Calibration method and system of a sensor for tyres

Abstract

Calibration method (), and related system (), of a sensor () for tyres, comprising, with the sensor () mounted at a crown portion () of a tyre () and during an advancement of a vehicle onto which the tyre () is fitted: a) acquiring (), from the sensor (), a motion signal representative of a motion of the crown portion (); b) acquiring () a respective current value of one or more operating conditions of the tyre (); c) processing () the motion signal for obtaining from the motion signal a first value representative of a calibration physical quantity associated with the motion of the crown portion () at said respective current value of the one or more operating conditions; d) calculating () a second value representative of the calibration physical quantity at the respective current value of the one or more operating conditions, by a predetermined mathematical correlation between the calibration physical quantity and the one or more operating conditions; e) iterating steps a), b), c) and d) for obtaining a first set of first values representative of the calibration physical quantity varying the respective current value of the one or more operating conditions, and a corresponding second set of second values representative of the calibration physical quantity; f) calibrating () the sensor () by a comparison between the first and second set.
