The Contact Area Information Sensing (CAIS) is a system consisting of a sensor built into the tire to provide accurate information about the condition of the road, thus alerting Drivers control vehicles accordingly. Developed in 2011, CAIS is now ready for commercial applications.
Bridgestone first introduced the technology at the Frankfurt Auto Show 2011, the first version to use a sensor to calculate the weight and impact on the tire. The CAIS 2 version was later introduced and added an accelerometer that can determine the pavement condition. In 2014, the next upgrade was CAIS 3, which developed into a system that can track tire wear . At present, the sample available for commercialization is CAIS 2 .
This tire is mainly used for car tires and trucks.
Used primarily for truck and truck tires, CAIS operates on a single generator. Its mission is to monitor the vibration frequency of the tire and then pass it through the analyzer in the car, via a wireless connection. This data is then translated into information describing actual pavement conditions, including dry, wet, dry, slippery, snow and ice. Then, this information is transmitted to the screen, which gives the driver the status of the road they are passing through.
Japanese manufacturers say that this useful feature is only the first step. In the future, their plan is to make the information shared for later vehicles. This, of course, is not entirely about Bridgestone, but depends on a broader communications infrastructure, including roads and means of transport. It is known that such intelligent transportation systems have been developed over the years in Japan, Europe and the United States. Therefore, Bridgestone clearly has a better start than its competitors.
It is expected that in the near future, CAIS 3 will be officially launched on the market with tire pressure sensor . Bridgestone does not just provide the consumer with a regular tire, it also gives them the ability to know every aspect of tire and pavement interactions, including: pressure, wear and tread. road accidents.
