FRANKFURT, Germany (Sept. 13, 2011)—Bridgestone Corp. has developed technology that can provide real-time road surface condition information to the driver through the tires.
The technology, based on a concept Bridgestone calls Contact Area Information Sensing, collects and evaluates road surface condition information through sensors in the tire communicating with the vehicle's analytical systems. The Japanese company said it is capable of sensing instantaneous vibration input data and digitalizing it by in-vehicle analysis equipment.
CAIS classifies the state of the road surface into seven conditions—dry, semi-dry, wet, slush, fresh snow, compacted snow, ice—and transmits this information directly to the driver through an in-car display, Bridgestone said.
Specifically, an accelerator sensor inside the tread detects vibrations in the tire's tread and sends that information wirelessly to the vehicle's analytical equipment. Moreover, CAIS is powered by Bridgestone's proprietary electromagnetic power generation equipment.
By providing immediate road surface information, CAIS aims to better prepare drivers for “rapid changes in dangerous driving conditions,” Bridgestone said.
The technology will be on display at the International Motor Show in Frankfurt Sept. 13-15 2011.
