摘要
A railway vehicle comprises a traction system including an asynchronous electric motor or a synchronous electric DC motor operable by an inverter electronic drive system. The vehicle further comprises an electronic control unit coupled to the traction system and configured to receive signals/data/commands indicative of operating conditions of the vehicle and of the traction system and to determine, based on the received signals/data/commands, the occurrence of a coasting condition of the vehicle and the occurrence of an exit condition from the coasting condition of the vehicle. If a coasting condition of the vehicle occurs, the electronic drive system is controlled to cause the electric motor to undergo magnetic flux changes. If an exit condition from the coasting condition occurs, and depending whether the electronic drive system is on or off, the electronic drive system is controlled to increase torque of the electric motor or to reduce magnetic flux reduction.
