DETERMINATION D'UN COUPLE DANS UNE CHAINE DE TRANSMISSION DE VEHICULE AUTOMOBILE

Abstract : The invention relates to a method for determining torque (Ce) in a motor vehicle power transmission chain (1), in which a gearbox (5) capable of coupling the output shaft with the input shaft is used. The method comprises: measuring a rotation speed (Wp) of the input shaft; measuring a rotation speed (Wv) of the output shaft; and providing a computer-implemented digital model (32a, 32b) that simulates the power transmission chain by means of a torsion deformation system. The digital model comprises a plurality of state variables (X) exhaustively selected from within the set consisting of: the rotation speed (Wp) of the input shaft; the rotation speed (Wv) of the output shaft; the input torque (Ce) controlling the input shaft; every order of time derivative and time integral of the preceding variables; and the combinations of the preceding variables and every order of the time derivatives and time integrals thereof.
