Abstract
The present invention relates to an autonomous device which is intended to be carried by a tire and wheel assembly in order to detect revolutions of said assembly, comprising at least one sensor which produces signals and an interpreter device which is connected to the sensor in order to interpret the signals produced by the sensor. The sensor is a passive sensor, the produced signals of which are proportional to the temporal variations of a magnetic flux though this sensor, and is intended to be integral in rotation with the tire such that the revolutions of said assembly correspond to the revolutions of said sensor. The invention likewise relates to an assembly provided with an autonomous device which permits detection of revolutions of the assembly, and a method for detecting revolutions of the assembly.
