1. A vehicle, comprising:
- an electrically powered machine;
a parking gear mechanically connected to the electrically powered machine;
a parking lock mechanism that locks the parking gear;
a sensor that detects a rotor position of the electrically powered machine; and
a controller that;
reads the rotor position when a parking range is selected; and
judges, on the basis of a change in the rotor position, whether a failure has occurred in the parking lock mechanism.
