Abstract
A system for determining interaction between a tire 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 tire. The at least one first sensor supplies a first signal to the processing means. The first signal is generated by rotation of the tire and is generated cyclically with each revolution of the tire. The processing means detects variations in time intervals between distinctive elements of the first signal. A tire including the system, a kit for detecting behavior of a tire moving with respect to a contact surface, a method for monitoring events correlated with interactions between tires of a moving vehicle and a contact surface, and related systems, tires, methods, and vehicles are also disclosed.
