  • Patent number: 11090985
    Abstract: The invention relates to a method and an apparatus for determination of the wear on at least one tire of a vehicle, wherein the vehicle has a tire pressure monitoring system, consisting of a pressure sensor, a transmission unit and a reception unit, as well as a computer unit and a data memory having a database. Proceeding from a circumference of the tire (5) defined by the tire manufacturer and thereby a mantle surface having a length L=2?r, wherein r is the radius of the tire (5), the radius decreases during corresponding wear, and thereby the length of the mantle surface also decreases. The length of the flat pattern of a new tire is therefore greater, in terms of length, than the length of the flat pattern of a used tire. This is determined by a sensor (4), the value of which is transmitted by a first module (2) to a second module (3), which is fixed in place. There, the value L is calculated and compared with data in a database and evaluated.

The vibration detector outputs a detection signal according to amplitude of a vibration of the tire. The signal processor extracts a ground contact section during which the portion of the tread provided with the vibration sensor is in contact with the ground, from the detection signal, and generates a road surface data based on the detection signal during the ground contact section. The transmitter transmits the road surface data. The activation controller starts an activation of the signal processor at a time in association with the ground contact starting time at which the portion of the tread provided with the vibration detector begins to be in contact with the ground.
