If a time-synchronized reaching of the reference points is not guaranteed due to disturbances, which act in particular on one or several drives, the drives, which have already reached their reference point, wait until all other drives have also arrived at their reference points.
  • Reasons for not reaching a reference point can be z. As a defect of a drive, a falling below a minimum speed of a drive or the position of a reference point immediately behind a center of gravity of the part to be moved.

Abstract

Dispositif permettant d'actionner des éléments externes mobiles de véhicule, en particulier des éléments de couverture d'un cabriolet, dans lequel des articulations et plusieurs moyens d'entraînement (18, 19, 20, 21, 22) permettent de déplacer des éléments externes de véhicule. Les moyens d'entraînement (18, 19, 20, 21, 22) sont commandés par une unité d'évaluation et de commande supérieure (50). L'unité d'évaluation et de commande (50) calcule et produit, en vue du déplacement d'un élément externe de véhicule le long d'une voie de déplacement prédéfinie par des points de référence pour un moyen d'entraînement (18, 19, 20, 21, 22) donné associé à un élément externe de véhicule, une grandeur de guidage (VF_18, VF_19, VF_20, VF_21, VF_22) qui est déterminée en fonction d'une position (P1, P2, P3, P4, P5) déterminée par capteur des éléments externes de véhicule et de la grandeur de guidage (VF_18, VF_19, VF_20, VF_21, VF_22) produite pour un autre moyen d'entraînement (18, 19, 20, 21, 22).
