Method and device for judging fatigue driving

Abstract

The invention discloses a method and device for judging fatigue driving. A driving information record generated by a vehicle OBD (On-Board Diagnostics) device when a vehicle is driven serves as a resource parameter; a driver driving behaviour logically manually analyzed serves as a comparison parameter; a processing unit takes a comparison parameter as a basis to carry out data judgement and accumulation on the resource parameter; and when the accumulated resource parameter reaches the set standard, an automobile driver is judged to be in the fatigue driving state.

Description

technical field [0001] The present invention relates to a method and device for judging fatigue driving, in particular to a method of using the standard vehicle perception signal captured by the existing OBD device of the car as a parameter, and performing data analysis and interpretation through a processing unit, so as to judge whether the driver has fatigue or not. Approaches to Drowsy Driving Situations. Background technique [0002] According to the data on the causes of road traffic accidents in Taiwan, China in 2005, 82% of the traffic accidents were caused by the driver's behavior factors, which mainly include improper driving (including drunk driving) and fatigue driving. Among them, fatigue driving is most likely to be neglected by the driver, so someone has released an instrument for judging whether the driver is in fatigue driving; please refer to China Taiwan Patent Application No. 093102220 "a kind of driving that prevents the driver from continuing to drive af...

Problems solved by technology

[0003] In addition to detecting the number of eye blinks of the driver as a way to judge driving fatigue, some people use the detector to sense the pupil of the driver's eyeballs as a way to judge driving fatigue. As the basis for judging fatigue driving, it is in principle based on the physiological state of the human body. This method is difficult to make accurate judgments due to individual physiological differences (because the number of eye blinks and pupil dilation varies from person to person) , and this kind of creation must constantly detect the human body through detectors, so it has problems such as low cost-effectiveness

[0004] In view of the shortcomings of the fatigue driving judgment device that uses human physiological information as the detection device in the prior art, the author proposes a method to extract OBD data as a judgment fatigue driving method, which can effectively overcome the inaccurate judgment and equipment Disadvantages such as high cost;
