In November 2018, ZF offered the world’s first exterior airbag and since then the corporate has additional perfected the know-how to deliver it nearer to manufacturing.
We now get to see it in motion for the primary time as ZF gave a dwell demonstration of the prototype for the pre-crash exterior aspect airbag system in Memmingen, Germany. In line with the corporate, side-impact collisions are among the many most harmful sort of highway visitors accidents. In Germany alone, they account for almost 700 deaths per 12 months, almost a 3rd of all occupant fatalities.

The auto components provider believes its new pre-crash security system prototype it developed will help save lives and cut back occupant harm severity by as much as 40 p.c. That’s as a result of the exterior airbag is claimed to cut back the penetration of the intruding car by as much as 30 p.c.
The prototype makes use of an exterior aspect airbag deployed milliseconds earlier than a collision to offer an extra lateral crumple zone. To be able to make it work, ZF has networked the airbags to the car’s sensor methods and “developed algorithms which can be able to figuring out if a crash is imminent and resolve whether or not or to not deploy the airbag.”
Unsurprisingly, the most important problem ZF confronted when creating this technique was easy methods to reliably acknowledge an unavoidable collision and deploy the exterior aspect airbag earlier than the collision takes place. The system solely has roughly 150 milliseconds to make the choice to deploy the airbag and fill it — that’s the time it takes an individual to blink.
One other problem is the truth that the airbag has a capability of between 280 and 400 liters, 5 to eight instances the amount of a driver airbag. Meaning it takes extra time to fill it.
Utilizing linked cameras, radar and lidar, the system is ready to establish a possible influence, with algorithms throughout the software program deciding whether or not or not a collision is unavoidable and the deployment of the airbag is each attainable and helpful. If all these choices are affirmative, the system ignites the inflators to fill the airbag which expands upwards from the aspect sill to type an extra crumple zone within the door space between the A and C pillars.
Within the video, ZF’s exterior airbag appears to work advantageous however the demonstration would have most likely been extra telling if the corporate used an precise automotive as a substitute of a seemingly frail rig to t-bone its exterior airbag-equipped automotive.
