Vehicle including a cap that is automatically separated from a vehicle body

A vehicle comprising:

• an image acquisition unit;
• a storage configured to store an energy source replenishment path and facial information of an authorized user;
• a plurality of obstacle detectors provided at different positions on a body and configured to detect an obstacle;
• a cap provided on a body of the vehicle and configured to open and close a replenishing port for replenishing an energy source;
• a driving unit allowing the cap to be separated or connected from/to the body;
• and
• a controller configured to:
• identify identification information of obstacle detectors that have outputted a detection signal and a detection order thereof;
• determine a movement path of the user based on the identified identification information and the detection order;
• activate the image acquisition unit in response to determining that the determined movement path coincides with the energy source replenishment path stored in the storage;
• and
• determine that an intention of the user to replenish the energy source exists in response to determining that a face recognized from an image acquired by the activated image acquisition unit corresponds to the facial information of the authorized user stored in the storage.
