CA 2366051

A method and an apparatus produce current values dependent on the position of the accelerator pedal controlling the power of one or more electric drives for moving a mobile device that is energised by a fuel cell. The time required by the drive or drives to respond to a change in the desired current value produced as a function of the position of the accelerator pedal is kept as small as possible by producing a current value - convertible into a desired torque value - which is held continuously at a value sufficient to ensure that the output voltage of the fuel cell just avoids undershooting a critical limit.

Méthode et appareil pour la production de différentes valeurs de courant en fonction de la position d'une pédale d'accélérateur commandant la puissance d'au moins un entraînement électrique servant au déplacement d'un appareil mobile alimenté par une pile à combustible. Le temps requis par l'entraînement électrique ou les entraînements électriques pour répondre à un changement de la valeur de courant désirée découlant de la position de la pédale d'accélérateur est limité le plus possible par la production d'un courant - qui peut se convertir en un couple d'une valeur désirée - d'une valeur toujours suffisante pour que la tension de sortie de la pile à combustible atteigne tout juste un seuil critique.
