Tyres that warn cars about the road
BRIDGESTONE has announced the second version of its Contact Area Information Sensing ( CAIS) system is finally ready for commercial application.
Bridgestone unveiled the first version of its CAIS technology at the Frankfurt Auto Show in 2011. Four years ago, the system relied on a strain sensor to calculate the load and side forces acting on the sidewalls of the tyre.
CAIS 2 followed in 2012 with an acceleration sensor that added road surface monitoring to the mix, and last year CAIS 3 introduced a sensors that could also monitor the rubber left on the tyre.
All the systems use Bridgestone’s proprietary electromagnetic generator, so there is no need to change batteries.
Bridgestone said CAIS 2 is now ready to be installed in cars and trucks.
The sensors in CAIS 2 monitors high frequency vibrations of the tyre and transmit these wirelessly to a central module housed inside the car that tells all vehicles in the area with Bridgestone tyres equipped with CAIS 2 what the road surface is like.
The company also plans to sell its CAIS 3 system in the near future, which will see the world’s first tyres that can tell drivers every aspect of the tyre’s interaction with the road, from the air pressure and tread depth to road conditions.
The latest tyres will inform drivers about every aspect of the tyre’s interaction with the road, from the air pressure and tread depth to road conditions.
