ACTIVE AIR SCOOP
An air duct system for a vehicle including at least one active air scoop configured to control air flow to the wheel wells of a vehicle. In some examples, the active air scoop can be positioned at the underbody of the vehicle. In some examples, the air duct system can include a first and second branch directing air to first and second areas of the wheel well. In some examples, the amount of air directed to the first and second branch are controlled by the active scoop and/or one or more valves in the air duct. In some examples, the active air scoop can be controlled based on one or more temperature measurements in the wheel well.

8 . The air duct system of claim 7 , wherein the active air scoop is further configured to allow air flow to the first outlet and not the second outlet when the active air scoop is in the closed position.
9 . The air duct system of claim 8 , wherein the first outlet directs air to a low-pressure region of the vehicle.
10 . The air duct system of claim 3 further comprising one or more sensors and a controller, wherein
the plurality of positions of the active air scoop are controlled by the controller based on data from the one or more sensors.
11 . The air duct system of claim 1 , further comprising a valve configured to be moved to a plurality of positions, wherein
the valve is positioned in the channel between the inlet and the first and second branch, and the valve is configured to control a first amount of air flow to the first branch and a second amount of air flow to the second branch based on the plurality of positions of the valve.
12 . The air duct system of claim 11 further comprising one or more sensors and a controller, wherein
the plurality of positions of the valve are controlled by the controller based on data from the one or more sensors.
13 . An active cooling system for a vehicle comprising:
an air duct capable of directing a flow of air to a wheel well of the vehicle;
an active air scoop positioned in front of the wheel well and hinged at a pivot point located on a side of the active air scoop nearest to the wheel well, wherein the active air scoop is configured to control an amount of air flow to the air duct;
a thermal sensing system configured to determine the temperature of at least one zone within the wheel well; wherein the active air scoop is controlled based on data from the thermal sensing system.
14 . The active cooling system of claim 13 , further comprising one or more actuators connected to the active air scoop, wherein
the one or more actuators are configured to move the active air scoop to a plurality of positions including a first closed position and a second open position.
15 . The active cooling system of claim 13 , further comprising:
a second active air scoop positioned in front of a second wheel well of the vehicle, the second wheel well being on a side of the vehicle opposite the wheel well, wherein
the thermal sensing system is further configured to determine the temperature of at least one zone within the second wheel well, and
the second active air scoop is controlled based on data from the thermal sensing system.
16 . The active cooling system of claim 13 , wherein
the air duct comprises:
a channel capable of directing the flow of air;
an inlet defining a first end of the channel,
a first branch extending from the channel and terminating at a first outlet;
