| 20100072290 | SYSTEM AND METHOD FOR CONTROLLING A CLIMATE CONTROL SYSTEM WITH REMOTE START OPERATION - In at least one embodiment, a system for controlling a vehicle climate control system in response to starting an engine with a remote start operation is provided. The system includes a first sensor for generating a cabin temperature signal indicative of a temperature within the vehicle. The system further includes a controller for controlling idle speed of the engine in response to the cabin temperature signal such that the controlled idle speed enables the climate control system to achieve a desired temperature. | 03-25-2010 |
| 20100190429 | VARIABLE HVAC AIRFLOW CONTROL - A method and apparatus for controlling the air flow entering a passenger compartment of an automotive vehicle. The position of a valve or door in the vehicle air duct system is varied between a full-fresh air position and a full-recirculated air position to produce a controlled relationship between a fan speed selected by a vehicle occupant and a desired air flow rate into the passenger compartment over a wide range of vehicle speeds. | 07-29-2010 |
| 20100274394 | Climate Control Head With Fuel Economy Indicator - A climate control system having a control head including a display providing at least one comfort level indicator and a fuel economy indicator is provided. The comfort level indicator displays a plurality of comfort level settings corresponding to relative thermal comfort in all weather conditions. Each comfort level setting corresponds to a range of temperatures so that once a comfort range is obtained, the climate control system will be reluctant to consume additional energy, thereby maintaining or improving the current fuel economy state. The fuel economy indicator provides for direct communication of the impact of comfort level settings on fuel economy. | 10-28-2010 |
| 20100286830 | Climate Control System And Method For Optimizing Energy Consumption Of A Vehicle - A climate control system and method for optimizing energy consumption in a hybrid electric vehicle (HEV) is provided. By varying evaporator temperatures based on occupant settings and environmental conditions, electric compressor speed can be optimized to provide the necessary cooling capacities resulting in energy savings. Determining the impact that increasing or decreasing engine cooling fan speed has on the overall energy consumption of the climate control system without affecting target discharge air temperature provides for energy saving opportunities. Optimizing energy consumption according to the provided strategy provides for improved fuel economy without sacrificing passenger comfort. | 11-11-2010 |
| 20110082594 | Climate Control System And Method For Optimizing Energy Consumption of A Vehicle - A climate control system includes a control head having a warmer/cooler temperature control for providing relative thermal comfort. A thermal comfort rating (TCR) corresponding to a range of passenger cabin temperatures is determined based upon a comfort level selection by an occupant using the control head. A control strategy employs look-up tables corresponding to the TCR to determine the speed of an electric compressor and the position of a temperature control blend door. The strategy provides for a relatively fast ramp down to a minimum compressor speed to improve fuel economy while maintaining a relative level of thermal comfort. | 04-07-2011 |
