Vehicle and method of controlling power thereof

A vehicle comprising:

• an individual device provided on each seat of the vehicle to be independently operated by an occupant of a corresponding seat;
• an occupant detector provided to detect whether the occupant is present inside the vehicle and identify the occupant;
• and
• a controller operatively connected to the individual device and the occupant detector and configured to detect whether the occupant is present in each seat of the vehicle using the occupant detector, and when the controller concludes that a vacant seat in which no occupant is present is detected, turn off the individual device provided on the corresponding seat,
• wherein the controller is further configured to:
• determine whether a new occupant is a same person as a previous occupant of the corresponding seat when the new occupant is accommodated in the vacant seat;
• maintain existing settings of the individual device of the corresponding seat without change of the existing settings to operate the individual device when the controller concludes that the new occupant is the same person as the previous occupant, and
• wherein the controller, only when maintaining a start ON state, detects whether the occupant gets off and gets on the vehicle again and refrains from detecting whether the occupant gets off and gets on the vehicle again when the vehicle is in a start OFF state.

A method of controlling power of a vehicle including an individual device provided on each seat of the vehicle to be independently operated by an occupant of a corresponding seat, the method comprising:

• detecting whether the occupant is present in each seat of the vehicle;
• turning off, by a controller operatively connected to the individual device, the individual device provided on the corresponding seat when a vacant seat in which no occupant is present is detected;
• determining, by the controller, whether a new occupant is a same person as a previous occupant of the corresponding seat when the new occupant is accommodated in the vacant seat;
• outputting, by the controller, a guide message for selecting whether to maintain or change existing settings of the individual device of the corresponding seat when the controller concludes that the new occupant is the same person as the previous occupant;
• maintaining, by the controller, the settings of the individual device of the corresponding seat as the existing settings without change to operate the individual device;
• receiving, by the controller, new settings of the individual device from the new occupant when the controller concludes that the new occupant is not the same person as the previous occupant;
• and
• operating, by the controller, the individual device of the corresponding seat based on the new settings of the individual device,
• wherein the controller, only when maintaining a start ON state, detects whether the occupant gets off and gets on the vehicle again and refrains from detecting whether the occupant gets off and gets on the vehicle again when the vehicle is in a start OFF state.
