The German carmaker Mercedes-Benz has come up with the ESF 2009 which was patterned after the S400 Hybrid to showcase some of its latest safety innovations. A pioneer in car safety, Mercedes once again proved itself with the ESF 2009 which is equipped with 13 safety advancements which are completely functional even in just demonstration form.
The PRE-SAFE Structure, as one of the most remarkable element of the experimental car, is a collapsed metal beam structure in a folded state and which is activated via an internal pressure of 145 to 290 psi generated by a gas generator when a collision is impending.
Additional protection is provided when the metal sections unfold. A further safety innovation that comes with the car is an external air bag located underneath the car and designated as a braking bag.
It functions as a secondary brake that deploys just prior to a collision when an onboard sensor system detects that an impact cannot be avoided. When the braking bag is deployed it makes contact with the ground surface to provide extra friction to slow down the vehicle and raises the car up to 8 cm to counteract dive effect that result from hard braking.
Furthermore, geometrical compatibility with the other vehicle in the mishap is enhanced. The experimental car also comes with a special technology known as Interactive Vehicle Communication which is able to communicate with other cars or relay stations by sending and receiving bad weather warnings or road obstacles that may prove hazardous.
Another safety feature in the ESF 2009 is the PRE-SAFE Pulse which lowers the forces that act against the torsos of the passengers in instances of a lateral collision by moving the occupants about 5 cm toward the center of the vehicle as a safety measure.
This is achieved by inflating the air chambers located in the side bolsters of the seats. Other intelligent safety features that are included in the ESF 2009 include partial main beam headlights, Size Adaptive Airbags, and a Hybrid Battery Shield. The Mercedes Benz experimental car will be introduced this coming June 15, Monday, at the Conference on Enhanced Safety of Vehicles.
