Monitoring of a tire by acceleration measurement
First Claim
1. Process for the in-service monitoring of the condition of a tire (1) of a wheel, characterized by the steps consisting in:
- providing in the tire (1), near the tread (10), a miniature sensor (4), sensitive to the acceleration (γ
), and monitoring the variations in the measurement from this sensor (4), the measurements made in the zone (BC) where the tread is in contact with the ground being related to the size of this zone (BC) and, thereby, to the condition of the tire (1).

Abstract
The invention relates to the in-service monitoring of the condition of a tire of a wheel of a vehicle. To this end it proposes a process and, in particular, a device comprising: a sensor (4) mounted on the wheel, coupling means (BVF2, BRF2) for transmitting to the vehicle indications derived from this sensor (4), and electrical energizing means (BVF1, BRF1). According to the invention, the sensor (4) is a miniature acceleration-sensitive sensor implanted in the tread of the tire or in the vicinity of the tread. The coupling means, mounted on the wheel, then transmit indications relating to the measurements made at the moment at which the tread is in contact with the ground.

11. Device for the in-service monitoring of the condition of a tire (1) of a wheel of a vehicle, of the type comprising:
-
a sensor (4) mounted on the wheel, coupling means (BVF2, BRF2) for transmitting to the vehicle indications derived from this sensor (4), and electrical energizing means (SVF1, BVF1, BRF1), characterized in that the sensor (4) is a miniature sensor sensitive to the acceleration (γ
), implanted in the tread (10) of the tire (1) or in the vicinity of the tread, and in that the coupling means, mounted on the wheel, transmit indications (TL, Tp) relating to the measurements made at the moment at which the tread (10) is in contact with the ground. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
