Abstract
An electrified vehicle disclosed in the present specification includes: a motor configured to rotate a drive wheel of the electrified vehicle; a sensor configured to detect a motor rotation number that is the number of rotations of the motor; and a control device configured to perform feedback control of the motor rotation number based on a value detected by the sensor. The control device is configured to perform during the feedback control a process of extracting a vibration component in a predetermined frequency band from the value detected by the sensor, a process of calculating an integrated value by integrating the extracted vibration component for a predetermined period, and a process of determining whether the calculated integrated value falls within a predetermined abnormal range.
