Starting from an acceleration signal, representative of a radial acceleration undergone by a portion of a crown region of said tyre due to the rolling of said tyre on a rolling surface, the trend of the first derivative of the radial acceleration is determined at a portion representative of the interaction of the tyre with a water layer. From the trend of the first derivative of the radial acceleration, it is determined at least one first parameter representative of an aquaplane condition of the tyre on the basis of a comparison between a first maximum and a second maximum of the first derivative at the portion representative of the interaction between tyre and water layer.

Abstract

Starting from an acceleration signal, representative of a radial acceleration undergone by a portion of a crown region of said tyre due to the rolling of said tyre on a rolling surface, the trend of the first derivative of the radial acceleration is determined at a portion representative of the interaction of the tyre with a water layer. From the trend of the first derivative of the radial acceleration, it is determined at least one first parameter representative of an aquaplane condition of the tyre on the basis of a comparison between a first maximum and a second maximum of the first derivative at the portion representative of the interaction between tyre and water layer.
