Abstract:
1. A system for determining a load exerted on a tyre, fitted on a vehicle, during running of the vehicle on a rolling surface, the system comprising: a measuring device; a pressure sensor; a device for estimating a rotation speed of the tyre; and at least one processing unit; wherein the measuring device is adapted to acquire a signal representative of a deformation to which a first tread area portion of the tyre is subjected during passage of the first tread area portion through a contact region between the tyre and the rolling surface, wherein the pressure sensor is adapted to sense an inflation pressure of the tyre, wherein the at least one processing unit is adapted to determine an amplitude of a radial deformation in a first portion of the signal, and wherein the at least one processing unit also is adapted to derive the load exerted on the tyre from the rotation speed, the inflation pressure, and the amplitude.
