10. The vision system of claim 1 , wherein said control puts the HVAC system into recirculation mode when, responsive at least in part to image processing of captured image data by said image processor, said control determines that the equipped vehicle is behind another vehicle and is within a selected distance from the other vehicle that is ahead of the equipped vehicle.

11. A vision system for a vehicle, said vision system comprising:

at least one camera disposed at a vehicle equipped with said vision system, wherein said at least one camera has a field of view exterior of the equipped vehicle;

a control comprising an image processor for processing image data captured by said at least one camera;

wherein said control, responsive at least in part to image processing of captured image data by said image processor, is operable to at least one of (i) control an HVAC system of the equipped vehicle responsive to a type of vehicle detected exterior of the equipped vehicle, (ii) control an HVAC system of the equipped vehicle responsive to a vehicle detected exterior of the equipped vehicle being within a threshold distance of the equipped vehicle and (iii) control an HVAC system of the equipped vehicle responsive to detection of a construction zone; and

wherein, responsive at least in part to image processing of captured image data by said image processor, said control determines that the equipped vehicle is behind another vehicle and is within a selected distance from the other vehicle that is ahead of the equipped vehicle and, responsive to said determination, at least one of (i) puts the HVAC system of the equipped vehicle into recirculation mode and (ii) closes a window of the equipped vehicle if the window is open.

12. The vision system of claim 11 , wherein the selected distance from the other vehicle to the equipped vehicle is larger if the other vehicle is a truck rather than a car.

13. The vision system of claim 11 , wherein said control, responsive at least in part to image processing of captured image data by said image processor, is operable to control the HVAC system of the equipped vehicle responsive to detection of a construction zone.

14. A vision system for a vehicle, said vision system comprising:

at least one camera disposed at a vehicle equipped with said vision system, wherein said at least one camera has a field of view exterior of the equipped vehicle;

a control comprising an image processor for processing image data captured by said at least one camera;

wherein said at least one camera comprises a forward-viewing camera having a forward field of view ahead of the equipped vehicle;

wherein said control, responsive at least in part to image processing of captured image data by said image processor, is operable to control an HVAC system of the equipped vehicle responsive to a vehicle detected ahead of the equipped vehicle being within a threshold distance ahead of the equipped vehicle; and

wherein said control puts the HVAC system into recirculation mode when the detected vehicle is a selected distance ahead of the equipped vehicle.

15. The vision system of claim 14 , wherein the selected distance from the detected vehicle to the equipped vehicle is larger if the other vehicle is a truck rather than a car.

16. A vision system for a vehicle, said vision system comprising:

at least one camera disposed at a vehicle equipped with said vision system, wherein said at least one camera has a field of view exterior of the equipped vehicle;

a control comprising an image processor for processing image data captured by said at least one camera;

wherein said at least one camera comprises a forward-viewing camera having a forward field of view ahead of the equipped vehicle;

wherein said control, responsive at least in part to image processing of captured image data by said image processor, is operable to control an HVAC system of the equipped vehicle responsive to a vehicle detected ahead of the equipped vehicle being within a threshold distance ahead of the equipped vehicle; and

wherein said control, responsive at least in part to image processing of captured image data by said image processor, determines that the equipped vehicle is behind another vehicle and is within a selected distance from the other vehicle that is ahead of the equipped vehicle and, responsive to said determination, at least one of (i) puts the HVAC system into recirculation mode and (ii) closes a window of the equipped vehicle if the window is open.
