Embodiment Construction

[0017] Typically, control of temperature and windshield defogging in a motor vehicle is accomplished through various actuators to adjust the temperature and airflow to the cabin. FIG. 1 schematically shows a system 10 for vehicle environment management according to an embodiment of the present invention. The vehicle includes a heating, ventilation and air conditioning (HVAC) system, generally indicated at 20 . The HVAC system 20 includes an array of air flow doors including defroster panels, door panels, and recirculating air drives or doors 22, 24, and 28, respectively.

[0018] A damper is part of an air circulation system which, as is generally known, is used to direct a conditioned air flow to various locations within the passenger compartment of a vehicle, such as the windshield, the floor or the dashboard. The dampers 22, 24 and 28 may be actuated by vacuum motors (not shown) under various vacuum, partial vacuum, and no vacuum conditions in the conventional manner as sh...

Abstract

A system and method for vehicle environmental management that automatically operates a vehicle climate control system to quickly and efficiently defog from a vehicle window, such as a vehicle windshield, while still maintaining an environmental comfort level as determined by a vehicle occupant Operating under the target or operating close to the target. The method can be performed by an HVAC control system with pre-programmed algorithms set to operate the HVAC to achieve a desired result. A plurality of sensors may provide input to the control system, which may also receive a plurality of operable manual override inputs from a vehicle occupant. Pre-programmed algorithms are set to operate on various inputs to operate the HVAC to achieve the proper balance between occupant comfort and windshield defogging.

Description

technical field [0001] The present invention relates to a system and method for vehicle environmental management. Background technique [0002] In today's vehicles, computerized climate control (also known as automatic climate control, automatic climate control) is becoming more and more common. In some vehicles, the driver simply selects the temperature setting, and the control system operates the climate control system (also known as the climate control system) to achieve the desired temperature. The thermostatic control system controls fan functions and air conditioning systems such as on / off and fan speed. Such temperature control systems also control the position and movement of various air dampers or dampers to control the movement of air through the evaporator core or heater core, air recirculation through the vehicle, fresh air intake , or a combination of these. [0003] Certain computerized climate control systems monitor the temperature and humidity levels of t...
