A vehicle air-conditioning control system includes a controller that controls a blow outlet drive device and a plate member drive device based on a sensed result of a seat back state sensing device. When a reclined state of the seat back is sensed, the controller controls the blow outlet drive device and thereby places an air-flow direction change mechanism in a predetermined position to direct conditioning air, which is blown from the blow outlet, such that the conditioning air collides to a plate surface of a plate member. At this time, the controller also controls the plate member drive device to place the plate member in a predetermined position, so that the conditioning air, which collides to the plate surface of the plate member, reaches a specific part of an occupant who is on the seat having the seat back placed in the reclined state.
