Method for determining the load condition of a vehicle
First Claim
1. A method for determining the load condition of a vehicle (60) moving at non-zero speed, the vehicle being equipped with a plurality of tire-wheel assemblies (41-42, 51-52) mounted on at least two axles and with devices enabling determination of the vehicle'"'"'s speed, the rotation frequencies or speeds and the actual inflation pressures of at least two tire-wheel assemblies mounted on two different axles, the method comprising the following stages:
- (A) determination of the inflation pressures and rotation frequencies of two tire-wheel assemblies mounted on two different axles;
(B) calculation of the load difference between the two tire-wheel assemblies from the vehicle'"'"'s speed and the rotation frequencies of the two tire-wheel assemblies, taking into account the actual inflation pressures;
(C) determination of the load condition by comparing the calculated load difference with at least one predetermined threshold.

8. A method for monitoring the inflation pressure of a first tire-wheel assembly of a vehicle (60) moving at non-zero speed, the vehicle being equipped with a plurality of tire-wheel assemblies (41-42, 51-52) mounted on at least two axles and with devices enabling determination of the vehicle'"'"'s speed, the rotation frequencies or speeds and the actual inflation pressures of at least two tire-wheel assemblies mounted on two different axles, the method comprising the following stages:
-
(A) determination of the inflation pressures and rotation frequencies of two tire- wheel assemblies mounted on two different axles; (B) calculation of the load difference between the two tire-wheel assemblies from the vehicle'"'"'s speed and the rotation frequencies of the two tire-wheel assemblies, taking into account the actual inflation pressures; (C) determination of the load condition by comparing the calculated load difference with at least one predetermined threshold; (D) determination of a lower threshold for the inflation pressure, appropriate for the load condition of the vehicle and for the position of the said first tire- wheel assembly on the vehicle; (E) determination of the inflation pressure of the said first tire-wheel assembly and alerting of the driver of the vehicle if the inflation pressure of the first tire-wheel assembly is below the said lower threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for adapting the inflation pressure of a first tire-wheel assembly (41-42, 51-52) of a vehicle (60) moving at non-zero speed, the vehicle being equipped with:
-
a plurality of tire-wheel assemblies mounted on at least two axles, devices enabling determination of the vehicle'"'"'s speed, the rotation frequencies or speeds and the actual inflation pressures of at least two tire-wheel assemblies mounted on two different axles, and a device which enables the inflation pressure of the said first tire-wheel assembly to be modified, the method comprising the following stages; (A) determination of the inflation pressures and rotation frequencies of two tire-wheel assemblies mounted on two different axles; (B) calculation of the load difference between the two tire-wheel assemblies from the vehicle'"'"'s speed and the rotation frequencies of the two tire-wheel assemblies, taking into account the actual inflation pressures; (C) determination of the load condition by comparing the calculated load difference with at least one predetermined threshold; (D) determination of a lower threshold for the inflation pressure, appropriate for the load condition of the vehicle and for the position of the said first tire-wheel assembly on the vehicle; (E) determination of the inflation pressure of the said first tire-wheel assembly and increase of that inflation pressure if it is below the said lower threshold. - View Dependent Claims (16, 17, 18, 19, 20, 21)
