PROBLEM TO BE SOLVED: To detect erroneous wiring between a plurality of motors which are mounted to an electric vehicle, and drive wheels of the electric vehicle, and an inverter.SOLUTION: An electric vehicle control device of this embodiment comprises a plurality of motors which can transmit power to wheels of the electric vehicle, and an inverter which supplies power for driving a plurality of the motors. A control part controls the inverter, compares a q-axis voltage feedforward value VqFF used for the drive control of the motors in a state that the electric vehicle moves in a prescribed speed condition, and a q-axis voltage command value Vq, and detects that erroneous wiring occurs between the motors and the inverter when the following formula VqFF≥1.5*Vqis satisfied.

    【課題】電気車に搭載され、当該電気車の車輪を駆動する複数台のモータとインバータ間の誤配線を検知する。【解決手段】実施形態の電気車制御装置は、電気車の車輪に動力を伝達可能な複数のモータと、複数のモータを駆動するための電力を供給するインバータと、を備えている。制御部は、インバータを制御するとともに、電気車が所定の速度条件で移動している状態において、モータの駆動制御に用いるq軸電圧フィードフォワード値VqFFと、q軸電圧指令値Vq*と、を比較し、次式、VqFF≧1.5・Vq*を満たしている場合にモータと前記インバータとの間に誤配線が生じていると検出する。【選択図】図2
