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, characterized in that the polarization directions of the antennas make an angle of between 30 and 90°

between them.

2. The ground-contacting component of a vehicle as claimed in claim 1, when said ground-contacting component consists partly of polymeric compounds, characterized in that at least one measurement system is embedded in a polymeric compound.

3. The ground-contacting component of a vehicle as claimed in claim 1, characterized in that the 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, characterized in that the measurement systems are identical.

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

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

7. The ground-contacting component of a vehicle as claimed in claim 1, which is a constituent of a mounted assembly comprising a wheel, a tire and a support member for supporting the tire in particular for use in degraded mode, characterized in that the 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, the base of which is 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 consisting partly of rubber compounds, said tire comprising at least two physical parameter measurement systems, each having linearly polarized antennas, characterized in that the polarization directions of the antennas make an angle of between 30 and 90°

between them.

9. The tire as claimed in claim 8, characterized in that the systems are embedded in at least one rubber compound.

10. The tire as claimed in claim 8, characterized in that the systems are wireless measurement systems based on surface acoustic wave or bulk acoustic wave technology.

11. The tire as claimed in claim 8, characterized in that the measurement systems are identical.

12. The tire as claimed in claim 8, characterized in that at least one measurement system is embedded in a part of the tread.

13. The tire as claimed in claim 8, characterized in that at least one measurement system is embedded in a part of the axially outer ends of the tread.

14. The tire as claimed in claim 8, characterized in that at least one measurement system is embedded in a part of a sidewall.

15. The tire as claimed in claim 8, characterized in that at least one measurement system is embedded in a part of a bead.

16. A vehicle ground contact, comprising at least two elements, with at least two of said elements comprising at least one physical parameter measurement system, each measurement system having a linearly polarized antenna, characterized in that the polarization directions of the antennas make an angle of between 30 and 90°

between them.

17. The vehicle ground contact as claimed in claim 16, at least one of said two elements consisting partly of polymeric compounds, characterized in that at least one measurement system is embedded in a polymeric compound.

18. The vehicle ground contact as claimed in claim 16, characterized in that the 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, characterized in that the measurement systems are identical.
