Method and device for monitoring the instantaneous behaviour of a tyre during the running of a motor vehicle

摘要

A method for monitoring the instantaneous behavior of a tire includes the steps of acquiring and storing at least one basic reference curve representing variation of a displacement of at least one specified point of the tire in at least one of three spatial directions as a function of a spatial position of the at least one specified point during at least one portion of a revolution of the tire, continuously acquiring first signals representing the spatial position of the at least one specified point, deriving from the spatial position signals of the at least one specified point at least one cyclic curve of current operating displacement in at least one spatial direction, continuously comparing the at least one cyclic curve of current operating displacement with the at least one basic reference curve, and emitting a second signal depending on results of the comparison. A related device is also disclosed.
