Traffic rules

Nowadays, when purchasing a new car, you can request the optional installation of any system from the dealer.

This has become completely commonplace.

There are also options that are already included in the package, and you do not need to pay extra for them.

Among them is the SRS system.

What and what components does it include?

The answers to this question are available in our current article.
Characteristic
SRS – what is it?
This system is a complex of elements that are installed in cars, which allow changing the characteristics of road transport for drivers and passengers.
The SRS Airbag classification is based on its safety design elements.

This means that all of these components are installed not as an option (as can be installed with an air conditioner), but as a requirement.

And it doesn’t matter whether it’s a top-end configuration or a “base” one, all the same machines will have a new set of passive safety devices.

Thus, SRS is a set of structural elements that are designed to protect passengers and water from injury in an accident.

Warehouse systems The SRS system can include the following warehouses: is a set of various digital sensors and electronic devices.

First, select the function of fixing parameters that are in an emergency situation, and convert them into short electrical signals. This may include the position of the seat in the front row of seats and the use of a 3-point lock. As a rule, the car alarm installs 2 such devices on each side to react to impacts. These sensors are closely connected with the active head restraints, which switch to active mode when a signal is given.

Thus, the skin from the components of the passive safety system closely interacts with

singing sensors

And through the use of special impulses for treatment of a millisecond, it allows the Airbag and other storage areas to be inflated through the SRS unit.

Vikonyuchye devices

Among the various devices in the car, the following are listed:

Activation of the skin from these warehouses is carried out according to the installed software.

Characteristic
What devices can function in the event of a frontal impact?
When the frontal SRS is turned off, a number of safety elements can be activated, depending on their strength.
These can be both tensioners and pillows (possibly all at once).

With a frontal-diagonal connection, depending on the magnitude of the impact in the system, the following are activated:

Front airbags.

Pillows at once with tensioners.

Libyan right Airbag. In certain situations (including at a speed of over 60 kilometers per year), the system can activate all over-inflated elements, thereby ensuring maximum safety and minimal risk of injury to passengers in both rows of seats, as well as to the driver himself. What devices can be used for a barrel strike? In this case, depending on the vehicle’s equipment, either tensioner belts or airbags can be installed. The rest are installed on cars of the middle and more prestigious classes.

Budget cars do not have tensioners, which are used in the event of an impact, securing the body of a person in the seat.

These elements began to be equipped on cars much later than classic tensioner seat belts. The active head restraints are installed on the backs of the front and rear row seats in the cabin. The likelihood of such elements risking a fracture in the area of the cervical spine during a rear impact is reduced to a minimum (even this area itself is one of the most susceptible to fractures).

In this way, active headguards significantly increase the chances of life after what would seem to be fatal blows.

The first copies of such devices began to be installed on German Mercedes. Based on their design, head restraints are divided into two groups and can be either active or indestructible. In the first version, the headrest can be adjusted in height and height.

Restless analogues are firmly woven into the backrests of the seats.

However, such head restraints miraculously cope with their main function - reducing injury safety during

Shut up.
Well, we understand what the SRS system is in a car and what it does in case of various problems.
About those who also have SRS in a car are well aware of those who drive daily cars.
However, it’s too early to learn about this process and motorists-cobs, the debris is often scattered so that on the fender panels they “

The SRS Airbag classification is based on its safety design elements.

» Indicator to indicate that there is a problem with the system.

The front airbags are deployed directly in front of the driver (at the steering wheel) and the front passenger (at the dashboard), and the side airbags are located at the sides, at the seat backs and side elements of the body.

This design has special cartridges filled with dry gas and generated by electrical impulses.

Touch sensors (pressure sensor and backrest position sensor) are located in the seats, and the acceleration sensor (often called the acceleration sensor) is located at the front of the car, directly behind the grille.

It is controlled by the pendulum principle, and when its position changes sharply as a result of the swing, the electric lance closes, thereby generating a control signal that is transmitted to the head SRS module.

Most of the valves are located in the tunnel channel (or more precisely, at the front part), and its most important function is to control such elements of the SRS system as the airbag module and front tensioner belts and safety.

The rest are exactly the same as the touch sensors, which are installed in the front seats, equipped with piston cartridges: when pressed, they themselves collapse and even tighten the belt too much.

It is understood that active head restraints are also located on the seats, being mounted on the upper parts of the backrests.

The vehicle's SRS system is adjusted in such a way that it is only operational emergency situation X. It doesn't work, for example, when you're stuck in bushes or covered in snow.

If it detects an impact from the rear, then the signal for activation is sent directly only to the active head restraints, and if the impact is from the side, then the airbags are not required (in these cases, obviously, since they are installed on the my cars).

Servicing the SRS system

The SRS system often does not work, but once every ten years it is necessary to undergo further diagnostics.

After washing the airbags, they need to be replaced again, and any debris is disposable.

When operating the SRS system, make sure that its elements (especially the sensors) do not heat up above +90 °C.

It is also necessary to remember that the effectiveness of this vehicle’s passive safety system has a lot to do with the extent to which the water and passengers are properly installed in the vehicle’s interior.
For proper operation of seat belts and active head restraints, it is necessary for the seat backrests to be tilted slightly more than 25°.
Moreover, the seat cannot be placed too close to the airbags.

SRS benefits As has already been said above, the SRS system is complex due to its design, and therefore, its robot can periodically suffer from various faults. As practice shows, calls are most often made for such reasons as:

Faulty wiring or contacts;

Problems with the electronics of core modules; There is a broken terminal and burnt-out terminals..

Regardless of the SRS application, it is not recommended to apply it on your own.

It is best to crash into the station if you are guilty technical service

It is our responsibility to carry out thorough diagnostics of the system and identify the problem.
Special sensors and sensors that monitor the fluidity of the car, that record the moment of impact when impacted, the position of people in the car interior, etc.;
Front and side airbags;
Special seat belt tensioners.

Note: the SRS safety system in the car helps to protect the health and life of the driver and passengers in case of accidents, in which the system responds when the vehicle speed exceeds 50 km/year for frontal and high-impact impacts.

Also, do not forget that SRS does not respond when contacted by soft objects (for example, when driving into a snow field), as well as in the event of a rear impact (for example, when your car crashes into another car from behind).

Why bother if the SRS light is on on the dashboard?

The main points from what has been written above immediately become clear to the fact that it is obligatory to monitor the SRS system in the car, so that your safety may be affected.

As soon as a problem begins to appear (indicated by a signal on the device panel with the SRS icon), it is best to contact the car service center so that they can carry out a diagnosis and fix the problem.

The good thing about the SRS safety system is that it doesn’t need to be serviced frequently, but it needs to be checked every 9-10 days to get to the help desk, but it’s important not to forget that the airbags and the fire cartridges before them are disposable at times asking for emergency situation, it needs permanent replacement.

In conclusion, you can say that if you know what SRS means in a car and how important this system is, then you will be more respectful of it. Your vodguki and for the sake of the cinnamon On the topic of what is SRS in a car, we will leave it in the comments until the article is shared. social measures

Yakshcho there was a korisna for you. Safety systems that can be equipped with current cars

, Divided into two main categories - active and passive. And it all started with the installation of safety belts, which is also one of the main safety features. Place the belt on the passive safety systems.

Other significant passive features include safety cushions.

The belts are very tight when worn, they ensure good fixation of the tubular fabric, otherwise they are not suitable for pillows.

And since they were previously installed only on premium cars, they also stink with cars in the budget segment.

The number of pillows is growing too much.

Main warehouse elements
The airbag system includes three main components:
Shock sensors

Keruvanya block

Main warehouse elements

Gas generators

More modern systems include additional sensors and mechanisms that make significant adjustments to the operation of the security device.

Impact sensors are the elements that make up the entire robot system.

The stench itself indicates that there is a problem, why should you ask for pillows?

At first the front sensors were stuck. The number of pillows used to be small and the current goal was to improve injury protection in frontal injuries. Nowadays, cars are equipped with a lot of other devices, which is why the number of sensors has grown.

The principle of operation of the capacitor sensor is based on rapid change of capacitance by means of displacement of the plates.

And you can reach the bottom of the plates of the capacitor and fasten them on different bases, one of which is unbreakable, the other is unbreakable.

Upon impact, the very force of inertia displaces the crumbling base with plates so that it is indestructible.

As a result, the capacitance of the capacitor sensor changes.

This fixes the processing block, extracts the data from the tabular ones and, based on this, forms a signal to the fixed block.

This principle is followed by other types of sensors, the same difference being made to their device.

The airbag system includes three main components:

All of the changes in inertia depend on the parameters that form the basis for the signal shaping by the processing unit.

It is important that the adjustment of the shock sensors takes place outside the installation site. So, the side elements are sensitive, lower frontal. To detect impact, sensors can be installed in the door frame to detect changes in atmospheric pressure in the car doors.

The stench is piezoelectric and omnismic.

The first type is based on the piezoelectric effect, and the other is based on the principle of a capacitor sensor.

The main storage element of the system is the final mechanism – the gas generator.

His task is to generate a large amount of gas in a short period of time, which will then replenish the pillow itself.

The gas generator includes a number of storage elements - a pyrocartridge, a charge of the speaker that produces gas and, finally, the pillow itself.

The cartridge is used for firing a charge.

The cost can be obtained in two ways - by melting a shot placed in a combustion chamber, or by using a capsule that creates a semi-flame front in the chamber with a charge.

It's simple - an electrical signal from the control unit is supplied to the fire cartridge, which causes the wiring to melt or the capsule to burn.

The combustion chamber of the gas generator is filled with liquid, as it was created in the short term to burn out, having seen a great consumption of gas, which is safe for people.

As such, it is necessary to use sodium azide (which, before speaking, is irreversible).

In the process of combustion, alcohol breaks down into harmless substances - nitrogen (45% of the liquid), water, carbon dioxide, and solids.

When struck, the charge in the main chamber burns out.

With this, the surface of the pillow is inflated by 80%.

This way the bag comes out soft and is completely filled, which reduces injury when a person comes into contact with the pillow.

After a period of an hour, the cartridge of the additional chamber is discharged and the pillow is replenished with gas, even after it has received a blow to the body.

Additional facilities

The SRS system device can optionally include a passenger presence sensor and an emergency door lowering mechanism.

The control unit can also control the operation of the front tensioner belts (with cartridges).

The passenger visibility sensor is necessary so that the control unit does not touch the front passenger airbag, since there is no one on the back seat.

Previously, connecting the pillow was done manually, which was not very easy.

It is important that the main disadvantage of pillows is their disposability.

Then the stinks are created only once, after which they need to be changed.

And a replacement is very expensive, so auto owners of cars, for which the stench was concerned, are trying to “cheat” so that the system is diagnosed normally when starting the engine and does not get a warning light that is constantly burning. Vidi Vikorist on current cars

The main ones are:

Front driver and passenger (installed in the kermo and front panel);

Scoops (mounted at the back of the front seats);

The smut, the stink of the curtains (rotted at the barrel racks and dahu).

Regardless of the SRS application, it is not recommended to apply it on your own.

Why bother if the SRS light is on on the dashboard?

The main points from what has been written above immediately become clear to the fact that it is obligatory to monitor the SRS system in the car, so that your safety may be affected.

These types of airbags are installed on many models, including budget options.

Frontal signs are used to reduce injury during frontal impacts, two other types are used for side impacts.

When familiarizing yourself with the characteristics of the car, you can often see the abbreviation SRS in the list of options.

Few people can boast of this if they know what kind of system it is. Having read this article to the end, you will also be able to date the lit power supply: What is SRS in a car?.

SRS (from the English Supplementary Restraint System) will ensure the protection of water and passengers when the windshield is exposed to a static or loose object The main goal of SRS is to minimize injuries to drivers and passengers during road traffic.

Airbags and seat belt tensioners must be adjusted immediately to prevent the driver and passenger from hitting the roof.

or other solid objects that are around the car interior. To implement this, the system analyzes the pulse signals of the vehicle, evaluates the force of the impact and decides to activate the airbags and/or the front tensioner seat belts. In this case, the seat belt tensioners can be activated either with or without airbags.

Airbags are designed in such a way that they are activated only in the event of a frontal or rear impact, if the impact is from the rear, then any tensioners of the seat belts or airbags do not function.
