DETECTION OF REVOLUTIONS OF A TYRE AND WHEEL ASSEMBLY BY MEANS OF THE EARTH MAGNETIC FIELD

摘要

The device has a passive sensor (10), and an interpreter device linked to the sensor for interpreting the signals produced by the sensor. The sensor is integrated to a pneumatic tire and wheel assembly (14) of a vehicle (2) such that rotation of the assembly corresponds to the rotation of the sensors. The sensor produces signals that are proportional to the temporal variation of a magnetic flux. Independent claims are also included for the following: (a) a wheel equipped of a device for detecting the rotations of the wheel (b) a pneumatic tire equipped of a device for detecting the rotation of the tire (c) a process for detecting the rotations of a pneumatic tire and wheel assembly.
