The causes of fatigue driving are

Fatigue driving is very dangerous and can easily lead to traffic accidents. There are many reasons for fatigue driving, such as driving for too long, poor sleep quality, and lack of rest. In addition, the environment inside the car is also a factor. For example, if only one person is driving, the air quality is poor, or the temperature is too high, etc., these are all important reasons for fatigue driving.

The causes of fatigue driving are

1. Living environment: the place of residence is too far from the place of work; there are too many housework or the couple is not harmonious; the mental burden is heavy; the social circle is too broad and the time spent on cultural and entertainment activities is too long. 2. Sleep quality: Going to bed too late and getting too little sleep; poor sleep quality; a noisy sleeping environment cannot guarantee sleep quality. 3. In-vehicle environment: poor air quality and poor ventilation; temperature that is too high or too low; severe noise and vibration; improper seat adjustment; tense relationships with fellow passengers. 4. External environment: driving in the afternoon, evening, early morning, and late night; poor road conditions; good road conditions but simple conditions; driving in windy, rainy, foggy, or snowy weather; poor traffic environment or congested traffic conditions.

Domestic products for preventing driving fatigue:

1. Drivers are usually reluctant to wear an ear alarm. The function is very simple. It will sound an alarm when the driver lowers his head. First of all, if a driver dozes off, he may not lower his head. By the time the driver lowers his head, it may be too late to sound the alarm. 2. Drinking coffee or spraying stimulants into your mouth will only have a short-term effect, and once the time is over, you will feel more tired. If you use it continuously for a month, it will no longer have any effect on you. 3. Watch type and glasses type. The watch type uses the pulse beat to estimate whether a person is tired. It has no authoritative scientific basis and cannot solve the problem of falling asleep suddenly. The glasses type forces people to wear a pair of thick glasses to judge the blinking frequency. Basically, many people are not adapted to it. In fact, there is no direct relationship between blinking frequency and fatigue. 4. Touch steering wheel. Some sensors are installed on the steering wheel to sense whether the driver is holding the steering wheel. This has no direct relationship with fatigue. It is difficult to take things from some people who fall asleep. When the alarm is triggered after the person relaxes, the car is probably dead. It is really far-fetched. In addition, installing sensors will make steering wheel operation inconvenient. 5. The lane departure warning system is technically easy to implement, but it is not suitable for China's road conditions, and there will be false alarms when overtaking, being overtaken, merging lanes, and crossing the lane. Once there are too many false alarms, people will no longer be sensitive when it is time to sound the alarm at a critical moment.
