Devices to Manage Cabin Pressure Response during Automotive Door Closing

Abstract

In the automobile industry, the customers are very sensitive to the feel of their vehicle’s doors. The first signal of vehicle quality is during the customers’ opening and closing of the doors. One method for controlling closing effort is to design extractors that exhaust cabin pressure during closing events. Currently, the vehicle cabin is susceptible to noise from the exterior coming through the air extractor. We are asked to re-design the current air extractors to maintain cabin pressure and ventilation, while preventing noise from entering the vehicle.
