Patent ID: 7658099

Claim:
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.
