Abstract

La présente invention concerne un procédé permettant de faire fonctionner un système avec au moins une partie mobile. L"invention a pour objet de permettre de commander de manière variable, fiable et précise le déroulement du processus d"actionnement séparé en au moins deux mouvements partiels successifs, celui-ci restant cependant simple et économique. Pour cela, on associe au processus d"actionnement qui se déroule au moyen d"éléments d"actionnement et qui est détecté par des capteurs de position, un tableau des séquences comprenant au moins un séquence binaire pour chaque mouvement partiel du processus d"actionnement, ces séquences binaires permettant de commander le déroulement des mouvements partiels. Cette invention concerne également un procédé permettant de faire fonctionner le toit ouvrant d"un véhicule.
