Abstract

La présente invention se rapporte à un système de commande de changement de vitesse pour transmission automatique. Selon l'invention, à un certain nombre de sous-intervalles pendant un intervalle fixe de temps, la vitesse et l'ouverture d'un papillon valve sont séquentielement accumulées. Les valeurs moyennes de la vitesse et de l'ouverture du papillon dérivées à chaque intervalle fixe sont utilisées avec une accélération moyenne associée, qui sont obtenues par une unité centrale de traitement 1, une mémoire à accès aléatoire 2 et une mémoire morte 3, pour choisir un motif correct de changement de vitesse correspondant bien à la condition réelle de fonctionnement d'un véhicule. L'invention s'applique notamment à l'industrie automobile.
