Method for pre-cooling automotive vehicle passenger compartment
First Claim
1. A method for pre-cooling a passenger compartment of an automotive vehicle, the vehicle including at least one electrically actuatable window and a HVAC system having at least a controller, a blower, at least one temperature sensor in the passenger compartment, and a HVAC ducting leading to the passenger compartment, said controller and said blower connected to a vehicle battery, comprising the steps of:
- a) determining the temperature of the passenger compartment and comparing the temperature to a first predetermined value;
b) cycling an inlet of said blower to an outside air intake position and operating said blower to provide pressurized air through said HVAC ducting to said passenger compartment of said vehicle if said temperature of said passenger compartment is greater than said first predetermined value;
c) opening said windows of said vehicle;
d) comparing the temperature of the passenger compartment to a second predetermined value; and
e) stopping operation of the blower when a fuel door open signal is detected.

Abstract
The present invention concerns a method for pre-cooling the passenger compartment of an automotive vehicle. The vehicle includes at least one electrically actuatable window and a HVAC system having at least a controller, a blower, a passenger compartment temperature sensor, and a HVAC ducting leading to the passenger compartment. The controller and the blower are connected to a vehicle battery. The method includes determining the passenger compartment temperature and comparing the temperature to a first predetermined value; cycling an blower inlet to an outside air intake position and operating the blower to provide pressurized air to the passenger compartment if the passenger compartment temperature is greater than the first predetermined value; opening the vehicle windows; comparing the passenger compartment temperature to a second predetermined value; and stopping operation of the blower when the passenger compartment temperature drops below the second predetermined value.

12. A method for pre-cooling a passenger compartment of an automotive vehicle, the vehicle including at least one electrically actuatable window and a HVAC system having at least a controller, a blower, a refrigerant compressor, at least one temperature sensor in the passenger compartment, and a HVAC ducting leading to the passenger compartment, said controller, said blower, and said compressor connected to a vehicle battery, comprising the steps of:
-
a) initiating a cooldown sequence; b) determining the temperature of said passenger compartment and compared the temperature to a first predetermined value; c) cycling an inlet of said blower to a recirculation position if said temperature of said passenger compartment is greater than said first predetermined value; d) opening said windows of said vehicle; e) operating said blower to provide pressurized air through said HVAC ducting to the interior of said vehicle; f) operating said refrigerant compressor; g) monitoring a power level of said vehicle battery; h) comparing the temperature of the passenger compartment to a second predetermined value; and i) stopping operation of said blower and said compressor when one of a hood open signal and a fuel door open signal is detected by said controller. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for pre-cooling the passenger compartment of an automotive vehicle, the vehicle including at least one electrically actuatable window and a HVAC system having at least a controller, a blower, a refrigerant compressor, at least one temperature sensor in the passenger compartment, and HVAC ducting leading to the passenger compartment, said controller, said blower, and said compressor connected to a vehicle battery comprising the steps of:
-
a) providing a remote communicator; b) initiating a command from said remote communicator to said controller to initiate a cooldown sequence; c) determining the temperature of the passenger compartment and compared the temperature to a first predetermined value; d) cycling an inlet of said blower to a recirculation position if said temperature of said passenger compartment is greater than said first predetermined value; e) opening said windows of said vehicle; f) operating said blower to provide pressurized air through said HVAC ducting to the interior of said vehicle; g) operating said refrigerant compressor; h) monitoring a power level of said vehicle battery; i) comparing the temperature of the passenger compartment to a second predetermined value; and j) stopping operation of said blower and said compressor when a hood open signal is detected. - View Dependent Claims (20)
