Abstract

Ce dispositif, comprenant un générateur de signaux électriques couplé à l'arbre de sortie de la transmission et destiné à engendrer un premier signal dont la fréquence est proportionnelle à la vitesse de l'arbre de sortie de la transmission et dont l'amplitude est fonction de la charge du moteur auquel est associée ladite transmission, et des moyens pour élaborer, à partir de ce signal, les caractéristiques de passage entre les rapports de la transmission, est caractérisé en ce qu'il comporte, en outre, des moyens 1, 2 pour élaborer, à partir du signal du générateur, un signal électrique supplémentaire dont l'amplitude est fonction de la fréquence du premier signal, des moyens 3, 4 de pondération et de comparaison dudit premier signal et dudit signal supplémentaire, en vue d'obtenir un signal représentant périodiquement l'état désiré de la transmission, et des moyens 5 de mémorisation de l'état désiré de la transmission, connectés auxdits moyens de pondération et de comparaison, pour provoquer le passage de la transmission d'un rapport à un rapport voisin en fonction du signal élaboré par lesdits moyens de pondération et de comparaison.
