Abstract
An electric vehicle control device includes: a plurality of motors capable of transmitting motive power to a wheel of an electric vehicle; an inverter that supplies electric power to drive the motors; and a controller that 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 driving of the motors, to detect an occurrence of miswire between the motors and the inverter when the following inequation is satisfied: VqFF≥1.5·Vq*.
