Hyundai is claiming a world first for its multi-collision airbag system
Hyundai Motor Group has announced the development and future availability in its Hyundai and Kia cars of the (claimed) world's first multi-collision airbag system that significantly improves performance in multi-collision accidents. Multi-collision accidents are those in which the primary impact is followed by collisions with secondary objects, such as trees, electrical posts or other vehicles, which occurs in three out of every 10 accidents.
Current airbag systems do not offer secondary protection when the initial impact is insufficient to cause them to deploy. However, the multi-collision airbag system allows airbags to deploy effectively upon a secondary impact by calibrating the status of the vehicle and the occupants.
The new technology detects occupant position in the cabin following an initial collision. When occupants are forced into unusual positions, the effectiveness of existing safety technology may be compromised. Multi-collision airbag systems are designed to deploy even faster when initial safety systems may not be effective, providing additional safety when drivers and passengers are most vulnerable. By recalibrating the collision intensity required for deployment, the airbag system responds more promptly during the secondary impact, thereby improving the safety of multi-collision vehicle occupants.
"By improving airbag performance in multi-collision scenarios, we expect to significantly improve the safety of our drivers and passengers," said Taesoo Chi, head of HMG's Chassis Technology Centre.
According to statistics by the National Automotive Sampling System Crashworthiness Data System (NASS-CDS), an office of the National Highway Traffic Safety Administration (NHTSA) in the US, about 30% of 56,000 vehicle accidents from 2000 to 2012 in the North American region involved multi-collisions.
The leading type of multi-collision accidents involved cars crossing over the centre line (30.8%), followed by collisions caused by a sudden stop at highway tollgates (13.5%), highway median strip collisions (8.0%), and sideswiping and collision with trees and electric poles (4.0%).
Hyundai Motor Group analysed multi-collision scenarios in multilateral ways to improve airbag performance and precision in secondary collisions and will introduce the system in future Hyundai and Kia vehicles.
