Abstract
A system for monitoring deformations of a tire fitted on a rim associated with a vehicle includes a reflecting element positioned on an inner surface of the tire and a moving station located in a predetermined position on the rim. The reflecting element reflects an optical beam and includes a region having at least one area of high light reflection and at least one area of low light reflection. The moving station sends the optical beam toward the inner surface, receives one or more reflections of the optical beam from the inner surface or the reflecting element, and emits a signal proportional to the deformations of the tire in a longitudinal direction, in a transverse direction, and in a vertical direction.

A system for monitoring deformations of a moving tyre fitted on a rim associated with a vehicle, comprising:
- a reflecting element positioned on an inner surface of the tyre for reflecting an optical beam and comprising a region having at least one area of high light reflection and at least one area of low light reflection;
- and
- a moving station located in a predetermined position on the rim for sending the optical beam toward the inner surface, receiving one or more reflections of the optical beam from the inner surface or the reflecting element, and emitting a signal proportional to the deformations of the tyre in a longitudinal direction, in a transverse direction, and in a vertical direction.
A method for monitoring deformations of a moving tyre fitted on a rim associated with a vehicle, comprising the steps of:
- emitting a signal within the tyre from a predetermined position on the rim;
- reflecting the signal from an inner surface of the tyre or a reflecting element positioned on the inner surface, wherein the inner surface or the reflecting element comprises a region having at least one area of high light reflection and at least one area of low light reflection;
- receiving the reflected signal;
- and
- processing the received signal to generate a signal proportional to the deformations of the tyre in a longitudinal direction, in a transverse direction, and in a vertical direction.
A wheel for a vehicle, comprising:
- a tyre;
- a supporting rim;
- a moving station;
- and
- a reflecting element;
- wherein the tyre is fitted on the supporting rim,
- wherein the moving station is located at a predetermined position on the rim,
- wherein the moving station sends an optical beam toward an inner surface of the tyre, receives the optical beam reflected from the inner surface, and transmits a signal proportional to deformations of the tyre in a longitudinal direction, in a transverse direction, and in a vertical direction, and
- wherein the reflecting element reflects the optical beam and is positioned on the inner surface and comprises a region having at least one area of high light reflection and at least one area of low light reflection.
