Abstract: A ventilation system is provided for a transportation vehicle having a passenger cabin with an interior trim surface. A stationary duct segment receives an inlet air flow and has a stationary outlet hidden behind the interior trim surface. A telescoping duct segment has a sliding inlet sealingly coupled to the stationary outlet so that it slides on the stationary outlet between a retracted position and an extended position. The telescoping duct segment has a movable outlet arranged to provide a variable flow cross section to the passenger cabin that increases as the telescoping duct segment slides from the retracted position to the extended position. A trim hood provides a portion of the interior trim surface and is movable with the telescoping duct segment. The trim hood has a pivot axis at an end of the trim hood remote from the movable outlet.

Abstract: Each vehicle in a fleet comprises a climate controller having an auto mode. The auto mode controls climate actuators in response to a model relating sensed climate conditions to respective settings for the actuators. The vehicle has a buffer memory periodically storing sample vectors comprised of actuator/operation settings and sensed climate conditions. A user interface in the vehicle is responsive to a user override commands to modify respective operation settings while in auto mode. Each vehicle has a wireless communication system for sending data packages to a remote server when the user generates the override.
