• and
• an authentication device configured to:
• recognize a fingerprint of the user;
• and
• when the fingerprint of the user matches fingerprint information stored in a storage, transmit authentication success information representing user authentication to the driving device and the terminal, wherein the driving device is configured to:
• enter an ignition-on state when a manipulation signal of the start-up button is received within a first predetermined period of time after the authentication success information is received;
• and
• maintain an ignition-off state when the manipulation signal of the start-up button is received after the first predetermined period of time.

A method of controlling a vehicle, the method comprising:

• when a communicator is in a wake-up state and ignition is in an off state, activating an authentication device;
• recognizing a fingerprint of a user through the authentication device;
• when the fingerprint matches fingerprint information stored in a storage, transmitting, authentication success information of the authentication device for user authentication to a driving device;
• displaying ignition-capable information within a first predetermined period of time after the authentication success information is received through a terminal of the vehicle;
• when a manipulation signal of a start-up button is received within the first predetermined period of time, activating the ignition;
• when the manipulation signal of the start-up button is received, maintaining an ignition-off state;
• and
• displaying ignition restriction information corresponding to the ignition-off state through the terminal of the vehicle.
