A method of controlling power of a vehicle includes an individual device provided on each seat of the vehicle to be independently operated by an occupant of a corresponding seat, for detecting whether the occupant is present in each seat of the vehicle and turning off the individual device provided on the corresponding seat when a vacant seat in which no occupant is present is detected.

Disclosed herein is an apparatus for rear seat detection. The apparatus may include: an indoor camera configured to provide image data; an indoor radar configured to provide radar data; a controller including a first processor and a second processor. The first processor configured to obtain information on a change in a front passenger seat and a rear seat of a vehicle based on processing the image data. The second processor configured to obtain motion information on an object in the rear seat of the vehicle based on processing the radar data. The first controller may identify a change of a detection area in the rear seat, and determine whether a human is seated in the rear seat of the vehicle.
