Method and device for monitoring a behavior of a tire of a vehicle

A method for monitoring a behavior of a tire 2 in a rolling condition comprises the steps of: a) acquiring at S1 a signal (a) rep­resentative of an acceleration of a specified point of the tire; b) deriving at S2 from the signal a curve which represents a profile of the acceleration of the point dur...

description A method for monitoring a behavior of a tire 2 in a rolling condition comprises the steps of: a) acquiring at S1 a signal (a) rep­resentative of an acceleration of a specified point of the tire; b) deriving at S2 from the signal a curve which represents a profile of the acceleration of the point during a revolution of the tire (e.g. fig. 4); c) determining at S3 a leading portion and a trailing portion of the curve, corresponding to an entry and exit point of the footprint region of the tire respectively; d) determining at S4 a first and second measure of a volatility of the signal in the leading and trailing portion; and e) determining at S5 an indication of the behavior of the tire based on the first and second measure. In particular, the method may be used e.g. for aquaplaning warning or e.g. for detection of an offroad condition.
