When the crash sensors identify a vehicle collision, the ICR system is triggered, causing the airbags and safety belt tensioners to deploy. As a result, the passengers can quickly and simply get out of the car.

VW Intelligent Crash Response System: What is It?
All Volkswagen vehicles come with ICRS, which is intended to keep you safe in the event of a collision. Should a collision occur, ICRS will turn on and the airbags will deploy. The gasoline pump will be turned off, the danger lights will turn on, and all doors will automatically unlock thanks to ICRS.
What does the VW pre-crash system do?
- The most recent version of the pre-crash system can recognize threats behind the vehicle.
- System now incorporates Side Assist data for the first time.
Nobody wants to find themselves in this situation: red traffic lights, a glance in the rearview mirror, a car coming up too quickly, and the threat of a rear-end collision. The new, optional “Pre-Crash occupant protection system” in the Arteon now offers help to the fullest extent possible in such circumstances. For the first time, the Pre-Crash sensors are able to respond to hazards at the rear in addition to processes related to driving dynamics (detected by features like the ESC and severe risks of accident from the front, reported by Front Assist). The system makes advantage of Side Assist data for this. It can take action to mitigate the effects of any mishap wherever possible in a matter of fractions of a second.
This is how it functions: Pre-Crash makes use of the Side Assist system’s sensors, which, when overtaking, warns the driver of any vehicles in the “blind spot” to the extent possible. Side Assist may track the location and speed of the vehicles following the Arteon using radar sensors. The Pre-Crash system then analyzes this data. When the automobile is stopped with the engine running and in stop-start mode, such as at the previously described red light, it also performs this. The algorithm uses the position and speed of both vehicles to calculate the likelihood of a potential accident if the identified vehicle advances in the direction of the Arteon. The new Pre-Crash system responds appropriately if it recognizes an impending risk.
The technology simultaneously closes all windows (except from a small gap that enhances the bracing effect of the front head airbags) and the sliding sunroof as the hazard warning lights turn on and display the rear emergency collision alert signal. The front safety belts are tautened in tandem with this by the belt tensioners.
What triggers airbags to inflate?
When a collision occurs, airbags, which are inflatable cushions installed into cars, shield the occupants from being struck by the inside of the car or by outside objects like other cars or trees.
Sensors start measuring impact force as soon as a crash occurs. If the collision is serious enough, the sensors send a signal to the inflators to quickly inflate the bags with gas.
In most cases, airbags don’t need maintenance unless they deploy during a collision. In that scenario, they must be changed at a repair facility that uses OEM replacement parts to guarantee that the brand-new airbag is genuine. Airbags that are counterfeit may not deploy or may leak metal fragments when deploying.
How do airbags lessen the chance of getting hurt in an accident?
In addition to seat belts, air bags are an excellent form of additional safety. Frontal and side-impact air bags can both deploy in mild incidents and are typically intended to do so in moderate to severe collisions.
In the event of a collision, air bags lessen the possibility that your head or upper torso may hit the inside of the car. Make sure you are situated properly and keep in mind that air bags are made to complement seat belts, not to completely replace them, to prevent suffering an air-bag-related harm. And passengers under the age of 13 should take the back seat.
VW’s proactive occupant protection system: what is it?
Proactive occupant protection system This technology has typically been translated from the luxury class to the small sector and is known as the proactive occupant protection system. The most recent Polo now incorporates Volkswagen’s proactive occupant protection system, which was initially fitted on the Touareg. The driver’s and front passenger’s seat belts are automatically tightened if the system detects a potential hazard, such as if Brake Assist is engaged and an emergency stop is started, to ensure the best possible protection from the airbag/belt systems. The side windows (aside from a minor crack) and sliding roof are also automatically closed if a very dangerous unstable driving situation, such as severe oversteer or understeer with ESC intervention, happens.
System for proactive occupant protection on the new Touareg The proactive occupant protection system was upgraded for the new Touareg. PreCrash Front, PreCrash Side, PreCrash Rear, Rollover, and Multi-Collision are now all combined into one active system, which once more identifies more accident scenarios. The driver’s and front passenger’s seat belts are immediately tightened and the electric seat functions are configured to ensure the best possible protection by the airbags and seat belts if the system detects a potential collision scenario, such as when Brake Assist has been engaged. The side windows (aside from a minor crack) and sliding roof are also automatically closed if a very dangerous unstable driving situation, such as severe oversteer or understeer with ESC intervention, happens.
Automatic post-collision braking system: what is it?
The Post-Collision Brake automatically engages if a collision or impact cannot be avoided. Your automobile comes to a complete stop right away, avoiding any additional collisions with objects or other vehicles.
What is emergency braking for cities?
All models from the up include a system addition to Front Assist called City Emergency Braking! The device uses a radar sensor to scan the area in front of the Volkswagen at speeds up to 30 km/h. Similar to Front Assist, the system primes the brakes if the driver does not act in the case of an approaching accident with a vehicle in front of them or a stopped car. To lessen the severity of any collision, the City Emergency Braking function then automatically starts an emergency stop. Additionally, the system uses its maximum braking force if the driver does not apply enough force to the brakes.
Does insurance provide replacement airbags?
Yes, most policies will cover airbag replacement if you were in an accident and the at-fault driver’s liability insurance covered it, or if you have collision insurance that will cover damage to your car regardless of who was at fault. However, due to the high cost of new airbags and installation costs, some vehicles with a low cash value will be deemed a total loss by the driver’s insurance company if the airbags are replaced. For this reason, a driver may think of paying for airbag replacement and other repairs without consulting their vehicle insurer. This implies that your insurance company might think it is more cost-effective to declare your car a total loss than to fund repairs.
What gas does the airbag contain?
Did you know that driving is safer thanks to an extremely quick chemical reaction? The dashboard and steering wheel of most cars are equipped with airbags that, in the event of a collision, can inflate quickly like balloons to protect passengers from harm. What causes the airbag to bubble up? Chemistry! We use a very quick reaction that generates the required gas instead of transferring compressed gas in the car to inflate the airbag.
Numerous automobile airbag inflators include trace levels of sodium azide, or NaN3, a hazardous substance. When heated or subjected to an electric shock, sodium azide degrades very quickly. Decomposition is the term for this. The result of the breakdown is nitrogen gas and sodium atoms.
Sensors in the vehicle deliver an electric signal to the container containing the sodium azide in the event of a collision. The sodium azide begins to decompose as a result of the signal’s ignition of a flammable substance and the heat it produces.
Immediately after the explosion, a significant amount of nitrogen gas rushes out and fills the airbag. It is incredible that it only takes 30 milliseconds, or three hundredths of a second, from the moment the sensor senses the collision until the airbag is fully inflated! Your eye blinks normally for 100 milliseconds. The air bag absorbs the forward-moving energy of the person in the car about 50 milliseconds after the collision, preventing them from crashing into other sections of the vehicle. The day was rescued by chemistry!
It takes about five party balloons’ worth of gas to fill a typical air bag, but a comparatively tiny amount of sodium azide (4.6 ounces or 130 g) will produce a lot of nitrogen gas rather rapidly! Although the sodium metal product itself can be dangerous, in this instance additional chemicals combine with the sodium to create safe molecules.
Other scenarios when prompt gas production is required may come to mind. For instance, in the event of an accident, sodium azide is also used to pump up airplane escape chutes. How would you use this quick gas production if you were an inventor?

How many miles per hour does an airbag deploy?
The airbag will typically deploy at a speed of between 100 and 220 miles per hour. It’s crucial to stay at least 10 inches away from the airbag when it deploys because at this speed, an airbag can seriously hurt a person.
When a seatbelt is not fastened, will an airbag deploy?
The airbag will deploy at the same threshold (or level of collision severity) as a conventional airbag if the occupant’s seat belt is not fastened. As you may already be aware, occupant protection is continually improved by vehicle safety equipment.
After a collision, do airbag sensors need to be replaced?
The two most often used safety features in modern cars are seatbelts and airbags. Recalibration is one of the most crucial processes in the repair procedure once repairs are finished. This will guarantee that the car is repaired to its pre-collision state. Additionally, it will guarantee that in the case of another accident, these safety features will function as they typically should. But there is a process that needs to be followed.
Pre-scans
The technician must do a diagnostic pre-scan using the asTechTM device before beginning a repair involving seatbelts and air bags. It will be clear from this which Diagnostic Trouble Codes (DTC) were triggered.
Air bag sensors
Some crash sensors may reset themselves after a jolt, however without inspecting the sensor it might be difficult to determine whether it has been damaged or failed to reset. Replacement should therefore be taken into account. Before moving forward, it is always advised to review the OEM repair instructions. In addition to replacing the crash sensors, the technician might also need to replace the air bag module and airbags.
The technician should make sure the replacement sensor is the right one for that particular vehicle before replacing any crash sensors. Having the appropriate sensor for the vehicle is crucial because crash sensors need to be recalibrated for various vehicle applications.
A collision sensor may incorrectly or not at all activate the air bag if the mounting location is changed. As a result, the replacement crash sensor needs to be placed exactly where and how the original crash sensor was. In order for it to remain in place in the event of an accident, it must also be firmly fastened.
Seatbelt sensors
In the event of a collision, the airbag system signals the seatbelt igniter to light, activating and locking the seatbelts. Seatbelts must be replaced or repaired before being reset after being locked during an accident.
Each seatbelt features a retractor with a locking mechanism that activates in the event of an accident. A tiny explosive device known as an inflator is one of the seatbelt’s components. The igniter, which is in charge of fast deploying, will start the inflator. A sensor that will connect with the airbag system is in charge of all of this. After an accident, it will be necessary to replace the sensor, igniter, and inflator for the seatbelt to function properly once more.
Recalibration
It will be time for the technician to fully recalibrate when all the damaged components on the car have been located and replaced. A recalibration won’t be deemed finished until all DTCs and defects have been cleared and verified rectified. After recalibrating, a diagnostic post scan using the “asTechTM device should be performed to see if all repairs have been made properly and the vehicle can then be judged safe to drive.
