Abstract
An electric vehicle includes a traction motor, an inverter that supplies the motor with an alternating current, three current sensors that respectively measure current of each phase of the alternating current output by the inverter, the alternating current being a three phase alternating current; and a controller that controls the motor through the inverter. The controller is configured to, when one of the current sensors becomes unusable, identify the unusable current sensor while controlling the motor with a d-axis voltage command value set to zero and a q-axis voltage command value set to a non-zero value.
