Abstract[English]
The present invention relates to a control device for a transmission, which comprises two motion transmission paths (TR1, TR2), one with a one-way coupling (10) and one with a driven coupling (12). The control device controls the driven coupling (12) to move into the open position depending on the speed of rotation of the secondary shaft of the transmission and its relative direction of rotation between the pinion (toothed wheel) and shaft which are connected by the one-way coupling (with respect to the direction of drive of the one-way coupling). In addition, the control device controls the driven coupling (12) to move into the closed position when the relative direction of rotation of the shaft is in the reverse direction to the direction of drive of the one-way coupling, so as to assist the performance of the transmission for recovering energy via the electric machine.[French]
La présente invention concerne un dispositif de contrôle d'une transmission, qui comporte deux voies de transmission de mouvement (TR1, TR2), un avec un accouplement unidirectionnel (10) et un avec un accouplement piloté (12) Le dispositif de contrôle commande l'accouplement piloté (12) en position ouverte en fonction de la vitesse de rotation de l'arbre secondaire de la transmission, et de son sens de rotation relatif entre pignon (roue dentée) et arbre liés par l'accouplement unidirectionnel (par rapport au sens d'entraînement de l'accouplement unidirectionnel). De plus, le dispositif de contrôle commande l'accouplement piloté (12) en position fermée lorsque le sens de rotation relatif de l'arbre est dans le sens inverse de l'entraînement de l'accouplement unidirectionnel, de manière à favoriser les performances de la transmission pour la récupération d'énergie par la machine électrique.
