Embodiment Construction

[0087] The present invention is described in detail below in conjunction with accompanying drawing:

[0088] The purpose of the present invention is to overcome the problem that the prior art cannot accurately judge the driver's fatigue level and effectively alleviate the driver's fatigue. It can judge the fatigue level of the driver, and automatically play masking sounds to relieve fatigue when the fatigue level is mild, and wake up the driver when the fatigue level is severe. The present invention adopts the severe fatigue warning mode combined with sudden silence and vibration, which can more effectively wake up the driver in the severe fatigue level, and improves the driving safety. At the same time, the vibration crescendo is adopted to prevent the driver from being in danger due to sudden excessive external stimulation. The present invention introduces a set of system parameter testing methods, which can set targeted parameter thresholds according to different driving h...

Abstract

The invention discloses a car driver fatigue alleviating and waking system and method based on a masking effect. The system includes a fatigue detection module, a masking sound memory module, a masking sound play and severe-fatigue waking module and an automatic control module; the method includes a system parameter test method and a fatigue grade judgment method, wherein the system parameter test method includes the steps of testing lanes and setting test status, and the fatigue grade judgment method includes the steps of using a single-chip microcomputer to conduct a comprehensive analysis by combining a real-time speed according to the weight of each set sensor test item, comparing a set threshold value through the system parameter test method to determine the current fatigue grade of a driver, and controlling the play of a masking sound for severe fatigue waking. The system can automatically play the masking sound to alleviate mild fatigue or give a severe fatigue warning according to the driver's fatigue grade. The method can set the parameters of the driver individually to make the fatigue grade more accurate.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a system and method for alleviating fatigue and waking up a car driver based on a masking effect. Background technique [0002] With the rapid development of the transportation industry, traffic accidents have become a major problem in our country. According to statistics, traffic accidents caused by driver fatigue account for a large proportion. At present, the existing fatigue driving detection methods are divided into active monitoring and passive monitoring, which are judged by detecting the driver's body movements or physiological changes. These monitoring methods have the disadvantages of being difficult to quantify the fatigue level, unable to effectively personalize different drivers, being greatly affected by the working environment, and unable to effectively alleviate the driver's fatigue. At present, most of the existing fatigue driving prompts are voice prom...
