The control head partially or fully surrounds the air vent and includes HVAC setting selection mechanisms. Activation of a respective one of the selection mechanisms causes a desired setting of the HVAC system to be communicated to the controller to request a particular control setting of the HVAC system. The control head may include a bezel adjacent to the selection mechanisms and display screens which flank the vent. The control head may be a touch screen device having a touch control surface, and may be operable for displaying the HVAC setting selection mechanisms via the touch control surface. A vehicle includes a body defining a vehicle interior, the air circulation device, the controller, and the air vent assembly. ## Claims ### Claim 1 A vehicle comprising: a vehicle body defining a vehicle interior with a passenger compartment; a heating, ventilation, and air conditioning (HVAC) system having an air circulation device; a controller configured to: receive desired setting signals of the HVAC system, and transmit corresponding HVAC control setting signals to the HVAC system to control operation of the HVAC system responsive to receiving the desired setting signals, wherein each of the HVAC control setting signals corresponds to a respective one of the received desired setting signals; and an air vent assembly having: a pair of side-by-side air vents in fluid communication with the air circulation device, wherein each of the air vents is configured to direct a supply of air from the air circulation device into the passenger compartment; and an HVAC control head with an inner perimeter edge defining an opening receiving therein and surrounding both of the air vents, wherein the HVAC control head includes an outer perimeter edge and a plurality of HVAC setting selection mechanisms aligned along the outer perimeter edge, wherein an activation of a respective one of the HVAC setting selection mechanisms causes a respective desired setting signal to be communicated to the controller to thereby request transmission, via the controller, of the corresponding HVAC control setting signal to the HVAC system, and wherein the HVAC setting selection mechanisms include two sets of HVAC control buttons positioned side-by-side along the outer perimeter edge, each of the sets of HVAC control buttons being operable to control output of a respective one of the side-by-side air vents. ### Claim 2 (depends on 1) The vehicle of claim 1, wherein the HVAC control head includes a plurality of descriptive labels or icons each corresponding to a function of a respective one of the HVAC setting selection mechanisms. ### Claim 3 (depends on 1) The vehicle of claim 1, wherein the HVAC control head includes a pair of secondary display screens each in communication with the controller and operable to display the HVAC settings. ### Claim 4 (depends on 1) The vehicle of claim 1, wherein the two sets of HVAC control buttons include two identically-configured sets of HVAC control buttons. ### Claim 5 (depends on 1) The vehicle of claim 1, wherein one of the HVAC setting selection mechanisms is a toggle operable for moving in a first direction to cause the corresponding HVAC control signal to be increased, and in a second direction, to cause the corresponding HVAC control setting signal to be decreased. ### Claim 6 (depends on 1) The vehicle of claim 1, wherein the vehicle includes a center stack having a main display screen in communication with the controller, and wherein the controller is programmed to display the requested HVAC setting via the main display screen. ### Claim 7 (depends on 6) The vehicle of claim 6, wherein the vehicle includes a dashboard, and wherein the air vent assembly is positioned in a center stack between the dashboard and the main display screen. ### Claim 8 An air vent assembly for use in a vehicle having a controller, a vehicle compartment, and a heating, ventilation, and air conditioning (HVAC) system that includes an air circulation device, the air vent assembly comprising: a pair of side-by-side air vents each configured to fluidly communicate with the air circulation device of the HVAC system and direct air received therefrom to the vehicle compartment; and an HVAC control head having a bezel, a pair of secondary display screens each configured to communicate with the controller and flanking the air vents, and a plurality of HVAC setting selection mechanisms positioned along an outer perimeter edge of the bezel, the bezel including an inner perimeter edge defining an opening receiving therein and surrounding both of the air vents, wherein an activation of a respective one of the HVAC setting selection mechanisms causes a desired setting signal of the HVAC system to be communicated to the controller to thereby request transmission, by the controller, of a corresponding HVAC control setting signal to the HVAC system to control an operation of the HVAC system and a display of the corresponding desired setting via at least one of the pair of secondary display screens, and wherein the plurality of HVAC setting selection mechanisms includes two sets of HVAC control buttons positioned side-by-side along the outer perimeter edge of the bezel, each of the sets of HVAC control buttons being operable to control output of a respective one of the side-by-side air vents. ### Claim 9 (depends on 8) The air vent assembly of claim 8, wherein at least one of the HVAC setting selection mechanisms is a toggle operable for moving in a first direction to cause the corresponding HVAC control signal to be increased and in a second direction to cause the corresponding HVAC control signal to be decreased. ### Claim 10 (depends on 8) The air vent assembly of claim 8, wherein the HVAC control head includes a touch screen device having a touch control surface, and wherein the HVAC control head is operable for displaying at least some of the HVAC setting selection mechanisms via the touch control surface. ### Claim 11 (depends on 8) The air vent assembly of claim 8, wherein the HVAC control head is a touch screen device with a touch control surface operable for displaying all of the HVAC setting selection mechanisms. ### Claim 12 (depends on 8) The air vent assembly of claim 8, wherein the bezel includes a plurality of labels and/or icons, each of the labels and/or icons identifying a corresponding one of the HVAC setting selection mechanisms. ### Claim 13 (depends on 8) The air vent assembly of claim 8, wherein the HVAC control buttons are arranged side-by-side in series along the outer perimeter edge of the bezel.
