A method of controlling an apparatus of multi-air mode for an air conditioner of a vehicle includes turning on power to the air conditioner, by a driver using an air conditioner operation unit provided in the vehicle. The method includes: determining, by a controller, whether a driver has turned on a multi-air mode through the air conditioner operation unit; in response to determining that the multi-air mode is turned on, operating, by the controller, the air conditioner in the multi-air mode; determining, by the controller, whether an intensity of air discharged from the air conditioner is greater than or equal to a first stage; and in response to determining that the intensity of air discharged from the air conditioner is greater than or equal to the first stage, automatically adjusting, by the controller, the intensity of the air to a second stage less than the first stage.

A road vehicle having: a passenger compartment in which a transmission tunnel is present, a right rear seat and a left rear seat; and an air conditioning system of the passenger compartment. The air conditioning system has: a rear body that is arranged in the centre of the passenger compartment at the transmission tunnel and in front of the rear seats; two air vents that are obtained in the rear body and are arranged side by side one towards the right and one towards the left, respectively; an air treatment unit that is connected to the two air vents; a single common supply duct that originates from the air treatment unit; a bifurcation that connects the common supply duct to the two air vents; a blade that is arranged in the area of the bifurcation and is movable between a completely closed position of a right branch of the bifurcation and a completely closed position of a left branch of the bifurcation; and an electric actuator configured to move the blade.

An air outlet for a vehicle includes a first and second side walls each having upper and lower slots. Flexible upper and lower walls each have divider slots. The flexible upper wall engaging the first upper slots. The flexible lower wall engaging the lower slots. A coupling member couples a center portion of the flexible upper wall to a center portion of the flexible lower wall. The outlet has a plurality of divider walls. Each divider wall of the plurality of divider walls has a plurality of divider plates. Each divider wall is coupled between one of the first plurality of divider slots and one of the second plurality of divider slots. A control arm is coupled to one of the flexible upper wall or the flexible lower wall. The control arm moves the flexible upper wall, the flexible lower wall and the plurality of divider walls simultaneously.
