WORK VEHICLE HVAC CONTROL BASED ON OPERATOR SEAT DIRECTION

摘要

An HVAC control system for directing the flow of air in a work vehicle's HVAC system responds to the orientation of a rotating seat within the work vehicle's cabin. The seat may rotate between at least two operational positions, such that the operator of the work vehicle may control a forward or a rearward implement. The HVAC control system includes one or more detectors for detecting the position of the seat. A control module receives output from the detectors and allows or prevents the flow of air through particular ducts in the HVAC system based on the seat's position. The control module may actuate one or more doors to open and close ducts as needed. The control module may operate a first door to open or close forward ducts and a second door to open or close rearward ducts depending on whether the seat is facing forward or rearward.

主权项

1. In a work vehicle having a seat that rotates between a first operational position and a second operational position, and further having an HVAC system having at least a first duct for directing air at a first area and a second duct for directing air at a second area distinct from the first area, a control system comprising:
a first door that prevents air from flowing through the first duct in a closed position and allows air to flow through the first duct in an open position; a first actuator for moving the first door between at least the closed and open positions; a detector for detecting whether the seat is in at least one of the first and second operational positions and generating a position output signal based on the detected operational position; and a control module for driving the first actuator according to the position output signal of the detector.
