Title
(DE) BETÄTIGUNGSEINRICHTUNG MIT TASTEN
(EN) ACTUATING DEVICE COMPRISING KEYS
(FR) DISPOSITIF D'ACTIONNEMENT A TOUCHES
Abstract
(DE) Die Erfindung betrifft eine Betätigungseinrichtung für ein technisches System, insbesondere zur Auswahl von Schaltstufen eines shift-by-wire- Gangwechselgetriebes. Die Betätigungseinrichtung umfasst eine Tastenanordnung mit zumindest einer Taste (1) sowie Mittel (4) zur Erzeugung elektrischer Steuersignale zur Übertragung an das technische System. Die erfindungsgemäße Betätigungseinrichtung und zeichnet sich dadurch aus, dass zumindest einer Taste bzw. allen Tasten der Betätigungseinrichtung jeweils eine separat steuerbare Sperreinrichtung (2, 3) zugeordnet ist. Die Sperreinrichtung (2, 3) dient der mechanischen Blockierung der jeweiligen Taste (1) und ist mittels Hilfsenergie antreibbar. Die Erfindung ermöglicht dank der Sperrbarkeit der Tasten eine eindeutige taktile Rückmeldung des Systemzustands bzw. der Zulässigkeit des Schaltvorgangs beim Drücken der Tasten. Ferner werden Gefahren, die von für den Bediener nicht erkennbaren Systemzuständen, von unzulässigen Schaltanforderungen bzw. Fehlbetätigungen, von Defekten am gesteuerten System bzw. von einer nicht funktionierenden Signalübertragung zwischen Betätigungseinrichtung und gesteuertem System ausgehen, beseitigt.
(EN) The invention relates to an actuating device for a technical system, especially for selecting shifting stages of a shift-by-wire transmission. Said actuating device comprises a key arrangement with at least one key (1) as well as means (4) for generating electrical control signals that are to be transmitted to the technical system. The inventive actuating device is characterized in that one separately controlled locking mechanism (2, 3) is assigned to at least one key or to all keys, respectively. Said locking mechanism (2, 3) is used for mechanically blocking the respective key (1) and is driven using auxiliary power. The invention makes it possible to obtain an unambiguous tactile feedback of the system state or the admissibility of the shifting process when pressing the keys as said keys can be locked. Furthermore, hazards caused by system states that cannot be recognized by the operator, inadmissible switching requests or maloperation, defects of the controlled system, or malfunctioning signal transmission between the actuating device and the controlled system are eliminated.
(FR) L'invention concerne un dispositif d'actionnement pour un système technique, servant notamment à sélectionner des rapports d'une boîte de vitesse électronique (shift-by-wire). Ce dispositif d'actionnement comprend un ensemble touche présentant au moins une touche (1) ainsi que des moyens (4) servant à produire des signaux de commande électriques destinés à être transmis au système technique. Ce dispositif d'actionnement est caractérisé en ce qu'un dispositif de blocage (2,3), pouvant être commandé de manière séparée, est associé à moins une touche ou à toutes les touches du dispositif d'actionnement. Ce dispositif de blocage (2,3) sert au blocage mécanique de la touche respective (1) et peut être commandé au moyen d'une énergie auxiliaire. L'invention permet, grâce à la possibilité de blocage des touches, une rétroaction tactile de l'état du système ou de la fiabilité du passage de vitesse lors de l'enfoncement des touches. Cela permet d'éviter en outre les risques liés à des états de système ne pouvant pas être reconnus par l'utilisateur, à des demandes de changement de vitesse inadmissibles, à des fausses manoeuvres, à des défauts du système commandé ou à une transmission de signaux défaillante entre le dispositif d'actionnement et le système commandé.
