Abstract
Methods, systems, and apparatus for a control system that improves defroster performance in a vehicle by reducing rear heater core heat rejection to increase heat availability to the defroster. The control system includes a rear heating, ventilation and air conditioning (HVAC) unit configured that moves air into the vehicle. The control systemincludes a memory for storing multiple blower maps. The control system includes an electronic control unit connected to the rear HVAC unit and memory. The electronic control unit is configured to determine a mode for a front HVAC. The electronic control unit is configured to obtain from the memory a blower map for the rear HVAC unit from the multiple blower maps based on the mode. The electronic control unit is configured to determine an airflow rate for the air based on the obtained blower map and control an amount of air outputted.
