SEOUL -- South Korea's Hyundai auto group developed the world’s first multi-collision airbag system that significantly improves airbag performance by providing secondary protection following a primary impact.

Hyundai said Monday that the new airbag system allows airbags to deploy effectively upon a secondary impact by calibrating the status of the vehicle and occupants in a multi-collision accident.

In multi-collision accidents, the primary impact is followed by collisions with secondary objects such as trees, electrical posts or other vehicles. Statistics by the National Automotive Sampling System Crashworthiness Data System in the United States, about 30 percent of 56,000 vehicle accidents from 2000 to 2012 in North America involved multi-collisions.

The leading type of multi-collision accidents involved cars crossing over the center line, followed by collisions caused by a sudden stop at highway tollgates and highway median strip collisions.

"By improving airbag performance in multi-collision scenarios, we expect to significantly improve the safety of our drivers and passengers," Chi Tae-soo, who heads Hyundai's chassis technology center, said in a statement. 

Te multi-collision airbag system deploys fast when the initial safety system may not be effective, providing additional safety, Hyundai said, adding it responds more promptly during the secondary impact by recalibrating the collision intensity required for deployment.
