Filed:

Aug 3, 2001

Appl. No.:

09/922034

Inventors:

Wayne Oliver Forrest - Gasport NY
Elliott D. Keen - Lockport NY

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F25D 1704

US Classification:

62186

Abstract:

An improved method of operation for a vehicle air conditioning system controls an inlet air blower motor and an air inlet mixing device to reduce compressor and blower motor power consumption and achieve performance improvements associated with cabin air recirculation while maintaining a predefined level of outside air flow and a predetermined humidity level in the inlet air mixture of the system. The overall air flow is determined by the speed of the blower motor and the speed of the vehicle, and the speed of the blower motor and the position of the inlet air mixing device are adjusted as a function of both the vehicle speed and the selected blower motor speed so that the predefined level of outside air flow is preserved regardless of the vehicle speed and the selected blower motor speed.

Abstract:

An improved, more efficient method of operation for a vehicle heating and air conditioning system electrically positions a temperature control actuator in accordance with a first temperature control schedule for coordinated control of compressor capacity and re-heating of the discharge air when air conditioning is enabled, in accordance with a second temperature control schedule when air conditioning is disabled. Both first and second temperature control schedules position the temperature control actuator as a function of the setting of the driver-manipulated temperature selector. The first control schedule positions the temperature control actuator to provide a linear relationship between the temperature selector setting and the air discharge temperature with coordinated control of the compressor capacity and the temperature control actuator when air conditioning is enabled, and the second control schedule positions the temperature control actuator to provide a linear relationship between the temperature selector setting and the air discharge temperature when air conditioning is disabled.

International Classification:

F25B 13/00
G05D 23/19

US Classification:

62 56, 700 32, 700 42, 700300

Abstract:

A Proportional Integral Derivative (PID) control system controls a component by adjusting the control input and the execution of the PID calculation whenever a change in a state of a component exceeds a certain value.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F25B 4902

US Classification:

62227

Abstract:

An improved vehicle climate control system in which the passenger compartment temperature and humidity are controlled without requiring a humidity sensor. The control is based on the recognition that the air temperature at the evaporator outlet represents the dew point of the air supplied to the passenger compartment, and may be specified based on the desired passenger compartment air temperature to achieve a desired relative humidity in the vehicle once the desired passenger compartment temperature has been achieved. In a first mechanization, the desired relative humidity is predetermined, and the corresponding values of evaporator outlet air temperature are determined as a function of the desired passenger compartment temperature. In a second mechanization, the operator of the vehicle is permitted to select a desired relative humidity, and the corresponding values of evaporator outlet air temperature are determined as a function of the desired passenger compartment temperature and the selected humidity level.

Delphi Technologies, Inc. - Troy MI

International Classification:

F25D 1704

US Classification:

62186

Abstract:

An improved method for controlling inlet air mixing in a vehicle air conditioning system having an air inlet mixing device, wherein the mixing device is controlled under predefined operating conditions to improve vehicle fuel economy and achieve performance improvements associated with cabin air recirculation while maintaining a predefined level of outside air flow in the inlet air mixture of the system. The overall air flow is determined by the speed of an inlet air blower motor, and the control is enabled under high thermal loading to adjust the inlet air mixing device as a function of the blower motor speed so that the predetermined level of outside air flow is preserved regardless of the blower motor speed.

International Classification:

B60J 1/20

Abstract:

A system for vehicular power shade control is provided. The system includes a power shade operable to selectively deploy and retract in relation to a corresponding window of a vehicle, a sensor providing data related to the vehicle, and a computerized power shade controller. The computerized power shade controller operates programming to monitor the data from the sensor, compare the data to a threshold value, and generate a command to the power shade based upon the comparing.
