Problems solved by technology

Although the present invention can give an alarm to fatigue driving by calculating the driving time, but only by calculating the driving time to judge whether it is fatigue driving, the detection accuracy is low, and for drivers of different ages, the fatigue driving time is different, and The degree of fatigue when driving at different time periods is also different

Embodiment Construction

[0020] The following are specific examples of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these examples.

[0021] The driver fatigue monitoring method based on offline data matching includes the following steps:

[0022] Step 1. Obtain the initial matching fatigue index: monitor the lane line information in real time through the camera installed in front of the vehicle and send the lane line information to the microprocessor for processing and storage; Carry out real-time monitoring and send the steering wheel angle information to the microprocessor for processing and storage; then compare the processed lane line information and steering wheel angle information with the pre-stored basic fatigue index through the microprocessor to obtain the initial matching fatigue index;

[0023]Step 2. Correct the initial matching fatigue index: analyze and process the collected driver’s identity inf...

Abstract

The invention provides a driver fatigue monitoring method based on off-line data matching, and belongs to the technical field of automobiles. The method solves the problem of inaccurate fatigue coefficient monitoring in the prior art. The driver fatigue monitoring method based on the off-line data matching comprises the following steps: the step I, obtaining an initial matching fatigue index that currently acquired lane line information and currently acquired steering wheel angle information go through analysis processing and then are compared with a pre-stored basic fatigue index, and then the initial matching fatigue index is obtained; the step II, correcting the initial matching fatigue index that the initial matching fatigue index is corrected according to a driver correction coefficient and driving time correction coefficient, and then a matching fatigue index is obtained; and the step III, obtaining a driver fatigue coefficient that the matching fatigue index is corrected according to an actual fatigue coefficient to obtain the driver fatigue coefficient, and a corresponding prompt is given according to the obtained driver fatigue coefficient. Accuracy of driver fatigue monitoring can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a driver fatigue monitoring method based on offline data matching. Background technique [0002] Fatigue driving refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. For example, when the driver is slightly fatigued, the gear shift will not be timely and accurate; when the driver is moderately fatigued, the operation action will be sluggish, and sometimes even forget to operate; Temporary sleep phenomenon, when serious, will lose the ability to control the vehicle. If the driver is still barely driving the vehicle after fatigue, it may cause traffic accidents. [0003] For the problem of fatigue driving, some existing vehicles are equipped with driver fatigue warning system, which can monitor the driver's state, and when the driver ...
