Pneumatic tire and wheel assembly rotation detecting device for use in motor vehicle, has passive sensor integrated to assembly, where signals produced by sensor are proportional to temporal variation of magnetic flux

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.
