METHOD OF MANAGEMENT OF AN ELECTRIC PROPULSION SYSTEM AND ELECTRIC PROPULSION SYSTEM IMPLEMENTING THE METHOD

Electric propulsion system comprising a first and a second propulsion line, operatively connectable individually to a common driving axle, each propulsion line comprising an electric motor, a gearbox comprising at least two gear ratios, a clutch to connect/disconnect the related propulsion line from the driving axle, processing means configured to control the interruption of torque delivery and consequent variation of the transmission ratio first in the propulsion line whose maximum deliverable torque is lower and, at the end of the variation of the transmission ratio, the interruption of torque delivery and consequent variation of the transmission ratio in the other propulsion line.
