Title
(EN) DEVICE FOR CONTROLLING THE SPEED OF AN ELECTRIC PROPULSION MACHINE AND CORRESPONDING MACHINE
(FR) DISPOSITIF DE COMMANDE DE LA VITESSE D'UN ENGIN A PROPULSION ELECTRIQUE ET ENGIN CORRESPONDANT
Abstract
(EN)
The invention concerns a device (2) for controlling a machine comprising an electric motor (1), comprising a control system (21, 22, 23) provided with a lever of levers that can be moved between a minimum control position and a maximum control position, and a control unit (3) for the motor. Said control unit (3) comprises means (31) for acquiring a signal representative of the position of said control system, means (32) for determining a target speed value corresponding to said acquired signal, on the basis of a maximum target speed value associated with the maximum control position, and means (33) for controlling the motor on the basis of the determined target speed. Said control device comprises adjustment means (34) arranged with the lever or levers of the system to allow the value of said maximum target speed to be adjusted without removing the hand from the lever or levers. The invention also concerns a corresponding machine.
(FR)
L'invention concerne un dispositif de commande (2) d'un engin comprenant un moteur (1 ) électrique, comprenant un système de commande (21, 22, 23) muni de manette(s) déplaçable(s) entre une position de commande minimale et une position de commande maximale, et une unité de pilotage (3) du moteur. Ladite unité de pilotage (3) comprend des moyens d'acquisition (31 ) d'un signal représentatif de la position dudit système de commande, des moyens de détermination (32) d'une valeur de vitesse de consigne correspondant audit signal acquis, en fonction d'une valeur de vitesse de consigne maximale associée à la position de commande maximale, et des moyens de pilotage (33) du moteur en fonction de la vitesse de consigne déterminée. Ledit dispositif de commande comprend des moyens de réglage (34) agencés avec la ou les manettes du système pour permettre de régler la valeur de ladite vitesse de consigne maximale sans retirer la main de la ou des manettes. L'invention concerne également un engin correspondant.
