摘要： The invention relates to a railway vehicle comprising a traction system, which includes an asynchronous electric motor or a synchronous electric DC motor operable by an inverter or chopper-type electronic drive system. Said railway vehicle also comprises an electronic control unit coupled to the traction system and configured to: receive signals/data/commands indicative of operating conditions of the railway vehicle and of the traction system; determine, on the basis of the received signals/data/commands, the occurrence of a coasting condition of the railway vehicle and the occurrence of an exit condition from the coasting condition of the railway vehicle (block 66); if it determines the occurrence of a coasting condition of the railway vehicle, control the operation of the electronic drive system so as to cause the electric motor to undergo a magnetic flux reduction (block 67), and, during, said magnetic flux reduction of the electric motor, monitor the magnetic flux of the electric motor (block 67), determine whether the magnetic flux of the electric motor decreases below a magnetic flux threshold (block 68), and, if it determines that the magnetic flux of. the electric motor has decreased below said magnetic flux threshold, switch off the electronic drive system (block 69); if it determines the occurrence of an exit condition from the coasting condition of the railway vehicle, determine whether the electronic drive system is on or off (block 44); if it determines the occurrence of an exit condition from the coasting condition of the railway vehicle and it determines also that the electronic drive system is on, causing the torque of the electric motor to start increasing (block 65); if it determines the occurrence of an exit condition from the coasting condition of the railway vehicle and it determines also that the electronic drive system is off, switch on the electronic drive system, control the operation of the electronic drive system so that the electric motor undergoes magnetic flux reduction (block 63), and, during said magnetic flux reduction of the electric motor, monitor the magnetic flux of the electric motor (block 63), determine whether the magnetic flux of the electric motor exceeds said magnetic flux threshold (block 64), and, if it determines that the magnetic flux of the electric motor has exceeded said magnetic flux threshold, cause the torque of the electric motor to start increasing (block 65).
