摘要： A control method for a motor vehicle HVAC system categorizes potentially conflicting override commands for at least one control parameter in order to assign a priority of control. Override commands are categorized as being related to occupant safety, vehicle safety or occupant comfort. Highest priority is assigned to override commands categorized as being related to occupant safety, second-highest priority is assigned to override commands categorized as being related to vehicle safety, and third-highest priority is assigned to override commands categorized as being related to occupant comfort. An HVAC controller carrying out the control method then regulates the control parameter in accordance with the override command that has been assigned the highest priority.

摘要： A HVAC system is operable in a fresh air mode and a recirculation mode for use in a vehicle is disclosed. The HVAC system includes a blower and a HVAC module in fluid communication with and downstream of the blower for warming and cooling the air to be circulated through the passenger compartment in both the fresh air mode and the recirculation mode. The HVAC module includes an inlet duct in fluid communication with and upstream of the blower and located above the dashboard for drawing air from the passenger compartment above the dashboard and through the blower and the HVAC module in the recirculation mode. The inlet duct above the dashboard improves air circulation within the passenger compartment that improves the air warm-up rate. The inlet duct above the dashboard also improves the airflow across a windshield to prevent fogging of the windshield.

摘要： An improved method of electric window heater activation automatically and independently activates front and rear window heaters at a variable level based on the respective potential of fogging, within the ability of the vehicle electrical system to supply the requested current without discharging the storage battery. A defog controller develops front and rear fog factors indicative of the relative potential of fogging, and activates the respective electric heaters as required to drive the respective fog factor to zero. The fog factors are based on an estimate of the cabin air dewpoint temperature, the temperature of the respective window surfaces, and a temperature interval over which the fog factor signals only partial activation of the respective heater. The temperature interval is biased in a direction to provide preventative activation of the heaters at a relatively low level when the electrical power requirement is limited, and the activation level is limited as required to prevent battery discharging.

摘要： An energy-efficient vehicle air conditioning system includes a variable capacity refrigerant compressor having a capacity control valve with integral refrigerant sensors and control circuitry, and a driver interface panel for selecting the discharge air temperature and inlet air source, and for selecting either a normal control mode or an energy-efficient control mode. When the energy-efficient control mode is selected, control setting indicators prompt the driver to request full-cold discharge air temperature and recirculated cabin air, and the control circuitry initiates a compressor capacity control based on the refrigerant sensor information and a measure of the outside air temperature to produce a suitable discharge air temperature at a reduced power consumption level.
