Title: METHOD AND DEVICE FOR DETECTING THE WEAR ON AT LEAST ONE TYRE OF A VEHICLE
Abstract:
The invention relates to a method and to a device for detecting the wear on at least one tyre of a vehicle, wherein the vehicle has a tyre pressure control system composed of a pressure sensor, a transceiver unit and a computer unit and a data memory with a database. Starting from a circumference of the tyre (5) defined by the tyre manufacturer, and therefore a lateral face with a length L=2πr, wherein r is the radius of the tyre (5), the radius decreases, and therefore the length of the lateral face decreases, as the tyre is correspondingly used. The length of the developed view of a new tyre is therefore greater in terms of length than the length of the developed view of a used tyre. This is detected by a sensor (4) whose value is transmitted from a first assembly (2) to a second positionally fixed assembly (3). The value L is calculated there and compared with data in a database and evaluated.
