed of a steering wheel within a current preset period and recording the time point of the acquisition; based on all the rotation speeds of the steering wheel and the time points of the acquisition in the current preset period, generating a steering wheel rotation speed feature curve; based on the steering wheel rotation speed feature curve, a first rotation speed threshold which is intended for representing the lowest rotation speed of the steering wheel under the circumstances of normal operation, and a second rotation speed threshold which is intended for representing the lowest rotation speed of the steering wheel under the circumstances of abnormaloperation, determining the operation state of a vehicle in the current preset period; invoking the operation state of the vehicle within a previous preset period; and if the operation state of the vehicle within a previous preset period is a non-operation state, and the operation state of the vehicle within the current preset period is an abnormal operation state, determining that a driver is ata fatigue driving state. According to the invention, the method can accurately detect fatigue driving without influencing a driver's normal driving, and ensures detection accuracy and driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, and more specifically, relates to a fatigue driving detection method and device. Background technique [0002] In recent years, with the rapid increase of car ownership and motor vehicle drivers, road traffic safety has become a social focus, and fatigue driving is the main cause of traffic accidents. [0003] At present, the detection of fatigue driving mainly includes facial feature detection and physiological index detection. If facial features are used, such as eye movements, facial expressions, etc., it is necessary to collect the driver’s facial image. However, due to the limitations of the driver’s head position and the light in the cab, the collected facial image is likely to be unclear. Affect the accuracy of subsequent detection; and if using physiological indicators, such as ECG data, respiratory rate, etc., the driver needs to wear relevant equipment, which may inte...
