Abstract

A vehicle comprising at least one mounted assembly, comprising a wheel and a tire, and an element consisting partially of polymer compounds, said mounted assembly comprising at least one wireless system for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology, at least one area of said element being at a constant distance from the mounted assembly during use of the vehicle. An interrogation antenna is associated with said area of said element.

Claims

1. A vehicle comprising at least one mounted assembly, comprising a wheel and a tire, and an element formed partially of polymer compounds, said mounted assembly comprising at least one wireless system for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology, at least one area of said element being at a constant distance from the mounted assembly during use of the vehicle, wherein an interrogation antenna is associated with said at least one area of said element, and said at least one area of said element is at a distance of less than 10 cm from the mounted assembly during use of the vehicle, wherein at least two wireless systems for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology, comprising linearly polarized antennae, are associated with the mounted assembly, wherein the polarization directions of the antennae of the measuring systems form therebetween an angle of between 30 and 90°

, and wherein the polarization directions of the interrogation antennae form therebetween an angle of between 30 and 90°

.

2. The vehicle according to claim 1, wherein the interrogation antenna is fixed to said at least one area.

3. The vehicle according to claim 1, wherein the interrogation antenna is buried in said at least one area.

4. The vehicle according to claim 1, wherein the element, formed partially of polymer compounds, is fixed to the axis of the wheel.

5. The vehicle according to claim 1, wherein at least one wireless system for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology is incorporated in a tire.

6. The vehicle according to claim 5, wherein at least one measuring system is buried in a part of the tread of the tire.

7. The vehicle according to claim 5, wherein at least one measuring system is buried in a part of the sidewall of the tire.

8. The vehicle according to claim 5, wherein at least one measuring system is buried in a part of a bead of the tire.

9. A vehicle comprising at least one mounted assembly, comprising a wheel and a tire, and an element formed partially of polymer compounds, said mounted assembly comprising at least one wireless system for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology, at least one area of said element being at a constant distance from the mounted assembly during use of the vehicle, wherein an interrogation antenna is associated with said at least one area of said element, and said at least one area of said element is at a distance of less than 10 cm from the mounted assembly during use of the vehicle, wherein at least two wireless systems for measuring a physical parameter of the tire by surface acoustic wave technology or volume acoustic wave technology, comprising linearly polarized antenna, are associated with the mounted assembly, and wherein the polarization directions of the antennae of the measuring systems are parallel with one another.
