DETERMINING METHOD OF THE APPLIED LOAD ON A DRIVEN TIRE

Disclosed is a method for ascertaining a load applied to a pneumatic tire casing of a mounted assembly, comprising the following steps: - acquiring a signal comprising the amplitude of the acceleration in the direction normal to the crown when rolling at the rotational speed W; - determining a refer...

Zusammenfassung:	Disclosed is a method for ascertaining a load applied to a pneumatic tire casing of a mounted assembly, comprising the following steps: - acquiring a signal comprising the amplitude of the acceleration in the direction normal to the crown when rolling at the rotational speed W; - determining a reference acceleration; - identifying a series of increments I; - delimiting the signal between Imin and Imax for constructing a wheel revolution signal; - defining a first energy density S, which is a function of the wheel revolution signal, of the reference acceleration, designated S+ when the wheel revolution signal is greater than a threshold A and S- when it is not; - identifying the deformation Def% of the tire casing generated by the load as a function of the reference acceleration and the first energy density S; - determining the load Z applied using a bijection F comprising the deformation Def% of the tire casing.
