How does it work?
Advanced sensors measure vehicle speed and tilt and trigger airbag curtains to protect passengers when a vehicle starts to roll over
The Firestone tire recall in the USA has helped focus attention on rollover crashes
Sport-utilities and pickups will be the first vehicles to be equipped with rollover sensor systems. SUVs have a high center of gravity. The systems will later spread to luxury vehicles
Sweden's Autoliv is leading the development of commercial rollover protection applications. Several other suppliers, including Visteon, TRW and Siemens Automotive, are promoting their own systems
