AIS Systems On Tires

(Contact Area Information Sensing The - Cais) is a system that includes sensors mounted inside the tire, in order to provide accurate information about the state of the road surface, thereby alerting the driver control means stars be suitable.

Bridgestone first introduced this technology at the Frankfurt Auto Show 2011 exhibition, the first version uses a sensor used to calculate the weight and forces affecting the tire. Cais later version 2 was launched and additional acceleration sensor can determine the road conditions. In 2014, the next upgrade is Cais 3 is formed, evolved into a system that can monitor tire wear.

This system is mainly used for car tires and truck tires

Used mainly for car and truck tires, Cais works by a single generator. Its mission is to monitor the frequency of vibration of the tire and passing through the analysis provided in the car, through a wireless connection. This data is then "translated" into the information indicating the actual road surface conditions, including dry, slightly dry, wet, slippery, snow and ice. Then, this information is transmitted to the display, gives the driver know the status of the road they are passing.Japanese manufacturer said that this feature is only useful as a first step. In the future, their plan is to make that information is shared for the following car. This of course does not have to completely rely on Bridgestone, but also depend on an infrastructure wider communication, including roads and vehicle traffic on it. Known intelligent transport systems has been developed so many years in Japan, Europe and the United States. Therefore, starting with Bridgestone obviously better than competitors.Expected in the near future, Cais 3 will be officially launched cungcam tire pressure variations. Meanwhile, Bridgestone not only provide customers with a conventional tire, as it was possible for them to know every aspect of the interaction of tire and road surface, including: pressure, wear and road conditions.
