The system provides an alert whenever the inflation pressure drops significantly in relation to the pressure in another tire. In the event of a pressure loss, the rolling radius and therefore the rotation speed of the wheels change. This change is detected and is reported as a flat tire. Functional requirement In order to assure the reliable reporting of a flat tire, the system must be initialized for the correct tire inflation pressure. The initialization must be repeated after each time the tire inflation pressure is corrected and after every tire or wheel change.< 3.
