Abstract
A method for wear control of vehicle tyres, includes: detecting deformation of an inner surface of a first tyre by means of a first sensor; determining a first level of wear of the first tyre; detecting a deformation of an inner surface of a second tyre by means of a second sensor; determining a second level of wear of the second tyre; 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 tyres, a method of determining the wear of a tyre and a system for determining the wear of a tyre.

54. A method of controlling wear in a vehicle tyre, comprising:
-
detecting a deformation of an inner surface of a first tyre fitted on a vehicle, by means of a first sensor fitted inside said first tyre; determining a first level of wear of the first tyre depending on a detection carried out by said first sensor; detecting a deformation of an inner surface of a second tyre fitted on said vehicle, by means of a second sensor fitted inside said second tyre; determining a second level of wear of the second tyre depending on a detection carried out by said second sensor; comparing said first and second levels of wear with each other; and generating a notification signal representative of said comparison. - View Dependent Claims (55, 56)

57. A method of determining wear of a tyre, wherein said tyre rolls on a rolling surface, a footprint area being defined between the tyre and said rolling surface, comprising:
-
identifying a detection region which is external and substantially contiguous to the footprint area; detecting a first signal representative of a deformation of an inner surface of the tyre, said first signal comprising at least one first portion representative of said deformation in the detection region; and processing at least said first portion of said first signal so as to determine at least one parameter representative of the wear of said tyre. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79)

80. A system for controlling wear in vehicle tyres, comprising:
-
at least one first sensor capable of being adapted to be fitted inside a first tyre of said vehicle, and to detect a first wear level of said first tyre; at least one second sensor capable of being fitted inside a second tyre of said vehicle, and detecting a second wear level of said second tyre; and at least one control unit provided with; at least one processing module operatively associated with said first and second sensors, said at least one processing module capable of being adapted to determine a first wear level of said first tyre as a function of detection of said first sensor, and a second wear level of said second tyre as a function of detection of said second sensor; a comparison module capable of being adapted to compare said first and second wear levels with each other; and a signalling module capable of being adapted to generate a notification signal representative of said comparison. - View Dependent Claims (81, 82)

83. A system for determining a parameter representative of wear of a tyre, comprising:
-
a tyre adapted to roll on a rolling surface so as to define a footprint area between the tyre and said rolling surface, and a detection region that is external and substantially contiguous to the footprint area; at least one sensor fitted on an inner surface of said tyre for detecting at least one first signal representative of a deformation of said inner surface of the tyre, said first signal comprising at least one first portion representative of said deformation in the detection region; and a processing unit operatively associated with said sensor for receiving said first signal and capable of being adapted to process at least said first portion of said first signal so as to determine at least one parameter representative of the wear of said tyre. - View Dependent Claims (84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106)
