Everyone tells you: it is essential to check the pressure of your tires at least once a month. More often if you live in a place where temperatures vary from day to day. A situation that we Canadians know well. But now Continental could have the solution: the adaptive tire.
The principle is relatively simple: the tire is equipped with sensors, as it is already the case of the tires having a pressure monitor. This time, however, the sensors are paired with a pump located in the center of the tire. When the sensors detect a change in air pressure in the tire, the pump sends a little air to balance the whole thing. It can compress the air in the tire during accelerations in order to have an optimal pressure.
The excess air generated is stored in an internal tank. It can be used to inflate the tire under special conditions. All this is managed by an electronic system also monitoring the tire temperature, wear and the possibility of damage to the rubber.
The tire, called CARE (for Connected, Autonomous, Reliable) is for the moment only at the prototype stage. It is designed to equip autonomous cars, and require less supervision. The actual cost of such a system is unknown at the moment, but it can be imagined quite high, taking into account embedded technology.
Another detail, because autonomous cars will also be electric cars, Continental’s self-adaptive wheels have been manufactured to minimize vibration and reduce friction to maximize energy savings.
The idea is great. Only have to see when it will be marketed! And then finished the monthly checks!
