Start and stop blower map based on sunload to improve fuel economy

A control system for a vehicle, comprising:

• one or more sensors configured to measure an amount of thermal energy;
• a heating, ventilation and air conditioning (HVAC) unit configured to output or circulate air having an airflow rate within the vehicle;
• a memory for storing a plurality of blower maps that associate the airflow rate with an expected temperature;
• and
• a processor connected to the one or more sensors and the HVAC unit and configured to:
• obtain, from the one or more sensors, the amount of thermal energy,
• obtain, from the memory, a blower map from the plurality of blower maps based on the amount of thermal energy,
• determine the airflow rate based on the blower map and the expected temperature, and
• increase or decrease, using the HVAC unit, the airflow rate to adjust a temperature within the vehicle to the expected temperature.

A method for controlling a temperature within a vehicle, comprising:

• obtaining, by a processor and from one or more sensors, an amount of sunload energy;
• obtaining, by a processor and from memory, a blower map from a plurality of blower maps based on the amount of sunload energy;
• determining, by the processor, an airflow rate based on the blower map and an expected temperature;
• and
• controlling, by the processor and using a heating, ventilation and air condition (HVAC) unit, the airflow rate to adjust a temperature within the vehicle to the expected temperature.
