Abstract

La présente invention a pour objet un procédé de calibration d’une première loi de passage de rapport de vitesse pour une chaine de traction de véhicule automobile comportant un moteur thermique et une boite de vitesses automatique. Le procédé vise à améliorer le comportement vibratoire de la chaine de traction et comporte à cet effet les étapes de détermination (E1) d’une valeur de régime moteur correspondant à un régime d’excitation du mode propre de la chaine de traction, de comparaison (E2) du champ de fonctionnement en régime moteur de la première loi de passage et de ladite valeur de régime d’excitation, de création (E3) d’une deuxième loi de passage, à partir de la première loi, dont le champ de fonctionnement en régime exclut la valeur de régime d’excitation du mode propre. L’invention concerne les boites de vitesses pilotées et robotisées pour véhicule thermique et hybride. Figure 2The subject of the present invention is a method for calibrating a first gear ratio change law for a motor vehicle traction chain comprising a combustion engine and an automatic gearbox. The method aims to improve the vibratory behavior of the traction chain and for this purpose comprises the steps of determining (E1) an engine speed value corresponding to an excitation speed of the natural mode of the traction chain, of comparison (E2) of the operating field at engine speed of the first switching law and of said excitation speed value, creating (E3) a second switching law, from the first law, whose steady state operation excludes the eigenmode excitation steady state value. The invention relates to controlled and robotized gearboxes for thermal and hybrid vehicles. Figure 2
