Abstract
A vehicle heating, ventilating, and air conditioning (HVAC) system can reduce a load applied to a vehicle powertrain during certain conditions. The system can include a fixed compressor operable between an ON state and in an OFF state. Systems and methods can determine whether an engine water temperature meets a forced HVAC recirculation intake threshold. Responsive to determining that the engine water temperature meets the forced HVAC recirculation intake threshold, it can be determined if the engine water temperature meets a high water temperature threshold. Responsive to determining that the engine water temperature meets the high water temperature threshold, it can be determined if a vehicle pitch meets a vehicle pitch threshold. Responsive to determining that the vehicle pitch does not meet the vehicle pitch threshold, the compressor can be operated according to an AC cut cycle.
