An electric vehicle control device according to one embodiment includes a plurality of motors capable of transmitting motive power to a wheel of an electric vehicle and an inverter that supplies electric power to drive the motors. A controller controls the inverter and compares, when the electric vehicle drives under a certain velocity condition, a q-axis voltage feedforward value VqFF and a q-axis voltage command value Vq* used for controlling the driving of the motors, to detect an occurrence of miswire between the motors and the inverter when VqFF ‰¥ 1.5·Vq* is satisfied. The controller can thus detect a miswire between the motors and the inverter which are mounted on the electric vehicle to drive the wheels of the electric vehicle.
