1. A automatic climate control system comprising:
- a compressor;
a blend door;
at least one relative temperature selector; and
a controller coupled to the relative temperature selector and configured to;
receive input from an ambient temperature sensor, a cabin temperature sensor, and the relative temperature selector corresponding to a relative cabin temperature change request; and
output compressor speed and blend door position based on ambient temperature, cabin temperature, and the relative cabin temperature change request.

Abstract
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.

16. A method for operating an automatic climate control system in a vehicle having a compressor, a blend door, and a control head having at least one relative temperature selector for use by an operator of the vehicle, the method comprising:
-
receiving inputs corresponding to an ambient temperature, a cabin temperature, and a relative cabin temperature change selected by the operator; receiving a thermal comfort rating (TCR) based at least in part upon the relative cabin temperature change, wherein the TCR is associated with a range of cabin temperatures; and outputting compressor speed to the compressor and blend door position to the blend door based at least in part upon the ambient temperature, the cabin temperature, and the TCR. - View Dependent Claims (17, 18)
