Method and system for wear control of vehicle tyres

摘要

A method for wear control of vehicle tires, includes: detecting deformation of an inner surface of a first tire by means of a first sensor; determining a first level of wear of the first tire; detecting a deformation of an inner surface of a second tire by means of a second sensor; determining a second level of wear of the second tire; comparing the first and second levels of wear with each other; and generating a notification signal representative of the comparison. Also disclosed is a system for wear control of vehicle tires, a method of determining the wear of a tire and a system for determining the wear of a tire.

主权项

1. A method of determining wear of a tyre using a processing unit, wherein said tyre rolls on a rolling surface, a footprint area being defined between the tyre and said rolling surface, the method comprising:
detecting a first signal representative of a deformation of an inner surface of the tyre; identifying at least one first portion comprised within said first signal using the processing unit, said first portion being representative of said deformation in a detection region which is external to the footprint area and substantially contiguous to the footprint area in the rotation direction of the tyre; and processing at least said first portion of said first signal using the processing unit so as to determine at least one parameter representative of the wear of said tyre, wherein said comprises filtering said first signal in a first frequency band in the range of between 700 Hz and 2000 Hz.
