Title:
【発明の名称】自動車走行時のタイヤの瞬間的な挙動を監視するための方法および装置
Document Type and Number:
Japanese Patent JP2003514707
Kind Code:
A
Abstract:
A method for monitoring the instantaneous behaviour of a tyre (1) during the running of a motor vehicle, comprising the steps of: a) acquiring and storing, at least temporarily, at least one basic reference curve which represents the variation of the displacement of at least one specified point of the said tyre in at least one spatial direction, as a function of the spatial position of the point, in at least one portion of a revolution of the tyre; b) continuously acquiring signals of the position in space of the specified point of the tyre (1); c) deriving from the position signals at least one cyclic curve of operating displacement of the point in the spatial direction, as a function of the spatial position of the point, in at least one portion of a revolution of the tyre; d) continuously comparing the said curve of operating displacement with the said basic reference curve of displacement; and e) emitting a signal depending on the comparison and indicating the instantaneous behaviour of the tyre (1).
