Abstract: A system is disclosed. The system includes a climate condition determination module that is configured to determine a climate condition associated with a vehicle based upon an external air temperature or a dew point temperature. The system also includes a compressor operational state control module that is configured to control a plurality of operational states of a variable displacement compressor of a heating, ventilation and air conditioning system within the vehicle. The compressor operational state control module is configured to cause the variable displacement compressor to selectively transition from a variable displacement operational state to a fixed displacement-like operational state when the climate condition exceeds a climate threshold to cause an evaporator of the heating, ventilation and air conditioning system to provide evaporator air having an air temperature corresponding to a target evaporator air temperature.

Abstract: Methods and systems are provided for estimating a temperature of a cabin of a vehicle and using the estimated cabin temperature. The methods and systems obtain, via at least one temperature sensor, a surface temperature of at least a first internal surface of the cabin of the vehicle. The methods and systems estimate, via a processor and using at least the obtained surface temperature, the heat transfer from the at least one surface to cabin air within the cabin. The methods and systems estimate, via a processor and using at least the estimated heat transfer, the cabin temperature of the vehicle. The methods and systems use the estimated cabin temperature of the vehicle to control at least one feature of an air conditioning module of the vehicle.

Abstract: A thermal management system includes a coolant pump, high-voltage electric heater (HEH) for heating the coolant, a heater core, a blower directing air to the heater core, a cabin heater valve (CHV), sensors, and a controller. The CHV has an Engine Bypass position blocking coolant flow from the HEH into the engine, and an Engine Link position directing coolant from the HEH into the engine. In a method, the sensors measure engine outlet coolant temperature (ECT), inlet coolant temperature (ICT) to the HEH, inlet air temperature into the heater core, and outlet air temperature from the heater core. The controller calculates a target coolant temperature (TCT) value as a function of the air temperatures and mass flow rates, and controls the CHV via position control signals such that the CHV is switched between the Engine Link position and the Engine Bypass position when ICT equals the calculated TCT value.

Abstract: A method of providing automatic climate control. A set point temperature input setting may be read. A cabin equivalent homogeneous temperature, computed real-time, may be compared to the set point temperature. A control value may be determined to equalize the cabin equivalent homogeneous temperature with the set point temperature.
