<p>A control device for an electric railway car including a master controller (1), for providing operating instructions, a running direction detector (2, 3) for detecting the present running direction of the car, and inverter (5) for driving a main AC electric motor (6), and a control mode selector (4) which compares an operating instruction provided by the master controller (1) with the output signal provided by the running direction detector (2, 3). When the operating instruction is not in agreement with the running direction of the output signal, the control mode selector (4) applies a braking control instruction to the inverter (5) in conformance with the running direction of the output signal.</p> |
