Problems solved by technology

At present, a variety of fatigue early warning devices have been developed at home and abroad, mainly through physiological detection, face recognition, and wearing induction bracelets or helmets to complete fatigue state detection. The accuracy and precision are not high, and it is inconvenient to use and wear.
Most of the fatigue warning equipment can only realize the reminder function, and cannot intervene on the fatigue driver, which will also cause traffic accidents
[0003] At present, there are many deficiencies in the intervention devices for fatigued drivers, the most important of which is that they cannot meet personal characteristics, resulting in poor intervention effects of the intervention devices

Abstract

The invention discloses a fatigue driving early warning intervention system which comprises a self-adaptive data acquisition module, an ECU data processing module, an ECU control module, a power module, a fault self-diagnosis module, an automatic early warning device, a vibration intervention motor and an automatic braking system. According to the system, the influence of individual difference of drivers on fatigue driving detection and recognition can be well eliminated, the precision is high, and the accuracy is good. Besides, according to different fatigue driving degrees, the automatic early warning device and the vibration intervention motor can conduct voice reminding and vibration intervention of different levels respectively, and reminding and intervention are stopped after the fatigue driving state is relieved; when the fatigue driver stays at the same steering angle for a long time, the automatic braking system can be directly started, and therefore potential safety hazards caused by fatigue driving are reduced.

Description

technical field [0001] The invention belongs to the technical field of fatigue driving early warning and intervention, in particular to a fatigue driving early warning and intervention system. Background technique [0002] With the development of social economy and the improvement of people's living standards, the number of cars is increasing year by year, and the traffic pressure is increasing. Fatigue driving has become one of the important reasons for traffic accidents. Fatigue driving increases the probability of accidents, so there are more and more researches on fatigue driving. At present, a variety of fatigue early warning devices have been developed at home and abroad, mainly through physiological detection, face recognition, and wearing induction bracelets or helmets to complete fatigue state detection. The accuracy and precision are not high, and it is inconvenient to use and wear. Most of the fatigue early warning equipment can only realize the reminding functio...
