Abstract

L'invention concerne un procédé de pilotage pour désaccoupler l'arbre primaire (1) et l'organe de sortie (14) d'une boîte de vitesses automatique. La boîte de vitesses comprend un train épicycloïdal (4) incluant un planétaire externe (6) solidaire de l'arbre d'entrée (1) et un planétaire interne fixe (5) ainsi qu'un porte satellite (7) portant un satellite (8) engrené dans ces planétaires (5, 6) et dans le planétaire interne (5). Elle comprend un second train épicycloïdal (9) incluant un planétaire externe (14), un petit et un grand planétaire interne (16, 17) et un porte satellite double (11). Le premier satellite (12) est engrené dans le petit planétaire interne (16) et dans le second satellite (13) qui est engrené dans le grand planétaire interne (17) et dans le planétaire externe (14). Deux embrayages (18, 19) permettant de solidariser le porte satellite simple (7) respectivement au petit et au grand planétaire interne (16, 17) sont maintenus ouverts. Un frein (24) permettant de bloquer le porte satellite double (11) est maintenu serré. L'invention s'applique au pilotage d'une telle boîte de vitesses lorsque le véhicule est à l'arrêt.
