Abstract

A ground-contacting component of a vehicle, comprising at least two physical parameter measurement systems, each measurement system having a linearly polarized antenna. The polarization directions of the antennas make an angle of between 30 and 90° between them. Also disclosed are a tire and a vehicle ground contact.

Claims

1. A ground-contacting component of a vehicle, comprising:

at least two physical parameter measurement systems, each measurement system having a linearly polarized antenna, the angles of the polarization directions of the antennas together forming a total angle that is between 30 and 90°

between the polarization directions of the antennas.

2. The ground-contacting component of a vehicle as claimed in claim 1, wherein said ground-contacting component comprises polymeric compounds, and wherein at least one measurement system is embedded in a polymeric compound.

3. The ground-contacting component of a vehicle as claimed in claim 1, wherein the at least two physical parameter measurement systems are wireless measurement systems based on surface acoustic wave or bulk acoustic wave technology.

4. The ground-contacting component of a vehicle as claimed in claim 1, wherein the at least two physical parameter measurement systems are identical.

5. The ground-contacting component of a vehicle as claimed in claim 1, is a constituent part of a mounted assembly comprising a wheel and a tire, wherein the ground-contacting component is part of the wheel.

6. The ground-contacting component of a vehicle as claimed in claim 1, is a constituent part of a mounted assembly comprising a wheel and a tire, wherein the ground-contacting component is part of the tire.

7. The ground-contacting component of a vehicle as claimed in claim 1, is a constituent part of a mounted assembly comprising a wheel, a tire, and a support member for supporting the tire, wherein the ground-contacting component is part of the support member.

8. A tire, comprising:

at least one carcass reinforcement structure formed from reinforcing elements and anchored on each side of the tire to a bead, having a base intended to be mounted on a rim seat, each bead being radially outwardly extended by a sidewall, the sidewalls radially outwardly joining a tread, the beads, the sidewalls, and the tread comprising rubber compounds, and

at least two physical parameter measurement systems, each having linearly polarized antennas, the angles of the polarization directions of the antennas together forming a total angle that is between 30 and 90°

between the polarization directions of the antennas.

9. The tire as claimed in claim 8, wherein the at least two physical parameter measurement systems are embedded in at least one rubber compound.

10. The tire as claimed in claim 8, wherein the at least two physical parameter measurement systems are wireless measurement systems based on surface acoustic wave or bulk acoustic wave technology.

11. The tire as claimed in claim 8, wherein the at least two physical parameter measurement systems are identical.

12. The tire as claimed in claim 8, wherein at least one of the at least two physical parameter measurement systems is embedded in a part of the tread.

13. The tire as claimed in claim 8, wherein at least one of the at least two physical parameter measurement systems is embedded in a part of the axially outer ends of the tread.

14. The tire as claimed in claim 8, wherein at least one of the at least two physical parameter measurement systems is embedded in a part of a sidewall.

15. The tire as claimed in claim 8, wherein at least one of the at least two physical parameter measurement systems is embedded in a part of a bead.

16. A vehicle ground contact, comprising:

at least two elements each comprising at least one physical parameter measurement system, each measurement system having a linearly polarized antenna, the angles of the polarization directions of the antennas together forming a total angle that is between 30 and 90°

between the polarization directions of the antennas.

17. The vehicle ground contact as claimed in claim 16, at least one of said two elements consisting partly of polymeric compounds, wherein at least one of the at least two physical parameter measurement systems is embedded in a polymeric compound.

18. The vehicle ground contact as claimed in claim 16, wherein the at least two physical parameter measurement systems are wireless measurement systems based on surface acoustic wave or bulk acoustic wave technology.

19. The vehicle ground contact as claimed in claim 16, wherein the at least two physical parameter measurement systems are identical.
