Title
(EN) ACTUATOR SYSTEM COMPRISING DETECTION MEANS
(FR) SYSTEME ACTUATEUR COMPRENANT UN MOYEN DE DETECTION
Abstract
(EN)
The invention provides an actuator system comprising an actuator member having first and second positions. The system further comprises actuating means for moving the actuator member between the first and second positions and detection means for detecting the first respectively the second position and supplying time signals indicative thereof. A controller determines on the basis of supplied time signals the time lapsed when the actuator member is moved between the first and second positions in a given direction, the controller comprising information representing at least one defined time range, each time range being associated with movement of the actuator member in a given direction between the first and second positions and a given actuation force, the controller being adapted to compare the determined time lapsed with the defined time range(s) and perform an action corresponding to the time range associated with the determined time lapsed.
(FR)
Cette invention se rapporte à un système actuateur, qui comprend un élément actuateur présentant une première et une seconde position. Ce système comprend en outre un moyen d'actionnement destiné à déplacer l'élément actuateur entre la première et la seconde position et un moyen de détection destiné à détecter la première respectivement seconde position et à fournir des signaux de durée indiquant ces positions. Un contrôleur détermine, sur la base de signaux de durée fournies, la durée écoulée depuis le moment où l'élément actuateur s'est déplacé entre la première et la seconde position dans une direction donnée, ce contrôleur contenant des informations qui représentent au moins une plage de durées définie, chaque plage de durées étant associée à un mouvement de l'élément actuateur dans une direction donnée entre la première et la seconde position et une force d'actionnement donnée, ledit contrôleur étant conçu pour comparer la durée écoulée déterminée à la plage/aux plages de durées définies et pour exécuter une action correspondant à la plage de durée associée à la durée écoulée déterminée.
