Title (EN) RAIL VEHICLE HAVING A STARTING ASSISTANCE FUNCTION BASED ON FRICTIONAL BRAKING FORCES
(FR) VÉHICULE FERROVIAIRE COMPORTANT UNE FONCTION D'AIDE AU DÉMARRAGE SE FONDANT SUR DES FORCES DE FREINAGE PAR FRICTION
(DE) SCHIENENFAHRZEUG MIT EINER AUF REIBUNGSBREMSKRÄFTEN BASIERENDEN ANFAHRHILFEFUNKTION
Abstract:
(EN) The invention relates to a rail vehicle (1), comprising a frictional-force-based braking device (18) controlled by an electronic control device (6), an electric traction drive, which is controlled by the electronic control device (6) and which drives the rail vehicle, and an input device (12), by means of which a first signal (8) representing a starting request can be input into the electronic control device (6), a starting assistance function being implemented in the electronic control device (6), by means of which starting assistance function a release of the frictional-force-based braking device (18) and an activation of the electric traction drive are controlled during a transition from a detected standstill to a driving state when the first signal (8) representing the starting request is received from the input device (12) by the electronic control device (6). According to the invention, a sensor device (48) is provided, which directly or indirectly senses the standstill frictional braking force (FHR) holding the rail vehicle (1) at a detected standstill and/or the standstill frictional braking torque (MHR) holding the rail vehicle (1) at a detected standstill or a standstill variable derived from the standstill frictional braking force and/or from the standstill frictional braking torque and which inputs a third signal (42) dependent on the sensed standstill frictional braking force and/or on the sensed standstill frictional braking torque or on the sensed derived standstill variable into the electronic control device (6), and thereupon the electronic control device (6) controls the frictional-force-based braking device (18) and in particular also the traction drive in accordance with the third signal (42) within the framework of the starting assistance function when the first signal (8) representing the starting request is received by the electronic control device (6).
(FR) L'invention concerne un véhicule ferroviaire (1) comportant un dispositif de freinage (18), se fondant sur des forces de friction, commandé par un dispositif de commande électronique (6), un système de traction électrique, commandé par le dispositif de commande électronique (6), qui entraîne le véhicule ferroviaire, un dispositif d'entrée (12), par lequel un premier signal (8), représentant un souhait de démarrage, pouvant être injecté dans le dispositif de commande électronique (6), une fonction d'aide au démarrage pouvant être implémentée dans le dispositif de commande électronique (6), par laquelle un desserrage du dispositif de freinage (18) se fondant sur des forces de friction et une activation du système de traction électrique sont commandés lors d'une transition entre un état déterminé d'immobilisation et un état de marche, quand sous l'effet du dispositif de commande électronique (6) le premier signal (8) représentant le souhait de démarrage est reçu par le dispositif d'entrée (12). Le dispositif prévoit un dispositif capteur (48), qui enregistre directement ou indirectement la force de freinage par friction (FHR) en cours d'immobilisation, qui maintient le véhicule ferroviaire (1) dans un état d'immobilisation défini, et/ou le couple de freinage par friction (MHR) dans l'état d'immobilisation, qui maintient le véhicule ferroviaire (1) dans un état d'immobilisation défini, ou un paramètre d'immobilisation, qui dérive de la force de freinage par friction dans un état d'immobilisation et/ou du couple de freinage par friction à l'état d'immobilisation, et injecte dans le système de commande électronique (6) un troisième signal (42), qui dépend de la force de freinage par friction à l'état d'immobilisation tel que défini et/ou du couple de freinage par friction à l'état d'immobilisation tel que défini, ou du paramètre d'état d'immobilisation dérivé tel que défini, et en ce que le dispositif de commande électronique (6) commande ensuite, en fonction du troisième signal (42), dans le cadre de la fonction d'aide au démarrage, le dispositif de freinage (18) à base d'une force de friction, quand le dispositif de commande électronique (6) reçoit le premier signal (8) représentant le souhait de démarrage.
