Problems solved by technology

However, as mentioned above, the occasions of driving with low vigilance are varied, so that these inventions may not be effective in practical application, especially for preoccupied drivers and novice drivers who lack driving experience (even if the driver’s psychology, Physiological state is normal)
The search found that there is still a lack of effective integration solutions and inventions for detection and early warning of low-vigilance driving

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] What the present invention discloses is a low-alertness driving early warning method, by detecting the action frequency of the driver's observation of the left and right exterior mirrors and the upper interior mirror, and comparing it with the set value, it is judged that the driver is driving. When the driver is in a state of low alertness, it will give an early warning or take further measures such as speed limit and double flashing on the driving state.

[0027] Such as image 3 As shown, the specific steps of the low vigilance driving warning method are:

[0028] Step 1, collecting the driver's head image;

[0029] Step 2: Process the image to determine whether the driver is observing the left and right exterior mirrors and the upper interior mirror, and obtain the viewing frequency;

[0030] Step 3, compare the obtained...

Abstract

The invention discloses a low-alertness driving early warning method and device. According to the low-alertness driving early warning method and device, the motion frequency that a driver observes a left backup view mirror outside a car, a right backup view mirror outside the car and a rearview mirror at the upper portion inside the car is detected through a camera and a controller and is compared with a set value, the alertness of the driver in the driving process is judged, and when the driver is in a low-alertness state, the driver is warned or the driving state is further dealt with. The low-alertness driving early warning method and device solve the problem of low-alertness or alertness-free driving caused by fatigue, doze, drunk driving, mind wondering, inattention, insufficient driving experience, bad driving habits and the like of the driver, is simpler and more reliable in detection principle compared with an existing fatigue early warning device and a drinking early warning device, and is more general in applicability on application occasions.

Description

technical field [0001] The present invention relates to vehicle active safety technology and its application field, and more specifically, relates to a vehicle-mounted device and method capable of monitoring the driver's driving alertness state in real time and realizing automatic prompting or warning when the driver is judged to be in a low-alertness driving state. Background technique [0002] The driver’s alertness during driving refers to the driver’s ability to actively observe the surrounding traffic environment and adjust the corresponding driving behavior during driving. The most direct manifestation is that the driver frequently observes the left and right outside mirrors and the interior rear view mirror to understand the behavior of surrounding traffic conditions. Generally speaking, the higher the driving alertness, the safer the driving. However, low-alertness driving conditions widely exist in reality, especially when the driver is in a state of fatigue, drows...
