How Volvo hatchback V40 Pedestrians Airbags Work

Volvo hatchback V40 boasts the world’s first pedestrian air bag safety which inflicts less damage to the passersby even if the accident seems to be very horrible. No other car has ever drafted or tried to incorpate this technology while making. Its so astounding to see this from Volvo. Three cheers to Volvo India for this spectacular design.

Volvo worked hard to make its vehicles safer for pedestrian too, so after releasing the so-called Pedestrian Detection system that could even apply full brakes to avoid a collision, the debut of the new technology was more like a matter of time.

We all know that, this new car got launched yesterday and this beauty is scripted in such a way that it prioritizes passenger’s safety at the first hand. Volvo V40 has a total of 8 air bags. Sounds very cool, right? As such this new bringing from Volvo will trigger upcoming cars to draft this technology and sooner there will be any accidents. The author here is completely stunned about the technology; even he himself has no idea about the technology. Come let’s go deep into the study of How Volvo V40 works with the Pedestrian airbags

How does it work?

The system only works at speeds ranging in between 20 and 50 km/h, which is quite okay given the fact that most accidents involving pedestrians occur at city speeds.

Just like any other airbag, this innovative system especially aimed at pedestrians is based on sensors and a control unit. Pretty simple, isn’t it? It looks so, but in reality, the whole idea is a lot more complicated.

An army of seven sensors defend the front side of the car, keeping an eye on every single collision that might occur. Under the hood, a control unit receives every byte of information and allows the available systems to act accordingly.

Basically, the moment when an impact is about to happen, the front sensors send information to the connected control unit which, in its turn, analyzes the information to detect the shape of the object. In case it determines that the car is about to hit pedestrian legs, the control units activates the airbag.

But how’s that possible? You may ask. Well, the Swedish manufacture says the new technology is based on lots of tests that involved human-like dummy legs and heads that could simulate a real accident as much as possible.

Mounted at the bottom of the windshield, the airbag can cover not only the surrounding area of the wipers, but also one-third of the windscreen and the lower part of the A pillars. But only when inflated, of course. In other words, the airbag can cover exactly the areas likely to be hit by the adult pedestrian head in the unfortunate case of an impact.

Just like any other airbag, the pedestrian system is based on a sack and a gas hybrid generator that’s responsible for filling up the sack with gas according to information sent by the central units.

And because accidents involving pedestrians may vary a lot, the bonnet has been configured to contribute to pedestrian safety, too. If the system interprets the object as a human leg, it first releases the bonnet hinges by firing two pyrotechnic charges. Almost immediately, the airbag inflates, raising the bonnet by 10cm in the process to help absorb some of the impact.

This way, the airbag plays not only a key role in protecting pedestrians directly, but it’s also an important piece of a larger system supposed to bring a great contribution in this regard. The choirmaster is however the remote control unit that’s supposed to take care of everything, just like it happens in traditional airbags too.

The exposed area of the airbag covers the lower edge of the windscreen and the A-pillars – the bits of the car that cause the most serious head injuries.

How much does it cost?
All V40s are fitted with the pedestrian airbag as standard, although you will have to pay to have the system reset if it ever goes off.

That’s unlikely to worry you if you’ve been unlucky enough to hit someone. However, there’s always a chance the airbag could be set off by something else – an animal, for example – that the system has wrongly identified as a person.

Either way, you – or your insurance company – will need to fork out around £500 to have the airbag replaced. There will also be an even bigger bill for a new bonnet, which will be damaged by the airbag firing.

However, given Volvo’s claim that the system can reduce pedestrian fatalities by 5% and serious injuries by 14% that seems a price definitely worth paying

And today, Volvo has created some history.
