Mercedes-Benz’s ESF2009 Experimental Vehicle showcases safety of the future

The Mercedes-Benz ESF2009

Mercedes-Benz produced its last demonstrator car back in 1974, it exotic new technology like head restraints and seatbelt — things which become almost ubiquitous on new 30 years down the track. So worth taking a good at some of the wild and crazy on Benz’s ESF2009 Experimental Vehicle if you want to see where thinks road safety is in the next few decades. How about multi-zone headlights that dip only the LEDs shining at oncoming cars? Or inflatable structures that pop up for extra in a crash? What about a inflatable braking airbag pops out under the car to provide a high-traction contact patch and your braking power in an crash? Amazing stuff, and more.

Mercedes-Benz’s ESF2009 Safety Vehicle is the firm’s concept car, and one focused on road safety. The list of new innovations on this beast is astounding — quite the if you think you’ve seen it all Here goes.

Braking Bag

the car’s sensors detect an imminent collision, the braking bag is It’s a huge airbag a high-friction coating that out between the axles of the car, and as a massive braking contact to produce a huge decelerative that tires alone match.

The total deceleration power of a performance sports car is about 1G the braking bag would more double that stopping as it lifts the wheels up to 8cm off the ground. at 2G deceleration, you could come to a stop from 72kmh in one — then, presumably, the next five minutes around trying to find eyeballs.

Because you’re on an air cushion when you hit whatever is in of you, the braking bag also like an extra crumple dissipating some crash It’s also set up to substantially braking dive so that if hitting another vehicle, the isn’t down; the car is optimally for impact.

PRE-SAFE inflatable structures

Still in its infancy, one’s all about metal that stay folded during normal driving, but out and provide greatly improved in the event of a crash. The PRE-SAFE structures can either be activated to imminent collision information the collision detection systems or, in the of shields mounted further the car, around the seats and cross-members, they can be triggered by the itself.

The inflatable structures in the don’t yet have the ability to — so the pre-collision sensors had be pretty accurate.

Partial Main Beam headlights and spotlights

When attacking a dark country at night, there’s a few moments of vulnerability as you dip your headlights and try to on your side of the road, being blinded by oncoming Mercedes is trying to do away these moments using its Partial Main Beam

The headlamps are made up of 100 individually LEDs. An infrared camera oncoming traffic when got your brights on, and then only the LEDs that are directly at that vehicle. The is that, while you’re not the oncoming driver, the rest of the is fully illuminated.

The partial beam sensor also as a kind of spotlight when using your low-beam around town; if the infrared detect, for example, a pedestrian or in front of you, the Partial Beam system can spotlight potential hazard in bright calling your attention to it, as as alerting the pedestrian to your Very smart.

Interactive communication

Mercedes believes one car’s collision detection report should be of use to all other users too — so if your pick up a hazard, it’s so that other cars similar systems can pick it up in advance.

The initial system broadcasts than 500 meters, but Benz that roadside broadcast and oncoming traffic will the signal significantly further. amusing to note that the is designed to pick up police and highlight them as a hazard not a bad idea.

The vehicle communication is being tested using up to 400 from Mercedes-Benz and other manufacturers. Testing started in and will continue until The company predicts that a coverage network of real-time information will become when about 10 percent of carry the system.

PRE-SAFE — moving passengers to during a collision

When zones, airbags, side-impact protection and other systems in to protect a car’s occupants in a millimeters can make all the difference injury and fatality.

The idea of the Pulse system is to fire air in the seats during a collision, the occupants in towards the safer of the car, with a firm in the ribs. The force of this is determined by things like acceleration, steering angle and — and the system is designed to put you up to further away from the when it hits.

Child Cam

Mercedes clearly that kids mucking in the back seat — and turning around to see what up to and give them a mouthful for it are a significant road safety

So they’ve mounted a Child Cam in the area that can display photos — not video, would be distracting — of the kids are up to in the back on the LCD dash So you’ve genuinely got eyes in the of your head to work out pulling whose hair or who has out of their seatbelt.

When there’s more one person in a car, the other can become a serious safety in a crash — take a impact, in which the back passengers might well be by seatbelts. The passenger often the impact coming and tries to away from it — and motion, combined with the can cause passengers to knock heads together in a devastating headbutt.

Mercedes attempts to this issue in the ESF2009 an inter-seat airbag system inflates soft barriers passengers as the crash happens, each person from the and cushioning the movement of all bodies in the car

The Belt-Bag inflating seatbelt

have already saved lives, and they remain the source of protection in collisions, to backseat passengers who don’t get an airbag.

The ESF2009’s Belt-Bag is one of the ones most likely to it to a production Benz in the near As the name suggests, it’s an seatbelt that’s triggered in a

The Belt-Bag unfolds as it inflates, doubling its surface contact the wearer to distribute its restraining across a wider section of the as well as contributing an air cushioning Very nifty.

Size-adaptive airbags

It makes sense if you about it — a tall with the seat right is going to need a bigger than a small one whose is much closer to the dash. So the gurus at Mercedes have a system that adjusts the timing and the amount of air injected the airbag depending on who’s in it.

The system takes weight, position and other information account to determine how big the airbag to be; a standard airbag inflates to 120 liters, but the ESF2009’s adaptive can go between 90 and 150 liters, controlled by adjusting retainer bands.

The PRE-SAFE demonstrator

This is all nifty technology — but in an world, none of us would get to see it in action. That’s why Mercedes has put a demonstrator vehicle which be trollied out at major auto starting at this year’s ESV in Stuttgart.

Passengers can sit in the cabin, a version of an S-Class saloon, is accelerated on a linear drive to 16kmh, and then crashed a hydraulic shock absorber to the safety systems inside. It can be at any angle up to 30 degrees, and can also rear-end collisions or be set sideways to the effect of high-G cornering.

road trauma fatalities more than a million a year worldwide, it’s to see Mercedes taking a leading in developing and publicizing these of safety systems. There’s great ideas in this vehicle, and we’d love to see on the road before too long.
