The characteristics of fatigue driving are as follows:

Driving fatigue refers to the phenomenon that the driver’s psychological and physiological functions are out of balance after driving continuously for a long time, and the driving skills are decreased objectively. Driving fatigue can affect the driver’s attention, feeling, perception, thinking, judgment, will, decision and movement, which is one of the important causes of traffic accidents.

1. Body fatigue

When driving, the driver’s pulse and heart rate increase. This is mainly due to the acceleration of exercise and the increase of oxygen consumption in muscle activity.
If the posture is not correct or the fixed posture lasts too long, although the force is not big, fatigue will also appear. This is due to muscle activity, causing vasoconstriction and relaxation, so that the driver moved fatigue

2. Mental fatigue

Simple and rigid driving operation can inhibit the normal state of blood pressure, breathing and heart rhythm, which leads to insufficient blood supply to the brain and mental fatigue. The complex and changeable traffic environment makes the driver always in a state of tension, and even in a state of extreme tension when encountering dangerous situations. Excessive tension and continuous tension will inevitably lead to mental fatigue

3. Spinal fatigue

The driver will have backache and backache, which is mainly due to the spinal fatigue reaction caused by inappropriate seat or incorrect sitting posture. Over time, the intervertebral disc will be damaged, which will also cause lumbar disease.

4. Eye fatigue

When the driver continuously drives for a long time or does not get enough sleep, eye muscle relaxation, decreased eye rotation, frequent blinking, even tremor and visual ghosting often occur, which is the reaction of eye fatigue.

5. Outward signs of driving fatigue

Slight fatigue: mental fatigue, frequent yawning; eye fatigue, heavy eyelids; muscle fatigue; untimely shift, inaccurate.
Moderate fatigue: eyes astringent, pain; drowsiness, wandering; body fever; spinal fatigue, backache, stiff action.
Severe fatigue: drowsiness, blurred consciousness, unconsciousness, drowsiness, and sometimes the feeling of suddenly waking up; rapid heartbeat; double shadow in visual image; shivering and cold sweat; subconscious operation behavior.

In recent years, the number one “killer” of traffic safety is fatigue driving, which has caused a lot of serious traffic accidents. A traffic accident broke many families. In order to solve the hidden danger of fatigue driving, Leisure Auto technology adopts the unique face recognition technology to launch the intelligent fatigue driving warning system.

1、 Working principle of fatigue driving early warning system

Fatigue driving warning system is based on the physiological image response of the driver, which consists of ECU and camera modules. The driver’s fatigue state is inferred by the driver’s facial features, eye signals, head movement, etc., and alarm and corresponding measures are provided. Provide more intelligent security to drivers. The small camera is installed in front of the driver in the cab, and the driver can be reminded by local voice and sound and light warning mode in real time, and the background management personnel can receive the driver fatigue alarm information.

2、 The function of fatigue driving early warning system

Fatigue warning: judge the fatigue driving duration according to the driving time and the current driver status;

Driver face recognition function: can accurately judge closed and open eyes;

Attention distracted detection and early warning, looking left and right, not looking forward to the situation judgment;

It can adapt to the complicated lighting conditions in the actual driving environment, and realize 24-hour monitoring, including wearing myopia glasses;

Long driving and night driving reminder;

Remote monitoring and warning function: image upload reminder.

3. System application scenarioDSM application

Fatigue driving warning system is applicable to daytime, night, various climate, various skin color, wearing myopia glasses and various models. This product is suitable for most weather conditions such as day, night and rain and snow, and can be installed on all kinds of private cars and commercial vehicles such as buses, taxis, passenger vehicles, mining vehicles, freight vehicles, dangerous goods transport vehicles, school buses, ballast trucks, and even metros. It’s an extra safety products for fleet management, not only for vehicles and goods on the vehicle, but the more important element: drivers!

1. Is the infrared light harmful to my eyes and body?

No at all, the average light outlet power is less than 0.2W, and mostly died down when spreading in a 30°angle and meter distance, less than 1/10 of indoor nature light, just because the infrared light can’t been seen when mixed with other lights, you don’t aware the existing.

2. I’m worry about too much noisy alarms.

Don’t worry, the device have 4 level sensitivities, the lowest level mainly alarm for the real sleeping, looking around need 5-7 seconds to trigger the alarm, nobody will do it so long when driving on the highway.

3. If I must drive under fatigue status, is this unit useful?

Yes, some trunk drivers always drive under fatigue status, some people used to dozy when driving in on the highway, or if you have sleepless night but must drive today. LS801’s main target is not to detect the fatigue driving, but the instant of dozing off, giving out alarms in that instant to wake you up.

4. Is it difficult to install?

No, it’s very easy, just stick the main unit in front of the driver, and connect power from cigarette socket, no need any engineer or garage!

5. Will it influent my sight?

No, it’s much smaller than a GPS navigator, and no need you to stare at it, just leave it alone after you have adjusted the angle toward your eyes.

6. What’s your advantage comparing to the other driver fatigue alarm system?

There are 3 kinds of fatigue alarm system on the market: Nap zipper, it judges the fatigue status only from the driver’s nod, but some people don’t nod at all when sleeping, and some people used to nod when taking or singing, the accuracy is very low. Lane Departure Warning system, this system have restrict, if there is no line on the road, it’s no use at all, as we know, there is too much road without any line, or only 1 line in the middle, or the line is broken, all of those will influent the accuracy. Collision Prevention, this kind of products always use image, millimeter waves or laser light to calculate distance between your car and front/back car, but image will be influent by light and raining weather, millimeter is too expensive and huge size, laser light will kill 10,000 pieces of your retina cells if scan 30 times/second.   And all of those products are detecting the behavior of fatigue, but some of drivers will keep driving in straight line and same speed after dozed off 10-20 seconds, it’s very dangerous if there is any overtake, obstacles or passengers. Our product LS801, waking up the driver in the doze off instant, much more efficient than those products.

7. Why the device don’t alarm when I closed my eyes?

It have 3 reasons: First, the device need to recognize the driver’s face in the first 10-20 seconds after powered on, it can’t be triggered in this period. Second, the device is smart, if you have big body movement, or speaking, or turned you head, it will recognize that you are in sober status and wouldn’t give our alarms until 5-7 seconds. Third, you are too near, far, low or high, means you are not in center of the camera’s shot area, please adjust your seat and the direction ball. On the other hand, if you have no movement, speaking, driving in a high speak, and your eyelid is lower and lower, it will give out alarms in 2 seconds as long as your eye closed or pupil can’t be detected.

8. Why the device not as sensitive as the beginning?

The lens is dirty, please use cotton bud to clear it, if necessary, use some alcohol.

9. It just don’t work at all, what’s the problem?

The system require 12V power and instant electric current 400-500mA, please check your power supply, if the voltage is low, or electric current is not enough, the device may have green light on, but not alarm.

1、 Fatigue driving is caused in this way.

There are many factors causing fatigue driving. Driver’s fatigue is mainly the fatigue of nerves and sensory organs, as well as limb fatigue caused by long-time keeping a fixed posture and poor blood circulation.

2、 Fatigue driving is very easy to cause traffic accidents.

Driving fatigue refers to the imbalance of physiological and psychological functions of drivers after driving continuously for a long time, and the decline of driving skills objectively. The driver’s sleep quality is poor or insufficient, driving for a long time, prone to fatigue. Driving fatigue will affect the driver’s attention, feeling, perception, thinking, judgment, will, decision and movement.

3、 Fatigue can be divided into physical fatigue and mental fatigue.

From the point of fatigue recovery time, it can be divided into acute fatigue, chronic fatigue and cumulative fatigue. Acute fatigue is temporary fatigue caused by daily work. After a short rest, fatigue will disappear. Normal driving fatigue belongs to this kind of fatigue. Chronic fatigue is caused by long-term fatigue, which makes the quality of labor decline and affects physical and mental health.

4、 Driving in summer is easy to make you fatigue.

Driving in hot weather in summer or in the environment of overheating in the cab, with high temperature and poor air circulation, drivers are easy to get tired, often feel sleepy, their sight gradually becomes blurred and their thinking becomes dull. Especially driving in the afternoon, they are easy to doze off, and even have the phenomenon that drivers lose their memory in an instant and drive reluctantly It can lead to traffic accidents.

5、 The highway road surface is wide。

there are few fixed reference objects, and the speed of traffic flow is high; there are no traffic signal control and road intersection, and there is no pedestrian, non motor vehicle and other low-speed motor vehicle interference, all vehicles maintain a high speed, and each road moves orderly. When driving on the highway, the driver’s energy is always in a state of high tension, the physical consumption increases, and he will unconsciously increase the speed, and even lose the awareness of braking and deceleration.

6、 High speed driving is easy to lead to fatigue driving.

When driving, with the increase of speed or continuous high-speed driving, drivers will have different degrees of driving fatigue. When driving at high speed, the driver’s attention is very focused and always in a state of high mental tension. With the continuous improvement of speed and the extension of driving time, the driver will gradually feel tired.

7、 The harm of fatigue driving is that the judgment ability of drivers is decreased.

The reaction is slow and the operation error is increased when they are tired. When the driver is in slight fatigue, the gear shifting is not timely and accurate; when the driver is in moderate fatigue, the operation is sluggish, and sometimes he even forgets to operate; when the driver is in severe fatigue, he will often subconsciously operate or sleep for a short time, and when it is serious, he will lose the ability to control the vehicle.
