Fatigue driving is a problem that truck drivers can never avoid. The freight logistics industry needs timeliness, and the transportation efficiency also determines the money income. Therefore, driving hard has become the norm of truck drivers.
Article 62 of the regulations for the implementation of the road traffic safety law stipulates that driving a motor vehicle shall not have the following behaviors: driving a motor vehicle continuously for more than 4 hours without stopping for rest or stopping for less than 20 minutes.
However, it is common for truck drivers to drive continuously for more than 10 hours. This is related to their indifferent safety awareness, but it is more due to the constraints of livelihood and transportation time. In order to reduce the harm of fatigue driving to driving safety, I think we should start from two aspects.

Establish safety awareness and improve the income of transportation practitioners
Fatigue driving is a common thing for truck drivers. I believe many old drivers have experienced it when driving until they close their eyes. Although they were shocked at that time, few people can really drive without fatigue after that. The combination of work and rest is more an extravagant hope for truck drivers.
Too much life pressure makes many truck drivers ignore the importance of safety and establish safety awareness. First, we should strengthen the publicity and education of safe driving. Second, we should reduce the burden of truck drivers and improve the income of practitioners in the transportation industry. The combination of the two can fundamentally reduce the current situation of truck drivers’ fatigue driving. I think the imbalance between truck drivers’ income and pay at this stage is the root of the problem of fatigue driving.

Introduction of fatigue driving warning system

Mercedes Benz, Lexus and other manufacturers have long been widely used in the field of household vehicles in terms of fatigue driving reminder function. Its principle is to detect and analyze the driver’s eye state, driving posture, accelerator and brake pedal control, driving track, hand action, etc. through sensors and cameras. When the driver is detected to have fatigue driving tendency, it will vibrate, Buzzer, instrument display reminder icon, etc. to help the driver restore normal mental state and remind the driver to rest.
This function is undoubtedly very helpful for truck drivers. When the driver is sleepy and distracted, although the fatigue driving warning function can not directly take over the control of the vehicle, reminding the driver to pay attention to his mental state is also a great help for many drivers who drive long-distance bicycles, The best of them is LS505 from leisure auto.
At present, domestic truck enterprises have not launched trucks with fatigue driving reminder function, which is subject to both cost and technology, but there is no doubt about the practicability of this function. It is hoped that domestic trucks will be installed with fatigue driving reminder system with high monitoring accuracy as soon as possible.
The fatigue driving reminder system needs the cooperation of software and hardware to improve the prediction accuracy, which requires a lot of experiments and design. In fact, truck enterprises do not need to develop it separately. Many domestic passenger car manufacturers have this technology, and enterprises can seek cooperation. Car enterprises can also work with Internet enterprises to improve the practicability of the fatigue driving reminder system, After all, the power of Internet enterprises at the software logic level is unmatched by traditional automobile enterprises, which improves the R & D efficiency, and the early loading application also improves the product power of trucks.
summary
Safety is more important than money. Traffic accidents caused by fatigue driving account for about 20% of all accidents. Non fatigue driving is equivalent to 20% more safety. I hope you can be more aware of the harm of fatigue driving. I also hope that fatigue driving reminder can be introduced into the truck field faster to add a guarantee for driving safety.

Required reading for long-distance driving! Three basic skills! 8 safe driving skills!

1. Three difficulties in long-distance driving?
To enter a strange environment for long-distance driving, the difficulties you encounter are mainly divided into three aspects. The first is to know the road. Driving is different from taking a car. You don’t have to know the road, but you must have a good sense of direction and be able to read all kinds of road signs; The second is to master the basic driving skills. You will encounter emergencies such as overtaking at high speed, driving on mountain roads and meeting in curves, which requires you to be familiar with the application of technologies such as lighting, braking, gear shifting and driving prediction; In addition, when the vehicle runs on township roads, the probability of the tire being punctured by stones is not low. Can you change the tire yourself? For the veteran, it can be done in a few minutes. It is extremely difficult for the novice. If the tire burst occurs in the middle of the night, how will you deal with it?

2. Six safety checks for long-distance driving?
The probability of vehicle failure and traffic accident in long-distance driving is much higher than that in urban driving. Therefore, six safety inspections should be strictly carried out before long-distance driving. One is to check and supplement the stock of engine coolant, brake fluid, booster oil and engine oil by referring to the oil suggestions in the vehicle manual; The second is to visually observe and touch the tire surface to see if there are wear, cracks and bulges, including four tires and spare tires, so as to prevent the risk of tire burst;
The third is to prevent the risk of ineffective braking by checking the thickness of the brake skin and whether there is virtual position or too soft when stepping on the brake pedal during normal driving; Fourth, check whether the accompanying tools are complete, so as to avoid the risk of simple failure without maintenance tools on the way; Fifth, check whether the wiper operates normally to ensure safe driving in rainy and foggy weather; The sixth is to check the lights to ensure the safety warning of vehicle lane change, overtaking and midway parking (this article is original, cat vision car starts, please indicate if it is reprinted)

3. Eight safe driving skills for long-distance driving? che
Safety is the primary consideration for long-distance driving, which is mainly affected by travel preparation, driving status and driving habits. At the level of travel preparation, first, be familiar with all vehicle functions of the vehicle, especially GPS, constant speed cruise and other complex configuration functions. Remember not to study while driving, which will distract driving attention and bring traffic risks; The second is to bring all relevant certificates and cash, such as ID card, driver’s license, driving license, insurance policy, mobile phone and some cash, so as to prevent the traffic police from checking, car failure or accident. You can also contact relevant parties (this article is original, cat vision car starts, please indicate if it is reproduced);
In terms of driving status, first of all, we should pay attention to the harm caused by fatigue driving. It is recommended to travel together and drive the car in turn. If there are no other drivers, it is recommended that the owner take a half-hour break every two hours. Don’t take a ten minute break after driving for 4-6 hours because he is eager to return home, especially for novices; Secondly, do not drive at night. You may take it for granted that there are few cars at night and it is safe to drive at night. However, driving at night is easy to make the driver sleepy, and the sight at night is not good, which is more likely to lead to traffic accidents; Moreover, don’t overload. You may think that the traffic police will only catch the bus overload, not the car, but overload is actually illegal. When the traffic police check the rebate car, and the space of private car is limited, adding one more person will increase the risk of car accident;
In terms of driving habits, the first thing is to drive at a constant speed, which can not only effectively reduce the risk of overspeed deduction, but also reduce the level of driving fuel consumption; Secondly, do not change lanes frequently, especially do not drive alternately, and do not slow down and stop without warning. At the same time, avoid driving side by side with trucks, buses and other taxis. These bad driving habits will increase the risk of traffic accidents; In addition, you should be careful when overtaking. Before overtaking, you should pay attention to the direction lights and overtaking signals. At the same time, observe the distance between the front, rear, left and right vehicles to see whether the overtaking conditions are met. Once you decide to overtake, you should never hesitate.

If you have to drive long distances, you can buy LS505 from leisure auto to remind tired drivers

The attention warning system can give a warning before the driver is sleepy. When the long-distance driving enters the dark environment or monotonous repeated environment, the risk of the driver falling into short-term sleepiness will reach the maximum.

At this time, the driver is very prone to distraction in a short time. Research shows that after four hours of continuous driving, the driver’s reaction speed will slow down by 50%, doubling the accident risk. After six hours of continuous driving, the accident risk rate will increase more than eight times! Mercedes Benz accident research experts have noticed the danger of drivers dozing off. Through careful investigation and research, Mercedes Benz found that about 25% of serious highway accidents originate from the driver’s drowsiness, so the risk of short-term drowsiness is much greater than drunk driving. Therefore, the new generation of S-class models in 2009 are equipped with a new attention warning system to remind the driver to stop and rest by identifying the signs of drowsiness. In the first ten minutes of each driving, the attention warning system will automatically generate the driver’s personal status, and then continuously compare the current sensor data with the original information. This form of continuous monitoring is of great significance to detect whether the driver changes from awake state to drowsy state. Once the driver is found to be sleepy, the system will give an alarm in time to arouse the driver’s attention. In order to ensure the driver’s safety when driving at high speed, the attention warning system will start automatically when the vehicle speed reaches between 80 and 180 km / h.

LS505 from leisure auto, is the best choice for aftermarket commercial vehicles.

Some vehicles are equipped with a fatigue monitoring system called “attention assist system”, which will constantly detect the driver’s driving mode. There are 71 sensors on the vehicle to detect the steering wheel and pedal sensors of longitudinal and transverse acceleration within the speed range of 80-180km / h. The system can sense that the driver is driving tired and prompt that he should rest properly.

Attention assist system engineers, cybernetics scholars, mathematicians, it experts and psychologists from Mercedes Benz R & D center and Daimler R & D department have been studying drowsiness, a root cause of malignant traffic accidents. The aim of these scientists is to develop a system that can detect the driver’s fatigue and quickly remind the driver. In the new generation of E-class cars, this innovation will be unveiled for the first time. It is named attention assist.
Drowsiness is a natural phenomenon, which is a deceptive response of the body, so drivers often fail to notice this phenomenon. You need sleep when you are very tired, but many people still choose to continue driving, which will bring great potential danger.
In this case, the driver may enter a state called “micro sleep” by experts, which is the spontaneous response of human organs after fatigue. Itchy eyes, blinking more and more frequently and slowly, pupils gradually shrink, drivers begin to yawn and tremble – these are the manifestations of micro sleep. But in driving, even closing your eyes for a second can have fatal consequences. Because in this short moment, a car with a speed of 100km / h can travel 28m! Once the vehicle is driverless, everything will get out of control. Scientists have found that in the micro sleep state, even if the driver’s eyes are open, what he sees may be deceptive pictures. In this case, due to the influence of the brain, the perception ability of the driver’s eyes becomes very slow and the reaction time is greatly prolonged.
In the process of studying how to detect driver fatigue, Mercedes Benz experts use a variety of test systems, from eyelid monitoring to EEG scanning (EEG). However, the first test results show that only one or two factors are not enough to correctly distinguish the fatigue state.
“Fatigue is a very complex phenomenon, and its manifestations are different in various cases. Therefore, it is necessary to consider a series of factors including driving mode, driving distance, driving time and traffic conditions.” Dr. J ö RG Breuer, the project director responsible for the development of attention assist systems, explained. The attention assist system developed by Mercedes Benz needs to detect more than 70 different limiting factors.
The main task of the research and development of the attention assistance system project is to detect the gradual process of the driver from waking to drowsiness, that is, from being able to concentrate all his attention to completely losing his attention, and remind the driver before he becomes tired.
In order to obtain this information, the attention assistance system generates a driver’s image before driving, and compares the image data regularly with the sensor data during driving, which can play an extremely effective role in the observation of driving behavior. It is difficult for over tired drivers to maintain the current driving route, so there will be some steering errors that are easy to avoid during normal driving. Dr. Breuer said that a survey of more than 550 drivers showed that this phenomenon appeared just before entering the state of fatigue – usually before entering the dangerous micro sleep.
If the attention assist system detects some signs of excessive fatigue, it will warn the driver with a special voice or through the display: “please take a break.”
The attention alert assist system is activated automatically when the vehicle speed reaches 80-180 km / h. Through more than 70 preset programs, the system continuously monitors and automatically judges whether the driver is in a state of fatigue or distraction. Once the system determines that the driver’s state reduces driving safety, it will send an audio warning signal and flash the prompt message of “please take a break” on the instrument panel display. With this technology, it has brought great help in driving active safety.

For the vehicle has no “attention assist system” pre installed, the LS505 from Leisure auto is recommended.

Leisure Auto Security Equipments Ltd, established in 2009, is a factory dedicate in car safety products, especially driver fatigue alarm system. the new products driver fatigue alarm is a fruit of our 8 years’ research and development, it is different from any other kind of system on the market, it is the best way to monitor the driver’s status.

It adopted the most advanced non-contact infrared camera to capture human eyelid and retina status,( in general, before entering drowsy

driving status, human retina was less and less sensitive to the light outside), analyzes the driver’s fatigue status according to PERCLOS method, and give out voice alarm before the driver falling asleep.

It can also detect the driver’s distraction and give out voice reminders to prevent accidents, such as talking with back passengers, adjusting audio, or operating navigator, pick up thing from the ground and so on.
