Benz shapes the safety

With the new ESF 2009, Mercedes’ plan for ever-improved vehicle with fresh ideas and innovation

Just when you you had airbags, stability control and brakes figured out, has ramped up its road-safety engineering the ESF 2009 safety research

Mercedes Benz’s ESF 2009 car (more here ) enters new territory by doubling a normal emergency braking power, side impact safety expanding metal ‘airbags’ the doors, automatically lighting up and animals at night, pushing towards the middle of the car away danger — and even to other cars! Plus, in is sure to be a boon for parents, the ESF even has a roof-mounted camera can show snapshots of rear-seat on a multi-media screen, while debuting an all-new modular seat. Benz says child-focused safety devices be in production in the very near

Timed to coincide with the Advanced Safety of Vehicles in Stuttgart, Mercedes-Benz gave the Network a sneak preview at its in Sindelfingen, Germany, to make the that current vehicle is still well short of is possible.

Mercedes-Benz has had thousands of engineers working away on to help avoid crashes as new LED headlight technology and car-to-car and to maximise safety in unavoidable

The primary aim is to prevent accidents in the place, said Professor Rodolfo Schöneburg, who is the German Director of Passive Safety, and Vehicle Functions.

Where is not possible, the aim is to mitigate their The ‘Magic Moment’ for passive innovations is 600 milliseconds before the and we use this time to significantly occupant protection.

But we approach of these goals without the weight, restricting practicality or the autonomy of the driver. The driver and the car provides support.

Built in eight months, the ESF 2009 is around the new S400 Hybrid (more here ). It also a new combined seat belt and for the back seat, sensors can detect a collision from any and airbags to stop the people in the seats from colliding each other.

That is no end to the development and refinement of safety is a tenet of Mercedes-Benz. Indeed, it be a new Benz model if it didn’t a new safety feature — be it or major. Here’s a rundown of the safety technology, Mercedes is on. Some of them could be new Mercedes models quicker you think.

Braking Bag

In the collection of safety that are the ESF 2009, none are than the Braking Bag.

A S-Class fitted with Pre-Safe Plus technology three different radar to detect crashes. If you ignore all its and the computers are convinced you’re to crash, it will automatically on the brakes, decelerating as hard as the and tyres can manage.

There is a to this effect, however, the tyres have only so rubber on the road and even cars will only at around 1g — 10 metres per squared.

The Braking Bag concept is developed with key supplier and can more than double power by setting off an airbag the engine, which pushes a rubber-lined version of the sump directly onto the road, off speed at up to 2.5g!

But it’s a affair, and can only be set off in an unavoidable And, because the bag pushes the nose up off the ground, the timing has to be

The key is that energy is not only at the wheels, Schöneburg said.

We to find the right time to the bag — and it’s about milliseconds before the crash. At that would be roughly 10 Too early is counter-productive and too late is too late.

It’s only to be when you have an unavoidable and our sensors already tell us We know 600 milliseconds before we can avoid the crash or not.

We see the with the sensors and at 5-7 milliseconds, the car whether it’s a front, or or rear crash.

Given how its timing and performance will be, expect more new technology to be at here, but the Braking Bag uses airbag technology — a twist.

This airbag inflates in 5 where a normal 60-litre airbag needs 15-20 said the Brake Bag’s Karl-Heinz Baumann of Benz’s Safety Concepts and Strategy

But this one isn’t folded a normal one. Because of it is, it’s flat and it’s We can detect an unavoidable crash in 5-7 then we only need 5 milliseconds to set off the Brake Bag.

The is surprisingly simple. Baumann it needs nothing special the normal undertray and that the standard retaining bolts do the job.

It’s just a under the engine. The only is to have an underbody which be bent down to the ground and the load to decelerate the car, he

The secret is we use the car’s braking. The car down and the idea is to push the car to the original position. This to an additional dynamic force and the friction for a short time.

are working with a variety of friction surfaces and even with ways to grip the other than just friction.

The main message is it’s not just possible to by the wheels and tyres. If an impact occur there are other and this is a new kind of thinking. is an idea which leads us to the

In Baumann’s tests in a C-Class, he stops from 70km/h and without the bag. When set the Brake Bag off, it was doing at the same point the normal car was at 50km/h.

That does not much, but it’s the difference a 50km/h and a 47km/h impact. If you a crash test against fixed barrier you will deformed 180mm of the front of the car to get to 47km/h. The effect is of a much front end.

Inflatable beams

Car companies can manage all of engineering tricks in a frontal because they can usually the first metre or so a crumple designed to sacrifice itself to the occupants a survivable crash. As as it sounds, the doors of the ESF 2009 what are effectively inflatable zones — steel

Side-on collisions where is no space for a crumple zone, are safety engineers fear the The obvious fix is to give the side of the car crumple zone, but that both shrink interior and add weight. Governments around the have long mandated protection beams, but what is calling Pre-Safe Structure even further. In short, it the S-Class’s side impact and turns it into a metal

While this technology is way off production, the basics are quite When sensors in the side of the car an unavoidable impact, they an airbag inflator (just the one in the driver’s airbag) inside the Like all airbag generators, one is a pyrotechnic-powered unit, meaning technically an explosive.

When this almost instantly the steel beam to triple its size — the pressurised gas adds to the strength of the door as as creating crumple zone.

it’s not used, it’s folded up to save space and it’s needed we build up the pressure to 10 to 20 Bar in a fraction of a second, said.

But it’s not just more to stuff in the door. has an eye on using the technology to strengthen like seat mounts and – basically any area vulnerable in a crash.

Surprisingly, the big problem the metal bags is not weight in fact calculates Pre-Safe can actually save half a per door) but rather cost.

now, it has to fulfill all the static and it has to do that now by staying un-deformed, so bigger, heavier and more than it needs to be, said Dr Nohr, Mercedes-Benz’s manager of Structure Concepts.

It won’t go to like this. There may be stage to figure out with a or aluminium design, but it’s all making the car’s body-in-white basic vehicle structure] intelligent.

But we only have one to get this right. It’s a good idea. The good is that it’s not too complicated, but the bad is that we have to find a to make it cost effective, he

Pre-Safe Pulse

Working on the that every millimeter in a crash — especially a crash — the Pre-Safe uses the critical 600 milliseconds space’ in an accident to inflate air in the seat side bolsters. pushes occupants around towards the middle of the car.

Though this doesn’t much, Schöneburg insists, it is to reduce the stresses on the torso in an by up to one third.

Again, the core isn’t new. Some models have had seats air bolsters for years. The new part is them into the heart and of the car’s communication systems.

Pulse doesn’t just to the news that there is to be a crash, though. A development of the new seat, it has a ‘brain’ able to in the steering angle, cornering and car speed to determine how much is required.

A good thing the Pulse system is that, the Brake Bag or the inflatable intrusion it is reversible and the seat doesn’t replacing.

The seat belt has hundreds of thousands of lives it was invented and has been improved three-point mountings, automatic and belt-force limiters. The Belt Bag another dimension to the seat

A seat belt limits the of the torso, but it also subjects the to considerable forces, Schöneburg

The belt bag practically doubles the of the belt to spread the pressure a wider area — the risk of injury. This is beneficial for older passengers, rib cages are no longer so flexible.

The Bag was developed with Autoliv and has a at the edge of the double-layer belt inflation to around four Benz considers that the bag be most useful in the rear because there is no way to fit frontal there.

We have children in the very often, so we don’t to have an airbag in the [rear of front seats for the rear Also, the front seats to suit the occupant, then move again with Schöneburg said.

Mercedes-Benz ESF 2009


Airbags were originally which compromised their benefits. While there are airbags on sale now, the ESF new bags automatically adjust volume to suit the weight, position and stature of the occupant.

The bags have a series of on electric reels. In a crash, the tells the bags how much to let out with the tethers, so they anywhere from 90 to 150 litres. front airbags inflate to 120 litres.

Pre-Safe 360°

The Benz system has traditionally kept an eye on in front of a car: the ESF 2009 is checking behind and beside as well. It scans up to 60 metres and applies the brakes if it senses an rear-end collision.

Contrary to the opinion, it does not make to take one’s foot off the pedal before an impending collision, Schöneburg said.

The action is to apply the brakes as as possible. However, accident shows that the driver is backwards up to 200mm, which causes his feet to slip off the

So we automatically apply the brakes 600 before the collision to prevent the car pushed into traffic or pedestrians and to minimise the forward on the occupants.

Lights tricks

Mercedes-Benz has only just its Adaptive High Beam on the E-Class, it is already pushing the further.

The existing system was with Continental and uses a rolling screen in concert infra-red cameras to pull the light cone gradually towards the light source and just ahead of the oncoming The new system swaps existing technology with semiconductor Emitting Diodes (LEDs) for the headlights. These automatically the light cone out of the eyes of drivers.

The ESF 2009’s headlights use 100 each and they can be lit up individually.

It works with the infra-red in a way the current system can’t: the camera picks up a pedestrian or in the dark, it repeatedly flashes the on the hazard to make sure you see it.

as Assistance and Safety Systems manager Dr Walter Zeigler it’s not without its development

We will have LEDs as the lights soon, but the only problem is cooling them.

We to keep the temperature at 120-130 They have a better than standard, but they produce heat and they to be cooled, even at a standstill, so need to be some sort of

Child Seat breakthrough

child seats are plastic, but the ESF uses a new, modular seat developed with specialist, Takata.

Suitable for from three to 12 years, the has been designed to restrain the head and shoulders, while the and width can be adapted to suit children.

It offers better and more stiffness with impacts than current Schöneburg insisted.


Mercedes-Benz plans to harness the of mobile phone area systems to warn other about ice, rain, problems, fog or dangerous situations. these systems, the ESF 2009 can communicate with other up to 500 metres away, while its classifies all the data to warn about the important bits.

But the ESF intelligent communications system is not an Benz feature. While the has been working on interactive for seven years, it is also with the rest of the German car to come up with a uniform standard.

It’s very for compatibility that we have a standard around the world, told the Carsales Network.

A involving 400 vehicles communicating each other is being in northern Germany currently and continue until 2012.

We different projects worldwide in and the US, and here in Germany. I hope in years we will have the cars with this on the road. And I hope then the will follow very Schöneburg opined.
