Everyone has it driver there is a special opinion about the comfort of the car. For one, comfort is a unique hydraulic suspension, for another, air conditioning, for others, powerful audio and video systems are pleased. Another innovation car tuning - this is ... For lovers of the unusual tuning you can see recommendations on how to do it yourself on the AvtoNovator website lED backlight, which gives not only aesthetic pleasure, but also has practical value.

Also, someone, creating coziness in the cabin, covers it with heat-insulating materials so that in winter the summer temperature is always kept inside. Many drivers appreciate vehicle comfort for noise insulation and vibration car... Loud music lovers are always annoyed when noise engine or road noise drowns out music sounds.

But, surprisingly and not paradoxically, it is a comfortable car that becomes potentially dangerous. Car manufacturers, in their desires to make a beautiful toy out of a car, with a mass of additional accessories, thereby render a disservice to car owners. Statistics and expert data confirm this idea and warn of an increase in the number of accidents in the row of comfortable cars. Swedish researchers, analyzing this problem, came to the conclusion that drivers will have great difficulty in controlling the machine. According to scientists, cars equipped with a noise insulation system are in demand among young people drivers with little driving experience. The boys in this case belonged to the road noiseas a distraction that prevented them from listening to music in the cabin car... However, the opinion of professional drivers regarding noise on the road is completely different. They believe that isolated from noise It is difficult for a car to have an idea of \u200b\u200bwhat is happening around, and it is impossible to fully assess the situation on the road. Professionals believe that all sounds coming from outside to the passenger compartment signal a danger and are therefore useful in the process of movement. By the sounds that come through, you can determine the quality of the engine, which road, with which surface it is driving carwhich car is approaching to overtake.

Therefore, Swedish scientists issued an appeal to automakers not to create for drivers vacuum conditions. Noise plays, as it turned out, not only a negative role. Road noise reminds driverthat he is driving on the road to carinstead of lying on the couch at home and listening to music. By the way, scientists from Sweden were supported by people from public organizations of the visually impaired and the blind, for whom cars with a weak engine sound are dangerous.

Of course, as they say, you can't forbid living beautifully. It is always pleasant and easy to ride with comfort, when cheerful music is playing, outside the window is frosty, and in the cabin there is a tropical climate. And I don’t think at all about what is happening there on the road, and what awaits you around the next turn ...

The study of the working conditions of drivers indicates a significant value of the parameters of the internal environment in the car. These parameters are only more or less likely to comply with the established standards, which makes it possible to extend the concept of reliability to a system that provides living conditions for people in a car.

Operational observations are indirect evidence of its insufficient reliability in some cases. According to the results of a survey of 4 drivers of this car about the influence of internal environmental factors, the temperature regime in the cab (hot in summer, cold in winter) was negatively assessed - 75% of drivers; the presence of toxic substances (air pollution with exhaust gases) - 75%; the influence of vibrations - 75%, noise - 75%.

Abnormal climatic conditions in a car cab have a detrimental effect on the driver's health and are one of the reasons contributing to the occurrence of an accident. Under the influence of high or low temperatures in the cab of the car, the driver's attention is dulled, visual acuity decreases, reaction time increases, fatigue quickly sets in, errors and miscalculations appear that can lead to an accident.

A survey was also conducted on the state of noise in the car and 100% of the respondents state the presence of mid-frequency noises from the low quality of the interior plastic, which causes increased irritation during the trip, although they do not exceed the 2nd class of noise according to GOST R 51616 - 2000.

Based on the above, I conclude that the driver's comfort in the car is significantly low, which leads to a decrease in the active safety of the car.

3. Systems of passive safety of the car

Passive safety includes many elements, and one of the main ones is the seat belt. The second most important element of passive safety is the car body. Its front or rear part should, collapsing, dissipate the released impact energy as much as possible, and the central part of the body should provide as much space as possible for the car passengers to survive. Interior materials should not only be pleasant to the touch and pleasing to the eye; if necessary, they should soften the impact as much as possible. At the same time, they should not crack, so as not to cause additional damage to passengers with their fragments.

After the impact, the car's gas tank must not ignite or crack to prevent fuel spillage on the road. Great importance is attached to doorways and locks. As the statistics of road accidents show, the most serious injuries, often incompatible with life, are received by passengers who fell out through the opened doors of the car. At the same time, after an accident, locks and doors should be easily opened without the use of additional equipment to ensure quick and timely evacuation of people in the cabin.

Combined from a number of factors, often contradictory, passive safety serves to achieve one main task - in the event of an accident, regardless of its severity, to do everything possible to save the lives of people in the car.

Based on the study of the safety of the ZAZ 1102 car carried out by the Autoreview magazine No. 3 2004. "The hood as a murder weapon"

(A crash test of this car was carried out; the nature and severity of the damage received by Tavria left no doubt about the outcome of the collision for this car.

The front part of the Tavria was crumpled thoroughly - 62 cm on the left side. At the same time, the entire front part shifted noticeably to the left, two solid folds appeared on the roof - the body went with a screw. From the impact, the windshield shattered and flew out, the driver's door was jammed in the opening.

The base of the A-pillar shifted back by 33 cm, which contributed to the contribution of the spare wheel - it pushed part of the engine shield into the cabin, and the hard plastic instrument panel moved back and cracked slightly to the left of the center, forming sharp traumatic edges. Miracles happened to the steering column and driver's seat. The column went to the right so that the steering wheel was almost in the middle and at the same time shifted inward by 14 cm. The left seat moved forward by 13 cm, and in addition, it was strongly skewed to the left. This happened due to the fact that the power structure of the body floor in the area where the front seats were attached turned out to be too flimsy - the floor went in waves, the seat sled bent, and they opened without holding the chair. Together with the deformation of the floor, this reduced the space for the feet and legs, and in addition, after the dummy bounced back, its head missed the headrest, which is fraught with damage to the cervical vertebrae.

It is also unpleasant that the rear seat backrest locks opened from the impact and allowed it to fold. The decoded data from the dummy sensors showed that the total level of overloads acting on the dummy's head for 20 ms was higher than the permissible level.)

Imagine our surprise when, when looking at high-speed filming frames, we saw a strange and terrible picture: the hard object that the driver hit his head against turned out to be ... the hood! Even during the first inspection of the body, we noticed that the emergency hood lock on the left side did not work. The right hook did its job, and the left hook just came off "with meat" on impact! In general, this is not surprising - the hook is welded to the engine shield cantilever, and in a collision, all the spot welding places (there are four of them) worked to tear off. The hook came off after just 30 milliseconds, and over the next 60 ms, the sharp edge of the hood broke through the windshield, which caused it to be swept out of the opening and moved into the passenger compartment towards the dummy. The high-speed footage clearly shows how the mannequin hit its face on the sharp edge of the hood. And this despite the fact that the belts were tightened as tightly as is hardly possible with normal driving.

The analysis of the residual deformation of the car body showed that Tavria has a weaker body structure, seat and steering column.

One of the main criteria when choosing a car, which is guided by 90% of buyers, is just the level of comfort. Determining what comfort is at the same time is both simple and difficult, because until now it is impossible to articulate exactly what it is. And only in general terms can we note that comfort is what makes our life easier and more convenient.

With regard to cars, manufacturers have brought some of their developments into a separate group, which is called the comfort system. In fact, these include almost all the advantages of a single car: visibility, fit, simplicity - all this, you see, creates one or another level of comfort. Nevertheless, in order to figure out what it is - the comfort of modern cars, we decided on a very rough, but at the same time understandable classification of comfort systems:

• Direct comfort systems;
• Comfort enhancement systems

What are direct comfort systems?

What can we attribute to the first group? What does the motorist constantly face? Of course, this is the driver's seat. A huge number of innovative systems and technologies are aimed at making the driver's and passenger's boarding as comfortable as possible. As a result, modern cars are equipped with electric ones instead of banal mechanical seat adjustments. The more you pay, the higher the comfort level. That is why BMW is equipping its luxury versions of its vehicles with variable geometry seats. For example, the lateral support of the seats changes, their length increases so that the legs are as little as possible in tension. Or, for example, the driver's seat memory system - is it not a comfort system? Therefore, comfort is also different.

To direct comfort systems, that is, what is used constantly and is already considered in the order of things, one can include either, etc. All this also creates a high level of comfort and is in use all the time. The list of systems can be endless, since everything that is done in the car is done for the comfort of those who will be in this car.

Comfort enhancement systems

What is meant by this group? For example, there is a car with a basic comfort system, which we talked about earlier: automatic transmission, power steering, etc. Comfort enhancement systems are those that are not used constantly, but only under certain conditions. For example, a system that connects only when the driver hits the track. On the one hand, the car already has a high level of comfort, but it is possible to make the movement even more comfortable with the help of such systems that operate under certain circumstances, in certain conditions.

In addition to the cruise control, we can also mention the control system, the intelligent system, etc.

The main rule of comfort

All innovative systems that are being introduced into cars, in fact, only cloud the mind of a person, and he, seeing how many useful options one car has, turns away from the one that has a simpler package, but at the same time is more comfortable.

What are the main criteria for comfort, which should be followed? This is not at all, in the form of heated wipers, remote start of the car, or. Yes, all this is certainly important, but there are systems that are decisive. These include characteristics, because it is very important how the car behaves on the road. For example, it can be stuffed with electronics, which supposedly increases comfort, but the part will be designed in such a way that each hole will penetrate into the cabin. Yes, with this state of affairs, you will not want any of the latest technology, you will be ready to give everything for a high-quality chassis. For the same reasons, noise, vibration and sound insulation can be considered. Comfort is unimaginable without silence. The characteristics of the engine, the same automatic transmission that we remembered about, are the main and main parameters that affect the comfort of the car, and all other electronic systems are just minor additions to what is already available.

If the car is not comfortable, then after traveling, especially for a long distance or in case of idleness in traffic jams, it will cause you fatigue and irritation. Unfortunately, Russian roads leave much to be desired, and not all car brands can boast of comfort and convenience.

But we must admit that most modern cars have become better in terms of reliability, quality and comfort. However, there are models that have a huge advantage over other brands in terms of comfort. We offer you our rating of the most comfortable cars. selected for comfort while driving, noise isolation, comfort of the driver's seat and front passenger seat. We have deliberately excluded from our list compact small cars, sports cars and convertibles, which by definition cannot be perfectly comfortable due to their size or design features.

Also, having familiarized yourself with the best cars for comfort, you can also find out if these models, as well as what they have, by clicking on the photo or the model name.

The A6 is very convenient and comfortable. Even the most experienced driver will like a ride in this car.

This year's new Impala is a modern large sedan. Spacious interior, comfortable, quiet and pleasant to drive. The large and spacious front seats are noteworthy. They are pleasant to the touch and perfectly support the lower back and relieve stress on the back, which allows you to comfortably travel long distances.

One of the best sedans on the market. Space and comfortthe main merit of computer engineerschrysler. Top-end equipment is the best. The control of all vehicle functions is very convenient. Various amenities, luxury items and quietness during the trip will not let you get tired while driving. It is especially ideal for a car on the highway, where you will not hear the loud operation of the engine and the sound of tires.See also:

The highest comfort is available in a top-of-the-range vehicle. The cabin is quiet. The noise only comes from
ventilation climate control. Also, some noise will bother you for several minutes after starting the engine in cold weather. After warming up, you will not hear the sound of the motor. The front seats are well shaped and very comfortable thanks to the support of the lower back. It should be noted that it is the leather seats that hold the back better than the fabric chairs. Plus, the fabric-trimmed seats are somewhat stiffer than the leather ones, which can lead to fatigue on long trips in traffic.See also:

Complete silence in the cabin. Even at high speed, no wind noise is heard. The interior of the Lexus ES is thought out to the smallest detail.
Maximum comfort. Expensive interior trim pleasantly surprises with its textures. ES models have very quiet engines and expensive noise insulation. The seats are distinguished by their comfort due to their width and balanced softness.Reliability rating

Lexus LS The flagship sedan provides both the driver and passengers with a comfortable and calm journey at any distance. The LS on the road won't be a hassle on any road. Soundproofing at a height. Absorption of extraneous noise is perfect. The smooth running of the car and excellent handling are the main advantages of this model. All seats are very comfortable and luxurious.

Fatigue is a condition that has arisen under the influence of the work done and affects the level of performance.

Fatigue is a complex and varied phenomenon. Often it does not directly affect the performance of work, but manifests itself in a different way. For example, labor operations that were previously performed easily, without any stress, automatically, after several hours of work, require additional effort, special attention. The rate at which fatigue develops depends on many factors: dynamic and static adaptation, visual comfort, work environment, etc.

Fatigue has a decisive influence on the driver's ability to navigate the road correctly, quickly and safely. Decreased performance due to fatigue is not a purely physiological phenomenon. As numerous studies have shown, an important role in the processes of fatigue belongs to psychological factors, the tension of the human nervous system.

In practice, the driver of a car (tractor) distinguishes between:

Natural fatigue, the consequences of which disappear the next day;

Excessive fatigue arising from improper work organization;

Harmful fatigue, the consequences of which do not disappear on the second day, but imperceptibly accumulate and remain unconscious for a long time until they suddenly appear.

The main factors causing driver fatigue and other abnormalities during work are as follows:

Duration of continuous driving of a car (tractor);

The psychophysiological state of the driver before going on a flight or leaving for a shift;

Driving a car (tractor) at night;

Monotony and monotony of driving;

Working conditions at the driver's workplace.

The most objective evidence of driver fatigue while driving is the number of accidents depending on the duration of the journey and other conditions associated with fatigue. An explicit dependence of the number of accidents and accidents on the duration of work has been established.

No less influence on the driver's fatigue is exerted by his psychophysiological state before leaving. It worsens from lack of sleep and stress on the driver before starting work (mental stress, an unnerving conflict situation, mental trauma).

Driver fatigue increases when driving at night.

With a monotonous and monotonous movement, a particularly dangerous type of fatigue occurs, which causes an inhibited state of the driver's higher nervous activity and can lead to weakness, drowsiness and falling asleep while driving. This condition occurs as a result of prolonged repetition of the same action.

No less important factors that accelerate fatigue are the working conditions at the driver's workplace (position at work, rhythm and pace of work, breaks in work), the microclimate at the driver's workplace (temperature, pressure, humidity, gas pollution, lighting, radiation) and noise and vibration level.
