Back office optimization of vehicle HVAC control

A vehicle having optimized vehicle heating, ventilation, and cooling (HVAC) settings, comprising:

• a heating apparatus, a cooling apparatus, and at least one heat exchanger configured to provide HVAC resources to a first HVAC circuit, a second HVAC circuit, and a third HVAC circuit;
• a HVAC control module connected to the hearing apparatus, cooling apparatus, heat exchanger, first HVAC circuit, second HVAC circuit, and third HVAC circuit, and configured to allocate the HVAC resources among the first, second, and third HVAC circuits, and a vehicle cabin, wherein cabin temperature is adjusted via the first HVAC circuit, a battery, wherein battery temperature is adjusted via the second HVAC circuit, a compute system, wherein compute system temperature is adjusted via a third HVAC circuit, wherein the HVAC control module is configured to:
• receive HVAC settings from a dispatch service, the HVAC settings being based on vehicle occupancy, current weather conditions, and forecasted weather conditions, and wherein the HVAC settings include a cabin temperature setting, a battery temperature setting, and a compute system temperature setting, and the HVAC control module being further configured when the occupant is present in the vehicle cabin to:
• control the first HVAC circuit to adjust the cabin temperature to the cabin temperature setting, and control the second HVAC circuit and the third HVAC circuit to allow the battery temperature to change within a battery temperature range and the vehicle compute system temperature to change within a compute temperature range;
• control the second HVAC circuit to adjust the battery temperature to the battery temperature setting when the battery temperature is outside the battery temperature range and, and control the first HVAC circuit to allow the cabin temperature to change up to a maximum acceptable cabin setpoint;
• control the third HVAC circuit to adjust the compute system temperature to the compute system temperature setting when the compute system temperature is outside the compute system temperature range, and control the first HVAC circuit to allow the cabin temperature to change up to the maximum acceptable cabin setpoint;
• and
• when the vehicle is unoccupied, the HVAC control module is configured to shut off the first HVAC circuit and divert the HVAC resources of the first HVAC circuit to the second HVAC and the third HVAC circuit to increase cooling of the HV battery and compute system.

A method for optimizing vehicle heating ventilation and air conditioner (HVAC) settings, comprising:

• determining whether an occupant is present in a vehicle;
• when the occupant is present in the vehicle:
• determining whether a high voltage (HV) battery temperature is operating within a first temperature range;
• determining whether a vehicle compute system temperature is operating within a second temperature range;
• when the HV battery temperature is within the first temperature range and the vehicle compute system is within the second temperature range, controlling the HVAC settings to change cabin temperature to a passenger setpoint and allow the HV battery temperature and the vehicle compute system temperature to change;
• when the HV battery temperature is outside the first temperature range, controlling the HVAC settings to degrade cabin temperature to a maximum acceptable setpoint and diverting HVAC resources to adjust the HV battery temperature to within the first temperature range;
• when the vehicle compute system temperature is outside the second temperature range, controlling the HVAC settings to degrade cabin temperature to the maximum acceptable setpoint and diverting HVAC resources to adjust the vehicle compute system temperature to within the second temperature range;
• and
• when the vehicle is unoccupied and outside air temperature exceeds a selected threshold, shutting off a cabin HVAC system, and diverting maximum HVAC resources to adjust the HV battery temperature.
