Embodiment Construction

[0023] The implementation steps of a fatigue driving detection method based on multi-information fusion are as follows:

[0024] The first step is to build a fatigue driving detection system

[0025] The composition of the fatigue driving detection system includes a signal acquisition module, a signal processing module and an alarm module.

[0026] The main function of the signal acquisition module is to collect signals that can reflect the driver's fatigue. Signals that reflect the driver's fatigue include respiratory signals, pulse signals, body temperature signals, steering wheel pressure signals, and steering wheel angle signals.

[0027] The signals collected by the signal collection module include respiratory signals, pulse signals, body temperature signals, pressure signals of the steering wheel and steering wheel angle signals related to the driver's fatigue state.

[0028] The extraction of the respiratory signal uses a pole-changing capacitive sensor to detect chan...

Abstract

The invention discloses a multi-information fusion based fatigue driving detecting method. A fatigue driving detecting system used in the method comprises a signal collection module, a signal processing module and an alarming module, wherein the signal collection module collects signals relative to fatigue, the signal processing module quantizes fatigue levels of a driver, extracts feature parameters which can reflect fatigue states of the driver, performs fuzzy clustering on the feature parameters, and real-timely detects the fatigue states of the driver, and the alarming module timely performs alarming when the driver is determined to be in fatigue driving. The multi-information fusion based fatigue driving detecting method consists of a plurality of steps of signal collection, fatigue level quantization and signal processing, feature parameter extraction, and fatigue determination and alarming. The fatigue driving detecting system is vehicle-mounted, has non-compulsivity, and is capable of performing real-time determination and high in determination accuracy.

Description

technical field [0001] The invention relates to a method for detecting fatigue driving of a motor vehicle driver, in particular to a method for detecting fatigue driving based on multi-information fusion. Background technique [0002] Due to frequent traffic accidents caused by fatigue driving, it has brought great harm to people's lives and property. Therefore, the research and development of fatigue driving early warning system is of great significance. At present, there are many studies on fatigue driving detection technology. The main methods include using the driver's EEG and ECG signals to determine the fatigue status, using video and image processing technology, and some products detect the driver's body posture. Judging fatigue, these studies have achieved certain results, but there are still the following deficiencies: the equipment for collecting EEG and ECG signals is very complicated, not suitable for vehicles, and electrodes need to be pasted on the driver's bod...
