Fatigue driving prevention system and method

Abstract

The invention discloses a fatigue driving prevention system. The system comprises a vehicle-mounted computer, a face acquisition camera, an electronic control unit (ECU), a voice module, a wireless module and a customer service terminal, and is characterized in that the face acquisition camera is connected with the vehicle-mounted computer, and the ECU is connected with the vehicle-mounted computer; the voice module is connected with the vehicle-mounted computer, and the vehicle-mounted computer is connected with the customer service terminal through the wireless module. The head and the faceinformation of a driver are recognized and judged, and can be directly confirmed through voice responses, and finally a plurality of reminding modes are set to supervise the driver. Fatigue driving judgment is performed only on the basis of the physiological characteristic, namely the facial expression, of the driver, so that the process is simplified; the state of the driver is judged through integral information of the eyes and the head, and the voice response link is added, so that the accuracy of judging the driving state of the driver is fully guaranteed; a plurality of urging modes are set for the driver to select, so that the supervision efficiency of the driver is improved, and the driving safety of a driver is guaranteed.

Description

technical field [0001] The invention relates to the field of automobile intelligent driving, in particular to an anti-fatigue driving system and method. Background technique [0002] With the development of our country's economy, the number of cars has increased dramatically, and correspondingly, traffic safety issues have gradually attracted attention. According to statistics, fatigue driving has become an important factor affecting road safety. [0003] Some existing fatigue driving identification methods at home and abroad, such as some vehicle monitoring devices use special equipment to accurately measure head movement, pupil diameter changes and blinking frequency, or use vision and steering wheel manipulation sensors to use artificial intelligence to judge the driver's awake state. These methods and devices have not been widely used due to reasons such as being too complicated and expensive. For the fatigue driving prevention method utilizing background video real-ti...

AI Technical Summary

Problems solved by technology

These methods and equipment have been unable to be widely used due to reasons such as being too complicated and expensive.

For the method of fatigue driving prevention using background video real-time monitoring, because the video needs to be transmitted through wireless channels, the usage cost is relatively high

And all there is certain false alarm probability in above-mentioned two kinds of fatigue driving recognition methods, therefore be necessary to invent a kind of simple, effective, method and device for identifying fatigue driving that false alarm probability is lower, remind driver to drive safely
