| description | An electric vehicle controller includes speed sensorless vector control means (11) for estimating the rotating speed of an AC motor (7) from an output voltage command and an output current from a VVVF inverter (6) and controlling the VVVF inverter (6) based on the estimate, overhead wire current detection means (4) for detecting the current flowing through an overhead wire (1), wrong action sensing means (12) for sensing abnormality in the speed sensorless vector control means (11) from the sign of the current flowing through the overhead wire (1) and detected by the overhead wire current detection means (4) when the VVVF inverter (6) is in operation, and gate stop means (13) for stopping the VVVF inverter when the wrong action sensing means (12) senses abnormality. |
