Vehicle-mounted real-time intelligent fatigue monitoring and auxiliary device

Abstract

The invention provides a vehicle-mounted real-time intelligent fatigue monitoring and auxiliary device and belongs to the technical field of automobile safety. The device comprises an individuation fatigue base line adjusting module for user base line entering or updating, an imaging collection module for detecting driver fatigue states, a fatigue parameterization module for parameterizing the driver states, a fatigue grading and instruction generating module for performing grading on the driver fatigue states and generating interference instructions according to fatigue grades, a control module for receiving the interference instructions and an execution module for performing interference instruction motions under the control of the control module, wherein the individuation fatigue base line adjusting module, the imaging collection module, the fatigue parameterization module, the fatigue grading and instruction generating module, the control module and the execution module are connected in sequence. The vehicle-mounted real-time intelligent fatigue monitoring and auxiliary device allows individualized setting and adjustment on users' fatigue base lines, the driver fatigue states are detected and graded, different interference behaviors are controlled according to different fatigue grades, the accident rate can be effectively reduced, and user acceptability is improved simultaneously.

Description

technical field [0001] The invention belongs to the technical field of automobile safety and relates to a driver fatigue monitoring and assisting device, in particular to an intelligent device which monitors the driver's fatigue degree in real time with personalized standards and performs different auxiliary operations according to different fatigue degrees. Background technique [0002] Fatigue driving is one of the main causes of traffic accidents. The resulting traffic accidents account for 22.9% to 30% of the total traffic accidents. Fatigue driving ranks first among the causes of fatal traffic accidents. Therefore, reducing fatigue driving can reduce public property and personal property damage. The vehicle-mounted device is widely embedded in the vehicle due to its small size and convenient use, and has been used in fatigue alarms at present. [0003] The Chinese invention patent "Driver Fatigue Detection Method and Device" published in 2005 with the publication numbe...

Problems solved by technology

[0007] The above two patents detect the fatigue level from two aspects respectively, and each has certain advantages in different external environments. However, since each person’s situation will be different, if they are monitored according to popular standard data, it will inevitably increase. The original existing error, when the error reaches a certain limit, directly leads to wrong judgment, so it is very important to construct accurate personalized reference data. On the other hand, the above patents only divide the fatigue degree into yes and no, which is too simple. It does not take into account the use of some auxiliary measures to improve user acceptance when the driver is not very tired
