Abstract

The invention relates to the field of automobile driving safety early warning, and in particular relates to a fatigue driving early warning method and system based on a decision algorithm. The fatigue driving early warning method comprises the steps that S1 in a detection period, an information acquisition module acquires driver behavior characteristic information and vehicle driving characteristic information and sets decision influence weight factors of each piece of information; S2 a terminal mainboard calculates a fatigue state value of a driver; and S3 the terminal mainboard compares the fatigue state value with a fatigue comparison value, obtains the attenuation amplitude and generates fatigue early warning. Compared with the prior art, the method has the advantages that through the decision algorithm, the characteristic behaviors of fatigue driving are weighted and analyzed, the fatigue state of the driver can be accurately evaluated, corresponding early warning is made according to the evaluation result, the fatigue driving early warning precision is improved, and meanwhile the traffic hidden danger caused by fatigue driving is reduced.

Description

technical field [0001] The invention relates to the field of automobile driving early warning, in particular to a fatigue driving early warning method and system based on a decision algorithm. Background technique [0002] With the development of social economy and the improvement of people's living standards, cars have begun to enter thousands of households. With the increase of car ownership and the improvement of people's life pressure, the proportion of traffic accidents caused by fatigue driving is also increasing. At present, a variety of fatigue early warning devices have been developed for fatigue driving detection at home and abroad. Fatigue monitoring is mainly completed through physiological detection, face recognition, and wearing induction devices. It is troublesome to wear and the accuracy is not high, and it is prone to false and missed reports. Therefore, Fatigue monitoring devices are not widely available. Contents of the invention [0003] In order to s...
