VEHICLE DOOR CLOSURE CABIN PRESSURE RELIEF SYSTEM

An active pressure relief system for a vehicle cabin in response to a cabin-door closure. An air-extractor may be configured to open when a cabin-door is opened, and remain open until the last of a number of cabin-doors are closed. The air-extractor allows for the increased pressure resulting from the cabin-door closure to be equalized with the external environment through the air-extractor. After the last of a number of cabin-doors are closed, the air-extractor closes to inhibit noise and external elements from entering the cabin through the air-extractor.
