Abstract
A system for determining interaction between a tyre and a contact surface during movement of a motor vehicle includes at least one first sensor and processing means. The at least one first sensor includes one or more first elongated piezoelectric elements which extend along at least a first portion of the tyre. The at least one first sensor supplies a first signal to the processing means. The first signal is generated by rotation of the tyre and is generated cyclically with each revolution of the tyre. The processing means detects variations in time intervals between distinctive elements of the first signal. A tyre including the system, a kit for detecting behaviour of a tyre moving with respect to a contact surface, a method for monitoring events correlated with interactions between tyres of a moving vehicle and a contact surface, and related systems, tyres, methods, and vehicles are also disclosed.
